Abstract

Objectives: The purpose of this study was to examine relationship protein intake with muscle strength of athletes. Methods: The research was conducted by cross sectional design between September to October 2016. The number of sample in this research was 20 male table tennis athletes (age 20 + 3.4 y.o. , weight 56.7 + 12 kg, height 162.4 cm + 8.9 cm). The instruments for measurement of muscle strength used handgrip dynamometer used. The consumption data was obtained by questionnaire of food recall 1 x 24 hours. Correlation between protein intake with muscle strength were analyzed using pearson correlation test. Results: The result of the research showed that average of energy intake of athletes were 2.134 + 231 kcal, the average of protein intake was 77.6 + 21.1 g, the average intake of carbohydrate was 370.9 + 49.5 g, and theaverage intake of fat was 47.2 + 12.1 g per day. In addition,the energy intake was up to 76.5% of the demand of energy in a day, the protein intake was 73.7% and the fat intake was 51,8% from that of needed by an athlete. The results showed that the maximum score of muscle strength data was 65 kg and minimum score of muscle strength data was 24 kg. The average score of muscle strength data was 46.0 + 13.3 kg. Conclusions: Most of the muscle strength data of table tennis athletes was very good. There was no significant correlation between energy consumption and protein intake with muscle strength of athletes (p > 0.05).
