The Effects of Intensity of Warm up on Slow Component of Vo2 and Cordiorespiratory Index during Submaximal Exercise in the Iranian National Female Fustal Players Team

The purpose of this study was to examine the effects of intensity of warm on slow component of VO2 and cardiorespiratory index during submaximal exercise in the Iranian national female futsall players team. The participants of this study were ten Players of Iranian futsall national team (mean± SD age, 22.5±3.2yrs weight, 56.04±6.17kg height, 163±3.67cm body fat%, 23.5±3.8 BMI, 21.07±2.22kg/m2 VO2max, 46.05±4.61 ml.kg-1.min-1). After measuring of VO2- max and LT, the subjects performed two protocoles of warm up (moderate and heavy intensity) and one protocole without warm up before submaximal exercise (80%LT) in three separated sessions. Respiratory gas exchange measured by Gas Analyser during the exercise. Repeated measures were applied for statistical analysis. After moderate and heavy warm up, oxygen uptake in slow component reduced but not significantly due to without warmup (p<0.05). Also the result show between oxygen uptake and ventilation was posetive correlation (r=0.51). The results suggest that warm up causes improved the athletes performance via improved oxygen uptake and cardiorespiratory in slow component.
