Abstract
Influence of Warm-Up Intensity on Submaximal Exercise Oxygen Uptake in Iranian Female National Futsal Players
Highlights
Oxygen uptake during submaximal exercise (VO2) and maximal exercise (VO2max) have an important role in physical performance [1]
The present study demonstrated that oxygen uptake in the end of sub maximal exercise after heavy intensity warm up was reduced, but was not significant difference after three conditions (p=0.055)
A lower O2 deficit implies a smaller requirement for energy production from anaerobic sources and is consistent with the lower rate of accumulation of blood lactate measured in sub maximal exercise [1]
Summary
Oxygen uptake during submaximal exercise (VO2) and maximal exercise (VO2max) have an important role in physical performance [1]. The initial delay is usually ascribed to the cardio dynamic phase mainly linked to an increased pulmonary perfusion [3] while the subsequent fundamental phase has generally been reported to closely reflect (within 10%) the oxygen consumption at the muscle level [5]. Several investigators have reported beneficial effects of preliminary (warm-up) exercise during subsequent exercise in human athletes and have attributed these improvements in performance to a variety of mechanisms [6]. It has been proposed that warm-up bouts can accelerate the rate-limiting steps in oxidative reactions and improve release of oxygen from haemoglobin and myoglobin [1]
