          Objective To investigate effectiveness of different intensities of basketball exercise on body compositions among obese junior middle school students, and to provide theoretical support for healthy weight loss among obese children and adolescents.

          Methods From September to November 2020, a typical sampling method was used to select 48 obese junior middle school students were recruited from Wuhan Optical Valley Experimental Middle School according to body mass index (BMI), all the students were divided into high, moderate and low-intensity basketball training group, as well as the control group, the 45 min per times basketball exercise intervention was administered three times per week for 12 weeks, while the control group did not received no intervention, body composition was assessed before and after intervention.

          Results After 12 weeks of low-intensity basketball exercise, the percentage of body fat of obese junior high school students after intervention was significantly higher than that before intervention [(32.16±2.26) % v.s. (34.33±2.35) %] ( t = 3.52, P<0.05). There was no significant difference in other indexes body weight, body mass index, waist circumference, skeletal musclebetween before and after intervention ( t = 2.31, 1.98, 1.26, −1.65, P> 0. 05). For moderate-intensity basketball exercise group obdy weight, BMI, percentage of body fat and waist circumference showed statistical changes before and after intervention ( t = 3.44, 3.76, 6.56, 2.45, P<0.05). For high-intensity basketball exercise group, all body composition indicators showed significant changes ( t = 4.14, 5.18, 11.26, 5.89, −2.56, P<0.05).

          Conclusion Twelve weeks of basketball exercise can effectively improve body composition of obese junior middle school students, with higher the intensity of exercise, the better the effectiveness.


          【摘要】 目的 探讨不同强度篮球锻炼对肥胖初中生体成分的干预效果, 为肥胖初中生制定减肥降脂计划提供理论支 持。 方法 2020 年 9—11 月, 运用典型抽样法, 在武汉光谷实验中学抽取 48 名单纯性肥胖初中生为研究对象, 将其分为 大、中、小强度篮球训练组和对照组 (各 12 名), 对实验组进行为期 12 周, 3 次/周, 45 min/次不同运动强度的篮球锻炼干 预, 对照组不做干预, 并对干预前后体成分指标进行统计比较。 结果 经过 12 周小强度篮球锻炼后, 肥胖初中生体脂百分 比干预后 (32.16±2.26)%与干预前 (34.44±2.35)%相比差异有统计学意义 ( t = 3.52, P<0.05), 体重、BMI、腰围、骨骼肌干预 前后差异均无统计学意义 ( t 值分别为 2.31, 1.98, 1.26, −1.65, P 值均>0.05)。中强度篮球锻炼对肥胖初中生的体重、体质 量指数 (BMI)、体脂百分比和腰围在干预前后差异均有统计学意义 ( t 值分别为 3.44, 3.76, 6.56, 2.45, P 值均<0.05)。髙强 度篮球锻炼后, 所有指标干预前后差异均有统计学意义 ( t 值分别为 4.14, 5.18, 11.26, 5.89, −2.56, P 值均<0.05)。 结论 12 周篮球锻炼可以有效地改善肥胖初中生体成分的各项指标, 髙强度篮球锻炼的效果最好, 其次为中、小强度, 锻炼强度越大 效果越好。
