The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.

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.

The purpose of this article is to present normative data that has been previously collected for the 75PR, use the data to create informed training practices, and support the need for further research of this particular topic in law enforcement.

This article breaks down periodization into sequencing and integrating training factors to optimize training outcomes.

This excerpt from Developing Speed demonstrates a fun drill aimed to develop the ability to make a cut step in response to a stimulus and to accelerate from this direction change.

The extent to which a special operator’s training schedule can be planned in advance is often limited due to their unpredictable operational demands. However, there may be opportunities to plan for specific training during certain periods.

This article examines how training the core and performance are connected. This article seeks to help propose how to best use the literature to maximize understanding and use of the current concepts.

Sheri Walters’ journey to Director of Sports Medicine at Texas A&M University reflects a career defined by innovation, collaboration, and comprehensive integration. Walters discusses the "arms race" in collegiate athletics and how Texas A&M shatters silos through unit alignment and being intentionally present. Drawing from her EXOS experience, she highlights the impact of integrating sports medicine with strength and conditioning. Walters employs research-based cross-body training to maintain strength, prioritizing long-term rehabilitation over limb symmetry index testing. She explains how her Certified Strength and Conditioning Specialist® (CSCS®) and Certified Performance and Sport Scientist® (CPSS®) credentials enable her to elevate rehabilitation and speak the language of sport performance professionals. Walters underscores the importance of getting student-athletes back to team strength and conditioning as soon as tissues can tolerate it to promote physiological and psychological healing. She also shares how strength and conditioning coaches can optimize return to performance and reduce reinjury risk.
