Analysis of Energy Need and Adequacy of Athlete Based on Physical Activity Measurement Using Pedometer

摘要

Physical activity is an important component in measuring energy need of an athlete. Pedometer is a tool to estimate energy expenditure from physical activities based on footsteps. This study aims to analyze the differences of energy needed and adequacy on athlete based on physical activity measurement by using pedometer and calculation. This is an observational study with cross sectional design in 4 football school in Semarang. The samples of this study were 76 athletes aged 15-20 years old. The subject of study was selected by using consecutive sampling. Independent variable was energy expenditure from playing football measured by using pedometer and calculation. The dependent variable was energy need and adequacy. The data of food intake through recall of 3×24 hours. The means of energy adequacy based on energy expenditure from playing football is using calculation was 63,12±10,50 kcal, meanwhile by using pedometer was 70,57±12,70 kcal. The means of energy need based on energy expenditure from playing football is using calculation was higher than using pedometer, with the value of difference was 359 kcal. There was a difference in the means of energy need and adequacy based on energy expenditure from playing football by using calculation and pedometer.
