Effects of Heat Stress and Physical Exertion on Simple and Choice Reaction Time1
نویسندگان
چکیده
The effects of exercise on cognitive processes have been mainly approached, in recent years, through the study of reaction time tasks (Delignières, Brisswalter & Legros, 1994; Legros, Delignières, Durand & Brisswalter, 1992; Paas & Adam, 1991). These studies have shown that exercise led to a decrement of simple reaction time, but to an enhancement of choice reaction time, especially with collective and combat sports experts. These contrasting effects seemed related to a complex interaction between a specific influence of exercise on some cognitive processes (Arcellin, Delignières & Brisswalter, this volume), and a mental effort mobilization under exertion (Delignières, Brisswalter & Legros, 1994).

Effects of Heat Stress and Time on Task on Reaction Time1
Several studies have shown that heat stress caused a deterioration in cognitive performance, and that the magnitude of this deterioration was related to the duration of the exposure to high temperature. Particularly in sustained attention tasks, to which some sports activities could be compared, performance decrements were observed under heat stress, and these decrements became more important w...
