Determining the Impact of Resistance, Aerobic, and Combined Training on Salivary Malondialdehyde Levels in Active Old Men

Abstract

Introduction: This study aimed to determine the effect of resistance, aerobic, and combined exercises on salivary malondialdehyde levels in active old men.Methods: This semi-experimental study used a pre-test and post-test design with three training groups. A total of 36 subjects were randomly divided into three groups with 12 participants each (1. resistance training, 2. aerobic training, and 3. combined training). The salivary malondialdehyde value in subjects was evaluated and recorded using a spectrophotometer with a colorimetric method. The subjects then performed relevant training protocols for eight weeks, after which the post-test data were evaluated and recorded under conditions similar to the pre-test. Statistical analysis was performed using descriptive statistical tests, dependent t-test, one-way ANOVA, and Scheffe post-hoc in SPSS version 24. The significance level was set at 0.05. Results: The results showed that salivary malondialdehyde significantly increased after applying aerobic, resistance, and combined training (p < 0.001). This increase was 29.7%, 19.5%, and 11.1% for combined, resistance, and aerobic training, respectively.Conclusion: According to this study’s findings, trainers and designers of elderly training programs should use combined training more frequently to benefit more from exercise’s antioxidant effects and improve total antioxidant capacity.
