【摘要】：研究目的:本研究针对肥胖儿童创编了一套肥胖少儿哑铃操,并通过实验测得其运动负荷并验证其减肥效果,目的是为肥胖儿童制定一个合理的锻炼方式,塑造其体形并充实其校园生活。研究方法:本研究采用文献资料法、实验法、问卷调查法和数理统计法,本着趣味性、针对性、运动适宜等原则,依据儿童少年的身心发展特点进行创编。在珠海市香洲区第七实验小学招募10名单纯性肥胖少儿10~11岁(4~5年级),5男5女,实验时间是2016年4月~5月。实验包括两部分:运动负荷测试和训练效果实验。其中运动负荷包括运动强度和运动量,本实验选取心率(HR)、主观疲劳感(RPE)、血乳酸(BLA)、肌酸激酶(CK)、尿蛋白(PRO)作为监控运动强度的指标,用血尿素(BU)、尿胆原(URO)作为监控运动量的指标(其中HR和RPE是生理指标)。其次是训练效果实验:4周训练,测试的指标有身高、体重和体脂。研究结果:(1)学生调查问卷显示喜欢这套哑铃操的学生超过80.00%,70.00%的学生觉得难易适中,感觉不太累和一般的学生占75.00%,97.50%的学生愿意接受哑铃操的学习90.00%的学生觉得自己掌握的情况好,85.00%的学生觉得这套哑铃操安全。(2)教师调查问卷显示,75.00%的教师认为这套操音乐速度适中适合编排哑铃操且编排合理,超过65.00%的教师认为动作内容具有多样性,音乐与动作协调统一,具有趣味性和安全性,85.00%的教师认为运动强度合适。(3)运动负荷测试测得这套哑铃操的平均心率为134±9.73b/min,心率区间为120~160b/min;运动后测得RPE的平均值为12.10±1.65;三次测试血乳酸的均值呈上升趋势;肌酸激酶呈上升趋势;运动后70%的受试者尿蛋白(PRO)呈阴性,尿胆原(URO)无明显变化;血尿素三次测试的均值呈上升趋势。(4)训练效果试验:4周训练前后受试者BMI有明显下降趋势(P0.05),具有统计学意义;体脂率有下降趋势(P0.05),但无统计学意义。研究结论:(1)这套少儿哑铃操音乐节奏动感清晰,动作内容丰富、难度适中,运动强度合适,编排富有创新性和趣味性受到教师们的一致肯定和小学生们的喜爱,受试者学习积极性高,掌握情况良好。(2)从心率和血乳酸数据分析可以看出这套少儿哑铃操属于中等强度的有氧运动,分析RPE、血乳酸、尿蛋白、CK可以得出这套少儿哑铃操属于中低等强度的运动,分析血尿素、尿胆原、CK和尿蛋白数据可以得出少儿哑铃操运动量适中。(3)这套哑铃操有一定的减肥效果,其中受试者的体重和BMI下降,具有统计学意义(P0.05);体脂也呈下降趋势,但无统计学意义(P0.05)。
[Abstract]:Objective: this study designed a set of obese children's dumbbell exercises for obese children, measured their exercise load and verified their weight loss effects through experiments, in order to establish a reasonable exercise mode for obese children. Shape it and enrich its campus life. Methods: this study adopts the methods of literature, experiment, questionnaire and mathematical statistics, based on the principles of interest, pertinence and fitness, according to the characteristics of children and adolescents' physical and mental development. Ten children with simple obesity were recruited from the 7th Experimental Primary School of Xiangzhou District, Zhuhai City. The experimental time was from April to May 2016. The experiment consists of two parts: exercise load test and training effect experiment. The exercise load included exercise intensity and exercise volume. In this experiment, heart rate (HRV), subjective fatigue (RPE), blood lactic acid (lactic acid) BLAA, creatine kinase (CK), urinary protein (PROP) were selected as indicators to monitor exercise intensity. Blood urea bun and uro were used as indicators to monitor exercise volume (HR and RPE were physiological indexes). The second is the training effect experiment: 4 weeks training. The indexes are height, weight and body fat. Research results: 1) A student questionnaire shows that more than 80. 00% of students who like this set of dumbbell exercises find it easy to moderate. Students who feel not too tired and average students account for 75.00% of students are willing to learn dumbbell exercises 90.00% of students feel that they have a good grasp of the situation 85.00% of students think the dumbbell exercises are safe. 2) the teacher questionnaire shows that 75.00% of teachers think this set of exercises is safe. Moderate music speed is suitable for arranging dumbbell exercises and arranging them reasonably. More than 65.00% of teachers think that the content of action is diverse, and the music and movement are coordinated and unified. 85.00% of the teachers thought that the exercise intensity was suitable. 3) the average heart rate of the dumbbell exercise was 134 卤9.73 b / min and the heart rate interval was 120 ~ 160 b / min, the mean value of RPE after exercise was 12.10 卤1.65. Creatine kinase showed an upward trend, 70% of the subjects showed negative proteinuria after exercise, but there was no obvious change in uro. The mean value of blood urea trimester showed an increasing trend.) the BMI of subjects before and after 4 weeks training showed a significant decrease trend (P 0.05), and the body fat rate had a decreasing trend (P 0.05), but no statistical significance. Conclusion: (1) this set of children's dumbbell exercises has a clear rhythm, rich content, moderate difficulty, appropriate intensity of movement, and the creative and interesting arrangement has been unanimously affirmed by teachers and loved by pupils. From the analysis of heart rate and blood lactic acid data, we can see that this set of children dumbbell exercise belongs to moderate intensity aerobic exercise, analysis of RPE, blood lactic acid, This set of children's dumbbell exercises can be obtained by analyzing blood urea, urine gallstone CK and urine protein data. It can be concluded that the children's dumbbell exercises have moderate exercise amount. 3) this set of dumbbell exercises has certain weight loss effect. The body weight and BMI of the subjects decreased with statistical significance (P 0.05), and the body fat also showed a decreasing trend, but there was no significant difference in body fat (P 0.05).
