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 aims to describe the development of the sport scientist role and clarify the common qualifications and responsibilities therein.

The purpose of this article is to compare the effects of quarter, parallel, and full depth squats on muscle activity, joint stress, athletic abilities, and potential injury risks for the consideration of all strength and conditioning professionals.

Much in the same way that a single movement or a single workout does not make or break a training cycle, the same holds true for mental skills. The challenge is that the strength and conditioning coach will likely need to reach out to another professional trained in sport psychology to help establish the plan and construct the appropriate interventions.

Carmen Colomer, Director of Sport Science for the Philadelphia 76ers National Basketball Association (NBA) team, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about translating numbers into actions. Topics under discussion include periodizing athlete’s recovery in the NBA and how learning to code can help with data analysis and application.

Two factors that determine running speed are stride cadence and stride length. Because athletes propel themselves forward only when their foot is in contact with the ground, the stance phase of the running stride should be the focus of speed enhancement programs.

Emerging evidence suggests that omega-3 fatty acids may play a beneficial role in preservation of, and increases in, skeletal muscle mass. This is of particular relevance to the elderly who display age-related declines in muscle mass and function.

This article seeks to explain the differences between males and females in training and adaptations, as well as provide actionable guidelines to improve performance.
