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.

Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

This article reviews electromyography (EMG) procedures as well as provides examples of how EMG data analysis has been used in tactical populations.

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.

This article discusses the effects of instability on force and velocity throughout the body.

This article discusses using the principle of specificity as an important component in tactical training programs to enhance performance, decrease injuries, and improve functional longevity of a tactical athlete.

Understanding attentional styles can improve coaching effectiveness by allowing the coach to provide appropriate cues or methods for each athlete.

This Kinetic Select excerpt from the Essentials of Strength Training and Conditioning, Fourth Edition describes the results from electromyography (EMG) studies on the neural adaptations to anaerobic training.
