Speed ratio but cabin temperature positively correlated with increased heart rates among professional drivers during car races.


OBJECTIVES The present study measures heart rate (HR) on a number of professional race-car drivers during actual car races through annual seasons to test hypotheses that faster relative speed and higher cabin temperature would induce higher HR. METHODS Heart rates in fifteen male drivers (31.2 ± 5.5 years old) were obtained by chest-strap sensors during… (More)
