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.

이 연구는 12주간 중학교 남학생의 방과 후 농구 훈련 프로그램 참여가 신체활동능력(심폐지구력, 유연성, 근력) 및 학습관련요인(인지강도, 인지속도, 집중력, 작업부하도)에 어떠한 영향을 주는지에 대하여 규명 하고자 총 20명의 참가자가 운동참여집단(10명)과 통제집단(10명)으로 나뉘었다. 본 연구의 통분석은 반복측정분산분석(Repeated Measure ANOVA)을 실시하고, 모든 자료의 유의수준은 ${\alpha}=.05$로 설정하였다. 분석한 결과 신체활동능력 변인 중 운동집단의 심폐지구력과 유연성은 통계적으로 유의하게 증가하였다. 그러나 운동집단의 악력은 통계적으로 유의하지는 않지만 증가하는 경향을 보였다. 학습관련요인 변인 중 운동집단의 인지강도, 인지속도, 집중력은 통계적으로 유의하지는 않으나 증가하는 경향을 보였고, 통제집단의 작업부하도는 통계적으로 유의하게 증가하였다. 이상의 결과를 종합해보면 방과 후 농구 훈련 프로그램의 참여는 중학생의 신체적인 성장과 발달과 학업성취도 측면에 긍정적인 영향을 줄 수 있을 것이라고 생각된다.

본 연구는 8주간의 전방십자인대 손상예방훈련이 농구 리바운드 점프 후 착지 시 지면반력에 미치는 영향을 규명하는 것이다. 본 연구에 참가한 연구 대상자는 $16{\sim}18$세 사이의 여자 농구선수 16명이다. 8주간의 전방십자인대 손상예방훈련을 수행할 실험집단 8명과 스포츠상해 예방훈련을 수행하지 않을 통제집단 8명을 무작위로 나눈 후 훈련 전후에 농구 리바운드 점프 후 착지 시 초기피크(%BW), 최대피크(%BW), 충격량(%BW.sec) 및 부하율 (N/sec)을 산출하였다. 본 연구 결과 농구 리바운드 점프 후 착지 시에 8주간의 전방십자인대 손상예방훈련을 받은 실험집단에서 초기피크 값이 감소하였다. 또한, 실험집단에서 지면반력의 충격량과 부하율이 유의하게 감소한 것으로 나타났다. 이는 8주간의 전방십자인대 손상예방 프로그램이 점프 동작에 필요한 하지의 근신경 조직에 유의한 긍정적 영향을 미쳐 효율적으로 착지한 것으로 판단된다.

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.

비만 남자 초등학생을 대상으로 식사 조절과 병행한 유산 소운동을 HRmax의 60-70% 강도로 1일 100분, 주 5회, 9주간 실시하여 이들의 혈중지질과 아포지단백에 미치는 효과에 대해 알아보았다. 혈중지질의 TC, TG, HDL-C 농도와 TC/ HDL-C비가 개선되었는데 이는 규칙적인 유산소운동과 에너지섭취량 제한(식사제한)이 아닌 1일 영양권장량에 준하는 정상적인 에너지 섭취를 통해 비만아동의 체중감량과 더불어 CHD 위험인자인 혈중지질에 긍정적인 효과를 미칠 수 있음을 확인하였다. 또한 아포지단백의 Apo AII, B, CIII 농도가 감소하였는데 이는 유산소운동과 식사조절 병행이 성인의 경우와 유사하게 비만 남자아동들에게도 동맥경화 질환의 예방에 효과적인 방법이 될 수 있음을 증명하는 결과로 사료된다. 그렇지만 아직 운동에 따른 Apo 반응에 대한 연구들이 미흡하고 특히 Apo CII와 CIII에 대한 연구는 더욱 미흡한 상황이므로 향후 이에 관련된 후속 연구가 진행되어야할 것으로 생각된다.
