Research has shown that both dark chocolate and exercise training may have favorable effects on antioxidant function in obese cohorts. However, their combined effect has not been established. We assessed the influences of six weeks of dark chocolate consumption combined with jump rope exercise on antioxidant markers in adolescent boys with obesity. Fifty adolescent boys with obesity (age = 15 ± 1 years) were randomly assigned into one of four groups; jump rope exercise + white chocolate consumption (JW; = 13), jump rope exercise + dark chocolate consumption (JD; = 13), dark chocolate consumption (DC; = 12), or control (C; = 12). Two participants dropped out of the study. Participants in JW and JD groups performed jump rope exercise three times per week for six weeks. Participants in the DC and JD groups consumed 30 g of dark chocolate containing 83% of cocoa during the same period. Serum concentrations of superoxide dismutase (SOD), total antioxidant capacity (TAC), glutathione peroxidase (GPx), and thiobarbituric acid reactive substances (TBARS) were evaluated prior to and after the interventions. All 3 intervention groups noted significant ( < 0.01) increases in serum concentrations of TAC, SOD, and GPx from baseline to post-test. In contrast, all intervention groups showed significantly reduced serum concentrations of TBARS from pre- to post-test ( ≤ 0.01). Bonferroni post hoc analysis revealed that post-test serum concentrations of TAC in the JD group were significantly greater than C ( < 0.001), DC ( = 0.010), and JW ( < 0.001) groups. In addition, post-test serum concentrations of SOD in the JD group were significantly greater than C group ( = 0.001). Post-test serum concentrations of GPx in the JD group were significantly greater than C ( < 0.001), DC ( = 0.021), and JW ( = 0.032) groups. The post-test serum concentrations of TBARS in the JD group was significantly lower than C ( < 0.001). No other significant between-group differences were observed. The current study provides evidence that dark chocolate consumption in combination with jump rope exercise is more efficient in improving antioxidant capacity than dark chocolate consumption or jump rope exercise alone among obese adolescent boys.
研究表明，黑巧克力和运动训练可能对肥胖人群的抗氧化功能产生有益影响。然而，它们的联合作用尚未得到证实。我们评估了六周食用黑巧克力并结合跳绳运动对肥胖青少年男孩抗氧化指标的影响。五十名肥胖青少年男孩（年龄 = 15 ± 1岁）被随机分为四组之一；跳绳运动 + 食用白巧克力（JW；n = 13），跳绳运动 + 食用黑巧克力（JD；n = 13），食用黑巧克力（DC；n = 12），或对照组（C；n = 12）。两名参与者退出了研究。JW组和JD组的参与者每周进行三次跳绳运动，持续六周。DC组和JD组的参与者在同一时期食用30克含83%可可的黑巧克力。在干预前后评估血清中超氧化物歧化酶（SOD）、总抗氧化能力（TAC）、谷胱甘肽过氧化物酶（GPx）和硫代巴比妥酸反应物质（TBARS）的浓度。所有三个干预组均指出，从基线到测试后，血清中TAC、SOD和GPx的浓度显著（P < 0.01）升高。相比之下，所有干预组从测试前到测试后血清中TBARS的浓度均显著降低（P ≤ 0.01）。Bonferroni事后分析显示，JD组测试后血清中TAC的浓度显著高于C组（P < 0.001）、DC组（P = 0.010）和JW组（P < 0.001）。此外，JD组测试后血清中SOD的浓度显著高于C组（P = 0.001）。JD组测试后血清中GPx的浓度显著高于C组（P < 0.001）、DC组（P = 0.021）和JW组（P = 0.032）。JD组测试后血清中TBARS浓度显著低于C组（P < 0.001）。未观察到其他显著的组间差异。当前研究提供了证据，表明在肥胖青少年男孩中，食用黑巧克力并结合跳绳运动在提高抗氧化能力方面比单独食用黑巧克力或单独进行跳绳运动更有效。
