Purpose To assess relationships between heart rate (HR), ventilation (̇ $$\dot V$$ V ˙ E ), and respiratory frequency (F R ) decoupling and durability of the first ventilatory threshold (VT 1 ), and the strength of practical models to predict power output at VT 1 during prolonged exercise. Methods Durability of VT 1 was assessed via measurements of power output at VT 1 before and after ~ 2.5-h of initially moderate-intensity c...

Purpose To determine the effect of taurine supplementation on sweating and core temperature responses, including the transition from compensable to uncompensable heat stress, during prolonged low-intensity exercise of a fixed-heat production (~ 200W/m 2 ) in hot conditions (37.5 °C), at both fixed and incremental vapour-pressure. Methods Fifteen females ( n = 3) and males ( n = 12; 27 ± 5 years, 78 ± 9 kg, $$\dot{V}$$ V ˙ O 2m...
