Abstract

Abstract :

Physical exertion is considered one of the key factors influencing athletic performance, as maintaining proper fluid balance in the body contributes to improved results, especially in endurance races that require continuous effort to sustain speed and optimal performance.

This study aims to examine the effect of high-intensity and moderate-intensity physical exertion on body fluid levels and performance in a 200-meter endurance race. It seeks to identify statistical differences between the two groups in these variables. The experimental method was used with a two-group design, and the sample consisted of 40 female students from the Sports Science and Physical Activity program at Princess Nourah bint Abdulrahman University.

The results showed statistically significant differences between the pre- and post-tests in favor of the group subjected to moderate-intensity physical exertion, as it improved fat-burning rates and performance levels. In contrast, high-intensity exertion led to a significant decrease in body fluid levels and an increase in fat burning but had a negative impact on race time performance. These findings emphasize the importance of balancing exercise intensity and hydration levels to achieve optimal athletic performance.
