Abstract
To observe the effect of exercise intervention and nutrition health education on body composition and fitness of female college students with invisible obesity. 60 female college students with invisible obesity were randomly divided into three groups: control group, exercise intervention group and exercise + nutrition health education group. The control group had normal study and life; the exercise intervention group used aerobic exercise and resistance exercise to carry out collective exercise prescription exercise and individual contract exercise; the exercise intervention + nutrition health education group carried out nutrition health education on the basis of exercise intervention. Before the experiment, the three groups of female college students were homogenous (P > 0.05); after 16 weeks of the experiment, the body composition and fitness of the exercise intervention group and the exercise intervention + nutrition and health education group were significantly higher than that before the experiment, among which there were significant differences in BMI, BF%, VFI, vital capacity, 800m, sit forward flexion and sit up indexes (P < 0.05); after 8 weeks of training, the exercise intervention group was significantly higher than that before the experiment (P < 0.05) The BMI, BF% and VFI of the exercise intervention + nutrition health education group continued to decrease (P < 0.05). The combination of aerobic exercise and resistance exercise can reduce the body composition and improve the fitness level of female college students with recessive obesity. The effect of combined intervention of nutrition and health education on the basis of exercise intervention is better than that of single exercise intervention, and it can promote students to form the concept of reasonable nutrition and exercise actively. It is suggested that the correct nutrition concept and active exercise of the recessive obese college students can reduce the body composition and improve the fitness level of the recessive obese female college students.
Highlights
With the rapid development of economy and the technology, people’s diet and life in our country has changed a lot, for example, increased energy intake, unhealthy diet, sedentary lifestyle, and decreased physical activity
Recessive obesity, which means the body mass index (BMI) value is in the normal range, but the body fat percentage exceeds the limits, is ignored by most people.[4]
Body composition indicators: Subjects were required to fast 2 hours before the test, and the body mass index (BMI), body fat percentage (BF%), visceral fat index (VFI) and other indicators were measured by the body composition analyzer (In Body570, Korean) from 7:00 to 9:00
Summary
With the rapid development of economy and the technology, people’s diet and life in our country has changed a lot, for example, increased energy intake, unhealthy diet, sedentary lifestyle, and decreased physical activity. The rising rates of chronic noncommunicable diseases (such as obesity and high blood pressure) that are related to these changes, has become a severe threat to national health. According to The National Health Report of 2012,[1] The Nutrition and Chronic Disease Status Report of Chinese Residents (2015),[2] and relevant media reports,[3] the recessive obesity of Chinese women is becoming increasingly prominent. Further development may induce various cardiovascular and metabolic diseases such as hypertension, hyperlipidemia and fatty liver,[5] which seriously affects their physical and mental health. The results offer an effective way to control the recessive obesity of students in advance
