The purpose of this study was to evaluate the effect of acute resistance training on Changes in biochemical markers of myocardial injury (cTnT, cTnI, CK-MB) in non-athlete women.
In this study 18 Healthy young women with a mean age (23.41) and body fat percent (21.62) participate voluntary. A week after determining 1RM, the subjects took part in a session of resistance exercise, which included chest press, leg press, shoulder press, biceps, knee flexion, cable lat pushdown and triceps cable pushdown. Each movement was performed in three sets and 10 repeats at 70% of 1RM, with two minutes resting period between sets and movements.Samples of 3 ml venous blood were taken from participants' brachial vein under the same conditions on five time points: before training program, immediately, 1h, 24h and 48h after training. Samples taken on the second occasion (immediately after training) were sent to Hakim private laboratory, where they were centrifuged at 2700 rpm for 15 minutes, and the serum was partly transferred to test tubes. Statistical analyses were conducted using ANOVA with repeated measure. (P≤0/05)
Our results show that there was significant difference in Troponin I in pre-test with immediately and 1-h after exercise. But, after 24 and 48-h returne to baseline. Also, there was significant difference in Troponin T and CK-MB in pre-test with immediately, 1and 24-h after exercise. But, after 48-h returne to baseline.
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 sustained cardiac damage.
