Stephen S. Cheung, Ph.D. - Adapting to Training and Competing in the Heat (esitys englanniksi)

Many sports are conducted in warm to extremely hot temperatures. Hyperthermia can lead to performance impairment across multiple physiological systems, from cardiovascular through to neuromuscular and neurohumoral. Heat stress may also alter an athlete’s pre-planned performance template and pacing strategy, along with their overall perception of exercise and voluntary exercise capacity. Of the many potential countermeasures for reducing heat stress during exercise, progressive adaptation to higher heat loads via laboratory acclimation or natural exposure (acclimatization) provides the largest magnitude for improvement that is also the most durable and sustained. Heat adaptation may include reductions in resting core temperature and heart rates, increased resting plasma volume, and habituation resulting in reduced thermal discomfort. In addition, a higher sweat rate – especially from a lower core temperature threshold for sweating onset – results in a greater evaporative heat loss capacity. These responses may each have different thresholds of stimulus duration and intensity for maximal effect. Furthermore, each may have its own timeline for onset and decay. Regardless, heat adaptation appears to be a highly effective way to improve both exercise capacity and performance in the heat. The magnitude and timeline of improvement may depend on both total time spent in hyperthermia, the ambient conditions, and the method of heat Adapting to Training and Competing in the Heatexposure. This talk will also survey the logistical and training modifications that may be required to optimize response. It will also explore the use of pre-cooling measures to reduce heat strain prior to exercise.

Stephen Cheung – Introduction

Stephen Cheung, Ph.D. is a full Professor and Canada Research Chair in the Department of Kinesiology at Brock University in St. Catharines, Canada. His Environmental Ergonomics Lab (EEL) focuses on the effects of environmental stress (e.g., hot and cold temperatures, high altitude, cold water) on human physiology and performance. As an example, his work has demonstrated the direct role of high core temperatures in reducing the ability of the brain to recruit and activate muscles. At the same time, he and his group use this knowledge to develop better cooling strategies for athletes and workers in hot conditions.
In addition to his scientific research into the effects of environmental stress on human physiology and performance, Stephen has been heavily involved in the science of cycling. Since 2002, he has been the Sports Science and Training Editor for the popular cycling website www.pezcyclingnews.com. Stephen co-authored “Cutting-Edge Cycling” with Hunter Allen in 2012, and is currently co-editing the book “Cycling Science” with Mikel Zabala from the Movistar ProCycling Team. Stephen has also worked on research and product development within the cycling industry, including clothing testing in thermal extremes and the analysis of cycling biomechanics using power meters. Stephen has competed in cycling on the road, cyclocross, and mountain bike since 1986.
