[Purpose]] We examined student sumo wrestlers in order to study the relationship between their sports performance and the muscle strength around their shoulders.[Materials and Methods] Twenty-three wrestlers were examined in 2000. Twelve were collegiate and eleven were high school wrestlers. The isokinetic strength of their internal (IR) and external (ER) rotators and flexor (FX) and extensor (EX) were measured using a Cybex. We also divided them into two groups : strong group and weak group. Strong group has higher sports performance than weak group in sumo wrestling.[Results] Their mean height was 177.6cm, weight 108.6kg, body mass index 34.3kg/m2. Their IR, ER, EX and FX of strong group was significantly larger than one of weak group, but the ratio of strength to their weight, the ratio of ER to IR and the ratio of FX to EX between strong group and weak group had no significant difference.[Conclusion] In order to improve their sports performance of student sumo wrestlers, it was significant to increase their IR, ER, FX and EX, especially.
