Impact of a Submaximal Warm-Up on Endurance Performance in Highly Trained and Competitive Male Runners.

Purpose: The purpose of this investigation was to examine the effects of a submaximal running warm-up on running performance in male endurance athletes (n = 16, M = 21 ± 2 years, M = 69.3 ± 5.1 mL/kg/min).

Dynamics of Perceived Exertion in Constant-Power Cycling: Time- and Workload-Dependent Thresholds.

Purpose: The purpose of this study was to test the dynamics of perceived exertion shifts (PES) as a function of time and workload during constant-power cycling.

Method: Fifty-two participants assigned to 4 groups performed a cycling task at 4 different constant workloads corresponding to their individual rates of perceived exertion (RPEs = 13, 15, 17, and 19, respectively). PES ("increased"/"decreased" perceptions) without magnitude were reported when they occurred.
