HIIT ON PHYSICAL AND MENTAL HEALTH

It is well known that exercise has many health-promoting effects, with improvements of quality of life in a wide range of conditions. Additionally, there is evidence of protective effects against mental disorders, and improvements if used as adjunctive treatment. Generally, it is recommended at least 75-150 minutes of moderate intensity physical exercise per week, although newer guidelines are suggesting even longer times.

In the last few years new approaches to training have appeared, trying to facilitate sports practice in our busy life schedules. One of such varieties is HIIT, that stands for High-Intensity Interval Training.

HIIT is defined as any form of exercise with alternating short bursts of high-intensity exercise (higher than 85% peak heart rate and 80% VO2max). Although we are not going into the many types of HIIT in this entry, they have in common its short duration. Usually a HIIT session can be three times shorter than a traditional Moderate-Intensity Continuous Training session (or MICT).

In our entry we are going to focus on a recent meta-analysis article that has studied the effects of HIIT approaches on health to elucidate if it could be an eligible approach against more traditional practices. Studies with interventions shorter than 2 weeks, or with a frequency inferior to 2 sessions per week were excluded.

From the data extracted in 33 eligible reviews, HIIT participants improved cardiorespiratory fitness, some inflammatory markers and muscle structure when comparing with active controls. The range of benefits was more extensive when comparing with non-active controls, and present across a range of ages going from 6 to 75 years old. Regarding anxiety and depression levels, they improved when compared with pre-training situations (only studied in adults).

Additionally, no acute injuries were reported, and more importantly, adherence rates surpassed 80% in most studies. This high level of adherence is of great interest, as usually sports practice is hard to follow, especially among unaccustomed individuals.

Nevertheless, some adverse effects were also reported with HIIT interventions, but uniquely in patients suffering of cardiometabolic disease, obesity, or chronic obstructive pulmonary disease (COPD). Therefore, the need of more studies on HIIT exercise in these and other diseases.

As for the effects of HIIT on mental health, there were no studies available in people with diagnosed mental illnesses such as major depression, schizophrenia or bipolar disorder, among others. It would be an attractive topic, considering the beneficial effects of HIIT on stress and depressive conditions.

 

Conclusions

  • The data supports the beneficial effects of HIIT exercise along the lifespan in healthy individuals and those suffering of physical, and probably mental, health disorders.
  • When comparing with active controls, HIIT practice improved cardiorespiratory fitness, inflammatory markers and muscle structure more than continuous training sessions.
  • The best health outcomes were obtained with long-interval (more than 2 minutes), high volume (more than 15 minutes) running regimes, conducted 2-3 times per week, for longer than 7 weeks.
  • Because of its high adherence rates (>80%) and short duration, even as short as 10-15 minutes per session, it could be the exercise prescription for certain individuals, although more studies are needed in patients suffering from several conditions.

MARATHON OLYMPIC CHAMPIONS (XV) – Tokyo 1964: ABEBE BIKILA (1932-1973)

Bikila in 1968

 

 

Men of success meet with tragedy. It was the will of God that I won the Olympics, and it was the will of God that I met with my accident. I accepted those victories as I accept this tragedy. I have to accept both circumstances as facts of life and live happily.”

 

Abebe Bikila

As it happened with Rome, Tokyo had already been chosen to host other Olympics earlier, the ones in 1940, but WWII prevented them. Competing with Brussels, Vienna and Detroit Tokyo was awarded the 1964 Games, carrying out an impressive reconstruction and organisational effort.

The latest technology was used: these were the first Olympics with automatic timing and satellite television. Among other curiosities South Africa was suspended because of its apartheid policy, and they saw the first brand war between rival shoe brands Puma and Adidas.

Japan decided to organize an international marathon on the race course one year in advance, where many of the top world marathoners participated. Victory was for New Zealand´s athlete Julian Kilby (2.18.00).

Regarding Bikila, he mostly disappeared from the athletics scene after his victory in Rome. He only competed in the 1963 Boston marathon, where he managed to finish 5th. In the Ethiopian trial marathon, he won in 2.16.18, only 0.4 seconds ahead of his countryman Mamo Wolde, becoming one of the top contenders for victory.

The Olympic marathon was planned for October 21st over a flat course that began and finished in the National Stadium built for the occasion. As a typical autumn day, it was cloudy and humid. The starting field was formed by 68 athletes, and Abebe Bikila was also there shortly after having his appendix removed in mid-September. He had spent a whole week in hospital but seemed recovered enough.

Australian Ron Clarke started aggressively trying to prove himself after his previous defeats in the 10000 and 5000 metres a few days earlier. By the 10k (30.14) Clarke was still in front followed by the Irish Jim Hogan and Bikila, who had started the race cautiously. The small group started falling apart soon. Bikila crossed the 20k in 1.00.58, 5s ahead of Hogan, while Clarke has fallen to third and was pressed by Kokichi Tsuburaya (Japan), József Sütö (Hungary) and Demissie Wolde (Ethiopia).

By the 30k Bikila had opened a gap of 40s with Hogan, himself with 29s of advantage over Tsuburaya and Sütö, just meters behind. Trying to keep close to Bikila had its consequences on Hogan, who retired shortly after the 35k totally exhausted. Nobody seemed able to reach Bikila. His closest opponents were now Tsuburaya, who in the 40k was almost 3 minutes behind, and the British Brian Kilby and Basil Heatley.

Bikila won the race in an astounding 2.12.11, to revalidate his Olympic title and break the world and Olympic records in the process. And he didn´t seem tired, as he started doing some exercises while waiting for his opponents. Local runner Tsuburaya entered the stadium in second position as the spectators thought he would get the silver medal, but a final push by Heatley gave him the second position and relegated Tsuburaya to third. The victory margin from Bikila was more than 4 minutes!!!

Bikila continued running and winning marathons the following years. His sight was on competing in the Olympic Games of 1968 in Mexico, where he would be 36. In 1967 he suffered a hamstring injury in Spain, from which he never fully recovered. Despite it, he was still a favourite for victory when arriving to Mexico in 1968. Unfortunately, just one week before the Olympic race he felt a pain in his leg. It turned to be a stress fracture and was advised to avoid running until marathon day. It wasn´t enough recovery, and he had to abandon the marathon after 15 kilometres.

It would be his last marathon appearance. In 1969 he had a car accident and became quadriplegic. Fortunately, after 8 months of treatment he was able to regain use of his arms, although he was unable to walk again. He had won all but one of the 13 marathons he had completed during his running career.

But his will was strong, and in 1970 he started practicing table tennis and archery and competed in the Stoke Mandeville Games (a precursor of the Paralympic Games). During the Olympics of 1972 in Munich he was guest of honour, receiving a standing ovation during the opening ceremony. He would die one year later, at 41, from a complication of his injuries four years earlier.

Bikila’s legend has perdured until today, as he is the only marathoner capable of winning an Olympic gold medal twice. Next year, in Tokyo Olympics again, Eliud Kipchoge will try the same achievement and revalidate his victory in Rio in 2016. It will be an event to watch. Unfortunately, it won´t happen in Tokyo itself, as the marathon event has been moved to Sapporo.

PHYSIOLOGICAL AND PATHOPHYSIOLOGICAL RESPONSES OF ULTRA-MARATHONS IN NON-ELITE ATHLETES

Image by Skeeze (Pixabay)

It is mostly accepted that running a marathon is a physical challenge, and even more running an ultramarathon, although the physiological effects of running distances longer than 42 kilometres are rarely studied.

A recent article has tried to bring some light into this subject and see how an ultramarathon affects fluid and electrolytes levels, skeletal muscle damage and hepatic and kidney function in non-elite runners.

 

The study

Ten athletes with training volumes between 4 and 15 hours per week fulfilled the inclusion criteria and were included in the study as recreational non-elite individuals.

The race was a mountain ultramarathon, 67km long and with 4500m total ascent and descent in Austria. Food and beverages were provided every 5k.

Blood samples were taken from all individuals the day before the competition, immediately after finishing (within 15 minutes), and 24h later. During competition runners carried a heart rate monitoring device.

 

The results

Body mass and electrolytes

During a race sweat loss up to 2% of body mass is not associated with impaired performance or electrolytes balance. Losses in excess of 2% can affect the performance and should be compensated by fluid ingestion to avoid hypernatremia (excessive sodium levels in blood). Nevertheless, as we already went through another entry, drinking uniquely water could lead to hyponatremia (low sodium levels).

Runners body mass did not change significantly after the race (weight loss of 0.8kg).  Similarly, electrolyte levels remain unchanged for Na, Cl, K, and Mg, with only a small increase of Ca reported.

Finishing times were correlated with body mass index, but they weren´t with age or training volume.

Haemolysis and skeletal muscle damage

Haemolysis is related with repetitive foot strikes and gastrointestinal bleeding, and it can lead to situations of anaemia.

Skeletal muscle damage is common after a marathon as a result of many microtraumas. It is accompanied by increased levels of certain enzymes in plasma (creatine kinase CK and lactate dehydrogenase LDH), systemic inflammation (high IL-6 levels) and immune system activation (high white blood cells count, or leucocytosis).

Sports anaemia and severity of skeletal muscle damage are related with the distance covered, so they are usually more frequent in ultramarathons as distances increase, and especially in down-hill races (eccentric workload). In the present study they found increased levels of CK and LDH at both times post-race (15 minutes and 24 hours).

Kidney function

Nearly 40% of marathon finishers present some symptoms of rhabdomyolysis. It is a condition in which products of damaged skeletal muscles, such as myoglobin, reach the kidneys with harmful consequences, leading sometimes to kidney failure.

In the present study markers of renal damage (creatinine, blood urea nitrogen and glomerular filtration rate) were elevated in most of the non-elite ultramarathon runners. These levels were still increased in some runners after the 24h of recovery, indicating some degree of sustained renal dysfunction.

 

The conclusions

Results of the study were limited because of the low number of participants, the absence of females, and the lack of information about food and drink intake during the competition and 24h recovery period.

Nevertheless, it was determined that age, muscle mass, climate conditions, type of workload and experience level influenced skeletal muscle damage, and especially kidney function. Most of these are harmless side effects, although in runners with moderate levels of ultramarathon experience and training kidney injuries could take long to heal.

Because of these results, coaches and non-elite athletes should be aware of the risk of acute kidney injury associated with ultramarathon running. Symptoms which could appear during the consequent days are: too little urine, swelling (in legs ankles, and around the eyes), fatigue, shortness of breath, confusion and nauseas, among others.

 

Run healthy, and within your limits.

GERÊS EXTREME MARATHON (01/12/19 – 86)

5/5

Pros: course and landscapes; organization; different distances offered.

Cons: confusing start.

Finish area

This time around it took us long to sit down and write our report of what would become the last marathon of the calendar year. Sometimes there are not enough hours in the day to fit everything we want.

The Gerês Extreme Marathon had been on the to-do list for a while, although other races or plans had prevented our participation. The race takes place in the Peneda-Gêres National Park, the only one in Portugal, and located in its northern edge. It is organised by the Carlos Sá Nature Events, a company specialized in events in natural areas.

With the marathon there are also races of 32k, half marathon, 14k and an extreme mile one day earlier. Distances for every level, and with an ecological approach: every runner has to carry a liquid container to prevent unnecessary waste.

Maybe the most complicated bit is arriving to the Peneda-Gêres area, and the race headquarters in the village of Gêres. 500 kilometres from Madrid and more than 400 from Lisbon, but much closer if coming from Porto or Galicia. The area offers plenty of things to see around and hiking routes.

On arrival on Saturday evening, among intense raining intervals, firstly we pick the runner kit at the local auditorium. After dinner in one of the many restaurants available in Gêres is time to rest. With accommodation in the village, there is no need to get up too early.

Morning appears cloudy, but with no rain and good running conditions. The club from Valladolid, formed by Pepe Turón, Enrique Benito and me, has a few minutes to spare before the start.  Runners of the 32k depart at 8.50, and the marathoners at 9.00, with a bit of confusion as the 14k start is delayed for a bit, and its runners open a path for us to go.

Why is called “extreme” marathon? Looking to the altimetry it offers 1350m of D+ and 1350m of D-, mostly in roads. The course includes 3 ascensions, being especially hard the first one, which goes from 350 to almost 900 metres in over 7 kilometres.

Altimetry 42k

With the marathon of San Sebastian from last week on the legs I take things easily. Not being a typical road marathon takes out the responsibility of pursuing a target finish time. During the long and steep first slope, I go easily. As I get closer to the summit, where is located the first drink station, front runners are already on their way down. During the downhill section I can recover a few places, while also having time to enjoy the views.

View during the race course

The next two uphill sections are also hard, but not as much as the first one. Energy decreases, despite eating bananas in the stations and my gels, but I can keep running even on the steeper sections. Knowing that the last 8 kilometres are downhill is an encouragement as I get to the last lookout point and drinking station. The worst is done. Legs suffer in the way down: the punishment of a faster pace and the continuous braking.

A short detour around the Gêres village that seems to be too long at this stage gets me to the finish line. Net time of 4.31.31, and position 136 out of 218 runners. With a long trip ahead, there is only time for a quick shower before heading back home.

This was marathon number 13 of 2019, to finish the season with the same number than in 2018.

We will be back with new marathons in 2020, when we will try to get to 100 and celebrate the 20th anniversary from our marathon debut. Thanks for reading.

RACE (2016, 134min, Stephen Hopkins)

4/5

Pros: Stephan James´s acting work; filmed in location; admitting the racism present in the USA without demonizing uniquely the German side.

Cons: it could have gone beyond his Olympic days but is clearly focused on Owens´s most brilliant phase; the flirting part.

 

 

We are in front of a biopic of the famous James Cleveland Owens, best known as “Jesse” Owens, going from his early university student days in 1933 to his Olympic successes in Berlin 1936. He is interpreted by Stephan James as Owens, and Jason Sudeikis as his coach, with the participation of Jeremy Irons, Carice van Houten and William Hurt in secondary roles.

Owens is from a humble family and already has a daughter. He knows that studying may be his only chance to get a living, so he moves to Ohio State University, where soon gets under the wings of coach Larry Snyder, himself Olympic in 1924.

With 28 months to go before the Olympics we watch Owens´s life and on the background the possibility of a USA boycott on Berlin, because of its political stand on the Jewish matter. A representative of the USA Olympic Committee, Avery Brundage (Jeremy Irons), visits Berlin to get assurance from the German Committee that there will be no problems with Jewish or black people competing, while visiting the construction works on the Olympic Stadium.

Among the historical figures we have in the movie are Josef Goebbels and Leni Riefensthal on the German side. The first trying to establish the Olympics as a nazi propaganda event, and the second one, as an artist/filmmaker who wants to make the best film possible about the Olympics and its preparation.

In 1935 Owens during the Big Ten meet, wins four events in 45 minutes: the 100 yards, long jump, 200 yards and 225-yard hurdles, breaking the world record in the last three events. He appears as a clear favourite for the following year Olympics.

In a close vote at the end of 1935 the USA Olympic Committee decides to attend the Olympics. But soon before the event Owens feels pressure from the black community to resign from attending to condemn German politics. He finally decides to go anyhow and make his statement by competing. His coach, not allowed to integer the Olympic team, travels to Berlin on his own.

The last third of the movie is in Berlin, where Owens for the first time can share accommodation with their white colleagues. We don’t get to watch all qualification races, but obviously it would slow the movie pace. In the 100 metres final, he wins clearly, getting his first gold medal.

We are shown that Owens is not greeted by Hitler himself, although this scene in the movie may not be exactly true, as in real life Owens assured that he was greeted by Hitler and even had a picture showing it. Nevertheless, it wouldn´t change much Hitler´s image nowadays.

The second gold medal comes in the long jump, after a hard competition with the German Luz Long, who helps him to qualify for the final, after two null jumps. At the end Owens gets the victory after breaking the Olympic record in his third attempt, although he had ensured the gold in his second attempt. Both, Owens and Long do the honour lap together.

His third gold medal comes in the 200 metres, and that was supposed to be his last one, but two members of the 4X100 relay are Jewish, and forced out of the team by Brundage, whom Goebbels blackmails because of his previous business acquaintances. Owens enters in the team as a replacement in the first relay post, winning his 4th gold Olympic medal.

Back in the USA Owens is received by crowds in New York, but still unable to get through the main door to his own tribute, showing us that the big prevailing problems with racism back at home. He was never invited to the White House, nor his achievements get any governmental recognition.

With the film finishing we know of our other characters future. We know that Owens and his rival Long were friends until Long´s death. The consequences of his cordial attitude towards Owens cost him the life, as he was sent to the front during WWII as a punishment for his actions during the Olympics.

Coach Larry Snyder continued training in Ohio State University and was head coach of athletics in the 1960 Rome Olympics. Brundage was chosen as President of the USA Olympic Committee in 1952, a position he held for more than 20 years until his death.

 

A recommendable film, as there are not many historical films about athletics, and focused on one of its undoubtable legends.13

SPORTSWOMEN AND PELVIC FLOOR IMPORTANCE

Photo by Matt Lee in Unsplash

The pelvic floor is a structure composed of muscles and connective tissue, underneath the pelvis, and whose function is separate the pelvic cavity and the perineal region. It is present in males and females, although in the latest is larger because it also contains the birth canal. Its main function is supporting organs such as the bladder, intestines and uterus (in women), and in the maintenance of the continence and intra-abdominal pressure.

When there is a dysfunction of the pelvic floor some consequences are: urinary incontinence, pelvic organ prolapse (when an organ slide from its position into the vagina) or sexual dysfunctions.

Physical exercise carries many health benefits, but it is also related with some pelvic floor problems in female athletes, the most common one being urinary incontinence.

Many young women have no knowledge about pelvic floor function, and how sports practice may be related with some of its associated problems. Sports practice increases intra-abdominal pressure, especially in high impact disciplines.

There are two opposing theories relating exercise and pelvic floor dysfunctions:

  • Female athletes have stronger pelvic floor muscles.
  • Female athletes may overload, stretch and weaken their pelvic floor muscles.

If the pelvic floor musculature is weaker than the surrounding muscles, it may not be able to contract simultaneously with them, causing urinary losses, especially in conditions of physical exertion. Nevertheless, pelvic floor muscles training has been related with an improvement in some symptoms, as muscular strengthening allows a better blood supply and nerve activity in the area.

The National Institute of Health and Care Excellence of the United States recommends women with incontinence to perform at least 8 pelvic floor contractions, 3 times per day. There are different exercising options, such long squeezes or fast short squeezes, with fully relaxation between them.

Women who carried out pelvic floor training were 17 times more likely to report an improvement of their symptoms or total cure, so it should be the first treatment of choice for any type of urinary incontinence.

With the increase of women practicing sports, educational campaigns should be in place to provide enough information and remove the “shame” and secrecy of these situations. It would encourage them to get treatment and solve the problem.

SAN SEBASTIAN MARATHON (24/11/19 – 85)

Panoramic view of La Concha
5/5

Pros: flat course; spotless organization; well provided aid stations; free buses to/from start/finish.

Cons: maybe more stands in the running expo.

Introductory panel

With the dates of some marathons changing so much lately it is good to know that San Sebastian has been stable at the end of November for many years. Valencia moved from February to November, and nowadays to early December. Gran Canaria has decided to move its 2020 edition from its usual January slot to sometime in November, trying to get more runners, although I run in 2018 and there were a lot of foreign athletes. Its slot in a month lacking marathons has been luckily filled by the Almagro marathon (moving also from its June slot). And Pamplona has gone even further, and recently cancelled the marathon distance for 2020 altogether.

Marathon 85 was supposed to be Puerto Varas, in Chile, but it was cancelled as a result of the widespread social unrest in the country. Back in Spain San Sebastian was waiting for a fourth time (and third in a row).

As usual I arrive on Saturday and go straight to the running expo in the velodrome of Anoeta to collect my bib number, and this time around the t-shirt, that I forgot to pick up last year. Unlike other editions it is very quiet, with no many runners or stands around. Maybe runners collected the numbers earlier or in the alternative locations provided on previous days.

Free from duties, time to eat some pintxos in the central tabernas with my friend Gonzalo, who also is running again the marathon. Satisfied I walk to my accommodation. With strong wind and now also raining it doesn´t look very inviting for race day.

This time I stay in the local hostel, not exactly in the city centre, but offering basic and clean lodging on a budget. With so many visitors for the races, prices hike up considerably during the weekend. Additionally, the organization bus will stop at the front door at 7.50 on Sunday to get to the start area.

As weather doesn´t accompany much, I spend the evening resting. I get up at 6.00 and get my breakfast with plenty of time before the race, scheduled at 9.00, as it is the half marathon. It keeps raining during the short bus trip to Anoeta, where I leave my luggage just around the clock, trying to stay warm for as long as possible.

The course is the traditional from other years, with 2-laps for the marathon and only one for the half-marathon and following the seaside in many sections. After so much rain, it stops exactly as races start. Running conditions become ideal with cloudy sky and a temperature of 10-11°C.

The first kilometres I navigate among runners, but things get easier soon. I am close to the 3.30 group, although not fast enough to catch them, while keeping my distance from the 3.45 one. Aid stations are frequent and well supplied with isotonic drink, water and nuts, and further in the race also bananas and energy gels.

I cross the half marathon in 1.46.32. Things look good, as even with my usual delay in the second half I could improve my results in the last 2 editions (3.46.00 and 3.45.02). Fresher than last years, with less marathons in previous weeks, I can keep a good pace, surpassing runners as I get into the last kilometres. I finish the race in 3.38.42, for the 12th marathon of the year, getting also my season best.

No much rest as next week is time to run again. Portugal awaits with its Gerês Extreme Marathon, in the Peneda- Gerês National Park, so-called the world´s toughest road marathon. Follow us and find our report here soon.

MARATHON OLYMPIC CHAMPIONS (XIV) – Rome 1960: ABEBE BIKILA (1932-1973)

Bikila´s final attack on Rhadi in Rome

“I wanted the world to know that my country Ethiopia has always won with determination and heroism.” Abebe Bikila

Rome has been rewarded the Olympic Games of 1908, but an eruption of the Vesuvius in 1906 obligated the Italian capital to skip the event in favour of London. Its time would come again, when it was selected to host the Olympics of 1960, taking them back to the very same place where they had been forbidden by Emperor Theodosius in 393.

The Games were very well received in Rome, with unprecedented crowds, being the first to be broadcasted. A young boxer called Cassius Clay won a gold Olympic medal, and sadly there was the first known Olympic death for using performing enhancing drugs (the Danish Enemark Jensen).

Abebe Bikila was born in Jatta, Ethiopia, in 1932 on the same day Argentinian Juan Carlos Zabala won the Los Angeles Olympics marathon. Of humble origin he worked very young herding cattle. On a trip to the capital Addis Ababa when he was 19, was impressed with the Imperial Guard and enlisted.

Naturally gifted he started soon competing with the armed forces team in the 5000 and 10000 meters, running his first marathon only in 1959. Under Finnish coach Onni Niskanen he won the marathon trial one month before the Olympic Games. His time of 2.21.23 at Addis Ababa´s altitude (2400m) was better than the one achieved by defending Olympic champion Alain Mimoun at sea level (2.25.00).

The Olympic marathon was scheduled for September 10. The triangular course didn´t start nor finish in the Olympic stadium, but in Campidoglio and the Arch of Constantine respectively, just in the city centre. Expecting warm weather, the start was delayed until 17.30 for the 59 runners present. Hundreds of torchbearers on both sides of the road were ready to provide illumination when dark.

A large leading group of athletes was still together by the 10k (31.07). Everyone seemed cautious because it was still warm and the difficulty of the course, that forced them to dash around monuments and plazas.

By the 20k (1.02.39) a barefoot Ethiopian, Bikila, was in front accompanied by Moroccan Rhadi ben Abdesselem, totally unknow besides his participation in the 10000 metres a couple days earlier and debuting in the marathon. Half a minute behind was Belgian champion Aurele Vandendriessche.

The front African duo continued increasing distance with their pursuers. At 30k (1.34.29) they had opened a 2-minutes gap over Barry Magee from New Zealand, and the soviet and world-record holder Sergey Popov.

At 40k (2.08.33), and already heading towards the finish line, Magee´s pace had brought him only 86 seconds behind the front runners. Behind him soviet marathon champion Konstantin Vorobiev had overtaken his comrade Popov.

It was time to fight for victory, as the race was nearing its conclusion. First Rhadi tried to move away from Bikila but failed. When reaching the Obelisco di Axum, in Piazza di Porta Capena, that has been brought from Ethiopia by the Italians in 1936, Bikila attacked. He knew that it was only 500 metres from the finish line, and Rhadi was unable to fight back. The gold medal was for Bikila in 2.15.16, improving the world record of Popov by just 1 second. 25 seconds behind entered Rhadi, for Morocco, with New Zealand´s Maggie getting the bronze medal.

The quality of the race was impressive, as 15 finishers managed to complete the marathon under Zátopek´s record of 2.23.03 established in Helsinki only four years earlier. African countries had demonstrated for the first time their quality in the marathon, allocating 4 of the top-8 finishers and changing the marathon trend that had gone until then.

As for Bikila he became instantly a hero in Ethiopia. His history was far from over as we will see in our next entry, dedicated to the Olympic Games of Tokyo in 1964, where he became the first athlete to revalidate his marathon Olympic title. But that is another story.

SUPPLEMENTS TO REDUCE EXERCISE-INDUCED MUSCLE DAMAGE

Exercise-induced muscle damage occurs after unaccustomed exercise. It was firstly described in 1902 as a delayed muscle soreness being already suggested that it was caused by microtears in the muscles.

Nowadays it is accepted that exercise-induced damage results in pain, soreness, inflammation and reduced muscle function, often accompanied by an increase in intramuscular enzymes levels and inflammation markers. All these effects are annoying and may potentially affect training levels and athletic performance. It is a temporary damage, but when time is limited it can be useful to reduce recovery time to a minimum.

There a lot of techniques used for recovery (massage, cryotherapy, stretching…) with varied results, but there is also the possibility of counteracting muscle damage with specific foods or supplements, that we will cover in this entrance.

 

Fruits

Blackcurrants and cherries are rich in anthocyanins, natural pigments with potent antioxidant and anti-inflammatory properties, helpful in reducing symptoms of muscle damage.

Pineapple is rich in bromelain, with anti-inflammatory properties. Its supplementation improves muscle function, reduces soreness and increase pain threshold.

Pomegranate juice is rich in ellagitannins, a polyphenol with antioxidant and anti-inflammatory properties. Significative reductions in soreness were seen with 15 days of 500mL consumption in resistance-trained subjects.

Watermelon juice also showed improvements in soreness levels. It is rich in L-citrulline, with antioxidant properties and precursor of nitric oxide, key factor in vessels vasodilation.

 

Plants and herbs

We already dedicated one of our entries to beetroot juice. You can find it here. Briefly it is rich in dietary nitrates and betalains, with antioxidant and anti-inflammatory properties, and its consumption is linked to a faster recovery time between exercise bouts.

Green tea is known for being rich in polyphenols, with potent antioxidant effects. Results have been contradictory. Consumption for 13 weeks prior to downhill running (40min at 65% VO2max) decreased soreness 48h after exercise, although other studies didn´t show any effect.

Other spices and less know herbs also showed promising results. Among them we could talk about curcumin (derived from the spice turmeric) that ameliorates muscle damage, ginger, for faster recovery, and ginseng, that reduced markers of muscle damage. Nevertheless, more studies are needed for all these compounds.

 

Amino Acid and Protein Supplements

Branched chain amino acids, or BCAA, are quite popular. Its supplementation at levels of at least 200mg/kg/day for a minimum of 10 days could be effective in reducing moderate muscle damage.

Creatine is used as energy substrate, but also has antioxidant and anti-inflammatory effects. Its supplementation had mixed results, although it shows some promise in attenuating damage induced by endurance or sprint exercise.

β-hydroxy-β-methylbutyrate, or HMB, may improve biochemical measures of exercise induced muscle damage by increasing protein synthesis and decreasing muscle protein breakdown. Supplementation ranged from 0.3 to 3 g/day for a period between 2 and 6 weeks prior to effort.

L-glutamine has shown in several publications that may improve muscle function and reduce biomarkers of damage. It has been suggested to improve immune function and replenish plasma levels of glutamine, that decrease during prolonged exercise.

Taurine has also antioxidant effects and has been suggested to regulate calcium homeostasis in skeletal and cardiac muscle tissues, that could make it useful for attenuating muscle damage.

 

Other compounds

Vitamins C and E supplementation offered mixed results, while vitamin D was the subject of a recent entry where we explained its effects extensively.

Other promising results have been shown for methylsulfonylmethane, or MSM, and caffeine. Both of these compounds had already their own entry in our blog here and here respectively.

Specialized waters are also becoming a focus of interest recently. Deep ocean mineral water consumption after workout improved markers of muscular damage after a single bout of fatiguing treadmill exercise (40% VO2max until 3% body mass lost). These results were confirmed in later studies and using bedrock mineral water too.

As you can see, and we have gone only through some of them, there are many compounds with potentially promising results in delaying/avoiding effects on exercise-induced muscle damage, although more studies are necessary to completely understand their effects.
