the effect of a futsal match on some biochemical markers of muscle damage (cr & ast)

high intensity workout provokes damage in muscles with an effect on muscle physiology and function. today, serum levels of creatine and aspartate aminotransferase are widely used as biochemical markers of muscle damage in order to determine the functional status of muscle tissues in both pathological and physiological conditions. this study investigated the effect of a futsal match on some biochemical markers of muscle damage such as creatine (cr) and aspartate aminotransferase (ast). 20 professional female futsal players (mean ± sd: age 20.9±2.02 yr, height 1.63±0.05 m, weight 59.25±8.92 kg) participated in this study. the subjects were divided into experimental and control groups. 10 participants took part in a futsal match and 10 subjects did not participate in the match as the control group. 10 cc of blood were collected from both groups before, immediately after (first posttest) and 24 hours after the match (second posttest) to measure cr and ast and were analyzed by biochemical methods. analysis of variance with repeated measures and bonferroni post hoc test were used for data analysis. the results showed a significant increase in ast immediately after the match (p≤0.05). but there was no significant difference between the groups. cr showed a significant difference immediately after the match between the two groups (p≤0.05), that is to say it increased 21% in the first posttest in the experimental group compared with the control group. it can be concluded that a futsal match can increase serum concentrations of cr and ast that represents the risk of muscle damage in female futsal players.
