This article examines firefighter knee injury risk factors, screening tools, and strength and conditioning strategies to support injury prevention and return to duty. Visit NSCA online to learn more about strength training for firefighters.

The purpose of this article is to provide an introduction to contrast training, including how it is defined, what variables are utilized, and examples of how to use it in training.

Almost all functional movements of the trunk are combinations or variations of four basic movement patterns: trunk flexion, trunk extension, trunk rotation, and trunk lateral flexion. This article lists exercises to address each of these movement patterns.

Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

Developing Power brings an explosive take on the push-up and explains the technique behind the depth-drop push-up for upper body power development.

This article seeks to explain monitoring body composition, including how to assess it properly for an accurate evaluation to minimize errors in body fat estimation and maximize physical training.

The Dirty World of Triathlon: Training and Racing Demands of Xterra

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.

This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance training.

The purpose of this article is to discuss the theory behind the French Contrast Method (FCM), current evidence demonstrating its effectiveness, as well as proper implementation and execution for athletic populations.
