In this video from the NSCA's 2013 Personal Trainer Conference, Chad Waterbury discusses how to maximize motor unit recruitment. Chad discusses three ways to recruit more motor units - lift heavy, accelerate sub-maximal loads, and train with high-tension movements.

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.

This NSCA Coach article discusses training modalities in bench press training and incorporating accessories to improve rate of force development (RFD) among athletes. Visit NSCA online to read more on strength training and exercise science.

This article briefly explains the two principles necessary for muscle growth.

An emerging body of research has explored the potential ergogenic effects of noninvasive interset recovery strategies involving the application of cold substances to the extremities distal to exercising muscles (e.g., palms of the hands or the soles of the feet). It was suggested that such strategies may acutely enhance resistance training (RT) performance by augmenting excitation and motor unit recruitment of the working muscles through enhanced stimulation of the central nervous system, resulting in greater force production and the ability to perform more repetitions to fatigue. Moreover, peripheral stimuli such as distal cooling may acutely reduce the sensation of distress during RT, allowing individuals to tolerate more exercise and achieve higher training volumes. Although there is some evidence that interset distal cooling confers an ergogenic benefit during RT, certain methodological considerations, a paucity of longitudinal research, and contrasting findings call into question its effectiveness. Thus, the purpose of this review is to assess the current evidence regarding the effects of interset palm and sole cooling on RT performance outcomes.

The expression of mechanical “muscle power” and the advanced training methodologies used to optimize it are explained by Duncan French in this session from the 2015 NSCA National Conference. By overviewing training strategies utilized with world-class athletes, this session links science with advanced training techniques designed to augment muscle power.

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.

This article provides a brief overview of literature where regional hypertrophy was reported. It also discusses the basic science and application of regional hypertrophy training.

The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.
