This article provides a discussion around the evidence on creatine timing and supplementation.

J. Aggabao, former Assistant Strength Coach for the Los Angeles Rams of the National Football League (NFL), talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about coaching in the NFL. Topics under discussion include getting a foot in the door in the NFL, what happens when your head coach gets let go, and misconceptions about being an NFL strength coach.

The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.

This article presents the shoulder taps, which could serve as a more time-efficient screening tool for tactical operators. Although this article will present the shoulder taps as an assessment modality, it may be expanded upon and prescribed as an exercise for the purpose of improving trunk, hip, and shoulder stability.

This excerpt from NSCA’s Guide to Sport and Exercise Nutrition briefly analyzes some of the research behind creatine and its application to sport performance.

Dietary fat has both long-term and short-term effects on an athlete and athletic performance. “Fat loading” as a strategy to improve athletic performance remains unproven.

Ground-based free weight lifts, especially the explosive Olympic-style lifts, are highly recommended for athletic conditioning for the core muscles. They can provide a moderately unstable stimulus to augment activation of the core and limb muscles, while still providing maximal or near maximal strength, velocity, and power output.

Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.

This excerpt provides a brief snapshot of the use of carbohydrates in resistance training exercise sessions.

The effects of alcohol on athletic performance vary depending on quantity, demographics, and type of exercise, making it difficult to determine specific recommendations. From an athletic performance standpoint, the acute use of alcohol can influence motor skills, hydration status, aerobic performance, as well as aspects of the recovery process.
