PMC Bethesda, MD 20894, Web Policies Considering that the quarterback throwing motion requires full-body motion involvement, we may assume that these physiological improvements would ultimately lead to throwing performance enhancement. One-way analysis of variance was used to determine the differences between the six throwing approaches for the kinetic and kinematic variables examined in this study. Although not evident in these data, it is likely to be apparent when making realistic throws on an actual field. In a study of pitchers with chronic anterior instability, stimulation of mechanoreceptors within the glenohumeral joint excited and/or inhibited certain muscles. The wind-up phase is defined as the initial movement to maximum knee lift of stride leg [3]. Some soccer injuries may be attributable to the equipment used. Youth football injuries. Please note that decreasing the distance away from the centre or decreasing the angle did not result in an increased anterior force on the shoulder. It is reported that about 50% of the velocity of the ball during an overhead throw is generated from step and body rotation. Standing still and throw (SST), one-step right left (1SRL), one-step left right (1SLR), three-step straight ahead (3SSA), three-step shot gun (3SSG), five-step throw (5ST). While no differences in ball throwing velocities were detected, our findings indicate significant differences in the drop step and throwing motion times between all of the examined approaches except between 1SLR and 1SRL.
