effects of acute resistance training on biochemical markers of myocardial injury (ctnt, ctni, ck-mb) in non-athletewomen

Background: the purpose of this study was to evaluate the effects of acute resistance training on changes in biochemical markers of myocardial injury (ctnt, ctni, ck-mb) in non-athlete women. methods: in this study, 18 healthy young women with a mean age (23.41 years) and body fat percent (21.62) participated voluntarily. untrained women performed 7 resistance exercises at 70% 1rm in 3 sets and 10 repetitions. rest interval between sets was 2 min- utes. blood samples were obtained before, immediately, 1, 24, and 48 hours after exercise. statistical analyses were conducted using anova with repeated measure (p ≤ 0.05). results: the results revealed a significant difference in troponin i in pre-test immediately and 1 hour after exercise, but 24 hours and 48 hours after, it returned to baseline. there was also a significant difference in troponin t and ck-mb in pre-test immediately and 1 hour and 24 hours after exercise, but they returned to baseline after 48 hours. conclusions: it can be concluded that resistance exercise may lead to an increase in cardiac troponin and ck iso-enzyme. however, it seems to be a temporary increment and do not cause cardiac damage.
