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.

This article briefly describes how individuals can have the same training program, but have large fluctuations in the adaptation responses due to genetic and life style factors.

This article seeks to explain the differences between males and females in training and adaptations, as well as provide actionable guidelines to improve performance.

In this nutrition discussion from CEO and co-founder of the International Society of Sports Nutrition, Jose Antonio, identifies what a “high” intake of protein is for athlete; the risks, if any, for high protein intakes; the effects of high protein intakes on body composition; and the genes that may influence body composition.

In this session from the NSCA’s 2018 Personal Trainers Conference, Brad Schoenfeld talks about integrating science into training programs to optimize an individual’s genetic potential to see the best results from training.

Learn training principles for general physical preparation of swimmers, and understand how to utilize weekly planning to best aid in the expression of physical performance. Keenan Robinson also discusses how to differentiate between readiness strategies to best apply stress in this session from the NSCA’s 2017 National Conference.

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.

Maximal force can be expressed across a range of conditions influenced by the external load and the time available to express force. As a result, several distinct and specific strength qualities exist. Conversely, some expressions of maximal force are similar and can be categorized as a single quality. Therefore, strength assessment systems must be sophisticated enough to isolate and measure each quality while minimizing redundant information. This article presents a contemporary, evidence-based and practical framework that reduces the many strength and speed-strength metrics into 5 distinct qualities. Alongside this, we present case examples of the application of strength diagnosis.

Transitioning From the Single Discipline Fight Sport to MMA

The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.
