Abstract

Objective: The objective of this study was to investigate the effects of eight weeks of parallel training conducted in the morning and evening on various anti-inflammatory cardiovascular indices in young overweight men.
Method: This quasi-experimental study utilized a control group and included pre-test and post-test assessments. It involved 40 young overweight men, with an average age of 25.12 years and an average weight of 85.78 kg. The participants were randomly assigned to four parallel training and control groups, with sessions conducted in both the morning and evening. The training program lasted for 8 weeks, consisting of three sessions per week, at an intensity of 75% to 85% of the maximum heart rate. Additionally, 5 ml of venous blood was collected from the subjects to measure inflammatory indices (CRP, IL-6), and the Block test was administered to assess VO2max. For statistical analysis, a one-way analysis of variance (ANOVA) was conducted using the Least Significant Difference (LSD) post hoc test, with a significance level set at 0.05. The analysis was performed using SPSS software version 27.
Findings: Eight weeks of parallel training in the morning and evening resulted in an increase in VO2max and a decrease in weight and body mass index in the experimental groups compared to the control groups. This study found that the increase in VO2max was greater in the evening compared to the morning, while the decrease in weight and body mass index was more significant in the morning than in the evening. Additionally, an 8-week parallel training program in overweight young men resulted in a significant increase in the anti-inflammatory cytokine IL-10 in the experimental groups compared to the control group. Notably, this increase was more pronounced in the evening than in the morning.
Conclusion: The conclusion is that parallel training conducted in the morning and evening is effective in improving the anti-inflammatory indices of the cardiovascular system. Additionally, it leads to a greater increase in anti-inflammatory factors in the evening compared to the morning. Therefore, evening training is likely a more suitable time for overweight individuals than morning sessions.
