| Summary: | Objective. This study aimed to investigate the effect of a balanced nutritional program on the electrical activity of muscles in some quadriceps weightlifters. The results will be analyzed to determine the extent to which nutrition affects muscle performance.
Research methodology. The researcher used the experimental method with a two-group design, a control group and an experimental group with pre- and post-tests, to suit the nature of the problem. The research sample was deliberately selected from the Baghdad Municipality Club’s four-legged players for the 2024/2025 sports season, numbering (36) weightlifters. They were randomly divided into two groups, with (18) weightlifters for each group. The nutritional program was applied to the experimental group only, and the control group relied on the nutritional program approved by the players and the club’s management.
Results. The results of the control group show insignificant differences in the muscle variable (erector dorsi) and significant differences in the muscle variable (femoris, anterior deltoid) for the variable (Peak EMG). Despite a slight improvement in peak electrical activity between the pre- and post-tests, this improvement resulted from the training and nutritional program approved by the trainer.
Conclusions. The experimental group demonstrated improved electrical activity in some quadriceps muscles, and the control group did not achieve significant differences in electrical activity in the muscles under study.
