distort or skew the underlying physiological response. Errant breaths were defined as a breath that was different to the mean of the surrounding 4 breaths by more than 4 times the standard deviation of the same surrounding 4 data points ( 22 ). Both datasets from each stage (unloaded to moderate and

changes in physiological responses ( American College of Sports Medicine, 2013 ). A wireless Polar RS300X heart rate monitor (Polar Electro Oy, Kempele, Finland) was used to assess participants’ heart rate during the Naughton treadmill protocol to ensure they achieved at least a moderate intensity. Upon

While the physiological responses to heat-based training have been widely considered, 1 , 3 perceived responses, like the session rating of perceived exertion (session-RPE), have received limited attention. 1 Moreover, the effects of cold- and hot-water recoveries on TL during exertional heat stress

Under our experimental conditions, the movement lasted a few seconds, thus the physiological response was not sufficient to increase circulating lactate concentration, nor to modify partial pressures of O 2 and CO 2 , and
