Abstract
Objective: This study aimed to assess the effects of a resistance training program on NO and LA levels in obese and inactive women. Methods: A total of 20 women were divided into exercise (n = 10) and control (n = 10) groups. Anthropometric characteristics, NO, and LA levels were measured before and after a resistance training program in the exercise group, while the control group maintained their regular activities. Paired t-tests were used to compare pre-test and post-test results within each group, and independent t-tests were employed for between-group comparisons. Results: No significant differences were observed in baseline anthropometric characteristics between the two groups (p > 0.05). For the exercise group, NO levels significantly increased from 10.2 ± 2.3 µm to 14.6 ± 3.1 µm (p = 0.001), and LA levels decreased from 7.8 ± 1.6 mm to 5.1 ± 1.4 mm (p = 0.001). The control group showed no significant changes in either NO (p = 0.423) or LA (p = 0.512). Between-group comparisons revealed significant differences in NO (p = 0.002) and LA (p = 0.003) levels post-intervention. Conclusion: Resistance training significantly increased NO levels and decreased LA levels in obese and inactive women, indicating improvements in endothelial function and metabolic efficiency. These findings suggest that resistance training could be a valuable strategy for enhancing cardiovascular and muscular health in this population. Further research is needed to explore long-term effects and other influencing factors.
