PURPOSE: The aim of this research was to examine the effects of short-term weight loss on stress hormone and EEG in weight athletes. METHODS: Subjects were divided into 3 groups: CON (n=7, control), LWL (n=7, low weight loss), and HWL (n=7, high weight loss). RESULTS: The results were as follows: 1) There were significantly decreased on body fat and WHR in HWL group (p<.001). However, body mass was significantly increased in HWL group (p<.01). 2) There were no significant group by time interactions for stress hormones on all items. Epinephrine was significantly decreased after weight loss in HWL group (p<.05). While, norepinephrine (p<.05) and cortisol (p<.001) was significantly increased after weight loss in HWL group. 3) There were no significant group by time interactions for theta and SMR waves of EEG. However, alpha, mid-beta, high-beta and gamma waves showed significant difference group by time interactions (p<.001). CONCLUSIONS: It is recommended that you lose no more than 5% of your weight for stress hormones to stay in the best condition before the match. However, it is recommended that you keep your normal weight at the weight of the match to participate in the competition to maintain your best condition in the brain wave shift.

The purpose of this study was to explore the formation and development process of Korean women's ice hockey team and the reality of winter sports inherited from the film ‘Take Off 2’. For this purpose, text selection, data collection and textual analysis were performed. The results were as follows. First, the development process of the Korean female ice hockey team, which is reproduced in the movie ‘Take Off 2’, is as follows. The first stage was not a purpose but a team of means: a screen of the Olympic Winter Games. Step 2 is revealed as a member of low awareness: the stranger of the world ice hockey, the third stage is a difficulty of forming a leader and player: variety of team members. In the fourth stage, the time of the turbulence: the conflict between the members and the lack of training support, and the result of fifth stage was the outcome of combative spirit: the depressed reality of the national representative was derived. Second, the reenactments of the reality of Korean winter sports in the film ‘Take-Off 2’ were due to the two-sides of sports powers: the intensification of specific sports, the lack of athletes infrastructure: the presence of strict elite athletes, a world that only remembers gold medals, losing its own certificates :

In this study, the effects of 12-week endurance exercise and D-ribose-intake on male college students’ blood fatigue substance amount, VO₂max and cortisol level were analyzed to investigate the feasibility of D-ribose as an ergogenic aid. A total of 14 male college students were assigned to either the D-ribose-intake plus endurance exercise group (n=7), or to the endurance exercise group (n=7). D-ribose was administered three times a day for 12 weeks, Endurance exercise was conducted using a bicycle ergometer with a training strength of 70% VO₂max for 60 minutes each time five days a week for 12 weeks, Using two-way repeated measures (ANOVA), correlation effects were tested, conclusion followed. First, no correlation effects were observed in all the body composition, but body weight increased significantly in the exercise+ribose-intake group. Second, in terms of the change in fatigue substances, LDH and IP showed correlation effects, and those levels in the exercise+ribose-intake group significantly decreased. Third, the change in the VO₂max showed correlation effects, and VO₂max of the exercise+ribose-intake group significantly increased. Fourth, No main and correlation effects were observed in the change in the cortisol level.

허유섭(Huh, Yu-Sub),김귀백(Kim, Kwi-Baek),조영민(Jo, Young-Min),신재숙(Shin, Jae-Suk) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.1

The purpose of this study is to understand if ATP supply promotion, which is induced by D-ribose taken during high intensity anaerobic exercise, is effective in showing explosive and strong power and what kind of things it influences on stress hormone after taking D-ribose and practicing resistance exercises for 12 weeks. Thus, it examined male university students in their 20s who have no regular exercising experience by dividing them into RRT(ribose+resistance training group) 7 members and PRT(resistance training group) 7 members, and then they took 40 ㎎ D-ribose/weight dissolved in 200 ml drinking water for 12 weeks. PRT group took placebo(refined sugar, 2g) dissolved in 200 ml drinking water in the same way. The exercise program was the weight training; during 1st-6th weeks 2 sets of 15 repetition at 60% of 1-RM, and during 7th-12th weeks 3 sets of 15 repetition at 70% of 1-RM. The statistical technique used was two-way ANOVA and paired t-test as post-hoc analysis. Experiment result is as followings: 1. In body composition change there was no interaction between body fat percentage and lean body percentage, but the body fat percentage was decreased and lean body percentage was increased in 12th week compared with prior ones in both RRT and PRT. 2. In anaerobic exercise capability there was no interaction in all items, and PP, AP and MP were increased in 12th week in both RRT and PRT compared with prior ones, and PD was decreased in 6th and 12th weeks in both of RRT and PRT. 3. In stress hormone change testosterone showed no interaction and no main effect. Cortisol was increased in 6th week in both of RRT and PRT compared with prior one. Reviewing the results, both of D-ribose taking+resistance exercise group and resistance group showed positive changes in body composition, anaerobic exercise capability and stress hormone, however there was no difference between the groups. Hence, there was no synergy effect from D-ribose taken.

The aim of this research was to examine the correlation between body composition(weight, lean body mass, skeletal muscle mass, fat mass, BMI, %fat, WHR) and bone mineral density of combat sports athletes. Subject groups were divided into ssireum(n=10), wrestling(n=10), boxing(n=10) and taekwondo(n=10). For date analysis one-way ANOVA(LSD) and Pearson"s correlation coefficient were used. There were statistically significant differences on all variables of body composition. Weight, fat mass and %fat of ssireum group were higher than those of boxing and taekwondo groups. Lean body mass and skeletal muscle mass of ssireum were higher than those of wrestling, boxing and teakwondo groups. BMI of ssireum was higher than that of wrestling, boxing and teakwondo groups, and BMI of wrestling group was higher than boxing group. WHR of ssireum and wrestling groups were higher than that of boxing and taekwondo groups. However, T-score showed statistically no significant difference among four groups. All items of body composition were expected to significantly correlate with bone mineral density, but they showed no significant correlation in four groups. Bone mineral density of combat sports athletes were considered to be relevant to the exercise form and density, volume of exercise rather than body composition. Further studies on relation between bone mineral density and physical fitness, exercise program should be performed on various ages and lots of combat sports athletes.
