摘要: The aim of the study was to examine relationship between pitching ball velocity and segmental (trunk, upper arm, forearm, leg, lower leg) whole-body muscle volume (MV) in high school baseball pitchers. Forty-seven male pitchers (40 right-handers seven left-handers; age, 16.2 ± 0.7 years; stature, 173.6 4.9 cm; mass, 65.0 6.8 kg, years experience, 7.5 1.8 maximum velocity, 119.0 9.0 km/hour) participated study. Segmental MV were measured using bioelectrical impedance analysis. Maximum with a sports radar gun. dominant arm significantly larger than non-dominant (P < 0.001). There no difference legs. Whole-body correlated (r = 0.412, P 0.01). Trunk not but for both legs, forearm 0.05). results affected by age or experience. are associated However, contribution mass on is limited, thus other fundamental factors (ie, skill) also important.
