【 摘 要 】

Muscle fatigue is a condition of discomfort, decreased efficiency due to excessive activity, loses energy / stamina, a common non-specific symptom experienced by many people and is associated with many health conditions which leading to achievement and performance to decrease. This study aimed to determine the effect of moderate physical activity (AFS) to muscle fatigue on untrained people. This investigation compared levels of lactic acid and the Borg scale before and after AFS. Fifteen man ages from 15 to 20 years volunteered to participate in the study. The subjects of the study were given moderate physical activity in the form of stepping up and down test until they reach the targeted maximum heart rate which is 70-79% for 15-20 minutes, 3 times a week for 4 weeks. Muscle fatigue was obtained by looking at the levels of lactic acid and the Borg scale before and after AFS. The results show the decrement after the AFS for the both lactic acid and the Borg scale with the mean levels of 9.02 ± 2.55 before AFS and 6.00 ± 2.76 after the AFS for the lactic acid and 3.70 ± 0.94 before AFS and 1.80 ± 1.0 after AFS for the the Borg scale tightness. It was found that AFS on untrained people can reduce muscle fatigue and the physical ability can be improved by exercise with appropriate intensity, duration and frequency.
