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.
Netball is a team sport played worldwide. High-risk landing events containing biomechanical potential for noncontact knee soft-tissue injury (STI) occur frequently. Subsequently, noncontact knee STI is common after knee abduction collapse during landing tasks. Lower-limb mobility, strength, balance, movement, and hop test characteristics (intrinsic, modifiable risk factors) are associated with high-risk landing biomechanics and noncontact knee STI events. Such risk factors should be considered in netball-specific noncontact knee STI prevention preparticipation screening. Corresponding training methods should be included as indicated in netball-specific multimodal noncontact knee STI prevention programs. This article provides insight into noncontact knee injury–related aspects of netball and gives detailed suggestions for injury prevention screening and programming.
This article provides the first academic history of the barbell back squat and its evolution from a bodyweight exercise in the 19th century to a loaded exercise used for a variety of purposes in the present age. In doing so, the article highlights three key drivers in the evolution of the back squat—changes in equipment, the diversification of strength sports, and scientific communication concerning the safety and efficacy of the movement. The goal of this article was not to provide a dry and irrelevant history but rather to stress the complexity of the squat’s prominence within fitness programs and the need to hold a nuanced view toward the “optimal” way to approach this movement. It examines how the movement evolved from being primarily done on the tips of one’s toes, to a loaded movement on tippy toes, to a flat-footed movement. By contextualizing the back squat’s history, this article challenges rigid notions of “correct” squatting technique and encourages a more nuanced understanding of exercise selection in strength and conditioning practice. It concludes by highlighting the importance of critically examining the social construction of knowledge in fitness and sport, and the value of historical perspective in informing contemporary training practices
