摘要：Purpose.Maximal oxygen consumption (VO max) is defined as the ability to transfer and consume oxygen during exhausted work and is associated with cardiorespiratory fitness.The main purpose of this research is to measure and analyze the VO2max of eleven soccer players who compete in regional soccer league in Los Angeles.Additionally,secondary purpose of this study is to determine the relationship between VO2max values and heart rate,ventilation,RER,and V02,and CO2.Methods.Study participants included 11 male soccer players who competed in Los Angeles recreational regional league.All subjects performed a maximal exercise test using a treadmill with Bruce protocol.The tests starting at speed 2,74km/hr and grade of 10% and,gradually more increased at every 3 minutes until exhaustion.The following parameters were recorded from the cardiorespiratory exercise test: VCO /VO values,the duration of the test,the maximal pulmonary ventilation (VE),the maximal heart rate (HR),and the respiratory exchange ratio (RER).Descriptive statistics included calculation of mean values for subjects VO2 max,VCO2 /VO2 values,the duration of the test,the maximal pulmonary ventilation (VE),the maximal heart rate (HR),and the respiratory exchange ratio (RER).Correlation coefficients were also calculated to evaluate the relationships for each value.Results.The subjects reached VO2max because they meet at least 3 criteria’s for reaching VO2max and VO2 strongly correlated with all other verables.Conclusion.As expected VO2 values of eleven soccer players was closely related with heart rate,ventilation,RER,and V02,and CO2 of the subjects.
