This article aims to provide a good understanding of sleep health and the way it affects high performance populations.

Knowing when to train and how much time to devote to training each of the three energy systems is an important ingredient of success in endurance sports. This knowledge is also reflected in a well-designed and scientifically-based training plan.

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

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.

This article addresses three main areas of resistance exercise that best prepares tactical personnel for load carriage.

This article discusses overtraining risk factors in endurance athletes and provides strategies for optimizing effective programming. Visit NSCA online to learn more about athletic performance.

There is growing evidence that polarized endurance training is a promising method for optimizing a tactical athlete’s cardiovascular system, preparing for physical performance tests, allowing for a more full recovery during deployment, and allowing for safer return to duty after injury or deployment.

This book excerpt discusses how to maximize sprint quality during training sessions.

The aim of this study was to determine the effects of two different durations of training cessation on upper and lower body maximal strength performance, and to investigate the mechanisms underlying performance changes following short-term training cessation.
