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.

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 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.

This study aimed to determine the effects of mat Pilates on isokinetic muscular strength of knee, proprioception, and static balance in older women. Forty one sedentary, apparently healthy females aged 63-68 and older were randomly assigned into a control(CG, n = 22) or an Pilates exercise(PEG, n = 19) group. A pilates exercise program was applied to the subjects one hour per day four days per week during twelve weeks. All subjects underwent preand post-tests in which isokinetic muscular strength of knee, proprioception, and dynamic balance were assessed. Improvements were observed in balance, mobility, and upper and lower extremity muscle strength in the Pilates exercise group(p<0.05). No significant differences in any outcome measures were observed in the control group(p<0.05). In conclusion, Pilates exercises is effective in improving static balance, flexibility, reaction time, and muscle strength as well as decreasing the propensity to fall in older women.

강형숙(Kang Hyeong Sug) 한국사회체육학회 2003 한국사회체육학회지 Vol.19 No.2

This study was designed to examine the effect of resistance training program to on the serum lipid, immunity and blood parameters in middle-aged women who had been engaged in continuous aerobic exercise(n=11, age=49.5). The resistance training program during 12 weeks were composed of sandbag, dumbbells and band were enforced three times per week. In serum lipid, total cholesterol and low-density lipoprotein significantly decreased(p<.05), and high-density lipoprotein cholesterol showed noticeable increase (p<0.001). In blood iron-content level, total iron binding capacity showed statistically noticeable increase (p<0.001), and ferritin were decreased but with no statistical signification. The immunoglobulin levels were not significantly different. Consequently, 12 weeks resistance training program was turned out to cause positive change in serum iron and lipid of middle-aged woman who performs aerobic exercise regularly. This result can be used as a basic data of various studies on the change of body following the exercise pattern for the middle-aged who perform exercise.

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.

강형숙(Hyung-Sook Kang),오봉석(Bong-Seok Oh),지용석(Yong-Seok Jee),조기찬(Ki-Chan Cho),윤진환(Jin-Hwan Yoon) 한국생활환경학회 2010 한국생활환경학회지 Vol.17 No.5

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 examine the changes of body composition, hematological anemia parameters, erythrocyte morphological and inflammation protein, blood component after 7 days RWL(rapid weight loss, 6.24% of total body weight) through combined method with total food restriction, exercise and dehydration. Blood samples were taken the day before the maximal exercise test, within 1min after the maximal exercise test and 30min after maximal exercise test both before and after short-term weight loss. The result were as follows: The average weight showed a significant difference between before and after rapid weight loss(p<.05). VO2max showed a significant decrease after rapid weight loss. ESR(Erythrocyte sedimentation rate), CRP(C-reactive protein) and Heinz body formation showed a significant increase after rapid weight loss. Exercise-induced ESR, CRP and Heinz body formation showed similar responses in both before and after, but occurred at higher levels in after RWL. It was concluded that rapid weight loss techniques result in deleterious effects on Hematological Anemia Parameters & Erythrocyte Morphological in taekwondo players.
