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.

This article discusses the influence of lower-body power on soccer performance in collegiate female soccer players. It also covers testing for muscular power qualities, different training modalities to use, and sample training programs as examples.

This article discusses the importance of upper body power training for protective security personnel and its potential for an occupational performance marker.

This article consists of five assessments that could be utilized by the tactical facilitator to measure upper- , lower- , and total-body power in law enforcement officers (LEOs). Although the focus of this article is LEOs, the assessments could also be used for other tactical populations.

This excerpt from Developing Power breaks down the step-by-step technique to a power clean from the hang position.

The purpose of this article is to describe the 165-lb body drag as performed by California law enforcement recruits in order to graduate academy.

This article explains the connections between the upper and lower body and their influence on performance and recovery strategies in sprinting.

This excerpt from Developing Power discusses implementing plyometric training in a program to develop lower body power.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

This book excerpt provides a step-by-step breakdown of the movements of the power snatch, from the starting position to the downward movement.
