The effect of a training program on vitamin D levels and some fat-soluble vitamins on tennis players’ performance

Abstract

This study aimed to study the effect of a training program on vitamin D levels and some fat-soluble vitamins (vitamins A, E, and K), as well as the effect of the training program on tennis players' performance. It also aimed to study the relationship between vitamin D levels and some fat-soluble vitamins and tennis players' performance.

The researcher used a single-group experimental approach (pre- and post-test) to achieve the study objectives. The training program was implemented on the experimental group for 8 weeks, with 3 training sessions per week. The results showed statistically significant differences in favor of the post-tests in all studied variables after implementation. This demonstrates the effectiveness of the proposed training program in the presence of significant differences in vitamin D levels and fat-soluble vitamins. This indicates that exercise can contribute to improving vitamin levels in the body and enhancing athletic performance, physical abilities, and skills. The researcher recommends implementing similar training programs to improve tennis players' performance and overall health, and to pay attention to proper nutrition to ensure players receive the necessary vitamins and minerals to enhance athletic performance.
