Great S&C coaches do more than design programs—they lead people to achieve their best and most consistent performances.

Completion of the following assessment will renew your current status within the NSCA Registered Strength and Conditioning Coach (RSCC) Program

In this session from the NSCA's 2023 Personal Trainers Virtual Conference, Ashley Hodge, MBA, CSCS and owner of Ashley Hodge Fitness, discusses program design considerations for optimally building the glutes and discusses the biggest mistakes in glute training and how to avoid them.

This is the NSCA’s Coaching Podcast, where strength and conditioning coaches share their experience, lessons learned, and advice about how to thrive in a highly competitive profession.

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.
