Abstract

Objective: The purpose of this study was to investigate the effect of 12 concurrent trainings on prostate specific antigen (PSA), cardiopulmonary endurance, muscular strength and body composition in men over 50 years.
 
Materials and Methods: In this quasi-experimental study, the statistical samples consisted of 29 men with an average weight of 81.1±‏6.7 kg and body mass index of 26.4‏±‏1.4 kg‏/m2, randomly divided into two control untrained group (n=12) and trained group (n=17). The concurrent training group performed concurrent training (endurance-resistance) for 12 weeks. Serum PSA levels, cardiopulmonary endurance (VO2max), muscle strength, and body composition were measured before and after training. Data were analyzed using covariance analysis (ANCOVA) (P<0.05).
 
Results: Concurrent training in the training group significantly reduced PSA compared to the control untrained group (P=0.001). As well, training significantly decreased fat mass (P=0.046) and the ratio of waist to hip circumference (P=0.024) and significantly increased cardiorespiratory endurance (VO2max) (P=0.001), mean relative muscle strength (P=0.001) and lean body mass (P=0.001) in the training group compared to the control untrained group.
 
Conclusion: Overall, our findings showed that concurrent training (endurance-resistance) increases cardiorespiratory endurance, mean muscle strength, improves body composition and decreases serum prostate-specific antigen (PSA) levels in men over 50 years old.
