Abstract

The purpose of this study was to investigate the relationship between teaching experience, regular exercise habit, health related fitness, bone density and arterial stiffness (PWV) by teaching experience of Korean female teachers. The subjects are 390 (age of 46.48±7.2) female teachers participating in teacher training programs. Teaching experience was divided into five categories (less than 10 years, less than 15 years, less than 25 years, over 25 years). Regular exercise habits were determined by how often they exercise regularly per week. Also, health related fitness (% fat, active physical fitness), arterial stiffness (PWV) and bone density (T-Score) were evaluated. Exercise habit, physical fitness awareness and health awareness were significantly higher in over 20 years compared to less than 10 years. Also, bone density was significantly higher in less than 10 years compared to over 20 years, whereas PWV was not different significantly in teaching experience. There were significant correlation between exercise habit and health related fitness as well as between exercise habit and bone density. Also, there were significant inverse correlation between exercise habit and arterial stiffness as between bone density and arterial stiffness. Therefore, it is necessary for teachers to take part in various health training courses or programs regularly for their health.

Abstract

Background/Objectives: Backward walking can be used as an exercise therapy program for prevention of low back pain. Accordingly, the purpose of this study was to investigate the effect of backward walking on isokinetic muscular function, low back pain index and lumbosacral angle in unilateral exercise athletes. Methods/Statistical Analysis: The subjects are 25 (age 21.37 ± 2.06 years, height 171.85 ± 4.12 cm, weight 71.97 ± 5.74 kg, exercise career 7.03 ± 1.95 years, pain duration was 6.05 ± 0.75 months) unilateral exercise athletes (golf, bowling and shooting player). Backward walking was performed with a frequency of three times a week (Tuesday, Thursday, Saturday), by 60 minutes at a time for 10 weeks. Comparison of related variables before and after backward walking was verified by paired t-test. Findings: The present study shows that extensor and flexor of lumbar were significantly increased after backward walking. Lumbosacral angle was significantly decreased after walking back. In addition, low back pain index such as VAS and VRS were each showed a significant decrease. Application/Improvements: In conclusion, backward walking represents that it improves muscle strength of the lumbar vertebra and reduces the lumbosacral angle and appeared to reduce the pain of the lumbar vertebra showing that the exercise program can be used in the prevention of low back pain.

Abstract

Objectives: This report has purpose of learning how the tendency of achievement goal affects self-regulated learning and physical self-efficacy for middle school students who participate in school sports club activities. Methods/Statistical Analysis: Among the students who participate in middle school sports club, total of 674 students composed of 426 male students and 248 female students were selected as target. The measurement of variables was performed using a questionnaire, comparison of related variables (gender, proficiency evasion, proficiency access, execute access, execute evasion, physical ability, self expression) were verified by unpaired t-test and multiple regression analysis. Findings: Among the factors of achievement goal according to gender, the proficiency access goal was significantly higher in male students, and the proficiency evasion goal was particularly high for female students. Also, as the factor of achievement goal that influence the inner control of self-regulated learning, it was found that the proficiency access goal significantly affect both male students. The factor of achievement goal that affect the recognized physical ability of physical self-efficacy was found to be the proficiency access goal that positively affect both male and female students. Also, the factor of achievement goal that affect the physical confidence of self-expression was found to be the proficiency access goal that positively affect the male students. Improvements/Applications: This research was limited to middle school students and the research method was limited to surveys, which are cross-sectional studies. Therefore, there is a limitation of interpreting the research result as the characteristic of all students.
