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.
Explore the 2027 NSCA National Conference in Las Vegas and online, July 7–10, the definitive event for strength and conditioning education. See 2026 highlights.
The National Strength and Conditioning Association was founded in 1978 with 76 strength coaches from across the country with the common desire to network, collaborate and unify the profession of strength and conditioning. Since its inception, the NSCA has grown to nearly 30,000 members in 72 countries and become the leader in the research and education of strength and conditioning professionals. Take a tour of the NSCA’s past and learn more about how it became the institution that it is today.
Velocity-based training (VBT) is an increasingly popular programming strategy used by strength and conditioning professionals to develop their athlete’s ability to express force rapidly. To implement the varying forms of VBT effectively within their training regimes, strength and conditioning professionals need to understand the strengths and weaknesses of strategies, such as predicting 1 repetition maximum using the load-velocity profile, modulating training loads using the load-velocity profile, and controlling training volume using the magnitude of velocity-loss. The aim of this review was to highlight these strengths and weaknesses and then provide practical examples of when each programming strategy may be most effectively implemented.
Since traditional sport-specific training or exercise programs do not create enough stimulus to improve the function of the respiratory muscles, the rationale to introduce respiratory muscle training (RMT) emerged. RMT is associated with improved endurance performance and pulmonary function, and it reduced respiratory fatigue, perceived exertion, or breathlessness. The purpose of this article is to provide coaches with tools to select the appropriate form of RMT in the context of the athletes’ needs, using appropriate methods, techniques, devices, and testing protocols.

This study aimed to analyze the time under tension (TUT) behavior in the bench press exercise performance in recreationally trained individuals. A systematic review was performed based on
the PRISMA recommendations and registered on PROSPERO (CRD42022301830). MEDLINE
(PubMed), Scopus, SPORTDiscus, and Lilacs (BVS) databases were consulted with the terms (resistance training [Title/Abstract]) OR (strength training [Title/Abstract]) AND (time under tension [Title/Abstract]). Cohort studies that analyzed the TUT in the bench press exercise in individuals with experience in resistance training were included. We used the Critical Appraisal Skills Program tool to analyze the methodological quality of the included studies. Thirteen studies met the inclusion criteria. The total number of participants was 215 individuals (179 men and 36 women). TUT was analyzed from the manipulation of each study variable. The behavior of the TUT in the bench press exercise
varies according to the training protocol and method used. The TUT and the number of repetitions can vary to quantify the training volume.
The Strength and Conditioning Journal is the professional journal for strength coaches, personal trainers, physical therapists, athletic trainers, and other health professionals working in the strength and conditioning field. The journal's mission is to publish articles that report both the practical applications of research findings and the knowledge gained by experienced professionals.
Eccentric resistance training has been shown to elicit beneficial effects on performance and injury prevention in sports because of its specific muscular and neural adaptations. Within the different methods used to generate eccentric overload, flywheel eccentric training has gained interest in recent years because of its advantages over other methods such as its portability, the ample exercise variety it allows and its accommodated resistance. Only a limited number of studies that use flywheel devices provide enough evidence to support the presence of eccentric overload. There is limited guidance on the practical implementation of flywheel eccentric training in the current literature. In this article, we provide literature to support the use of flywheel eccentric training and present practical guidelines to develop exercises that allow eccentric overload.
