Effect of Resistance Training on Energy Intake and Appetite Regulation, 12-weeks Resistance Training

Resistance training is a common way of daily exercise which has a remarkable function in healthcare. It has been used in many diseases as a complementary method. Overweight and obesity are the sixth highest risk of death worldwide. In recent years, the data show that the rate of overweight obese among college students shows a significant increasing trend. The common characteristics of overweight and obese people are strong appetite which is difficult to be controled and sedentary. resistance training is a solid supplement to physical education and how to reduce appetite of overweight and obese college female students through resistance training is the key to increase their health by university sport course. The training plan divides the training intensity into three levels including 45-50% one repetition maximum(1RM), 60-65% 1RM, 45-50% 1RM, respectively plus control group. Therefore, this experimental research examines the effectiveness and the differences of three Intensities resistance training on energy intake and appetite regulation among overweight and obese college girl. Finally, to evaluate whether the resistance training can reduce the overweight and obese female college students' energy intake and appetite regulation

On the basis of consulting relevant literature, this paper designs a 12 week teaching plan of resistance training through experimental design and quantitative research methods, combined with the characteristics of resistance training and the physiological characteristics of obese or overweight people. The purpose of this experiment is to provide a theoretical basis for improving the teaching methods of College Students' physical education, so as to improve the energy intake and appetite regulation of obese and overweight female college students, and then reduce their weight. And compared with ordinary daily physical education courses. Among them, the experimental group was divided into three groups, and the resistance training with intensity of 45-50% 1RM, 60-65% 1RM and 80-85% 1RM was carried out respectively. The control group carried out daily physical education teaching content. The number of participating samples in each group is 18 overweight or obese female college students, and the samples in each group are located in different campuses.

The first section of the training program of the experimental groups are warm up (10 mins) which including two parts. The first part is jogging and running indoor or stationary cycling outdoor with low intensity (5 minutes), the second part is muscle stretching: the Chinese eight set of radio kinetics (each movement 8 times) including stretch exercise, check augmentation exercise, kicking exercise, body side exercise, body rotation exercise, whole body exercise, jump exercise, cooling down exercise Then, the main resistance training section of the experimental group includes test press, late pull down, shoulder press, square, leg extension, leg curl, bicep curl, triceps extension, dominant crunches, lower back exercises In the last cool down phase, repeat the same content of muscle stretching as in the first part again.

Three times a week, with an interval of more than 48 hours. Each exercise of main resistance training takes 2 sets, and the repetition times of low intensity, medium intensity and high intensity are 16-18 times, 10-12 times and 6-8 times respectively. The rest time between low-intensity, medium-intensity and high-intensity groups is 1 minute, 1-2 minutes and 2-3 minutes respectively. The total duration of each training is about 1 hour, including warm up for about 10 minutes, main training time for about 45 minutes, and final cool down for about 5 minutes. In addition, the maximum strength was retested once at week 1, 5 and 9 respectively The control group only changed the resistance training part to normal P.E. course which carried out general teaching content according to the college syllabus, other settings are the same.
