The purpose of this study was to compare somatotype of lower extremity and its relationship with leg extension power on 108 players in 8 different types of sports(boxing, judo, taekwondo, golf, volleyball, handball, rugby, badminton).The research method : Body composition test was measured in % body fat, lean body mass by inbody 3.0 of bioelectrical impedance analysis. Somatotype test was measured in leg length, thigh length, calf length, thigh girth, calf girth, abdominal girth and bultocks girth by steel tape and skinfold caliper. Leg extension power test was measured by Anaeropress 3500. The data was analyzed using discriminant on SPSS(Version 11.0) statistical package. The statistical methods utilized in this study were one-way ANOVA, correlation analysis and regression analysis. For all tests, alpha was set at .05 initially in significance.The results were as follows. Handball and volleyball players were significantly long in length of total lower extremity, calf, and thigh. Rugby and judo players were significantly wide in girth. Leg extension total power and relative value to body weight were significantly high in judo, badminton, volleyball. Speed factor was significantly high in judo, badminton, volleyball and force factor was significantly high in handball, boxing, golf, rugby, volleyball. There were various relationship between power and somatotype of lower extremity factors according to types of sports, especially with girth. Speed factor and force factor also have great relationship with girth.These findings support the idea that according to types of sports, there were various relationship between power and somatotype of lower extremity factors. Therefore, in strength training according to type of sports, various rate of speed and strength power weight training program must be proposed.

The purpose of this study was to compare body composition, physical strength and V02max between kindergatener and sports kindergatener. The subjects were 5 years old infants(n=68) who were lived in same area. They were divided into two groups as kindergatener(n=35) and sports kindergatener(n=33) who attended to sports kindergarten which has professional physical education program more than a year.The results were as follows.Fist, on physique, height, weight, LBM and BMI were higher and percent body fat was lower in both gender of sports kindergatener but there was no significant difference.Second, on physical Strength, back strength, standing long jump, 5m shuttle run and sit trunk flexion were higher in sports kindergatener but there was no significant difference. one foot balance and sit-up were higher in both gender of sports kindergatener and there was a significant difference.Third, on cardiopulmonary functions, V02max was higher in both gender of sports kindergatener but there was no significant difference.Consequently, sports kindergartener who were educated professional physical education program has highly physical strength and well-grown. Especially, on balance and muscle endurance were significantly high. It could be helpful on elevation of health basic physical strength. Accordingly, to maximize growing of physique and physical strength, proper progressive physical education program must be educated and infant physical education time must be prolonged. And standards to valuate infant physique and physical strength must be set.

This study was investigated to demonstrate the efficient hypobaric & hypoxic training type. After the long-term training period, oxygen uptake during the submaximal and maximal treadmill incremental exercise, oxygen transport ability of the blood, and effects on game record among groups were compared and analyzed. 23 male and female high school elite runners were divided into two experimental groups and one control group according to training types. That was, 1) living high training high(H.H) group(n=8) which were training at 2,000m and sleeping at 3,000m. 2) living high training sea level(HS) group(n=8) which were training at sea level and sleeping at 3,000m 3) living and training sea level(S.S) group(n=7) which were training and sleeping at sea level, control group. After 5~6 weeks training(70% maximal oxygen uptake(VO2max) four times/wk) and sleeping(8hr/day), oxygen uptake(by treadmill graded submaximal and maximal exercise test), oxygen transporting capacity and effects on time records were investigated. Results were as follows. 1. There was no significant difference on body composition according to training types or test time. 2. During graded submaximal exercise tests, heart rate and blood lactate concentration was significantly low but there was no significant difference according to training types or test time. During graded submaximal exercise tests, maximal oxygen uptake was high but there was no significant difference according to training types or test time. 3. There was no significant difference on red blood cell(RBC), hematocrit(Hct), hemoglobin(Hb) concentration according to training period increase or training types or test time. In the incipient stage, erythropoietin(EPO) was significantly increased, but 2,3-diphosphoglycerate(DPG) was significantly decreased. In the last stage, EPO was changed a little, but 2,3-DPG was significantly increased. 4. In hypobaric hvpoxic environment, heart rate was decrease as time goes by. Especially during sleeping, there was significantly decrease after 3 weeks. 5. Ten-kilometer time were improved in H.H group and S.S group and there was a significant difference according to covariates. As a result, active hypobaric hypoxic acclimation is not more efficient than passive acclimation to aerobic performance.

이 연구는 성인의 연령에 따른 건강생활습관(운동, 흡연, 음주), 신체구성, 혈압 및 체력요인의 차이와 상관성을 알아보기 위해 2006년 7월 충주지역에서 개최된 건강 운동처방 교실에 참가한 257명을 대상으로 한 문진검사로 운동, 흡연, 음주 등을 조사하였으며, 신체구성, 혈압 및 체력을 측정한 결과를 요약하면, 1. 연령증가에 따른 신장은 유의하게 감소하였으며, 복부지방율은 유의하게 증가하였다. 또한, 남자는 제지방량의 감소로 체중이 감소하였으나, 여자는 체지방율의 유의한 증가로 체중이 유의하게 증가하였다. 2. 연령증가에 따른 혈압은 유의하게 증가하여 남자 60대와 여자 50대에서 높아졌으며, 안정 시 심박수는 연령증가에 따라 여자가 유의하게 높았다. 3. 연령증가에 따른 체력은 남녀 모두 유의하게 감소하였으며, 여자는 좌전굴을 제외하고 남자보다 낮았다. 4. 운동, 흡연, 음주 등에 40대가 가장 높은 빈도를 나타났으며, 운동량은 30대, 흡연량은 50대, 음주량은 20대에서 가장 높았다. 5. 연령과 운동은 체력요인과 각각 음과 양의 유의한 상관성이 나타났으며, 흡연은 심박수의 증가와 유의한 상관성이 나타났다. 또한, 음주는 근력, 근지구력, 순발력, 심폐기능의 저하와 유의한 상관관계를 나타냈다. The purpose of this study was to investigate the relationships between health behavior and body composition, blood pressure and physical strength. Exercise, smoking, drinking habits were investigated by questionnaire and body composition, blood pressure, physical strength were investigated by measuring in 257 subjects. The results were as follows. First, height was significantly decreased, but WHR was significantly increased with age. Second, blood pressure was significantly increased with age. Rest heart rate was significantly increased in female with age. Third, physical strength was significantly decreased with age. Forth, exercise, smoking, drinking were showed highest frequency those who in their forties. Exercise index was highest those in their thirties, smoking index was highest those in their fifties and drinking index was highest those in their twenties. Fifth, age was showed significant de-correlation with physical strength factors. And exercise was showed significant correlation with physical strength factors.
