This article is the 12th in a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

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 is intended to provide an understanding of the demands of football from a bioenergetic perspective and provides a framework in which strength and conditioning professionals can design conditioning plans that focus on preparing athletes for competition.

Because fitness test results are part of performance evaluations, smaller service members have an advantage in terms of attaining promotions, despite evidence that suggests that greater body size, strength, power, and load carrying capacity is correlated with tactical performance.

The purpose of this article is to address the key elements when designing a training program for firefighters, provide evidence for utilizing circuit training, and suggest recommendations on how to incorporate circuit training into the training program.
