This study was conducted to evaluate the effect of the different intensity levels of single-session aerobic exercise on serum levels of lipid peroxidation and muscle damage markers in sedentary males.
Fifty one sedentary healthy males aged 21.76±1.89 years were randomly divided into four groups, with one control (n=10) and three treatment groups that attended single-session aerobic exercise with low (n=14), moderate (n=14), and high (n=13) intensities. The serum levels of malondialdehyde (MDA) and creatine kinase (CK) were measured.
Data analysis revealed a significant effect by the intensity levels of aerobic exercise on MDA (P=0.001) and CK (P=0.003) post-test when the participants in the treatment groups were compared with the control. When the intensity of aerobic exercise was increased, the amount of MDA and CK was also found to be increased.
Single-session aerobic exercise can increase the amount of MDA and CK, suggesting that low intensity level of aerobic exercise should be utilized for more adaptation, and to prevent lipid peroxidation and muscle damage in sedentary males.
本研究旨在评估单次有氧运动不同强度水平对久坐男性血清脂质过氧化水平和肌肉损伤标志物的影响。
51名年龄在21.76±1.89岁的久坐健康男性被随机分为四组，一组为对照组（n = 10），三组为治疗组，分别进行低强度（n = 14）、中等强度（n = 14）和高强度（n = 13）的单次有氧运动。测量血清丙二醛（MDA）和肌酸激酶（CK）水平。
数据分析显示，与对照组相比，治疗组参与者在测试后，有氧运动强度水平对MDA（P = 0.001）和CK（P = 0.003）有显著影响。当有氧运动强度增加时，MDA和CK的量也增加。
单次有氧运动可增加MDA和CK的量，这表明应采用低强度水平的有氧运动以获得更多适应性，并预防久坐男性的脂质过氧化和肌肉损伤。
