Effect of acute high and low glycemic index consumption on anaerobic performance among handball players / Rahmat Abdul Patah

Introduction: The glycemix index was effected the blood concentration based on carbohydrate types in blood either its rapidly rises or slow. This blood glucose level in body can affect on energy storage in muscles. Both of high and low glycemic index was given an effect towards the performance of athletes before, during and after exercise. Purpose: This study will investigate the effect of acute high and low glycemic index consumption on anaerobic performance among handball players. Methods: Twenty-three handball athletes (N=23) were recruited by using convenience sampling methods. The familiarization was conducted three days before the pretest and also fill in consent form and weight in. The subject assessed through anaerobic performance test (30 meters sprint test, standing broad jump test) on pretest. One week wash period was given to the subject recovery time before post testing. During post test, athletes was consumed HGI and LG1 two hours before test after an
overnight fast. Each of athletes was completed three trials of 30 meters sprint test and standing broad jump test. Results: All of athletes achieved an improvement of performance on high GI treatment (P < .05) while the low GI treatment does not achieved improvement in performance (P > .05). Conclusion: The results indicate that HGI consumption can improved anaerobic performance however LGI better for endurance performance.
