Purpose: We examined the associations between anaerobic power, maximal strength, and isokinetic strength in Korean National snowboarders. Methods: We examined cross-sectional associations between isokinetic trunk strength in 89 Korean National snowboarders (mean age: 22.17 ± 4.82 years). The main outcome measures were the Wingate anaerobic power test, maximal strength test, and isokinetic knee strength test. Results: Isokinetic trunk strength was correlated with anaerobic power (lower average power, peak power, and power-drop rate). Further, trunk strength flexion and extension were significantly associated with maximal strength (knee strength and one-repetition maximum). Conclusions: The Korean national snowboarders` anaerobic capacity and maximal muscle strength measurements were positively associated with their isokinetic trunk strength. Further research is needed to elucidate the core balance and muscle-growth mechanisms underlying this association; ideally, future studies will involve exercise and treatment interventions to identify causal relationships.
