If manipulation of the training variables is not tailored correctly to the desired adaptations and specific training goals, an athlete can experience symptoms of nonfunctional overreach. If this process continues, the athlete can develop overtraining syndrome.

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.

The ability to manage the adaptive response, handle accumulated fatigue, and capitalize on the aftereffects established from training is central to the training process.

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.

This article discusses the effects of instability on force and velocity throughout the body.

This article features the recharge skate—an in-season hockey conditioning drill, designed by the authors, to maintain hockey-specific energy system fitness throughout the competitive season.

This brief excerpt breaks down agility into different target movement patterns to help develop an effective agility and quickness program.

This book excerpt provides examples of quickness drills that may improve the ability to identify a specific stimulus and to respond quickly and appropriately.

A fundamental training program at a young age gives the athlete the opportunity to develop many skills needed to succeed. The implementation of agility and coordination training can help reduce the risk of injury and elevate a young developing athlete.

The purpose of this article is to present normative data that has been previously collected for the 75PR, use the data to create informed training practices, and support the need for further research of this particular topic in law enforcement.
