AbstractThe purpose of the study is a comparative study of the effect of exhaustive load for upper and lower limb exercises and mixed exercises on stages of recovery in concentration of Growth Hormone. The sample consisted of (8) students aged (19-26) years and they were subjected to a six-week training program to avoid injuries that occurred during the implementation of the main tests. The main tests consisted of three exhaustive exercises (Bench press exercises for the upper limb), Squat exercises for the lower limb, mixed exercises (Bench press exercises and squat together)), at intensity (70%) and rest interval between the exercise groups consisted of (30) seconds for all exercises, and between the test and the last (72) hours. The growth hormone were measured at rest and recovery, data were processed statistically treated by using (ANOVA) test. When comparing the upper, lower, and mixed exercise, a significant effect was observed in the condition (post-effort, 7 min, 20 min, 30 min), a significant effect was observed in the recovery conditions (post-effort, 7 min, 20 min, 30 min), and significant effect was observed in the Recovery conditions for upper limbs (Rest-post-effort, 7 min-20 min, 20 min-30 min), The lower limbs (rest-post-effort, 7 min-20 min) and mixed exercise ((rest-post-effort, 20 min-30 min)). These results indicate that the resistance exercises at intensity (70%) and rest (30) seconds between the groups resulted in a significant effect of the study variables in the mixed exercise more than the exercises of the upper and lower limbs, and lower limbs exercises more than the exercises of the upper limbs. In conclusion, study had recommended considering the period of rest between the training modules when training using weights for exercises that based on the lactate system. trainers should take into account the periods of recovery in the competitions that rely on the lactate system as a common system.
