| 内容記述 | The purpose of this study is to clarify the relationship between kick start performance and lower limb morphology, and between kick start performance and isokinetic strength of the knee joint in collegiate competitive swimmers. The subjects of this study were 25 male collegiate competitive swimmers. The subjects' specialties were breaststroke (n=6), butterfly (n=6), and crawl (n=13). The morphology of the lower limbs was measured in terms of skeletal muscle mass, thigh length, leg length, thigh circumference, and leg circumference. Lower limb muscle strength was measured using an isokinetic dynamometer to measure isokinetic knee joint muscle strength. The trials involved measuring maximum isokinetic strength in extension and flexion of the left and right knee joints (60deg/s, 120deg/s, and 180deg/s, three times each). Start performance was measured using a kick start. Each subject performed four trials in their specialty, swimming at maximum speed from the platform to the 15m point. The starting movement was filmed using a highspeed camera(240fps) placed beside the starting block. A digital video camera(60fps) was used to measure the 7.5m and 10m times. The analysis items were 7.5m time, 10m time, velocity at take-off, water entry distance, and water entry angle. As a result, in terms of the relationship between lower limb morphology and starting performance, significant negative correlations were found between 7.5m and 10m times and lower limb muscle mass (front and rear legs), leg length (front and rear legs), thigh circumference (front and rear legs), and leg circumference (front and rear legs). Entry distance was significantly positively correlated with lower limb muscle mass in the front and back legs, and leg length in the front and back legs. There was a significant positive correlation between velocity at take-off and lower limb muscle mass in the front and back legs, thigh circumference in the front and back legs, and lower leg circumference in the front and back legs. Regarding the relationship between lower limb strength and starting performance, a significant positive correlation was found between entry distance and the rear leg at 60 degree/s in the extensor muscles, the front leg at 120 degree/s, and the front leg at 120 degree/s in the flexor muscles. These results make it clear that knee isokinetic extension and flexion strength contribute to entry distance. This means that it will contribute to selecting training to improve starting performance. Furthermore, when measuring the morphology of the lower limbs, it is necessary to measure muscle mass when measuring circumference. |
