The aim of this study was to investigate the responses of creatine kinase (CK) and lactate dehydrogenase (LDH) after performing different resistance and aerobic exercise protocols. Twelve recreationally trained men (age, 23.2 ± 5.6 years; body mass, 84.3 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 26.3 ± 2.3 kg·m2) volunteered to participate in this study. All subjects were randomly assigned to four experimental protocols (crossover): (a) aerobic training at 60% of VO2max, (b) aerobic training at 80% of VO2max, (c) a resistance exercise (RE) session with a bi-set protocol, and (d) an RE session with a multiple sets protocol. Blood samples were collected before, immediately after and 24 hours following the experimental protocols. After 24 hours, there was a significant increase in CK for the 80% of VO2max protocol vs. the bi-set RE session (p = 0.016). Immediately after the protocols, we observed a significant increase in LDH among certain groups compared to others, as follows: multiple sets RE session vs. 60% of VO2max, bi-set RE session vs. 60% of VO2max, multiple sets RE session vs. 80% of VO2max, and bi-set RE session vs. 80% of VO2max (p = 0.008, p = 0.013; p = 0.002, p = 0.004, respectively). In conclusion, aerobic exercise performed at 80% of VO2max appears to elevate plasma CK levels more than bi-set RE sessions. However, the bi-set and multiple sets RE sessions appeared to trigger greater levels of blood LDH compared to aerobic protocols performed at 60% and 80% of VO2max.
本研究的目的是调查在执行不同的抗阻和有氧运动方案后肌酸激酶（CK）和乳酸脱氢酶（LDH）的反应。十二名受过休闲训练的男性（年龄，23.2±5.6岁；体重，84.3±9.3千克；身高，178.9±4.5厘米；BMI，26.3±2.3千克·米²）自愿参与本研究。所有受试者被随机分配到四种实验方案（交叉设计）：（a）以最大摄氧量（VO2max）的60%进行有氧训练，（b）以VO2max的80%进行有氧训练，（c）采用双组方案的抗阻运动（RE） session，以及（d）采用多组方案的RE session。在实验方案之前、之后立即以及之后24小时采集血样。24小时后，与双组RE session相比，VO2max的80%方案的CK显著增加（p = 0.016）。在方案之后立即，我们观察到与其他组相比，某些组的LDH显著增加，如下：多组RE session与VO2max的60%相比、双组RE session与VO2max的60%相比、多组RE session与VO2max的80%相比以及双组RE session与VO2max的80%相比（分别为p = 0.008、p = 0.013、p = 0.002、p = 0.004）。总之，以VO2max的80%进行的有氧运动似乎比双组RE session更能提高血浆CK水平。然而，与以VO2max的60%和80%进行的有氧运动方案相比,双组和多组RE session似乎会引发更高水平的血液LDH。
