Multidirectional ground reaction forces (GRFs) and jump tests within baseball pitchers provide insight into athletic ability and coordination to produce lower-body force and power. Lower-body power is a biomechanical feature that denotes physiological capacity through dynamic and passive tissue stretch-shortening in transferring energy from the ground through the kinetic chain. Optimized lower-body power may lessen the magnitude of forces on the upper extremity. Insufficient lower-body power may create a greater risk of upper-body injury. Lower-body power and its relationship to ball velocity have been minimally investigated, yet some research points to a correlation between jumping ability and fastball velocity. Because pitching is unilateral, practitioners should consider unilateral jumps to determine the extent of bilateral asymmetry or stride to drive leg differences that can guide training to remediate deficiencies. The purposes of this brief review are to (a) examine factors that influence vertical jump performance among baseball players, (b) examine research on pitching multidirectional GRFs, and (c) examine literature concerning jump performances to baseball pitching performance. Collectively, this review can assist coaches and practitioners in lower-body power testing and training for baseball pitchers.

The use of exercise interventions to maximize athletes’ performance is a common practice in competitions. This systematic review aimed to compile research that explored the effectiveness of priming strategies to maximize physical performance in track and field. The literature search was conducted from PubMed and Scopus. One hundred eighty-two studies were assessed against the inclusion criteria: (a) minimum 1-year participation/competition experience; (b) randomized controlled trials with pre-post intervention outcomes; and (c) studies involving exercise interventions applied #6 hours before outcome measures were collected. Fifteen studies satisfied the criteria and were categorized according to the exercise interventions used (i.e., resistance training, plyometric/ ballistic training, resisted sprints, and modified warm-ups). Heavy-loaded resistance training (i.e., .85% 1 repetition maximum) and resisted sprints increased subsequent sprint performance. Plyometrics/ballistic training also positively impacted subsequent jumping (i.e., long jump) and throwing performance (i.e., shot put). Modified warm-ups (i.e., high-intensity sprints and heavier throwing implements) also improved subsequent running and throwing performance. Overall, exercise interventions performed at high intensity and low volume augment subsequent physical performance as close to 4 minutes before the event. However, a sufficient recovery interval must be considered for a positive performance response.
