Abstract

Aims: Zinc is a crucial and rare element in energy metabolism, but there is limited information regarding its impact on sports performance and weight changes. Consequently, this study aimed to investigate the effects of endurance training with zinc supplementation on endurance performance and weight in male Wistar rats.

Methods: A total of 28 adult male Wistar rats (8 weeks old) were randomly divided into four groups: control (6 rats), zinc supplementation (6 rats), endurance training (8 rats), and endurance training with supplementation (8 rats). Endurance training involved the use of a treadmill designed for rodents. Zinc supplementation was provided by dissolving 227 mg of zinc sulfate in one liter of water, which was continuously available to the animals. Maximum endurance capacity was measured at the end of the seventh week using a residual test, and the samples were weighed two days after the training sessions. The data were analyzed using ANOVA and Tukey's post hoc test, with a significance level of P≤0.05.

Results: The results indicated a significant increase in endurance performance in the endurance training group compared to the control group (P=0.001). Additionally, there was significant increase in endurance performance in the endurance training+supplement group compared to the endurance training group (P=0.036). Furthermore, no significant difference in weight changes was observed among the research groups (P=0.619).

Conclusion: Overall, combining zinc supplementation with endurance training shows promise for enhancing sports performance and improving energy balance.
