PHYSIOLOGICAL AND BIOCHEMICAL CHANGES IN ADOLESCENTS AFTER HIGH-INTENSITY TRAINING

ABSTRACT Introduction Exercise intensity can approach an individual’s maximum capacity rapidly. High-intensity exercise can improve aerobic capacity in obesity, overweight, heart disease, and diabetes. Knowledge of the physiological and biochemical changes in the post-workout period could provide safety indexes for a scientific basis. Objective To evaluate the immediate physiological and biochemical changes in adolescents submitted to high-intensity sports training. Methods The article selects several young athletes for research. They were randomly divided into two groups. Group A did high-intensity exercise, and group B did regular exercise. A statistical analysis of physiological and biochemical indicators of athletes before and after exercise is done. Results The vital capacity in the two groups was significantly different. However, no significant differences were found between the biochemical indicators collected before and after training. Conclusion High-intensity sport can improve cardiopulmonary function with low impact on biochemical indicators. These findings indicate high-intensity physical training can improve sports performance without compromising the health of adolescents. Evidence Level II; Therapeutic Studies - Outcome Research.
