Profile of Maximum Oxygen Uptake of Male Youth Athletes

Introduction: Cardiovascular endurance (CE) is one of the main bio-motor components that must be possessed by athletes to be able to support physical performance. In addition to being able to engage in physical activity for long periods, cardiovascular endurance is also needed to help and speed up the reversibility process of physical fatigue after exercising. The profile related to the athlete's endurance is very necessary to be held, which can be used for the process of monitoring and evaluating the effectiveness of the training program that has been given. Objective: This study aimed to determine the profile of cardiovascular endurance for male jun ior athletes of Track and Field (TF), Taekwondo (TK), Karate (KT), and SepakTakraw (ST). Methods: The method of study was a quantitative descriptive with a cross-sectional approach. A total sampling method was implemented to 60 athletes including 14 athletes ages 14-17 years old for TF, 20 samples of TK, 15 athletes of KT, and 11 athletes of ST who were prepared for Nat ional School Games. The test instrument for cardiovascular endurance used was a mult istage fitness test (MFT), with quantitative descriptive data analysis in percentages. Results: The results showed that athletes of track and field (TF) had an average value of VO2Max ranging from 35.0-38.3 ml/kg/minute, meanwhile fo r Karate (KT) had an average value of 33.2 36.5 ml/kg/minute. On the other side, athletes of Taekwondo (TK) have average cardiovascular endurance values ranging from 34.137.7ml/kg/minute and athletes of SepakTakraw (ST) have average endurance values ranging from 29.7-31.3 ml/kg/minute. Conclusions:The cardiovascular endurance profiles for Track and Field generally have good level categories, and so does for Taekwondo where in general also have good categories. Meanwhile, the profile of cardiovascular endurance for Karate state in an average category, on the other side SepakTakraw as generally has in a less category.
