The challenges female athletes face, particularly the Female Athlete Triad, persist.However, effective weight management methods in this context remain unclear. This study aims to clarify the weight management strategies used by female collegiate athletes in aesthetic sports, explore their perceptions of weight management, AEBS-NV was used to measure the tendency of eating behavior disorder and group interviews were conducted to compare the results by the level of eating behavior disorder. The results showed that “Methods related to Eating” were most frequently used regardless of the risk of abnormal eating behavior. Additionally, methods focused on body water regulation were commonly used in aesthetic competitions. Many athletes in the high-risk group reported feeling that they lacked control over their weight despite actively managing it. Future development of weight management guidelines for aesthetic sports could lead to a reduced risk of abnormal eating behavior in female athletes.

We investigated the effects of continuous static stretching on cognitive function, flexibility, anti-atherosclerosis in latter-stage elderly people. The cognitive function, flexibility, vascular endothelial function and arterial stiffness significantly improved after three and six months of intervention. However, after a 6-month period of no intervention, cognitive function, flexibility, vascular endothelial function, and arterial stiffness returned to pre-intervention levels, demonstrating the reversibility of the effects achieved. These results suggest that static stretching may contribute as an anti-atherosclerotic exercise in latter-stage elderly people, as it improves cognitive function, flexibility, vascular endothelial function and arterial stiffness. Key words：static stretching, cognitive function, flexibility, vascular endothelial function, arterial stiffness

Objective: The purpose of this study was to investigate the relationship between foot navicular height and motor ability in preschool children. Methods: Seventy-four (42 girls and 32 boys) 4- and 5-year-old children participated in this study. Foot geometry was measured by a three-dimensional foot-measuring device (INFOOT 2). Motor ability was assessed using six activities: 25m sprint, standing broad jump, tennis ball throw, two-legged continuous jump over, body support duration, and ball catch. Their performance in each activity was rated on a 5-point scale (1–5), as outlined in a previous Japanese study. Results and Discussion: Foot navicular height ratio was 11.0 ± 1.1 % in the 4-year-old girls, 11.2 ± 1.3 % in the 5-year-old girls, 12.4 ± 1.4 % in the 4-year-old boys, and 12.0 ± 1.6 % in the 5-year-old boys. Foot navicul height ratio in the 4-year-old boys was significantly higher than the 4-year-old girls (p<0.01). Partial correlation analysis between foot navicular height and motor ability, controlling for gender and age, showed no significant correlation. Conclusion: These findings suggest that foot navicular height is not related to motor ability with developmental growth and development in preschool children.
