الملخص EN

The 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 Enzyme Lactate dehydrogenase )LDH).

The sample consisted (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.

(LDH) were measured at rest and recovery, Data were processed statistically treated by using (ANOVA) test.

After presenting and discussing the results, the research concluded that the depleted load of upper, lower and mixed exercises significantly affected in the enzyme lactic dehydrogen (LDH) in conditions (7 minutes, 20 minutes), and no significant effect was observed in the condition (post-effort, 30 minutes).

When comparing between conditions of the upper, lower and mixed exercises, there was significant effect for all upper, lower and mixed exercises, with the only exception being that the conditions (20 minutes, 30 minutes) for the upper, lower and mixed exercises and the conditions (7 minutes, 20 minutes) for the lower extremity.
