Biochemical Changes In Athletes' Bodies During Physical Exercise
Keywords:
Exercise, physical activity, creatine phosphokinase, aspartate aminotransferaseAbstract
This study explores the general patterns and characteristics of enzyme activity changes in athletes' bodies during physical exercise. Increased enzyme activity results from biochemical changes in cells triggered by intense or prolonged muscle activity. Short-term physical exertion typically leads to a rapid return of enzyme activity to normal levels during rest. However, a sustained increase in enzyme activity may indicate excessive training intensity. In sports practice, the activity levels of creatine phosphokinase (CPK), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) are commonly measured to evaluate athletes’ functional states and the effects of training.
