This article addresses low back pain in first responders by examining three relevant studies.

Knowing the risks of cold weather training is only half the battle. It is important to be familiar with a proper risk management strategy to help guide decision-making that can enhance safety and exercise performance.

The purpose of this article is to help both personal trainers and clients with seven main concepts within exercise physiology that will improve training effectiveness and assist in explaining the body’s response to exercise.

This article defines and reviews the allostatic load theory in tactical personnel.

The importance of recognizing a closed-chain activity lies in the fact that the motions of multiple joints are coupled. Weakness at any one joint will consequently limit performance of the entire movement.

This article explores the concept of how lifestyle behaviors encouraged at the high school-level could affect fitness during adulthood, with a focus on both sport and strength and conditioning participation.

A common obstacle to achieving recommended physical activity and desired training goals is time. This is true for recreationally trained adults and athletes, particularly at the collegiate level, where greater restrictions on practice time and training are in place. One possible solution is to implement time-saving and time efficient training routines and methods that may limit the amount of time needed to attain desired physiological adaptations—by decreasing the time needed to train and/or by increasing the frequency with which brief workouts are completed throughout the week (e.g., “microdosing”). To provide the most optimal training stimulus, the correct method must be used. Unfortunately, numerous terms describe routines and methods discussed in the current body of available literature, many of which may seem similar and lead to confusion. The purpose of this article is to outline the similarities and differences of the numerous timesaving and time-efficient training routines and methods. Ultimately, this article synthesizes the current research into practical recommendations as programming options for strength and conditioning coaches and personal trainers. The information provided may also serve as a foundation for future research opportunities in time-saving and time-efficient training.

This article discusses the variability in physical testing outcomes for law enforcement recruits based on the ambient temperatures and relative humidity present on test day.

Because habits are contextually linked, it is reasonable to suggest that modifying the environment may disrupt the habit process and allow conscious intention to guide behavior. This article focuses on providing practical recommendations to aid individuals with intentions to exercise and eat healthy to reach their goals in the face of undesirable habits.

The following article provides a simple guide to ruck training for the aging population.
