Daily bar of chocolate boosts performance

March 15, 2021 | News | No Comments

Dark chocolate has similar performance benefits to beetroot and can give you an extra edge in your fitness training scientists from Kingston University have discovered.

“Beetroot juice is rich in nitrates, which are converted to nitric oxide in the body. This dilates blood vessels and reduces oxygen consumption – allowing athletes to go further for longer,” explained postgraduate research student Rishikesh Kankesh Patel

The Kingston University team wanted to find out whether dark chocolate could provide a similar boost, as it contains a substance called epicatechin – a type of flavanol found in the cacao bean, that also increases nitric oxide production in the body.

After undergoing initial fitness tests to establish a baseline for comparison, a group of nine amateur cyclists were then split into two groups. The first group was asked to replace one of its normal daily snacks with 40g of a dark chocolate known to be rich in flavanols for a fortnight, while the other participants substituted 40g of white chocolate for one of their daily snacks as a control.

The effects of the athletes’ daily chocolate consumption were then measured in a series of cycling exercise tests in the sports performance laboratory. The cyclists’ heart rates and oxygen consumption levels were measured during moderate exercise and in time trials. After a seven-day interval, the groups then switched chocolate types and the two-week trial and subsequent exercise tests were repeated.

The study, which has now been published in the Journal of the International Society of Sports Nutrition, found that after eating dark chocolate, the riders used less oxygen when cycling at a moderate pace and also covered more distance in a two-minute flat-out time trial.

Mr Patel said the results opened the door for more research which could eventually lead to dark chocolate becoming a staple part of endurance athletes’ diets.

“Both dark chocolate and beetroot juice are known to increase nitric oxide, which is the major mechanism we believe is behind these results,” Patel said. “We found that people could effectively exercise for longer after eating dark chocolate –something that’s not been established before in this way.”

“We want to see whether the boost in performance is a short term effect – you eat a bar and within a day it works – or whether it takes slightly longer, which is what the initial research is showing,” Mr Patel said. “We are also investigating the optimal level of flavanols. At the moment there is not a lot of consistency in flavanol levels in commercially-available chocolate. Once we’ve found the optimal chocolate dose and duration, we’ll compare its effects to those of beetroot juice, and also test the influence of combining consumption of both, as they produce an increase in nitric oxide in slightly different ways.”

Sport analysis lecturer James Brouner, who is an ultra-distance runner in his spare time, said that the research suggested dark chocolate could offer particular benefits to endurance athletes.

“From a performance perspective, making an athlete more efficient can have major advantages in long duration steady-state exercise,” he said. “With so many athletes consuming beetroot juice to achieve this gain but complaining of the palatability, dark chocolate could have a similar effect but with the additional benefit of tasting good too.

“When performing endurance-based activity, being as economical as possible in energy provision is key to enhancing your performance. From our results, the consumption of dark chocolate has altered the participants’ response to the activity and therefore could enhance their endurance performance.”

Improving strength and stamina

Some of the world’s most acclaimed nutritionists, including Louise Burke of the Australian Institute of Sport and Team Sky’s James Morton, have joined forces to formulate sports-nutrition strategies for training in Olympic year.

The authors also say there’s credible evidence that the following ergogenic aids improve strength and stamina: caffeine, creatine, sodium bicarbonate, beta-alanine and nitrates. The team highlights the emergence of vitamin D, too, showing that the science suggesting that vitamin D encourages muscle regeneration does add up. 

Finally, the team looks at compounds such as epicatechin, nicotinamide riboside, resveratrol, beta-hydroxy beta-methylbutyrate, phosphatidic acid and ursolic acid that may also promote skeletal muscle adaptations to endurance and strength training, though studies of these compounds have largely been limited to rats.

Benefits of organic meet

It’s official: organic meat is better for you than non-organic. A team of 25 researchers undertook a meta-analysis examining how nutritional content varied between organic and non-organic red meats. Though the evidence wasn’t strong enough to verify differences in antioxidant and mineral content, it did show that organic meat contains 47% more omega-3 than the non-organic alternative. This is good news for triathletes, because this polyunsaturated fatty acid has been proven to improve recovery, reduce muscle soreness after exercise and even increase fat metabolism.

Beetroot

First it was claimed that beetroot (rich in nitrates) sent endurance through the roof, then it was labelled a memory enhancer. Now nitrates have been shown to improve neuromuscular function.
A study from Ohio, USA, assessed isometric and dynamic contractions in 14 resistance-trained athletes before and after three days of nitrate supplementation. The nitrate hit resulted in higher mean peak electromyography amplitudes: electrical signals travelled that bit faster. So nitrate supplementation could enhance muscle activation, leading to greater power and speed.

WTS Cape Town: Who’s competing

March 15, 2021 | News | No Comments

WTS Gold Coast victor and current leader of the WTS rankings, Britain’s Helen Jenkins, won’t be competing but her Rio team mates Non Stanford and Vicky Holland will be there, along with Jodie Stimpson, whose disappointing run in Australia ruled her out of a place on the British team. Holland won her first WTS race in Cape Town last year, and Stanford has a proven winning record at the sprint distance.

Last year Holland finished ahead of Katie Zaferes (USA) and Olympic Champion, Nicola Spirig (SUI) in a thrilling tight finish exactly a year ago.

She said: “This was the race that gave me the confidence to believe I could aim for the top of the podium, it was quite a break through last year, so it’s great to be back. This year it’s a sprint rather than Olympic distance, and my first race of the season, so it’s quite different, but I’m looking forward to getting out there.”

 The line up also includes Flora Duffy (BER), second on the WTS rankings thanks to her two fourth-place WTS finishes in Abu Dhabi and Gold Coast, who will be hopeful of a podium finish.

As one of the best cyclists in the field, in Gold Coast Duffy successfully led a breakaway of three away from the lead pack that allowed a healthy advantage going into the second transition zone. South Africa is a familiar setting for Duffy, as she trains down the road in Stellenbosch for much of the year, meaning Missing from the line up is Gwen Jorgensen

Full women’s start list

Meanwhile the question in the men’s race is can Mario Mola keep up his unbeatable run and make it three in a row at WTS Cape Town in South Africa this weekend? The South African city is offering up the first sprint-distance course of the season as the men vie for more valuable Olympic qualification points as they tackle a one-lap swim, five-lap bike and two-lap run.

Joining Mola is fellow Spaniard Fernando Alarza who joined Mola on the Gold Coast podium by capturing the silver in the final lap of the run. He also just missed the podium in Abu Dhabi with his fourth-place finish.

Hoping to beat Mola will be Britain’s Jonathan Brownlee, however he won’t be joined by his brother Alistair as still has not recovered from a virus and unfortunately won’t be able to defend his 2015 victory in Cape Town. Jonny will be joined by fellow Brit Adam Bowden.

Non Stanford and Vicky Holland secure spots for Rio

Although heavy storms greeted the athletes on their arrival into Cape Town, conditions were perfect for the race itself with temperatures of 20c and light winds. After her devastation at not been selected for the Olympic Games, 2014 WTS Cape Town winner Jodie Stimpson was racing purely to bolster her hopes of a strong position in the ITU series itself. Fellow Brits Vicky Holland, who won in Cape Town last year, and Non Stanford were looking to send a message to their opponents ahead of Rio having already qualified. The winner of WTS Gold Coast Helen Jenkins opted out of this race, as did current world champion Gwen Jorgensen.  

As the athletes dived off the pontoon, Bermudan Flora Duffy and Carolina Routier quickly broke away from the pack, and Duffy broke away again to exit the water in a rapid 8min 55secs. Routier was unable to ride out with Duffy, who rode off solo and established almost a 30sec lead. 

The rest of the ride followed the same pattern, with the chase pack not closing up any of the gap until the final 2km of the bike. Going out onto the run course 6secs in the lead, Duffy was quickly reigned in by four athletes, made up of all three Brit girls of Stimpson, Stanford and Holland as well as Anne Haug of Germany. 

It then became a case of how long Duffy could hold on, having exerted herself more on the bike and not possessing the run speed of the three Brits. It was now looking like a potential 1-2-3 for the British athletes, with Haug looking to put a spanner in the works. 

However it wasn’t so clear cut, as surprisingly Vicky Holland dropped off into 5th with Duffy holding 4th place going into the final 2km of the run. Non Stanford began to show her return to full fitness is nearly complete, and began to put the hammer down. Haug and Stimpson followed her every move, whilst Kirsten Kasper (USA) overtook Holland to move into 5th place. Stimpson then consolidated 2nd position, with Haug fading.

Stanford continued to pull clear and broke the tape in 59:49, whilst Stimpson held on for 2nd place and finished 7secs back. Flora Duffy capped off a remarkable performance by overtaking Haug, claiming her first podium this year after 4th place in the previous two rounds of the series.

It was Stanford’s first race of the WTS Series this year, and she expressed surprise at her victory in an interview with ITU Triathlon: “I’m not in my ideal race shape so came here to see how I’d get on, so it’s great to take the win. There’s more to come yet which is really exciting!” 

Despite the disappointment of missing out on a place in the British Olympic squad, Stimpson showed immense mental strength to finish in 2nd place. She said: “I want to thank my coaches for putting up with me the last couple of weeks, as I haven’t been the most pleasant person to be around! But I will train hard and concentrate on this year’s series and try to finish as high up as I can.”

Fernando Alarza captured his first World Triathlon Series victory in Cape Town today, with pre-race favourite Mario Mola of Spain, looking to claim a 3rd straight WTS victory, unable to catch up after failing to get in the lead bike group.

With Alistair Brownlee sitting out due to illness, it was down to brother Jonny to lead the British contingent. Fellow Brit Adam Bowden was also racing, looking to impress selectors with an outside chance of gaining a place on the GB Olympic team. Richard Murray was also missing with an injury, as was Javier Gomez – otherwise it was a stacked field, with Mario Mola being the one to beat due to his blistering run speed. 

Off the pontoon in the sprint-distance race it was one long line for the duration of the 750m swim, with almost no breaks whatsoever in the 64-strong field. It was business as usual for super-swimmer Richard Varga (SVK), who exited the water in 8mins 54secs, followed closely by Henri Schoeman (RSA) and Jonny Brownlee. 

Mario Mola came out of the swim almost 30 secs down, and found himself in the chase group on the bike. The front pack included all those tipped for potential podium places barring Mola, with Brownlee pushing the pace early on. The chase group never managed to claw back more than 6 secs over the whole 20km bike leg, and it was Brownlee, Fernando Alarza (ESP), Dorian Coninx (FRA) and Shoeman who came into T2 first. 

Jonny Brownlee comes into T2 well positioned before going on to take 2nd place, with eventual winner Alarza going neck-and-neck. Image credit: ITU

The front group slimmed down to three after the first 1km of the run, with Brownlee, Alarza and Coninx breaking away. After 3km it was looking like Mola had left himself too much to do, 20secs back from the leaders but running blisteringly fast and under 14min pace for 5km. 

With under 1km to go Coninx finally dropped off the pace and Alarza put the hammer down on Brownlee, and continued all the way to hold on a massive first WTS victory, surely securing a spot on Spain’s Olympic team. Mola finished in 4th, putting in the fastest run split of the day (14:24) but ultimately unable to secure a place on the podium. Adam Bowden put in a solid performance to finish in 16th place, with an impressive sub 15min 5km run.

Speaking to ITU Triathlon, Jonny Brownlee commented: “I’ve felt pretty bad after what happened at Gold Coast, I’m just happy not to finish on a stretcher! But from where I was two weeks ago it’s a decent result, I worked really hard on the bike and hopefully I can turn it round in the races leading up to the Olympics.”

Alarza said: “I’m really happy today, I think now I’ve finally earned my spot for Rio and I can concentrate on training hard for that now.”

The course was a sprint distance (750m swim, 20km run, 5k run) and the two golds were won by George Peasgood (PT4) and Andy Lewis (PT 2), while the silvers were won by Joe Townsend and Clare Cunningham (PT4)won silver, collectinvaluable ranking points that will help qualify slots for the Rio 2016 Paralympic Games. Unfortunately, Lauren Steadman was unable to start due to illness.

Peasgood used his swim and bike strength to set up a big lead, which he held on to during the run, and won by a comfortable margin of well over a minute from Alexander Yalchik of Russia, while in his section Andy Lewis was an emphatic winner, being the fastest swimmer, cyclist and runner on the day.

Joe Townsend finished second behind five-time ITU world champion, Bill Chaffey of Australia in the PT1 event. Afghanistan veteran, Townsend was the fastest over the bike and run sections, but Chaffey’s superior swim set up his victory. After a strong start Clare Cunningham she lost time on the bike, but ran well to secure silver.

The next round of the ITU World Paratriathlon Event Series will coincide with the ITU World Triathlon Series event in Yokohama, 14-15 May.

The difference between elite athletes and the ‘almost’ greats is their internal drive to overcome adversity a new study has discovered.

Advertisement

The research found elite athletes approached training with a “never satisfied” attitude, whereas ‘almosts’ might avoid challenging training exercises, while following an injury or a failure to perform, high performers were determined to get back to their sports, stronger than ever. Low achievers, on the other hand, often expressed surprise at their failures, telling how they lost enthusiasm after such incidents.

Despite these differences in the athletes’ attitudes, there was surprisingly little variation in the nature or number of the challenges themselves. All had roughly comparable traumatic incidents during their careers. More than the challenges themselves, the differences came down to how the athletes reacted to these obstacles and the champions’ positive, “learn from it” attitudes.

“We’ve found that there are universal psychological characteristics amongst those who are aspiring to get to the top,” says lead author Professor Dave Collins from the Institute of Coaching and Performance at the University of Central Lancashire. “We have a good idea of what makes people excellent and how we can help them reach peak performance.”

Through interviews Collins and his team sought to find distinguishing characteristics between the best of the best, the good, and those that didn’t quite make the cut. For each participant, they collected information about career trajectory, perceived challenges and the participant’s reactions to such obstacles. Interview questions also explored participants’ commitment to their sports and their interactions with coaches and families.

“From our research, we’re assembling a set of rules to guide what a coach should be doing and what skills an athlete should end up with,” says Collins. “Furthermore, these characteristics hold true for other fields as well, from sports to music to any environment.”

While challenge may be integral on the path to success, this research suggests that challenge is not sufficient in itself. An aspiring athlete’s attitude towards challenge is what most distinguishes the champions from the rest.

A single minute of very intense exercise produces health benefits similar to longer, traditional endurance training researchers have found

Advertisement

 “This is a very time-efficient workout strategy,” says lead author Martin Gibala, a professor of kinesiology at McMaster University in Canada. “Brief bursts of intense exercise are remarkably effective.”

The team of scientists set out to determine how sprint interval training (SIT) compared to moderate-intensity continuous training (MICT). They examined key health indicators including cardiorespiratory fitness and insulin sensitivity, a measure of how the body regulates blood sugar.

A total of 27 sedentary men were recruited and assigned to perform three weekly sessions of either intense or moderate training for 12 weeks, or to a control group that did not exercise).

The McMaster team has previously shown that the SIT protocol, which involved three 20-second ‘all-out’ cycle sprints, was effective for boosting fitness. The workout totalled just 10 minutes, including a 2-minute warm-up and 3-minute cool down, and two minutes of easy cycling for recovery between the hard sprints.

The new study compared the SIT protocol with a group who performed 45 minutes of continuous cycling at a moderate pace, plus the same warm-up and cool down. After 12 weeks of training, the results were remarkably similar, even though the MICT protocol involved five times as much exercise and a five-fold greater time commitment.

 “Our study shows that an interval-based approach can be more efficient — you can get health and fitness benefits comparable to the traditional approach, in less time.”
