acute response of muscular damage biomarkers after hift exercise in overweight men

Purpose: the aim of this study was to investigate the acute effects of hift exercise, on creatine kinase (ck) and lactate dehydrogenase (ldh) in blood serum in overweight adult men.method: twenty-two untrained non-smoker overweight men (age, 42.9 ± 5.6 years; body mass, 94.2 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and bmi, 29.04 ± 3.3 kg/m2) volunteered to participate in this study and performed a session of hift exercise with 80-85% hrmax consisting of three sets of 10 exercises. blood samples were collected before and immediately after training to measure serum ck and ldh levels.results: the hift protocol significantly increased serum ck (pre: 114.6 u/l; post: 124.3u/l; p< 0.05{t=-5.48, p=0.001}); also, ldh had a significant increase (pre:213.4 u/l, post: 225.4u/l; p<0.05{t=-4.09, p=0.001}). conclusion: it can be concluded that hift with amrap (as many repeats as possible) protocol will lead to a significant increase in some indicators of muscle damage such as ck and ldh levels in overweight men. this protocol can lead to muscle damage in overweight men.
