Greg Haff, former President of the National Strength and Conditioning Association (NSCA), current course coordinator for post graduate studies in strength and conditioning at Edith Cowan University, and Senior Associate Editor for the Journal of Strength and Conditioning Research, talks to the NSCA’s Head Strength and Conditioning Coach, Scott Caulfield, about his journey through strength and conditioning and his efforts to progress the field during his time as president of the NSCA. Topics under discussion include: his years being NSCA Board of Director President, the future of the profession, how he got involved in the NSCA, key traits of icons in the field, traits for potential incoming students, and how to get into sports science.

This article is the second of a series of articles on strength training practices for rowing and seeks to provide information on periodization strategies for rowers of different competitive levels and schedules, as well as include sample periodization plans and sample programs.

Thank you for your willingness to evaluate and make a recommendation for the National Strength and Conditioning Association’s (NSCA’s) L.I.F.T. Mentorship Program. The purpose of this program is to prepare and position students and professional members from underrepresented groups for participation in NSCA activities that will lead to stronger leadership opportunities and outcomes. This program includes both online leadership mentoring with an NSCA professional as well as covered expenses for the applicant to attend NSCA’s National Conference.

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.

Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.
