Objective To understand the intervention effect of different badminton intervention methods on the cardiopulmonary endurance index of ethnic Korean obese male college students, and to provide support for effectively weight loss cardiorespiratory endurance improvement.
Methods Sixty ethnic Korean male college students were randomly divided into intervention group 1, intervention group 2 and intervention group 3. The intervention of different intensity were carried out for 12 weeks, BMI, systolic blood pressure, diastolic blood pressure, static heart rate, vital capacity body mass index and the 20-meter round-trip performance were compared before and after the intervention.
Results After 12 weeks of small-intensity intervention, ethnic Korean obese male college students had no significant difference in the interventions before and after intervention. In the middle intensity group, the body mass index and diastolic blood pressure index were significantly lower than those before the intervention, and there was statistical significance ( t = –3.70, –4.15, P<0.01). After intervention in the high-intensity group, body mass index, systolic blood pressure, and diastolic blood pressure index were significantly lower than those before the intervention ( t = 3.69, 3.14, 4.43, P<0.01). After intervention in the lung capacity and body mass index, 20 m round-trip operation Significantly higher than before intervention ( t = –3.52, –5.31, P<0.01).
Conclusion Moderate and large intervention methods can improve the cardiorespiratory strength of ethnic Korean obese college students, especially in the high-intensity group.
【摘要】目的 了解羽毛球运动对朝鲜族超重肥胖男大学生心肺耐力指标的干预效果, 为有效降低超重肥胖大学生 体重及提髙心肺耐力水平提供支持。 方法 在延边大学招募 60 名超重或肥胖的朝鲜族男大学生, 进行身髙和体重的测 试, 将被试随机分为干预1组 (小强度组)、2 组 (中强度组) 和 3 组 (大强度组), 进行 12 周不同强度的干预, 对干预前后的 体质量指数 (BMI)、收缩压、舒张压、静态心率、肺活量体质量指数、20 m 往返跑成绩进行比较。 结果 经过 12 周小强度干 预后, 朝鲜族超重肥胖男大学生各项指标干预前后差异均无统计学意义 ( P 值均>0.05); 中强度组BMI、舒张压指标干预后 低于干预前, 差异均有统计学意义 ( t 值分别为 –3.70, –4.15, P值均<0.01); 大强度组干预后 BMI 、收缩压、舒张压指标均降 低 (t值分别为 3.69, 3.14, 4.43, P值均<0.01), 肺活量体质量指数、20 m 往返跑干预后髙于干预前 (t值分别为 –3.52, –5.31, P值均<0.01)。 结论 中大强度干预方式能改善朝鲜族超重肥胖大学生的心肺耐力, 尤其是大强度组改善效果最 为显著。
