【 摘 要 】

Background: Muscular endurance is one of the important components of physical fitness in the sport of soccer player. Soccer athletes are required to contracting the muscle explosively as maximum as possible and must have high aerobic capability. This study aimed to determine the correlation between hemoglobin levels with muscular endurance in soccer athletes. Subject s and Method: This was an analytic observational study with a cross-sectional design. The population was soccer player athlete who was incorporated in soccer clubs and soccer schools at Medan, North Sumatera, Indonesia. A sample of 96 soccer athletes was selected for this study. The dependent variable was muscular endurance. The independent variables were hemoglobin levels. Hemoglobin level was measured by the cyanmethemoglobin method, and muscular endurance was measured by the push-up test. The data was analyzed using a Spearman test. Result s : Hemoglobin levels were positively correlated with muscular endurance levels and it was statistically significant (r = 0.226; p<0.05). Conclusion : This study showed hemoglobin levels correlates with muscular endurance.
