Joe Kenn, MA, CSCS,*D, RSCC, spoke at the NSCA's 2012 National Conference choosing the appropriate exercises to develop athletes and design programs.

The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.

This continuing education opportunity explores a variety of topics as they pertain to exercise technique. To earn your CEUs, it will be necessary to review several articles and pass a 50-question quiz. Please note: this quiz awards 1.0 CEU (10 contact hours).

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.

Jay DeMayo, strength and conditioning coach at the University of Richmond, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about training within a system but having flexibly, empowering athletes to make decisions in workouts, staying at one institution for 15+ years, books every coach should read, and knowing your role within the team setting.

This 2018 Personal Trainers Conference video features Lee Boyce going over the subject of anthropometry and the mechanics of the fundamental movements in strength training. Boyce describes the common issues you see and how to individualize movements for your clients.

This infographic explains how to build a load-velocity profile for velocity-based training (VBT), and is the second of a three part series explaining the theory behind and application of VBT.

This article provides a first-hand account of the usage and benefits of dumbbell training programs with athletes.

The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.
