ABSTRACTWe assessed the accuracy and inter-sessional reliability of traditional (manual) compared to automatic (AutoHR) heart rate (HR) clamping methods during submaximal intensity continuous cycling. On separate occasions, thirteen males cycled at an HR corresponding to 80% of the ventilatory threshold for 18 min. Cycling power output was adjusted using either manual or AutoHR methods, encompassing three trials per method.

ABSTRACTWe investigated whether a single heart rate clamped cycling session under systemic hypoxia affects the recovery of physical and psycho-physiological responses from residual fatigue compared to normoxia. On separate occasions, twelve trained males performed a 3-d acute training camp scenario. On days 1 and 3, participants cycled for 60 min at a constant heart rate (80% of ventilatory threshold).

Highlights•Power output and arterial oxygen saturation decreased at every increment of simulated altitude. •All indices of internal demand did not differ between sea-level and simulated altitudes ranging 2500–3500 m, though breathing difficulty was exacerbated at 4000 m. •Compared to sea-level, 3500 m provides the greatest reduction in external work (~34%) without increasing breathing difficulty during heart rate clamped cycling.
