PURPOSE This study analyzed the effect of dynamic lumbar kyphosis on the biomechnical factors affecting the lumbar joints during deep squats. METHODS Thirty adults in their 20s who had experienced weight training for more than one year participated in this study (age: 23.4±3.5years old, height: 175.3±4.3cm, weight: 75.8±6.5kg, squat single repetition maximum (1RM) weight: 115.3±19.5kg). Under both restricted dynamic lumbar kyphosis (RDLK) and dynamic lumbar kyphosis (DLK), subjects completed one repetition of deep squats at a load of 70% of their 1-RM weight. To verify the consistency of deep squat movements performed under DLK and RDLK conditions, intra-rater reliability was analyzed using intra-class correlation . The biomechnical variables of the lumbar joint were calculated during DLK and RDLK deep squats. Paired sample t-tests (IBM SPSS 27.0, Armonk, New York, USA) were used for statistical verification. RESULTS During the deep squat movement performed in DLK and RDLK conditions, the peak angles of the ankle, knee, and hip joints, the minimum height of the pelvis, and the time and tempo showed statistically high reliability, confirming the accuracy of the movement. The peak flexion angle and moment, left flexion moment, left rotation moment, and compression force factors of the lumbar joint during deep squat were significantly lower in RDLK than in DLK. CONCLUSIONS Restricting lumbar dynamic kyphosis during deep squats is essential for decreasing the risk of lumbar joint injury.
Purpose The purpose of this study was to investigate differences among perfectionism, anxiety, and aggression in contact and non-contact sports and verify the structural relationship model of perfectionism, anxiety, and aggression in the field of sports. Methods Male college athletes (N=299) participated in the study and perfectionism, anxiety, and aggression questionnaires were utilized after their verification of validity and reliability were conducted. The descriptive statistical analysis, the multivariate analysis, the correlation analysis, the structural equation analysis, and the multi-group analysis were conducted. Results The results are as follows: First, the level of perfectionism, anxiety, and aggression were significantly different between contact and non-contact sports (F=4.316, p<.001). Additionally, subfactors of aggression such as hostility, physical aggression, and verbal aggression factors in contact sports showed a higher average than non-contact sports. Second, perfectionism positively affected anxiety (t=6.936, p<.001) and anxiety positively affected aggression (t=3.380, p<.001). Moreover, the complete mediation effect of anxiety was found in the path from perfectionism to aggression (β=.152, p<.01). Finally, we compared path coefficients between contact and non-contact sports. As a result, positive causal relationships was indicated in the path from anxiety to aggression (β=.511, p<.001) in contact sports. However, it was not discovered in non-contact sports (β=.149, p>.05). Conclusions In conclusion, perfectionism causes anxiety and anxiety is a mediator leading to aggression in sports. Such effect is more predictable and observable in contact sports in which aggression is more favorable and encouraged. Implications and suggestions for future research are discussed.
Based on public sports facilities’ census data, this study attempts to empirically analyze to the factors affecting the operating balance and use of public sports facilities(PSF). Analysis was carried out through multiple regression analysis using SPSS and location characteristics analysis using GIS. The total floor area and population was confirmed to influence operating balance and use(DV). Management body influence differed for DV (use and operating balance of PSF) by type of PSF. Consequently, this requires diversification of the management body. The size of facilities and location characteristics(population and zoning) are positive effect on the operating balance and Use of PSF. In order to solve the problem of location restriction and security of marketability, it is possible to take into account the integrated management and sports club’s use of large-scale sports facilities.
