Abstract

ABSTRACT

The purpose of this study was to compare the effects of two different pacing strategies during a 6 min exercise performance on average power output, VO₂ kinetics, deoxygenation in the vastus lateralis muscle, energy system contribution, average power output and blood lactate concentration. Eight young, healthy, male subjects (age 24 ± 3) completed two 6 min pacing strategies on a cycle ergometer; one bout was paced at a calculated fatigue threshold (FT) and the other began with a 12 s sprint and was paced 5 % below FT pace (5%2, work rate, anaerobic energy system contribution and energy consumption (p
