In the final part of this four-part series on proper movement, the author recommends that the US Marine Corps screen the movement quality of each Marine and educate them on how to move correctly in order to reduce the risk of injury.

This article provides an understanding of the role the core plays during execution of athletic movements, as well as provides evidence-based concepts that help to strengthen the core and maximize movement performance.

The goal of this article is to define some of the basic physiological responses to acute and chronic altitude exposure and to provide some evidence-based, practical guidelines when approaching training and racing at higher altitudes.

The purpose of this article is to address the key elements when designing a training program for firefighters, provide evidence for utilizing circuit training, and suggest recommendations on how to incorporate circuit training into the training program.

Joel Raether, owner of Authentic Performance in Denver, CO, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about how to get started and then progress as a strength and conditioning professional. Early on, it takes plenty of long hard hours to get to a high level in this profession, but as you find your way, you must find a balance between work and life. Developing relationships is the biggest part of moving forward and being successful with high level athletes.

Integrating weight room cues that are more consistent with those used to reinforce safer tackling techniques on the field may help with athlete retention and buy-in, and prevent potential confusion.

Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.

The ability to manage the adaptive response, handle accumulated fatigue, and capitalize on the aftereffects established from training is central to the training process.

The periodization of training is facilitated by a hierarchical structure that allows for several distinct interrelated levels that can be used in the planning process. Each level of the periodization process should be based on the training goals established for the athlete or team.
