Abstract

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.Subjects 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.Results: 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.Keywords: hemoglobin, muscular endurance, soccer  athletesCorrespondence: Nur Afni Heryanti Octavia.

Abstract

Background: Maintaining body mass index is one of the social problems, especially for young athletes. This study aimed to determine the relationship of body mass index (BMI) and age to muscular endurance in soccer athletes in Medan.Subjects and Method: This was a cross-sectional study soccer clubs in Medan, North Sumatera, Indonesia, in April 2018. A sample of 96 soccer players was selected for this study. The dependent variable was muscular endurance. The independent variables were BMI and age. Body weight was measured by weight scale. Body height was measured by microtoise. The other data were collected by questionnaire. Muscle endurance was assessed by 1 minute push up test. The data were analyzed by Person product moment.Results: BMI was positively correlated with muscle endurance but it was not statistically significant (r = 0.09; p = 0.390). Age was positively correlated with muscle endurance and it was statistically significant (r= 0.62; p= 0.001).Conclusion: BMI and age are positively correlated with muscle endurance among soccer players.Keywords: BMI, muscle endurance, soccer athleteCorrespondence: Dewi Maya Sarah.
