Cryotherapy and recovery

Cryotherapy and recovery

Cryotherapy has gained momentum over the past 10-15 years as a recovery strategy in elite athletes. It purports to minimize muscle damage following exercise, reduce symptoms of DOMS and speed up the healing process. So how effective is the method? In a study by Sellwood et al. (2007), 40 males were randomized into 3 *(…)

Fitness, body anthropometry and athletic performance

Fitness, body anthropometry and athletic performance

Bigger, faster, stronger: a profile of the modern professional athlete. One strength and conditioning component that’s been put on the back burner these past few years is maximum aerobic power.  Recently, the publication of the Brazilian male judo national team anthropokinetic data demonstrated the importance of maximum aerobic power on judo-specific performance. Seven different weight-classes of athletes(…)

Overtraining: a case study

Overtraining: a case study

Overtraining can occur following years of overloading without adequate recovery. Elite level runners and cyclists follow training regimes which are highly demanding but absolutely necessary to significantly improve performance. For example, there is very little longitudinal data to show improvements in running economy. Studies by Paavolainen et al. (1999) and Millet et al. (2002) where(…)

Circadian rhythm: jet-lag

Circadian rhythm: jet-lag

If you are a professional athlete, the unfortunately reality of life is that you will have to travel a lot across multiple time-zones to compete. (Tennis players have it worst!) This induces a significant challenge to the body’s circadian rhythm. Are there strategies that can be successfully employed to minimize the effect of jet-lag? While(…)

The metabolic cost of skipping

The metabolic cost of skipping

Skipping has made a huge comeback as a mode of physical activity in recent years. While there is not much data highlighting the benefits of skipping, some early studies from the 80’s are insightful as to the effect of skipping on whole-body metabolism. Town et al. (1980) demonstrated the effect of different skipping rates in(…)

Circadian rhythm and exercise: effect on strength, power and endurance

Circadian rhythm and exercise: effect on strength, power and endurance

Does it matter at what time of the day we exercise? The science says that we perform better in the evening than in the morning. This should have implications for the timing of athlete training and competition scheduling. Maximal voluntary strength of the quadriceps and hamstrings were tested in a group of females at 06:00(…)
