| Objective: Physical activity is associated with higher left ventricular mass but also reduced risk of cardiovascular outcomes. The purpose of the present research was to investigate the effect of twelve weeks of resistance training and a detraining period on relative left ventricular wall thickness in inactive men. Method: Twenty-four inactive men who met the inclusion criteria and were able to participate in the exercise protocol were randomly divided into two resistance training groups (n=12) and control group (n=12). Anthropometric characteristics, body composition, and relative wall thickness (RWT) were measured using echocardiography at three time points: before the start of exercise, at the end of 12 weeks of exercise, and after a 6-week period of non-exercise. The exercise protocol consisted of 12 weeks of exercise (three sessions per week) followed by 6 weeks of non-exercise. Data were analyzed using independent t-tests and repeated measures analysis of variance at a significance level of p < 0.05 using SPSS software version 24. Results: The results showed that a significant change in RWT was observed between pre-test and post-test measurements in both groups (p < 0.05) and significant changes in RWT were also observed during the detraining period in the training group (p < 0.05). Conclusion: It can be concluded that 12 weeks of resistance training can lead to beneficial changes in cardiac structure in inactive men. A 6-week detraining period can lead to negative effects on these adaptations. | ||
