高校相撲選手の肩周囲筋力についての考察 Muscle Strength around the Shoulders in High School Sumo Wrestlers
We examined high school sumo wrestlers in order to study the relationship between their sport performance and the muscle strength around their shoulders.<BR>Materials and methods: Sixteen wrestlers were examined in 1998. The isometric strength of their internal and external rotators were measured using a Micro-FET(M), and the isokinetic strength of their internal (IR) and external rotators (ER) and flexor (FX) and extensor (EX) were measured using a Cybex(C). We also divided them into two groups; strong group (S) and weak group (W). Results: Their mean height was 175.9 cm, weight 99.5 kg, body mass index 32.1 kg/m2. In C, their FX and IR of S was significantly larger than those of W, but the ratio of EX and ER to their weight between S and W had no significant difference. IR increased more than EX for about 6 months. Conclusion: To improve their sport performance in high school sumo wrestlers, it was significant to increase their FX and IR, especially.
