limited study about the effect of small sided games on VO2max performance among male futsal
players. The main purpose of this study was to measure the difference in VO2max, lactate
threshold and muscle endurance levels after 4 weeks of high intensity small sided games
training. Fourteen male futsal players were purposely selected to involved in this study,
