This is an excerpt from NSCA's Essentials of Sport Science by NSCA -National Strength & Conditioning Association, Duncan N. French & Lorena Torres-Ronda.

Acceleration and maximal velocity are two factors that are key for any position in football and can determine success in many situations out on the field. This article will review several aspects of sprint mechanics and training to enhance linear (straight-ahead) speed for football players.

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.

This excerpt from NSCA’s Essentials of Sport Science briefly explains workload and injury risk factors.

This article discusses the influence of lower-body power on soccer performance in collegiate female soccer players. It also covers testing for muscular power qualities, different training modalities to use, and sample training programs as examples.

Catch up on this presentation from the 2024 NSCA Coaches Conference with Major League Baseball (MLB) Tampa Bay Rays Strength and Conditioning Coach, Joey Greany. Greany takes NSCA Coaching Program Manager, Eric McMahon, on a deep dive into plyometrics for a wide range of athletes. He also shares the importance of professional development for strength and conditioning coaches. Tune in to learn in-season training tips and how the NSCA inspired Greany’s path to the Big Leagues.

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. Learn how to build sport science systems, turn insights into action, and keep progressing on your professional path.

This excerpt from NSCA’s Essentials of Sport Science describes strength as a velocity-dependent concept.

Learn the basics of conducting a needs analysis for tactical athletes based on the athlete’s goals and desired outcomes, assessments, limitations on workout frequency and duration, equipment availability, health and injury status, and occupational physiological demands.
