Resumen
This research examined the acute effects of wearable resistance (WR) placed above and below the elbow of the throwing arm of baseball pitchers on throwing characteristics. Ten high school or collegiate baseball pitchers (19.5 +/- 2.4 years) performed a randomized throwing assessment with and without WR (100, 150, and 200 g) secured to the throwing arm above and below the elbow. Subjects wore an inertial sensor at the elbow to record arm speed; throwing velocity was measured by radar and temporal aspects (stride phase and pitch phase) measured by video. A repeated-measures ANOVA with post hoc analyses was used to test the influence of load magnitude and placement, with statistical significance set at p < 0.05. On average, loading significantly influenced arm speed and throwing velocity ( = 0.32-0.41, p < 0.05), and the effect of loading varied by placement (i.e., above and below elbow) for the latter)
