This article explains the use of structured functional fitness programs for injury prevention and enhanced job performance in fire service personnel.

Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.

This article addresses possible benefits, proposed mechanisms, dosage, and frequency of beetroot juice as an ergogenic aid.

Repeated sprint ability (RSA) may be one of the most important factors to consider when developing strength and conditioning programs for high-intensity repeated sprint sports. In this session from the NSCA’s 2016 Coaches Conference, Ernie Rimer reviews the latest science behind RSA, compares the pros and cons of RSA protocols performed in the laboratory and in the field, and suggests methods to improve RSA.

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.

Monitoring training load is essential for determining if athletes are adapting positively or negatively to their training program. This article goes over the various measurement metrics and includes recommendations to monitor training load for football athletes.

This excerpt from NSCA's Essentials of Tactical Strength and Conditioning aims to educate on some fundamentals of energy systems training in tactical personnel.

In this session from the 2015 NSCA National Conference, Nelson Ayotte—the Strength and Conditioning Coach for the St. Louis Blues National Hockey League (NHL) team—explains how to design and implement a specific energy systems program at the elite level. Ayotte demonstrates the characteristics of each of the three energy systems and their trainability, and explores how to understand the energy demands of a sport by analysis of its characteristics, competition intensity, and duration of efforts and recovery periods.

Military and law enforcement needs analyses are not specifically matched to firefighting, but those training styles are better than basic fitness regimens or no regimen at all. For firefighters who are attracted to other styles of training not specific to firefighting, there are ways to train for all the demands of firefighting without making the firefighter use training modalities that they dislike or are not comfortable using.
