This study through the notion of conventional thinking, seeks to understand and resolve the problem of fixed reproduction in the violence culture that is accepted in the name of voluntary compliance among college athletic departments. Violence in college athletic departments indicates that it acts as a mechanism for maintaining the pertinent group between a‘vertical relationship’ (i.e., leaders and athletes) and a‘horizontal relationship’(e.g., solidarity). The social actors performing the violence are reproduced through habitus embodied by the social condition and the environment according to their hierarchy. In other words, there exit a vertical and horizontal relationships among the college athletic departments from which athletes acquire the violence culture and change themselves as forwarders from beneficiaries. As a result, such a violence culture is inherited and simultaneously reproduced in the name of tradition. Therefore, paradigm shift should be made from the authoritarian vertical relationship to the universal relationship that values the respect for human ‘diversity’in order that the violence culture can be abolished. All human relationships in a democratic society must be guaranteed to have interchangeable and interdependable horizontal communication between the social members.

Vertical studies about changes of old people`s physical fitness of daily living are restrictive. So in this study, as we compared residents` physical fitness of daily living by ages, we intended to offer basic data for healthy old age, improving quality of life. The number of persons by ages is 182 in teens, 125 in twenties, 123 in thirties, 154 in forties, 169 in fifties, 318 in sixties, 298 in seventies, total 613 males and 756 females of 1369 are tested by muscular strength, muscular endurance, flexibility, balance, agility, power, and cardiorespiratory endurance. In the result of male, the balance falls under 50% of highest point in forties, the flexibility and muscular endurance fall in fifties, the muscular strength and power and agility fall in sixties. In the result of female, the balance and muscular endurance fall under 50% of highest point in forties, the agility and power fall in sixties, the flexibility and muscular strength fall in seventies. Like this, dropped physical fitness raises the ratio of disease relaxant and affects the healthy quality of life. So at least, to secure the physical fitness of daily living, we think the foundation of continuously participating in exercises from forties should be built.

The purpose of this study was to establish the optimun %heart rate reserve(HRR) by bench step heights and predict relationship of %HRR of bench step heights for developing cardiorespiratory endurance in obese and normal male high school students. Eighteen obese & twenty-one normal male students in high school students participated in the bench stepping exercise for 20 minutes(125bpm, "up-up" "down-down") at each bench step height(5cm, 10cm, 15cm, 20cm, 25cm, 30cm, or 40cm), and the exercise in bench step heights was randomized using a balanced Latin Square. To find out the most appropriate aerobic threshold of each bench step heights, the % HRR by bench step heights was established and predicted on Karvonen`s formula. Statistical analysis was made repeated two-way ANOVA and Student`s Newman Keul test, and regression analysis was predicted of each bench step height and %HRR. The results are as follows: 1. The exercise intensity in directly measured %HRR The obese group was established as 33.39% at 5cm bench step height, 39.30% at 10cm, 54.12% at 15cm, 70.22% at 20cm, 76.69% at 25cm, 82.78% at 30cm, 88.98% at 35cm, and 89.79% at 40cm in actual %HRR; the normal group was established as 26.34% at 5cm bench step height, 29.11% at 10cm, 38.83% at 15cm, 44.20% at 20cm, 54.07% at 25cm, 59.98% at 30cm, 70.46% at 35cm, and 75.09% at 40cm in actual %HRR, These results of two-way ANOVA according to %HRR among each bench step height and group showed significant difference in groups(F=268.32, p<0.001) and bench heights(F=12.24, p<0.001), but interactions was not significantly different(F=0.40, p>0.05). 2. The exercise intensity in indirectly measured %HRR The obese group was established as 37.47% at 5cm bench step height, 46.17% at 10cm, 54.87% at 15cm, 63.57% at 20cm, 72.27% at 25cm, 80.97% at 30cm, 89.97% at 35cm, and 98.37% at 40cm in pre-estimated %HRR(%HRR equation=28.77+1.74·Heights: t=4.84, p<0.001, R2=0.90, SEE=7.63), and the normal group was established as 23.87% at 5cm, 31.27% at 10cm, 38.66% at 15cm, 46.06% at 20cm, 53.45% at 25cm, 60.8 5% at 30cm, 68.24% at 35cm, and 75.64% at 40cm t(%HRR equation=16.48+1.48·Heights: t=48.61, p<0.001, R2=0.84, SEE=7.28). Thus, directly measured %HRR to improve cardiorespiratory endurance was established as 10cm, 15cm, 20cm, 25cm, and 30cm bench step heights in obese group, and indirectly measured %HRR was established as 15cm, 20cm, 25cm, and 30cm. Also, directly & indirectly measured %HRR was established as 20cm, 25cm, and 30cm, 35cm, and 40cm bench step heights in normal group is above the minimum guideline for improving aerobic capacity recommended by the ACSM. It seems that directly & indirectly measured %HRR in these bench stepg heights may indeed offer an adequate aerobic training stimulus for obese & normal high school students.

The purpose of this study was to establish the optimal target heart rate and %maximal heart rate reserve (%HRR) by submaximal bench stepping exercise according to bench step heights in normal male high school students. Twenty-eight normal male high school students participated in bench stepping exercise for 20 minutes at each bench step heights (5cm, 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 40cm), and the exercise in bench step heights was randomized using a balanced Latin Square. To find out the most appropriate training stimulus, exercise intensity by each bench step heights was established by the % HRR of Karvonen`s formula. Statistical techniques for data analysis were repeated measure two-way ANOVA to determine the difference between each bench step heights and % HRR in the bench step heights, and post-hoc test was utilized Student`s Newman Keuls (SNK). The results are as follows: the level of % heart rate reserve in each bench step heights was established 24%-28% at 5cm, 27%-31% at 10cm, 36%-41% at 15cm, 41%-46% at 20cm, 47%-56% at 25cm, 49%-62% at 30cm, 56%-75% at 35cm, and 56%-85% at 40cm. These results of repeated measure two-way ANOVA according to % exercise intensity among each bench step heights and exercise durations showed significant different in % exercise intensity (F=2105.913, p<.001), exercise durations (F=12.987, p<.001), and interaction (F=1.776, p<.001). Therefore, the SNK test of % exercise intensity in higher bench step heights and exercise durations showed significant increase in higher exercise intensity increased by bench step heights and exercise than that of lower bench step heights and duration. Thus, actual exercise intensity over 41% HRR was established as 15cm, 20cm, 25cm, 30cm, 35cm, 40cm, and the values of %HRR were greater than those used by the American College of Sports Medicine. In conclusion, it seems that bench step heights for 20 minutes may indeed offer and adequate aerobic training stimulus in normal male high school students.

The purpose of this study was to evaluate an influence of plasma oxidant and anti-oxidant enzyme activity, and changes of percent body fat following Eriobotrya japonica extract supplementation during acute exercise performance in elite trained athletes. Total 12 subjects were participated in this study and divided into 2 groups (control group(CTG); n=6, loquat supplement group(LSG); n=6). All subjects had no history of injuries for last 6 months. LSG took Eriobotrya japonica extract supplementation for 4 weeks. All data of this research was analyzed by SPSS/PC 18.0 and signficant level was p<.05. The results of this study were as follow; In dialdehyde(MDA) concentration, there was a significant difference between rest and recovery -30 min of pre-(p<.01) and post(after 4 weeks)(p<.05) tests in CTG. In LSG, there was a significant difference between in rest and recovery -30 min of pre test(p<.05). In superoxide dismutase(SOD), there was a significant difference between in rest and immediately after exercise and recovery -30 min of post test in LSG(p<.01). In catalase(CAT), there was a significant difference between in rest and recovery -30 min of post test in CTG(p<.01). In LSG, there was a significant difference between in rest and immediately after exercise and recovery -30 min of post test(p<.05). As results above, It was suggested that long-term Eriobotrya japonica extract supplementation in athletes limited plasma MDA product during acute exercise, and positive effect on the improvement of anti-oxidant enzyme activity.
