The first in a planned article series to review essential considerations of each Functional Movement Screen (FMS™) pattern, this article will examine the FMS active straight leg raise (ASLR).

Interlimb asymmetries have been recently investigated in athletic populations. However, the effects of training interventions on interlimb asymmetries have been scarcely examined. Therefore, the aim of this study was to determine the effects of training interventions on changes in interlimb asymmetries from pre- to post-training. Furthermore, to examine the effects of training programs on intervention groups compared with control groups. A database search was completed (MEDLINE, CINAHL, and SPORTDiscus). Eight studies were then included in the meta-analysis. Results showed small reductions in interlimb asymmetries in single-leg broad jump (SLBJ) and change of direction (COD) speed from pre- to post-training interventions, whereas moderate effects were found in single-leg countermovement jump (SLCMJ) and SL lateral jump. When comparing the training interventions with the control groups, results showed small effects in favor of the training groups for reducing interlimb asymmetries in SLBJ and large effects in SLCMJ and COD speed. Thus, training interventions can evoke small to moderate reductions in interlimb asymmetries from pre- to post-training programs. Strength training performed unilaterally or bilaterally may elicit these reductions. Furthermore, training interventions showed larger effects compared with the control groups in reducing interlimb asymmetries. However, further research is needed.

This excerpt from NSCA’s Essentials of Personal Training discusses the importance of education on proper running surfaces, appropriate footwear, and the benefits of cross-training in addressing overuse of the knee.

The variables of an NBA season constantly change, which requires strength and conditioning coaches to adjust accordingly. The success of a program is often influenced by the coach’s ability to combine strength and conditioning principles with common sense and the ability to adjust to the schedule.

Line drills can be an excellent way for athletes to improve their footwork, speed, and coordination. This article contains examples of several easy-to-implement line drills.

This article seeks to help simplify the exercise selection process by providing clarity on how different exercises can aid in enhancing performance and potentially reduce injury risk.

For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60–1808 turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (608) and inside leg turns (1808). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.

This study compared the effectiveness of the single-leg Roman chair hold exercise with the Nordic hamstring curl exercise in athletes with previous hamstring injuries.
