Investigating the effect of temperament on the indices of muscle damage after acute resistance exercise in non-athletic men

Exercise is considered as an important factor in maintaining health in Iranian traditional medicine. Scientists believe that every sport exercise brings about specific effects. In traditional medicine, temperament is considered as a fundamental factor in creating individual differences. This study aimed to investigate the effect of temperament on muscle damage after resistance exercise. This study was a practical and quasi-experimental research. The participants were 38 single men aged 18-26 years. They were assigned to two groups, one including 18 cold-tempered participants and the other composing of 20 warm-tempered ones. Subsequently, the muscle strength test was performed in the two groups. Before and immediately after the exercise, blood samples were taken from the both groups and the enzymes were examined in the laboratory. The data were analyzed through independent T-test and
Mann–Whitney U test using SPSS 21. The results showed that the relative muscle strength in warm-tempered individuals was significantly higher than that in the cold-tempered ones. Also, Creatine phosphokinase enzyme was significantly higher in warm-tempered group than that in the cold-tempered one. However, lactate dehydrogenase was not significantly different between the two groups at the pre- and post-test stages. The significance level was considered to be 0.05 (p≤0.05). It can be concluded that warm-tempered participants enjoy higher power, but if they exercise to be healthy, they should begin resistance training program with a lower percentage of their one repetition maximum (1RM) to reduce the damage to muscles.
