Muscle Activation and Strength Training

June 1, 2017

Article

Periodization of training is based on the principle that different loads (e.g., light, moderate, or heavy) or power requirements recruit different types and numbers of motor units. Recruitment order is important from a practical standpoint for several reasons.

Neural Contributions to Muscle Growth

June 1, 2017

Article

Neural adaptations help mediate growth-related processes and the early increase in strength is attributable mainly to improved neural function. Along with neural changes, various aspects of the protein metabolism in the muscle are changing in the early phases of training.

Abstract submissions are open yearly from November to March (exact dates change annually). See the Abstract Submission and Presentation Guidelines for more information (below). Research abstract presentations are an opportunity to present current research findings to researchers and strength and conditioning professionals at the NSCA National Conference.

Body Mass Bias—Effects on Fitness Test and Tactical Performance

June 1, 2015

Article Members Only

Because fitness test results are part of performance evaluations, smaller service members have an advantage in terms of attaining promotions, despite evidence that suggests that greater body size, strength, power, and load carrying capacity is correlated with tactical performance.
