The effect of concurrent training on physical fitness factors related to health and the serum level of prostate-specific antigen in inactive men

Background & Aim: The purpose of this study was to investigate the effect of ۱۲ concurrent training on prostate specific antigen (PSA), cardiopulmonary endurance, muscular strength and body composition in men over ۵۰ years.Materials and Methods: In this quasi-experimental study, the statistical sample consisted of ۲۹ men with average weight of ۸۱.۱±۶.۷ kg and body mass index of ۲۶.۴±۱.۴ kg/m۲, randomly divided into two control untrained group (N=۱۲) and training group (N=۱۷). The concurrent training group performed concurrent training (endurance-resistance) training for ۱۲ weeks. Serum PSA levels, cardiopulmonary endurance (VO۲max), muscle strength, and body compositions were measured before and after training. Data were analyzed using covariance analysis (ANCOVA) (P <۰.۰۵).Results: Concurrent training in the training group significantly reduced PSA compared to the control untrained group (P=۰.۰۰۱). As well as training significantly decreased fat mass (P=۰.۰۴۶) and the ratio of waist to hip circumference (P=۰.۰۲۴) also significantly increased cardiorespiratory endurance (VO۲max) (P=۰.۰۰۱), mean relative muscle strength (P=۰.۰۰۱) and lean body mass (P=۰.۰۰۱) in the training group compared to the control untrained group. Conclusion: Overall, our findings showed that concurrent training (endurance-resistance) with increased cardiorespiratory endurance, mean muscle strength, and improved body composition decreased serum prostate-specific antigen (PSA) levels in Men over ۵۰ years old.
