COMPARISON OF ACTIVE AND PASSIVE RECOVERY IN DIFFERENT INTENSITY BETWEEN SETS AND AFTER RESISTANT TRAINING

Abstract

    The purpose of this research was to study the comparison of active and passive recovery in different intensity between sets and after resistant training. The subjects consisted of a simple random sampling selection of 30 male students aged 18-22 years old from Burapha University by divide 3 groups. The first and second group performed recovery by walking on treadmill at level 40-45% and 50-55% for maximum heart rate. And the third group performed recovery which resting. Each composition of 3 sets of leg extension exercise performed for maximum weight at 10 times. Each set was separated by 4 minutes recovery period. During the data collection, blood sample for lactic acid, leg muscle strength and soreness sensation of leg muscle: pre-exercise, between-sets and after-sets recovery period.

    The result of research showed that the recovery by walking on treadmill at intensity level 40-45% of maximum heart rate which it effectively manage and reduce the lactic acid in blood better than intensity level 50-55% of maximum heart rate and recovery by resting state. All the recovery of 3 forms, it does not change the strength of the leg muscle and the increased level of awareness of leg muscle pain is not different. Then, it could be a guideline for selection the appropriated level of intensity with the recovery activities movement.
