摘要：Clayton MA, Trudo, CE, Laubach LL, Linderman JK, De Marco GM, Barr S. Relationships Between Isokinetic Core Strength and Athletic Performance Tests in Male Collegiate Baseball Players. JEPonline 2011;15(5):20-30. Core strength and its relation to sport performance is a focal point of athletic training programs. The purpose of this study was to determine the relationships between isokinetic core strength and multiple measures of athletic performance in male collegiate baseball athletes. Subjects included 29 male collegiate baseball players (20.4 ± 1.6 yrs). All subjects participated in 5 data collection sessions, including 2 familiarization meetings. Data collection included measures of body composition, athletic performance tests, and isokinetic core strength. The primary finding of this research was that the Backwards Overhead Medicine Ball (BOMB) throw consistently produced significant correlations with all measures of isokinetic core strength, with the highest correlation observed between the BOMB throw and trunk flexion (r = .680; P=0.05). Statistically significant relationships were also found between trunk flexion and body weight, BMI, BodPod percent body fat, fat weight, and body weight. The complexity of core musculature must be considered when selecting assessments of core strength, with special attention to their impact on sport specific movements.
