This study evaluated the change in blood oxidative stress, blood interleukin-2, and physical performance following 6 weeks of moderate intensity and duration aerobic dance exercise in 24 sedentary women. Blood samples were collected at rest twice before (baseline) and after the 6-week intervention for analysis of protein hydroperoxide (PrOOH), malondialdehyde (MDA), total anti-oxidant capacity (TAC), and interleukin-2 (IL-2) levels. Maximal treadmill run time (Time(max)) and maximal oxygen consumption (VO(2max)) were also measured. All variables were statistically analyzed with a repeated measurement ANOVA and Tukey post hoc. No differences were noted in any variable during the baseline period (p > 0.05). After aerobic dance exercise, VO(2max), Time(max), TAC and IL-2 were significantly increased, whereas MDA levels were decreased significantly (p < 0.05). PrOOH did not change either between baseline measures or after exercise. It can be concluded that aerobic dance exercise at a moderate intensity and duration can improve physical fitness, decrease MDA, and increase TAC and IL-2 in previously sedentary women.
本研究评估了24名久坐不动的女性在进行为期6周的中等强度和时长的有氧舞蹈锻炼后，血液氧化应激、血液白细胞介素-2和身体机能的变化。在6周干预前后的静息状态下分别采集两次血样，用于分析蛋白质氢过氧化物（PrOOH）、丙二醛（MDA）、总抗氧化能力（TAC）和白细胞介素-2（IL-2）水平。同时测量最大跑步机跑步时间（Time(max)）和最大耗氧量（VO(2max)）。所有变量均采用重复测量方差分析和Tukey事后检验进行统计学分析。在基线期，任何变量均未观察到差异（p>0.05）。有氧舞蹈锻炼后，VO(2max)、Time(max)、TAC和IL-2显著增加，而MDA水平显著降低（p<0.05）。PrOOH在基线测量之间或运动后均未发生变化。可以得出结论，中等强度和时长的有氧舞蹈锻炼可以改善久坐女性的身体素质，降低MDA水平，并提高TAC和IL-2水平。
