Sports Science Monthly – July 2020

Every month we take a deep dive into the latest research in sports science. In the July edition we start off by taking a look at some lessons coaches can learn from medicine in dealing with COVID-19. In addition, we break down the latest research on hamstring strength asymmetry, resilience, willpower, nitrate supplementation and more. Read more

Optimal energy intake for performance health

As the performance health series continues, let’s stop to catch our breath, and briefly review where we’ve gotten to. So far, we’ve seen that the risk of injury and illness is complex and multifactorial, with a number of different models helping us to better understand how we might get injured. We’ve discussed the influence of “load”, a broad term which can include physiological, psychological, and lifestyle-related factors. We looked closely at illness and immune function and how psychological and lifestyle-related factors such as poor sleep and anxiety can increase the risk of both illness and injury. Similarly, inadequate nutrition, especially inadequate energy intake, is also a significant risk factor. This article will continue with this last point and take a deeper look at nutrition and energy intake. Read more

The surprising performance enhancing effects of bacteria

At the 2008 Olympic Games, Taiwanese weightlifter Chen Wei-Ling won the Bronze medal in the 48-kilogram category, snatching 84 kilograms, and clean and jerking 112 kilograms. Following the disqualification of the original gold and silver medalists, she was later awarded the gold medal for her performance. A decade later she is making headlines for the bacteria in her gut.

The definitive guide to what we do and do not know about caffeine and performance

Caffeine is a performance enhancing drug. If you’ve been following my articles over the last couple of years, you’ll no doubt be aware of that, because I write about it a lot. Athletes, of course, know that caffeine has the potential to enhance their performance, which is why many of them consume it prior to training and competition. Additionally, the World Anti-Doping Agency (WADA) know that caffeine is a performance enhancing drug and are, rightly, concerned about the abuse of caffeine in sport. Read more

Sports Science Monthly – April 2019

Every month we take a deep dive into the latest research in sports science. In the April Sports Science Monthly we start off by looking at a new framework for evaluating research. Then we focus on new findings about specific topics like gluten free diets for athletes, the role of testosterone in female performance, sports nutrition, the speed gene, and more. Read more

Sports Science Monthly – December 2018

Lots of new topics in the December edition of Sports Science Monthly. Our first study looks at the role of genetics in endurance programming. We also look at research on whether athletes eat enough, monitoring acute:chronic training loads, biomarkers, acceleration performance, and some interesting new research on tactical periodization.

Sports Science Monthly – October 2018

There are lots of hot topics covered in the October edition of Sports Science Monthly. We start off by looking at the transfer of different types of strength to sprinting, then see how monitoring can be taken best from theory to practice, before diving into density of high speed training, adductor strengthening, dehydration, transcranial direct current stimulation, and more.

Sports Science Monthly – September 2018

Welcome back to another edition of Sports Science Monthly. This month, we take a closer look at the timing of injury prevention training, mental fatigue, antioxidants, max testing, agility, chocolate milk, and several other topics. Read more

Sports Science Monthly – August 2018

Welcome back to another edition of Sports Science Monthly. This month, we take a closer look at periodizing some different aspects of training, sleep as a measurement for overtraining, building resilience, supplements, and several other topics. Read more

Individualizing pre-competition caffeine use

This month’s theme on HMMR Media is around the personalization and individualization of performance. Typically, this focuses on the physical side, but at the start of this month I wrote about how a focus on differences in stress tolerance—a largely psychological aspect—might guide individualized training a bit more. But there is another area where we can turn our attention; that of ergogenic aids such as caffeine. Towards the end of last year I co-authored a paper with John Kiely on factors that might impact the individual response to caffeine intake in athletes. In this article, I want to expand on that topic, and discuss how athletes and coaches might use this information in a real-world setting. Read more
