Limb symmetry index in competitive alpine ski racers: Reference values and injury risk identification according to age-related performance levels

摘要

PurposeThe aims of this study were to assess differences of limb symmetry index (LSI) in strength- and coordination-related tasks between high-level, competitive, noninjured ski racers of different age-related performance levels and to prospectively assess limb differences as a possible risk factor for traumatic and overuse injury in youth ski racers.
