A study was conducted to investigate the influence of kendo exercise on the bone mineral density in male and female university kendo athletes. The subjects were 45 male university kendo athletes and 23 female university kendo athletes. They had an average kendo experience of 13.2 years and 10.0 years. Measurements were performed using an AOS100 (ALOKA Corp.). We measured the speed of sound (SOS), transmission index (TI), and osteo sonoassessment index (OSI). The mean values of SOS, TI, and OSI in male and female university kendo athletes were higher than in the same aged control group and the peak bone mass aged control group.The values of the left heel were significantly higher than that of the right heel in bone mineral density. Body weight was significantly related to bone mineral density in male and female university kendo athletes. These results suggest that regular kendo exercise during youth is effective for the increase in bone mineral density.

The location of the stance during the standard position (Chudan-no-kamae) in Kendo measured from skilled Kendo players (n=28) were divided in the two types, high grade type (=HG) and middle grade type (=MG), according to the trained career (=Dan-i and playing career) of them. The length, width and left foot angle made from vertical line estimated from the location of the stance were compared between HG and MG. The differences of equilibrium between HG and MG were studied in student Kendo players (n=10). The parameters of equilibrium determined by analyzing the center of the foot pressure were the displacement of the body sway and the body sway area. These parameters were compared between HG and MG. The length of the stance (cm/Height) was shorter significantly (p< 0.05) in HG (=0.12±0.03)than in MG (=0.15±0.05). In the width and left foot angle of the stance, there was no difference between HG and MG, respectively. The displacement of the body sway was shorter significantly (p< 0.01) in HG than in MG. As the total period kept standing, mean value of the displacement in HG (=716.6mm) was 14% shorter than in MG (=830.6mm). In the body sway area, there was no difference between HG (=28.9± 13.1cm2) and MG (=30.9 ± 17.0cm2). These results suggest that the equilibrium in Kendo posture correlate closely with the length of stance. In the present paper, correlation between biomechanical properties of the different stance types in Kendo players and skill levels of them are also discussed.

高齢者の生活の自立と労働をめぐる問題をコミュニティにおける生活の自立システムを構築するという観点から研究を行い、次のような成果が得られた。コミュニティにおける生活のサステナビリティの構築には、(1)多様な人と連帯できる労働の場の確保をめざした地域の自立が重要である。(2)持続的再生産可能な地域資源作りとそれを活かしたコミュニティの再生が重要である。(3)福山市ではその一つとして市街地農業の活性化が重要な役割を担っていると考えられる。
