Inadequate nutritional status of iron could interfere with normal growth and might impair physical performance among the physically active athletes. We examined the dietary intake and iron intake profiles in male high school gymnasts. Age of the subjects ranged from 15 to 17y at the time of the experiment. Most of subjects consumed nutrients at levels less than 2/3 of the RDA for the Korean adolescent, except for vitamin C and phosphous. The mean value of energy and iron intake were 1919.6±468.58 kcal(75.4±25.91% of the RDA) and 11.8±4.98 mg(64.7±28.1 7.8% of the RDA). Thus, it seems clear that maintaining good iron nutritional status could protect iron-deficiency anemia and improve the exercise performance ability and athletic power. We suggest that adequate food and nutrient intakes, especially iron, might help to maintain exercise ability in female gymnasts.

이 연구는 장기간의 태권도 수련이 최대산소섭취능력(maximal O₂ uptake, VO₂max)과 무산소성역치(anaerobic threshold, AT), 심근산소소비량(myocardial oxygen uptake, MVO₂), 심전도상 V? ST분절 및 QRS간격에 어떠한 영향을 미치는지를 규명하는 데 있다. 이를 위해 태권도를 5년 이상 규칙적으로 수련해 온 대학교 여자태권도선수(11명)와 체육학과 여자 비선수(10명)를 대상으로 운동부하 검사(balke protocol)를 실시하여 이들 두 집단 간 최대산소섭취량과 무산소성역치수준, 심전도를 통한 ST분절과 QRS간격을 동시에 분석하였다. 측정된 자료는 평균과 표준편차로 나타냈으며 또한 대응표본 t -test로 유의성 검사를 하였다. 그 결과 최대산소섭취량은 태권도선수집단이 대조집단에 비해 높게 나타났으며(p<0.01), 무산소성역치수준도 태권도선수집단이 유의하게 높게 나타났다(p<0.05). 안정시 및 최대운동시 심근산소소비량은 두 집단 간 통계적인 차이가 없었다. 심전도 ST분절의 경우는 두 집단 간 차이가 발견되지 않았으나, 안정시 QRS간격은 태권도선수집단에서 유의하게 길게 나타났다(p<0.01). 결론적으로, 규칙적인 태권도 수련은 유산소성 능력을 강화시켜주고 안정시 심박수의 감소를 가져오는 것으로 사료된다. The purpose of this study was to investigate the effects of taekwondo training on VO₂max, MVO₂ and electrocardiogram ST slope, QRS duration in college woman. Subject were divided into two groups, one is taekwondo group (n=11) and the other is control group (n=10). They participated in graded exercise test (Balke protocol) and measured aerobic capacity and electrocardiogram. The aerobic capacity (VO₂max and AT) was measured by autogas analyser. The resting and exercise rate-pressure product (RPP) could be measured with HR and systolic BP for MVO₂ measurement. The electrocardiogram ST slope, QRS duration was calculated using automated software program (QMC). The measured data were analyzed by using paired t -test. The results of this study were as follows : There was a significant difference of VO₂max and AT between taekwondo group and control group. VO₂max of taekwondo group was 4~5 mL/㎏/min higher than control group (p<0.01) and AT also taekwondo group was 3.4% higher than control group (p<0.05). There was no significant difference of maximal exercise MVO₂ between taekwondo and control group. There was no significant difference of electrocardiogram ST slope between group but rest QRS duration in taekwondo group was longer than the control group (p<0.01). Conclusively, these data suggest that regular taekwondo training will strengthen on aerobic capacity and resting slow heart beats.

This study was performed to investigate the nutritional status, iron deficiency related blood parameters and immunoglobulin status of female soccer players. Twenty nine Korean national soccer players participated in the study. The mean age of the subjects was 22.1±2.6 years old. Their mean carrier as soccer player was 12.0±2.9 years. They were exercising regularly for 7.0±1.3 hr/day. Their mean height was 164.9±5.61 cm and mean weight was 53.5±4.81 kg. Mean iron intakes of the subjects was low (13.1±2.5 mg/d) and was 72.4% of Korean RDA. Most hematological iron indices were within normal range, except total iron binding capacity(TIBC) that was in the iron deficient range. When iron deficient group and normal group were separated by serum ferritin level(<10㎍/l or ≥10㎍/l), low ferritin group(n=8) had significantly lower hemoglobin, mean corpuscular volume(MCV), mean corpuscular hemoglobin(MCH), serum iron and ferritin levels and significantly higher TIBC than normal group(n=21). Immunoglobulin levels were within a normal range, and those values were not affected by low ferritin concentration.

The purpose of this study was to investigate the expression of the uncoupling protein-3 (UCP-3) mRNA on brown adipose tissue, tumor necrosis factor-a (TNF-α) mRNA on skeletal muscle, malondialdehyde (MDA) level on liver tissue in diabetic rats. Subjects were 24 diabetic rats. Experimental animals were randomly assigned to an exercise group (n=12) and non-exercise group (n=12). Moderate treadmill running (14~16 m/min on a 0% treadmill) applied for 30 minutes per session, 5 sessions per week, for 4 weeks. moderate treadmill exercise stimulus to diabetic experimental rats triggered significant group difference in the expression of UCP-3 mRNA on brown adipose tissue (p<.001) and TNF-α mRNA on skeletal muscle (p<.001). In spite of this kinds of group difference, there was no significant group difference in the level of MDA on liver tissue (p>.05). Therefore, this study suggests that the moderate exercise plays a critical role to regulate specific gene expression levels in adipose tissue and skeletal muscle of diabetic rats.

The purpose of this study was to investigate the eating patterns and weight control experience of Athletes. Subjects were 205 athletes of university (n = 77) and high school (n = 128) players whose age were average 17.4 years old and exercise experience were about 6 years. They were assigned to one of two conditions: (1) weight control group (Judo, Taekwondo etc.) and (2) weight non-control group (table tennis, tennis, badminton, and etc.). Results indicate that there were significant differences in the degree of training, fear of becoming obese, others` perception of their weight, coach`s order of weight control, coach`s weight record, thinking of weight, small amount of eating, and self-induced vomiting between the weight control and non-control group. However, there were no significant differences away the weight and performance, self-evaluation of weight, the change of weight, professional diagnose, and thinking of eating disorder, according to the group of weight control. These results might be useful in establish a basic database for determining the eating patterns and weight control status in some Korean athletes.

이 연구의 목적은 고령여성들에게 탄성저항운동과 단백질 보충제 섭취가 체구성, 기능적 체력, 노화과련 호르몬에 미치는 영향을 알아보기 위함이다. 65∼74세 노인여성 23명을 3집단으로 구분하였다(탄성저항운동+단백질보충제 섭취군, 탄성저항운동군, 대조군). 12주간의 탄성저항 운동은 주3회, 1회 60분으로 구성되었으며, 운동강도는 운동자각도 기준으로 12∼14 수준이었다. 단백질 보충제 섭취는 탄성저항 운동이 끝난 직후에 섭취하게 하였다. 모든 피험자는 12주간의 운동 전과 후에 체구성, 기능적 체력, 노화관련호르몬을 검사 받았고, 그 결과를 비교하였다. 통계분석을 통하여 다음과 같은 연구 결과를 얻었다. 골격근량은 탄성저항운동군+단백질보충제 섭취군에서만 통계적 유의하게 증가하였다. 기능적 체력검사 항목인 하체 근력, 상체 근력, 유산소 지구력, 하체 유연성, 상체 유연성, 민첩성과 동적 균형은 탄성저항운동군+단백질 섭취군과 탄성저항운동군에서 유의하게 증가한 것으로 나타났으며, 노화관련 호르몬인 에스트로겐과 성장호르몬은 2 집단(탄성저항운동+단백질보충제 섭취군, 탄성저항운동군에서만 통계적 유의차를 나타내었다. 또 다른 노화관련 호르몬인 DHEA-S의 변화에서는 탄성저항운동과 단백질 섭취군과 탄성저항운동군에서 12주간의 운동 후 통계적으로 증가하였다. 하지만 대조군에서는 감소한 것으로 나타났다. 이러한 결과를 바탕으로 다음과 같은 결론을 도출할 수 있었다. 고령여성들에게 규칙적인 근력운동과 단백질섭취는 노인여성의 기능적 체력 개선과 노화관련 호르몬기능에 긍정적인 영향을 줄 수 있을 것으로 사료된다. 하지만 노인을 위한 맞춤형 근력운동이 반드시 적용되어져야 할 것이다. Purpose: The purpose of this study was to examine the effect of elastic resistance exercise and protein intake on functional fitness and aging hormones in elderly women. Methods: This study was objected to elder women who are in between 65 to 74 years old. We splitted twenty three participants into three different groups; RIP Training Protein intake group(RTP), RIP Training group(RT), and Control group(CG). And then measured their functional fitness and aging hormones first hand for latter comparison. Exercise program was for 12 weeks, three times a week and 60minutes of exercise each. Protein intake happened right after the exercise. Results and Conclusion: The results follow. Skeletal muscle mass increase significantly in RTP group. Other groups, however, did not show much significant different. While all of the groups shows increment of weight, only RT group shows loss of body fat. In fact, body weight in the RT group increased caused by increment of skeletal muscle mass increase. To find the functional fitness, we tested lower body strength, upper body flexibility, agility, and dynamic balance. As results, RTP and RT showed improvement. Among the improvement, RTP"s lower body flexibility improved significantly. Significant increase of estrogen, growth hormones, and DHEA-S, which are aging hormones, was shown in RTP and RT. CG"s aging hormones, however, decreased. DHEA-S rate showed significant difference between RTP and RT, and CG. As a result, 12 weeks of exercise and protein intake not only improve muscle strength, endurance, flexibility, agility and dynamic balance, but also decrease body fat. Moreover, it arouse secretion of aging hormone. Thus, this study can conclude that exercise and protein intake is helpful to improve elder women"s functional strength.

The purpose of this study was to investigate the changes of melatonin, dehydroepiandrosterone sulphate(DHEA-S) and growth hormone(GH) associated with aging and stress hormone and body composition by 12weeks exercise in middle age female with overweight. Participants were 27 who were circuit exercise(n=9), aquarobics exercise(n=9), and control group(n=9). Blood samples were collected prior to exercise treatment and 12weeks post-exercise. melatonin levels significantly increased postexercise in circuit exercise; DHEA-S and GH levels significantly increased post-exercise in circuit exercise and aquarobics exercise. There were no significant differences of cortisol levels in all groups. Epinephrine and norepinephrine levels significantly decreased post-exercise in aquarobics exercise. But there were no significant differences in circuit exercise. The findings suggest that circuit exercise and aquarobics exercise can stimulate DHEA-S and GH production in middle age female with overweight and that stress hormonal responses to exercise type differ between circuit exercise and aquarobics exercise.
