Purpose This study examines the regional differences in fall-related physical fitness and fall experience characteristics between Korean and Japanese elderly people. Methods The study includes 176 elderly residents of Gifu(35 male, 73.5yrs; 141 female, 72.4yrs) and 147 residents of Ulsan(46 male, 75.6yrs; 101 female, 75.6yrs). One-legged stance, hand grip strength, knee extension strength, 10 m gait, timed up and go test, 30-s chair stand, sit and reach, and reaction time were measured to examine the fall-related physical fitness. A questionnaire survey was also conducted to investigate the characteristics of the fall experiences. Results The elderly in Ulsan experienced a lot of falls compared to those in Gifu. Many of the fallers in Ulsan have fallen forward due to tripping, and they have often fallen backwards by losing balance. In addition, 14% of them suffered a bone fractured. The one-legged stance, hand grip strength, 10m gait, timed up and go, 30-s chair stand, and reaction time of the elderly in Gifu were superior to those in Ulsan. Conclusion In order to reduce the fall rate through improvements to fall related physical fitness and the awareness of fall prevention, various professional fall prevention programs and policies should be proposed, and they should be implemented systematically for community living elderly people.
Active participation in Moderate to Vigorous Physical Activity(MVPA) is the indicator of healthy development for adolescents. However, Korean adolescents’ MVPA have continuously declined, and Korean adolescents have lower levels of MVPA compared to adolescents in other countries. Considering this issue, the purpose of this study is to examine the effectiveness of SPARK M-SPAN program to promote adolescents’ MVPA in P.E. classes and to understand how the promotion of adolescents’ MVPA occurs. To collect data, this study used Sequential Mixed Method and GT3X accelerometers. A total of 168 adolescents (84 in an experimental group and 84 in a control group) participated in this study for the quantitative data analysis, and six students and a teacher were interviewed for the qualitative data analysis. Paired t-test showed that students in SPARK P.E. classes experienced the significant decreases of sedentary behaviors(-339.6 sec) and low intensity P.A.(-96.9 sec) at p<.05 and the significant increases of moderate(+99.3 sec), vigorous(+252.4 sec), and very vigorous intensity P.A.(+84.7 sec) regardless of gender difference at p<.05 except for female students’ moderate intensity P.A.. The qualitative data analysis showed that SPARK classes gave students positive learning environments and led them to experience enjoyment and achievement-orientated learning Key teaching strategies of SPARK program and future research suggestions were provided in the discussion section.
The purpose of this study was to examine the relationship of obesity index, fitness and cardiovascular risk index in middle and high school students. Obesity index, fitness score and cardiovascular risk index were measured from 1,044 middle and high school students. The results of relation between obesity index and fitness showed that the higher obesity index had significantly lower fitness score for both boys and girls (boys: p<0.001, girl: p<0.05) The results of relation between obesity index and cardiovascular risk index indicated that the higher obesity index had significantly higher cardiovascular risk index for both boys and girls (boys: p<0.001, girl: p<0.001). Moreover, The lower fitness index showed significantly higher cardiovascular risk index regardless of gender in middle school students (boys: p<0.001, girl: p<0.01). Therefore, the results of this study indicated that obese adolescents had the lower fitness level and high possibility of cardiovascular risk.
It has been known that β-alanine supplementation induce the increment of carnosine in vivo and was effective in delaying fatigue by buffering the hydrogen which was formed during exercise. This study was designed to investigate the effects of 4 weeks of β-alanine supplementation on physical fitness and blood lactate concentration in middle school soccer players. Nineteen middle school soccer players were randomly assigned to either one of two groups, i.e., β-alanine group (n=10) and placebo group (n=9). Subjects in β-alanine group consumed β-alanine 2 g/day during 1st and 2nd week, as well as 3 g/day during 3rd and 4th week, whereas subjects in placebo group consumed maltodextrin in the same manner. All subjects ate same menu and trained same amount at the same training camp during the intervention period. Body composition, aerobic capacity, anaerobic capacity, isokinetic function, and blood lactate concentration during maximal GXT were measured at pre- and post-test. Main results of the present test were as follows: 1) Fat mass and percent body fat decreased significantly in β-alanine group. 2) No significant changes were found in variables related to aerobic capacity in both groups. 3) Average power increased significantly in β-alanine group. 4) Isokinetic muscular endurance increased significantly in β-alanine group. 5) Blood lactate concentration did not change in eithet group; however, blood lactate concentration immediately after maximal GXT in β-alanine group tended to be increased more than placebo group. It was concluded that β-alanine supplementation would have positive effects for improvement of body composition, anaerobic capacity, and muscular endurance in middle school soccer players.
The purpose of this study was to investigate basal physical fitness and smash speed of elite national badminton players. To perform this study, total forty six korea national badminton player were participated : twenty two male players(age : 20.90±2.24years, height : 179.30±5.40cm, weight : 73.80±7.12kg, career : 11.27±1.88years) and twenty four female players(age : 19.45±1.95years, height : 167.83±4.36cm, weight : 61.39±3.60kg, career : 9.50±2.47years). Each subjects performed the 6 basal physical fitness trials : agility, muscular endurance, muscular strength, flexibility, balance and cardiorespiratory endurance. And the speed of badminton smash were analysis by using radar gun when players were standing smash success. To determine the difference between two groups, independent samples test was used. As a result, we found that there was a large difference male players and female players in basal physical fitness and smash speed. First, male players were significantly strong in agility(side step 10%), muscular endurance(repetitional jump 12%), muscular strength(left grasping power 3%, right grasping power 31%) and cardiorespiratory endurance(20m suttle run 31%). On the other hand, female players were relatively strong in flexibility(sit and reach 27%) and balance(standing on one leg with eyes closed 51%). Second, maximum smash speed show that male players were about 57km/h(24%) faster than female players(male : 247.72km/h, female : 190.37km/h). Based on the findings, we shall be applicable training program to improve flexibility, balance of male athletes and agility, muscular endurance, muscular strength, and cardiorespiratory endurance of female athletes. our results will be appliable to improve the athletic performances of national badminton players by the coaches in the future.
Although mega sporting events are becoming an effective means of brand communication, there has not been systematic research on involvement development and perceived fit enhancement through the sporting events. This study developed and tested a conceptual model delineating the impact of consumer involvement on perceive fit, and brand equity in mega sporting event context. Using quota sampling method, 1,847 participants (916 from IAAF; 931 from the F1) were recruited from several different cities in Korea during the mega-sporting events. Structural equation modeling were employed to examine the relationship between research constructs and test the model respectively. The study found that mega event involvement has a positive effect on perceived fit; and perceived fit influences brand equity(brand awareness, perceived quality and loyalty) toward event sponsor brands. The direct effects of involvement on sponsorship effectiveness (brand awareness, perceived quality and loyalty) did not have a significant effect on brand equity. The findings also reveal the mediating effect of perceived fit on brand equity.
PURPOSE This study examines how fitness centers’ care services affect the MZ generation’s perceived value, exercise attitude, and exercise commitment and how perceived value mediates this impact. METHODS Patrons aged 20–30 who used fitness centers in the Seoul and Gyeonggi regions participated in a questionnaire survey from January to February 2024, providing a total of 233 responses. Using SPSS 21.0 and AMOS 21.0, the data underwent frequency analysis, reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling. RESULTS First, perceived caring services had a significant effect on perceived value. Second, perceived value had a substantial influence on exercise attitude. Third, perceived value had no significant effect on exercise commitment. Fourth, exercise attitude significantly drives exercise commitment. Fifth, perceived caring services did not significantly affect exercise attitude or commitment. Sixth, perceived value fully mediates the relation between perceived caring services and exercise attitude. Seventh, perceived value had a full mediating effect on the association between perceived caring services and exercise commitment. Finally, tailored services and emotional support were identified as key factors in fostering MZ individuals’ positive exercise experiences and commitment. CONCLUSIONS Fitness centers should develop strategic services reflecting their customers’ goals and values to enhance their exercise attitudes and commitment and ultimately secure long-term customer loyalty.
PURPOSE This study assessed Taekwondo’s impact on functional fitness and health-related quality of life (HRQoL) in older women from South Korean multicultural families. METHODS Through purposive sampling, 16 participants were divided into an experimental group that underwent a 12-week Taekwondo training program and a control group without this intervention. RESULTS Pre- and post-intervention assessments showed that the Taekwondo group experienced significant improvements in both functional fitness and HRQoL. These findings suggest that Taekwondo could be an effective physical activity for enhancing the well-being of older women in multicultural families, advocating for inclusion of culturally sensitive physical activities in health promotion programs targeting this demographic. CONCLUSIONS This study contributes to the growing body of evidence supporting physical activity’s benefits for elderly populations, particularly in multicultural family dynamics.
PURPOSE This study investigated the effects of 12 weeks of clubbell and stepbox training on physical fitness, badminton skills, and fatigue in male badminton, grade A (top grade) club members aged 20–30s, with over 5 years’ experience. METHODS Participants in a training group (TR: n=15) engaged in 12 weeks of clubbell and stepbox circuit training involving maximum 8–12 reps of clubbell exercises and stepbox exercises at over 77% of HRmax for 50–55 min/sessions three times a week. Participants in a control group (CON: n=15) maintained their normal lifestyle pattern during the same intervention period. Dependent variables were measured and compared using repeated measures two-way ANOVA. RESULTS The main results were as follows: 1) The groups showed no significant differences in body composition. 2) Regarding physical fitness, VO2max, relative peak power, relative average power, grip strength, push ups, repeated jump squats, SSPT (seated single-arm shot-put test), 10 m sprint, and hexagon agility increased significantly in the TR, while push ups decreased significantly in the CON. 3) As for badminton skills, forehand clear accuracy, badminton agility, badminton endurance, and smash speed increased significantly in the TR. Forehand clear accuracy decreased significantly in the CON, but badminton agility and smash speed increased significantly. 4) The groups showed no significant differences in fatigue. CONCLUSIONS In male badminton club members aged 20–30s, 12 weeks of clubbell and stepbox circuit training effectively improved physical fitness and badminton skills. However, lack of any improvement in body composition and fatigue warranted further research in these areas.
