Studies support the use of kettlebells for improving power, although evidence for using them to improve strength and aerobic fitness is still equivocal. Studies investigating the biomechanical properties of kettlebell training have been fruitful, and it may be useful for developing sprint running performance and for injury prevention.

Research shows that the appropriate integration of resistance training into the endurance athlete’s training can result in significantly better performance when compared to classic endurance training plans that focus only on aerobic endurance.

This excerpt briefly describes key aspects of this nonessential amino acid including its effect on the body, efficacy, and adverse effects.

This article details the rationale for making the eight main movements the foundation of tactical strength and conditioning.

Sled exercises provide a training stimulus that closely mimics real-world physical demands of sports. This article provides examples of how to implement sled training into a program.

In this video from the 2023 NSCA National Conference, Duncan French discusses effective decision-making processes within strength and conditioning, and how coaches can identify, review, and improve training interventions for strength, power, and conditioning.

Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.

Learn about how a potentiating stimulus can induce a postactivation potentiation (PAP) response in vertical jump, sprint, and upper-body performance, as well as the optimal structure of a strength-power potentiating complex.

This excerpt from NSCA’s Essentials of Sport Science briefly explains the force-velocity-power profile and how it can give strength and conditioning coaches a more holistic view of athletes.

In addition to standard health, fitness, or sport assessment guidelines, several guidelines exist for the fire service. Since each agency is different in its preferences, capabilities, and philosophies, applying a standard recommendation may not be possible. This article introduces basic decision-making considerations for fire service assessment batteries.
