Bryan Mann, from the University of Missouri, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about the future of velocity-based training, work-life balance, and getting a PhD while being a full-time strength and conditioning coach.
The snatch is one of the most technically demanding competitive movements. This article focuses on barbell trajectory (or bar path), motor control, and the height of the bar relative to the athlete’s body.
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.
Weightlifting is a highly technical sport that is governed by interactions of phases to optimize the load lifted. Given the technicality of the snatch and the clean and jerk, understanding key stable components to identify errors and better prescribe relevant exercises are warranted. The aim of this article is to present an applied method of analysis for coaches that considers the biomechanical underpinnings of optimal technique through stable interactions of the kinetics and kinematics of the lifter and barbell at key phases of the lift. This article will also look to discuss variable components that may differentiate between athletes and therefore provide a foundation in what to identify when coaching weightlifting to optimize load lifted while allowing for individual variances.
One method that is becoming increasingly popular for building strength, stability, and power in the shoulder joint is the use of barbells attached to a stable base known as a “landmine.”
