Serum Leptin, Plasma Glucose, and Lactate Changes following Aerobic Exhaustive Incremental Exercise in Trained 18-26 Years Old Men

Aims: This study aimed to examine the acute effects of exhaustive incremental exercise on serum leptin, glucose, and lactate in one session in trained 18-26 years old men. Material Methods: The present study was conducted in 2021 on male physical education students available at the Faculty of Sports Sciences of the Shahid Chamran University of Ahvaz in Iran. Thirty students who had 18-26 years old, with body fat between 15-25% and VO2max between 35-45ml/kg/min, were simple randomly selected through 200 physical education students, and they were divided into two equal training and the control groups (each of them consists of 15 subjects). The exercise test included the Astrand test on a treadmill that performed exhaustive incremental exercise. Blood samples have been collected from two groups in pre and post-test and 9 hours after exhaustive incremental exercise. The statistical analyses used were the Independent T-test and one-way ANOVA tests by SPSS version 20. Findings: Results showed that serum leptin did not change between three measurement sets in the training group in comparison to the control group (p 0.05). Plasma glucose significantly changed between pre and post-test and pretest and 9 hours later (p 0.001). Plasma lactate significantly changed in post-test in comparison to pretest and 9 hours later to post-test (p 0.001). Conclusion: Incremental exhaustive exercise has no significant effect on serum leptin.
