Abstract Taniyama, D, Matsuno, J, Yoshida, K, Pyle, B, and Nyland, J. Rotational medicine
ball throw velocity relates to NCAA Division III college baseball player bat swing, batted …

Background Baseball pitching performance can be mechanically explained by the
summation of speed principle and the principle of optimal coordination of partial momenta …

Background: Previous pilot research has investigated differences in elbow valgus torque
between the “tall and fall”(TF) and “drop and drive”(DD) pitching styles. Whether one of …

Several studies have identified body roll as an important variable that affects shoulder pain
due to its potential to modify upper limb kinematics. This study aimed to investigate potential …

Background Softball pitching is a ballistic, complex movement that requires an underhand
windmill motion to create force and ball velocity. In addition to proper pitch biomechanics …

Context: Following a baseball pitching bout, changes can occur to glenohumeral range of
motion that could be linked to injury. These effects are in part due to the posterior shoulder's …

Throwing ball velocity is one of the indicators that determine softball performance. However,
most of the training on throwing only focused on the major muscles and they neglected the …

momentum generation associations to fastball velocity performance among Division I …

Background Because the throwing motion can be considered a kinetic chain, pelvic and
trunk motion should be included in the analysis. Early pelvic rotation during the throwing …

Background: It has previously been speculated that baseball pitchers who display excessive
forearm pronation at foot contact (FC) have a higher propensity toward ulnar collateral …
