In this case, I showed him the path his elbow took in relation to his shoulders and told him to imagine them rotating on the same plane until release. Now, we’ve seen that his arm action could use some adjusting, but there are some steps to take when approaching making a change like this. This is really important–he throws directly in front of his face. Note where he’s throwing the ball in that first clip. We’ve seen, on average, elite throwers are more consistent with their shoulder abduction from front-foot contact to ball release-almost as if their elbows and shoulders rotate on the same plane as one another. Technically speaking, it is called a high shoulder abduction. Below is an example of how abduction is measured: Take, for example, this video taken from behind an athlete and consider how it gives us an idea of his arm action and, more specifically, where his elbow is in relation to his shoulders.Ī ‘high elbow climb’ can be defined as the humerus (upper arm) getting too high going into ball release. While the pivot pickoff is a key drill for remapping arm action, you can likely see high elbow climbs in nearly every drill. Each drill is designed for an athlete to focus on a particular part of the pitching motion. Trainer Perspective of High Elbow ClimbĪt Driveline, pitchers throw our constraint drills nearly every single day. This will be a good example of how you can combine biomechanics, assessments, and retesting with the knowledge of a throwing trainer in order to help make positive movement changes in your athletes.

Today, we’re discussing what we see from a training-floor perspective and a biomechanical assessment.

One piece of data that we occasionally see is pitchers with high elbow climbs. It is suggested that shoulder abduction and lateral trunk tilt may be only two of several determinants of peak elbow varus torque.Integrating assessment data to help athletes is vital to what we do at Driveline. As trunk tilt to the contralateral side increased, the shoulder abduction angle producing the minimum peak elbow varus torque decreased. Although regression analyses did not show any significant relationship, computer simulation indicated that the peak elbow varus torque was affected by both angles, and the interaction of those angles was also significant. Regression analyses of a simple regression model, second-order regression model, and multiple regression model were also performed. A two-way analysis of variance was performed to analyze the effects of shoulder abduction and trunk tilt on elbow varus torque. Forty-two simulated motions were generated for each pitcher, and the peak elbow varus torque for each simulated motion was calculated. Motion data were used for computer simulations in which two angles-shoulder abduction and lateral trunk tilt-were systematically altered. To examine the effects of shoulder abduction and lateral trunk tilt angles on elbow varus torque, we conducted simulation and regression analyses on 33 college baseball pitchers. Elbow varus torque is a primary factor in the risk of elbow injury during pitching.
