PENGARUH AKUT SUSU COKELAT DAN MINUMAN OLAHRAGA KOMERSIAL SEBAGAI MINUMAN PEMULIHAN PASCA LATIHAN PADA PROGRAM INTERVAL TRAINING (Studi Pada Sekolah Sepak Bola Universitas Diponegoro)

Background:.Diet after exercise is essential to restore the body to the condition before doing the exercises. Milk chocolate is believed to help restore depleted glycogen after exercise while commercial sports drinks speed up rehydration, reduce physiological stress of exercise, and supply the carbohydrate that used during exercise. Objective: To investigate the acute effect of chocolate milk and commercial sports drink on post-exercise recovery period in interval training program. Method: This research uses experimental methods. Subjects were students in the Football School of Diponegoro University (n = 10). The Subjects were assigned into one group then given three different treatments; mineral water, chocolate milk and commercial sports drink where each treatment were done within 1 week. The subjects were induced fatigue by doing interval training such as running 8 x 50 m and then the subject was treated and rested 15 minutes. Fatigue index measured by Running-based Anaerobic Sprint Test (RAST) Results: One Way ANOVA test of fatigue index value between groups showed significant differences (p = 0.044). There were significant differences in fatigue index values (p = 0.046) mineral water and sports drinks. Significant differences in fatigue index values (p = 0.021) was also found between milk chocolate and sports drinks group. The difference between the fatigue index values of mineral water with chocolate milk group showed no significant difference (p = 0723). Conclusion: Chocolate milk and commercial sports drink have some effects on post-exercise recovery period in interval training program.

PERBEDAAN NILAI TIDAL VOLUME, INSPIRATORY RESERVE VOLUME DAN INSPIRATORY CAPACITY ANTAR CABANG OLAHRAGA PADA ATLET USIA 6-12 TAHUN (Studi pada Cabang Olahraga Bola Voli, Sepak Bola, Renang dan Taekwondo di Kota Semarang)

Background: The peak of human body growth and development happens during childhood with different intensity of activities and exercise. It influences the level of physical fitness and health. This research states that daily exercise has a significant impact towards the function of cardiorespiratory system. Each kind of sport has different energy system depends on the kind and the intensity of exercise. Aim: To prove the difference tidal volume, inspiratory reserve volume and inspiratory capacity on athlete in age 6-12 between swimmer, taekwondo player, football player and volleyball player in Semarang. Method: This cross-sectional study was done in 20 male athlete age 6-12 each sport branches, being in total 80 athlete. Among respiratory functions test, TV,IRV and IC ware measured using Spirometer spirolab II. Kruskal-Wallis test and One-way annova was applied for statistical analysis. Result: Mean TV values volleyball athlete is 1,12 L, football athlete 1,06 L, swimming athlete 1,27 L and taekwondo athlete 0,89 L. Mean IRV values volleyball athlete is 0,54 L, football athlete 0,70 L, swimming athlete 0,71 L and taekwondo athlete 0,67 L. Mean IC values volleyball athlete is 1,66 L, football athlete 1,76 L, swimming athlete 1,91 L and taekwondo athlete 1,56 L. Swimmer athlete has higher VC, IRV and IC values than other athlete. Conclusion: There is a significant difference TV values between sport branches in athlete age 6-12. Beside that, there is not a significant difference IRV and IC values between sport branches in athlete age 6-12.
