The Effects of Precooling Technique on Youth Soccer Maximum Aerobic Fitness at Phrapathomwitthayalai School in Nakhonpathom Province
Abstract
During competition of soccer games, the players have to play for long period of time in hot and humid weather which makes body temperature elevation. This caused problems in soccer players as physical fatigue and declining in physical performance skills. The objectives of this study were to determine the effects of precooling technique on maximum oxygen fitness in youth soccer players in the hot and humid weather. Thirty Subjects were recruited into 2 protocols in 2 difference days;rest in control day (Control) or immerge 28 Co water for 20 minutes in precooling day (Intervention) prior to cycling and intermittent sprint by Castle and colleague's protocol. All subjects were measured blood pressure (BP), heart rate (HR), respiratory rate (RR), core temperature (Tc) and rating of perceived on exertion scales (RPE) before and after protocols. The result of this study demonstrated that precooling technique significantly improved maximum oxygen fitness, lowered Tc and RPE (p<0.05). In conclusion, using precooling technique improve maximal oxygen fitness of youth soccer players in prolonged hot weather and humidity.
