Much of the previous research into understanding fatigue during prolonged cycling has
found that cycling performance may be limited by numerous physiological, biomechanical,
environmental, mechanical and psychological factors. From over 2000 manuscripts …

The original central fatigue hypothesis suggested that an exercise-induced increase in
extracellular serotonin concentrations in several brain regions contributed to the
development of fatigue during prolonged exercise. Serotonin has been linked to fatigue …

The aim of the present study was to examine the regulation of exercise intensity in hot
environments when exercise is performed at a predetermined, fixed subjective rating of
perceived exertion (RPE). Eight cyclists performed cycling trials at 15° C (COOL), 25° C …

To assess the effect of cold water immersion and active recovery on thermoregulation and
repeat cycling performance in the heat, ten well-trained male cyclists completed five trials,
each separated by one week. Each trial consisted of a 30-min exercise task, one of five 15 …

The present study independently evaluated temperature and thermal perception as
controllers of thermoregulatory behavior in humans. This was accomplished using a self-
paced exercise and heat stress model in which twelve physically active male subjects …

The human capacity to perform prolonged exercise is impaired in hot environments. To
address this issue, a number of studies have investigated behavioral aspects of
thermoregulation that are recognized as important factors in determining performance. In …

The ratings of perceived exertion are a widely accepted measure of quantifying, monitoring
and regulating exercise intensity. A critical review of the perceived exertion literature since
2000 provides a useful insight into the concepts and themes that have featured prominently …

The aim of this study was to characterize several of the thermal input (s) that influence
thermo-behavior in humans. Eight male subjects completed two trials in which they were
free to initiate an exit from a hot chamber (45° C) to a cold chamber (10° C; H→ C) or from a …

The present study investigated whether face cooling reduced both the perceived exertion
(RPE) and prolactin (PRL) release during hyperthermic exercise. Ten, non‐heat‐acclimated
males (23±2 years; maximal oxygen consumption, 56±7 ml kg–1 min–1 [mean±sd]) …

Purpose: This study was conducted to examine the pacing strategies used under varying
conditions during the cycle phase of an Ironman triathlon. Methods: The bicycles of six well-
trained male triathletes were equipped with SRM power meters set to record power output …
