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.

The purpose of this meta-analysis was to synthesize the literature and provide a robust estimate of the correlations between lower-body, multijoint, isometric and dynamic neuromuscular assessment variables and snatch (SN) and clean and jerk (C&J) performance in competitive weightlifters. A comprehensive search through 3 electronic databases (PubMed, SPORTDiscus, and Web of Science) returned 12 studies that met the inclusion criteria. Meta-analyses were performed on Pearson’s correlations between SN and C&J performance and 15 variables from 5 neuromuscular assessments— countermovement jump (CMJ), squat jump (SJ), isometric midthigh pull (IMTP), back squat (BS), and front squat (FS) one repetition maximum (1RM). The FS and BS 1RM exhibited nearly perfect correlations (r 5 0.93 to 0.94), whereas the IMTP peak force exhibited very large correlations (r 5 0.83 to 0.85). The IMTP force at 250 ms exhibited very large correlations (r 5 0.77 to 0.78), and the CMJ and SJ peak power exhibited very large to nearly perfect correlations (r 5 0.88 to 0.92). These findings illustrate the importance of lower-body maximal and time-limited force-producing capabilities in weightlifters. Moreover, each assessment offers at least one variable that exhibits a correlation of .0.70. Therefore, these assessments may be used to gauge weightlifting performance potential.

This article briefly reviews the importance of the stretch-shortening cycle in power production.

Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power based movements.

In recent years, performance and prevention strategies have grown to include monitoring training load (TL) to understand fatigue and the potential effects of fatigue on training adaptation and performance.

Dr. Tim Suchomel, Assistant Professor at Carroll University and Wisconsin State Director for the NSCA, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the emerging role of sport science in strength and conditioning. Topics under discussion include Suchomel’s growing involvement with the NSCA, as well as weightlifting derivatives and their benefits for more individualized performance adaptations.

The purpose of this article is to compare the effects of quarter, parallel, and full depth squats on muscle activity, joint stress, athletic abilities, and potential injury risks for the consideration of all strength and conditioning professionals.

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

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 study investigated the differences in off-ice and on-ice fitness characteristics between elite and subelite male ice hockey players.
