The Effect of Muscle Mass during Priming Exercise on Pulmonary Oxygen Uptake and Cardiac Output Kinetics

The Effect of Muscle Mass during Priming Exercise on Pulmonary Oxygen Uptake and Cardiac Output Kinetics

Show other versions (1)

The effective of additional muscle mass in a priming exercise on cardiac output (Q) and pulmonary oxygen uptake (VO2) kinetics (mean response time, s) were determined in cyclists. Outcomes were measured over four trials, each consisting of a 6-minute legs alone (UAL) or arms and legs (ULO) warm-up,...
