This study has examined the effect of after-school physical activity on body composition and health related fitness of middle school students. The duration of after-school physical activity training program of this study is 12 weeks, the training time in 1 hours warming-up 10 minutes, the skill training 45 minutes and cool down did in 5 minutes. Exercise frequency is 5 time per week. Height basketball class, soccer class, subject class showed statistically meaningful increase between group variance showed statistically meaningful. Weight basketball class, soccer class, showed statistically meaningful decrease. Muscle mass basketball class showed statistically meaningful increase, soccer class showed statistically meaningful decrease. Cardiopulmonary basketball class, soccer class, showed statistically meaningful decrease. Explosive muscular strength basketball class, soccer class, showed statistically meaningful decrease. subject class showed statistically meaningful increase, between group variance showed statistically meaningful. Flexibility basketball class showed statistically meaningful increase, soccer class. Muscular strength basketball class, soccer class, subject class showed not statistically meaningful different.

The aim of this study was to examine the effects of an after-school basketball training program of 12 weeks on physical abilities (grip strength, endurance, and flexibility) and learning-related factors (cognition strength, cognition speed, concentration, and mental workload) in middle school students. Middle school students (Males, N=20) were recruited for use in this study and were randomly divided into either a basketball training group (n = 10, BT) or a non-exercise control group (n = 10, CON). Two-way repeated measures ANOVA with post-hoc testing was used for data analysis. Results found endurance and flexibility in the BT group were significantly increased, but not in the CON group. In addition, cognition strength, speed, and concentration in the BT group increased and mental workload in the BT group slightly decreased. In contrast, the CON group showed a significant increase in mental workload. Our findings show that participation in after-school physical education activities (e.g., basketball training program) positively improves physical abilities and increases brain functions for learning.

The purpose of this study was to investigate the effects of anterior cruciate ligament (ACL) injury prevention program on the ground reaction force during the rebound in female highschool basketball players. Sixteen highschool female basketball players (ages 16 to 18 years) were participated in this study. Eight of these players participated in a 8-week ACL injury prevention program. Before and After ACL injury prevention program, initial peak value(%BW), maximum peak value(%BW), impulse(%BW sec), and loading rate(N/sec) were measured in the players. The experiment group after ACL injury prevention program showed significant decreased initial peak value, impulse, and loading rate.

The main purpose of this thesis was to provide a basis to investigate the effectiveness of regular exercises on basic physical fitness for middle school students. 40 second graders from a middle school were chosen randomly and divided into 4 groups-wrestling group, basketball group, jogging group, and control group. The first three groups have been trained 4 times per week for 18 weeks after class to be compared with the comparison group. Pre and post measurements of physical fitness of the subjects were processed by means of the SPSS program. The average and the standard deviation of the measurements of each group were covered with the ANOVA test, according to the periods and the types of training. Duncan's Multiple Range Test was performed to identify the significance of the relationship between training period and improvement in basic sports ability. The conclusions as follows; 1. In the 50 meter sprint, only the wrestling group showed statistical significance, while the other groups showed gradual progress in general. 2. In the standing long jump, there is no group that showed any improvement. 3. In the forward flexion of the trunk, no significance was to be found. 4. In 30-second sit-ups, the wrestling group showed statistical significance. The wrestling group made greater progress than the other groups, and the basketball group and the jogging group also showed rather great progress. 5. In push-ups, statistical significance was found in the groups of wrestling, basketball, and jogging. And the wrestling group came in first, the basketball group second, and the jogging group third on the progress level. 6. In the distance run, the jogging group showed statistical significance and the jogging group made considerable progress. Steady improvement was to be found in the groups of wrestling and basketball.

The purpose of this study was to find out the effects of aerobic training plus diet on blood lipids and apolipoproteins (Apo) in obese children. Sixteen healthy obese boys (ages 10.9; body mass index (BMI) $\geq$95th percentiles for age and sex) participated in this study. The aerobic training program consisted of 40 minutes hiking on a mountain, 60 minute of basketball and football dribbling at an intensity of 60-70% of HRmax, and was performed 5 days a week for 9 weeks. The diet prescription was 2,100 kal/day according to the recommended dietary allowance for 10-12 year old Koreans. All subjects stayed in a training camp for 9 weeks. The results of this study were as follows; Blood lipid profiles including total cholesterol (TC), triglyceride (TG) high density lipoprotein cholesterol (HDL-C) and TC/HDL-C ratio were significantly improved after the 9 week program, but there was no significant change in low density lipoprotein (LDL-C). Apolipoprotein profiles, Apo AI, AII, B, CII and CⅢ were all significantly decreased after the 9 week program, but there were no significant difference in Apo AI/AII ratio and Apo B/AI ratio. These results indicate that aerobic training together with a healthy diet can induce positive changes on blood lipid profiles, Apo AII, B and CII in obese children.

The purpose on this study identified the purchasing conditions of Sports wear of the Chinese men residing in Beijing, Shanghai, Dalian, Tianjin, Harbin and Guangzhou, so that it helped sports wear manufacturers and retailers offer the basic data. For the study, a questionnaire used as a method of measurement, the 863 Chinese men were selected as a sample, SAS(Statistical Analysis System) program was used to analyze the data. The results from the study were as follows: 1. According to the investigation, the most preferred sports of Chinese men is soccer, as a whole. Swimming, basketball and ping-pong keep rank the next to soccer. 2. Accordingly age, area, profession and income, Chinese men maintained sports suit in order of training suit, swimming suit, soccer suit, tennis suit. It is found that holding amount of high-quality sports wears as ski, golf is on a low level. 3. It is appeared that Chinese men purchased in good order as follow brand: No-bran, Nike, Lening, Adidas. And except Nike, they purchased more Lening brand than foreign sports brand. 4. As the result of researching on the item of sports wear, it is found that they purchased various kind items in a higher rank 5 brands. 5. Sports wear's color that Chinese men purchased is blue, white, black, red. 6. The purchasing price that Chinese men favored is 200$\sim$599RMB. Thus, they expend average per head for sports suit buying, 486.0RMB. 7. Chinese men purchased very often at specialty store. And, coefficient of utilization at the usual market is on a low level. 8. In purchasing satisfaction, 80 % Chinese men were satisfied with goods(sports wear) that purchased in a higher rank 5 brands. So, average satisfaction degree showed over 3.8 as a high rate. 9. According to the result of satisfaction on Chinese men, 70% Chinese men showed satisfaction. Therefore, the average of satisfaction degree appeared 3.81 as a high rate.
