본 연구의 목적은 성장기 어린이의 지속적 태권도 수련이 건강체력요인과 신체적 자기 개념에 어떠한 변화 가져오는가를 규명하고 더불어 국기 스포츠인 태권도 수련에 혜택을 규명함에 그 목적이 있다고 할 수 있다. 연구대상자는 서울 소재 K 초등학교에 재학중인 남녀 초등학생 45명(수련집단 23명, 비수련집단 22명)을 대상으로 실시하였으며, 연구대상자는 주4회, 1회 지속시간 약 50-60분의 태권도 수련에 참가하였다. 본 연구의 종속변인으로는 체력요인과 신체적자기개념으로 설정하였고, 이에 기준선, 6주 12주 총3회 자료가 수집되었으며, 실험설계는 2개의 집단과 3개의 측정시점으로 구성되는 2×3 반복측정에 의한 요인설계(2×3 Factorial Design with Repeated-measures)를 이용하였다. 일련의 연구절차를 통하여 도출된 결과는 다음과 같다. 먼저, 초등학생이 태권도 수련은 윗몸일으키기, 눈감고외발서기, 좌전굴, 제자리멀리뛰기의 체력 요인에 긍정적 효과가 나타났으며, 신체적자기개념의 결과에서는 외모, 신체활동, 유연성, 건강, 자기존중감, 지구력, 신체전반의 하위요인에서 통계적 유의한 효과가 인정되었다.

The purpose of this study is to find out the subjective and objective fatigue level and the characteristics of seamen's physical strength with the service period on board, to have a new understanding of the vocation, and to explore a physical exercising program for the seamen. The questionnaire survey for the seamen who had been in service on the ocean going vessels was conducted and the results are fumed out as the followings. Total number of seamen who had answered the questionnaire was 64 persons and the distribution status of service period group was identified as 16 persons for each of 4 groups； the group was classified as the group of less than 5 years, 5 - 10 years, 10 - 15 years, and more than 15 years. 1. Working conditions Working hours in a week was identified as 44－56 hours(45.3%) and the number of 45.3% of the seamen answered the working hours in week is more than 56 hours. The seamen of 25.0% are unsatisfied or very unsatisfied with their vocation. The seamen of 65.6% are smoking, and 45.3% of them drink. The seamen of 44.,3% drink once or more in a week. And the seamen of 67.2% do not take any exercise in a week. 2. Contribution to the seamen's fatigue and subjective symptom The most contributive factor to the seamen's fatigue was identified as the short of sleeping(21.5%), overwork(19.2%), poor working conditions (18.6%), and the friction in human relations also becomes one the contribution to the fatigue(14.0%). The subjective symptom by fatigue was identified as the feeling of languid, sleepy and tiredness of eyes. 3. Characteristics of the seamen's physical strength and Interrelations The grip strength and back strength of the seamen whose service period is less than 5 years were measured as 40.44kg and 127.8kg. The sit ups in the group of service period less than 5 years was measured as 36.84 times, and the vertical jump for the seamen in this group was measured as 46.55cm. The closed-eyes foot balance was measured as 33.64 seconds in the group of service period between 5 and 10 years, and side-step was measured as 35.31 times in the group of service period less than 5 years. The standing trunk flexion was measured as 10.54cm for the seamen whose service period is between 10-15 years, and the trunk extension was measured as 50.70cm for the seamen whose service period is less than 5 years. And the step test of the seamen whose service period is between 10-15 years was measured as 54.44 numbers, and the number of flickers of the seamen whose service period is less than 5 years was measured as 32.94.

마늘분말을 mouse에 체중 kg당 2,000mg의 고용량군과 200mg의 저용량군으로 설정하고 대조군에는 증류수만을 투여하고 모든 시험군에서 시료를 매일 지정된 농도로 10일간 경구투여한 후 11일째 시험한 결과 마늘분말 투여군이 대조군보다 유의성(p〈0.05)있는 수영능력을 나타냈으며, 각군에 대한 체중변화는 전혀 관찰되지 않았다. 또 수영능력후 사망한 mouse에 대한 부검에서 마늘분말의 투여에 의한 병리학적인 현상은 전혀 관찰되지 않았다.
