| Summary: | Background : Many badminton athletes prone to muscle fatigue during games or
at practice. At the moment that is anaerobic exercise, such as badminton, cause
fatigue due to a buildup of lactic acid in the muscles and blood. One of the efforts
made to overcome muscle fatigue is with the selection of the right meal.
Objective: To determine whether there is the effect low or high of glycemic index
meal (GI) to muscle fatigue badminton athletes.
Methods: Experimental studies with repeated measures design. Subjects are 20
male badminton athletes aged 19-25 years who meet the inclusion and exclusion
criteria have been determined. In a separate time (a week), subjects given high or
low GI meal, after 30 minutes made anaerobic shuttle test to assess muscle
fatigue.
Results: There are significant differences in glucose levels at the time after being
given a low or high GI foods (p = 0.021) and after anaerobic shuttle test (p =
0.000). Lactate levels there are significant differences before anaerobic shuttle test
(p = 0.007) and after anaerobic shuttle test (p = 0,02). Ingesting or and high IG
meal effect on muscle fatigue index (p= 0.009).
Conclusion: low or high glycemic index meal affect to muscle fatigue for
badminton athletes.Low GI meal can delay muscle fatigue in badminton athletes.
