Purpose The purpose of this study is to analyze the performance contents of men's floor exercise and to provide basic materials for achieving excellent results at world competitions. Methods Teams ranked 1 - 12 who participated in the World Championships' floor movement group competition selected a total of 59 players by the convenience sampling method and carried out technical statistics, frequency analysis, member variable variance analysis, and post hoc analysis. Results First, as a result of frequency analysis of the difficulty of each group, all the teams ranked 1 to 12 liked the most difficulty of C and found that they do not like the F difficulty the most. Secondly, there was a difference in average for each group's start score, ranking 1st to 4th> 5th to 8th> 9th to 12th place. Thirdly, there was a difference in average of difficulty levels for each group B, C, E, and it became very significant with E difficulty.Results of post hoc analysis B difficulty (9th to 12th> 1st to 4th, 5th to 8th), C difficulty (9th to 12th> 1st to 4th), E difficulty (1st to 4th> 5th to 8th ·9th to 12th). Conclusion These results show that in floor exercise, the art of more than C difficulty and the connection technology of A, B, C, difficulty, E and F, difficult difficulty such as difficulty, creative and dynamic performance composition is excellent It clearly states that it is a condition for getting results.
The purpose of this study was to verify the effect on elementary school students in the exercise start stage by performing a sport psychological skill training to improvement of psychological skill and life skill. Participants were eight elementary school boys volleyball player. The program consisted of psychological skills and life skills in educational counseling model of Visek et al(2009). It was conducted 40-50 minutes a session in total for 22 sessions. Data was collected through a psychological test, worksheet and participant observation, in-depth interviews. The collected data was analyzed to verify difference by paird t-test after pre-middle-post test and to extract meaningful data category. Quantity analysis showed that a result of sport psychological skill test proved a significant difference in willingness to overcome, confidence, concentration, anxiety regulation. Life skill test were no significant differences in all factors. However, the rise of scores was observed on result of the pre-middle paired t-test of life skill during season. Quality analysis showed possibility of goal setting, concentration on the routine, decrease of competitive anxiety, increase of positive thinking, self-understanding and understanding of others, promotion of communication among team members.

The aim of the study was to examine the tracking of body composition and physical fitness in boys and girls for 6 years. Thirty-seven boys and girls participated throughout the study. All measurements were performed annually. Body height, body weight, circumferences and skinfold thicknesses were measured and skeletal maturity was assessed. Body composition and bone mineral density were measured by DXA. Nine physical fitness tests were administered. Results of the study showed that there are significant interaction effects of time and group for body height(p<.01), waist circumference(p<.001), and skinfolds at triceps(p<.01), suprailiac(p<.01), thigh(p<.001) and medial calf(p<.01). All anthorpometric variables except skinfold thickness increased during the study period. Significant interaction effects of time and group were found for percent body fat(p<.05) and bone mineral density(p<.01). Percent body fat and fat tissue increased in boys from 7 to 11 years, then decreased in 12 years. Lean tissue(p<.001), bone mineral content(p<.001) and bone mineral density(p<.001) increased both in boys and girls throughout the study. There were significant interaction effect of time and group on sit and reach, standing long jump and sit-ups. In conclusion, percent body fat and fat tissue increased until 11 years, lean tissue and bone mineral density increased throughout the study both in boys and girls.
