Effect Of Simple Obesity Adolescents Exercise Intervention

【Objective】 At the same time of improve people’s quality of life, simple obesity has become a serious threat to human health hazards in the 21 st century. Today, some developing countries, especially in Asia and even the number of Pacific island countries, obesity rates of cancer are also rose sharply, which is especially adolescent obesity, they will constitute the main part of the obese people, accordingly, these will be a risk factor and hidden in people’s physical fitness. In recent years, the problem of obesity research has gradually attracted people’s attention, but the research on simple obesity more concentrated in the general aerobics exercise intervention for obesity, ignoring the development of new and interesting exercise intervention method. Under the premise of this research in aerobic exercise, anaerobic exercise, development of new and interesting exercise intervention methods, formulated for 12 weeks of exercise intervention method, the youngsters are groups of simple obesity in test before and after the body shape, body composition, physical quality, the change of the index such as body function to do a discussion, and not to participate in exercise intervention group simple obesity adolescents for comparative analysis, in order to simple obese adolescents exercise intervention methods provide new ideas and methods.【Method】 This study according to our country in 2004 to determine the "Chinese school-age children and adolescents overweight and obese BMI screening classification standard", the Shanghai youth vocational college five-year higher vocational level of 2013 and 2014, students aged 15 to 18 one full year of life, height and weight measurement, preliminary screening out the object of study. Ultimately determine the simple obesity adolescents, a total of 32, it can be divided into obesity group of 16 people(male 8, female 8) and obese control group 16 people(male 8, female 8). The movement of 16 obese students exercise intervention for 12 weeks. While the control group in addition to normal physical education, not for any other sports. Before and after the experiment through to the subjects’ body shape, body composition, physical quality, body function changes of the indicators such as detailed collection, analysis and comparison, reveal the effect of simple obesity adolescents exercise intervention.【Results】 1. In the aspects of body shape: after 12 weeks, upper arm kinfolks reduce obesity exercise group, control group and obesity of upper arm kinfolks significantly increased(boys: exercise group △= 2.83 mm, the control group △= 4.31 mm; female: exercise group △= 2.76 mm, control group △= 3.44 mm). Back kinfolks reduce obesity exercise group, control group and obesity back has also increased the kinfolks(girl: exercise group △= 2.49 mm, the control group △= 4.78 mm; boys: exercise group △= 3.39 mm, control group △= 1.11 mm). Abdominal kinfolks also reduce obesity exercise group, control group and obesity significantly increased abdominal kinfolks(girl: exercise group △= 3.49 mm, the control group △= 7.06 mm; boys: exercise group △= 1.23 mm, control group △= 5.23 mm). Two groups of boys in addition to hip circumference before and after the experiment, general no significant changes in body surround degree, with increase of physical development hip circumference instead(exercise group △= 2.2 cm, the control group △= 2.26 cm). Obesity group of girls waist circumference, hip circumference after 12 weeks ago had no obvious change, and the chest reduced(△= 2.6 cm), waist hip ratio(△= 0.03 cm). Obesity control girl’s waist circumference, waist-hip ratio, there was no significant difference before and after the experiment, and the chest increased(△= 4.39 cm), has also increased the hip circumference(△= 2.03 cm).2. In the aspect of body composition: obesity group of boys after 12 weeks of exercise intervention, increased muscle weight, BMR(△= 2.34 kg, △= 69.1 cal), fat(△= 2.01 kg) reduction in weight, body fat percentage decrease(△= 2.85%), obesity, reduce(△= 3.87%), BMI than before the experiment to reduce(△= 0.55 kg/m2); After 12 weeks of exercise intervention, obesity group of girls muscle weight increase(△= 0.62 kg), BMR(△= 18.61 cal), fat(△= 1.86 kg) reduction in weight, body fat percentage decrease(△= 2.2%), obesity(△= 3.6%), BMI decrease(△= 0.68 kg/m2).After 12 weeks, obese control group boys weight(△= 3.52 kg) of weight, fat weight increase(△= 8.07 kg), obesity lengthened(△= 5.78%), increased BMI(△= 1.24 kg/m2), compared with the experiment very significant changes have taken place before P < 0.01, and the body fat percentage increase(△= 1.45%) and significant differences P < 0.05, while the muscle weight, BMR also have different degrees of growth, but there is no significant change before and after the experiment(P > 0.05); After 12 weeks, obese control group girls body composition of the indicators compared with 12 weeks ago showed no significant difference(P > 0.05).3. In terms of physical quality, sports can comprehensively improve the obese body quality, especially represented by standing long jump of the power quality has obvious increase than the control group(boys: sports group △= 254 cm, the control group △= 162 cm; girls: exercise group △= 217 cm, the control group △= 147 cm), and cardiopulmonary endurance also had significantly improved compared with control subjects(male 1000 meters: the control group grades 1.1 min ahead of time, exercise group grade 2 min in advance; girl 800 meters: the control result 0.8 min ahead of time, exercise group 1.6 min) in advance.4. In terms of body function, both in obesity group and obesity lung capacity in the control group showed increasing trend, the difference is vital capacity growth to exercise group was obviously higher than that of control group(boys: sports group △= 450 ml, the control group △= 206 ml, girls: exercise group △= 330 ml, control group △= 154 ml)【Conclusion】 1. Exercise intervention on the body shape plays an active role in obese adolescents. 12 weeks of exercise intervention effect on obese adolescents between men and women kinfolks evident, characterized by kinfolks are reduced. To female obese teens at the same time the influence of body shape but also in the body is surrounded and waist-to-hip ratio are reduced.2. Exercise intervention has a positive effect on simple obesity adolescent body composition, mainly embodied in lean body mass, body fat percentage decrease, BMI value decreases, and obesity, and to prevent obesity continues to increase. Male simple obese adolescents more focuses on the growth of lean body mass.3. The exercise intervention for obese students physical quality influence tends to be beneficial directions, especially the power quality and cardiopulmonary endurance quality is more outstanding, and boys range to improve the quality of the body movement is bigger than girls.4. The influence of the body function of exercise intervention for obese students is positive, both boys and girls, vital capacity increased overall.Innovative: this research combining the physical stamina training concept, on the premise of aerobic exercise, combined with the HIIT, development of new, interesting and accord with the characteristics of adolescent growth and development regularity and mental exercise intervention method. And in the exercise group and control group before and after the experiment of body shape, body function and body composition, physical quality index is evaluated, and verify the effectiveness of intervention. To form a specific obese adolescents exercise intervention plan, exercise for weight loss and the fertilizer for the young people new ideas and methods.
