Acute effects of different intensities of resistance training on blood glucose, triglycerides, and total cholesterol in young men

Abstract

This study examined the acute effects of different intensities of resistance training on blood glucose, triglycerides, and total cholesterol levels in healthy young men. Twelve participants with prior resistance training experience were included, and they performed a one-repetition maximum (1RM) test to assess their maximal strength capacity. Four experimental sessions were conducted, targeting both the upper and lower body. Blood glucose, triglycerides, and total cholesterol levels were measured before and after each session. Statistical analysis revealed a significant decrease in blood glucose levels after resistance training with 5 and 10 repetitions. There were no significant differences in total cholesterol levels across different repetition intensities. However, triglyceride levels significantly decreased after all repetition intensities, with significant differences observed in the 15 and 20 repetitions. In conclusion, acute resistance training at different intensities has immediate effects on specific metabolic markers, such as blood glucose and triglycerides, in healthy young men.
