The purpose of this article is to give an overview and theoretical framework on the concept of periodized nutrition—with an emphasis on adequate carbohydrate intake to enhance performance.

This NSCA Coach article examines strength and conditioning strategies for collegiate distance runners to build performance for outdoor competition. Visit NSCA online to read about sport science.

This excerpt from NSCA’s Guide to Sport and Exercise Nutrition discusses the research surrounding the timing of hydration and its impact on sport performance for those participating in aerobic endurance exercise.

A sound year-round aerobic endurance training program should be divided into sport seasons with specific goals and objectives designed to improve performance gradually and progressively.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

Since traditional sport-specific training or exercise programs do not create enough stimulus to improve the function of the respiratory muscles, the rationale to introduce respiratory muscle training (RMT) emerged. RMT is associated with improved endurance performance and pulmonary function, and it reduced respiratory fatigue, perceived exertion, or breathlessness. The purpose of this article is to provide coaches with tools to select the appropriate form of RMT in the context of the athletes’ needs, using appropriate methods, techniques, devices, and testing protocols. The video abstract is presented in Supplemental Digital Content as SDC 1

This study compared the effectiveness of the single-leg Roman chair hold exercise with the Nordic hamstring curl exercise in athletes with previous hamstring injuries.

Fitness testing uses a battery of protocols recognized by the scientific community as both reliable and valid, and it measures important fitness constructs such as aerobic endurance, muscular strength, muscular endurance, power, agility, flexibility, and balance.

This excerpt from NSCA’s Essential of Tactical Strength and Conditioning explores the neural and muscular adaptations to training over time.
