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.

The loss of required thoracic spine ranges of motion for sport movements can be problematic for the elite athlete, as well as the weekend warrior. The purpose of this article is to explore biomechanical causes for thoracic mobility restriction as well as provide easily applicable techniques to restore mobility.

The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.

Learn from a coach who took his career from working with Winter Olympic and professional sport athletes to success in the private sector. In this episode, Bret Kelly of Exos and formerly United States Ski and Snowboard, shares about his journey and the need for coaches to remain versatile in growing their professional skills in the field. Tune in as Kelly connects with Eric McMahon, the NSCA Coaching and Sport Science Program Manager, on seeking out opportunities to work in niche Olympic sports, the growing uses of performance technology, and the value of building a strong support staff.

This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.

This article outlines a potential learning course intended for students in undergraduate criminal justice and homeland security majors to improve their physical health literacy and health-related behaviors.

The third and final article in this series will introduce the practical and technical elements of heart rate variability (HRV) monitoring in greater depth and detail.

The research reviewed in this article provides a baseline snapshot of clinically-relevant tools to screen, diagnose, and provide treatment that can improve behavior surrounding sleep, as well as quantity and quality of sleep in occupational firefighters.

This article discusses how suspension-based resistance training may help develop the stability and muscular endurance in the shoulder joint needed to decrease the risk of shoulder injuries as a result of the demands of firefighting.

Several obstacles can derail women from reaching or succeeding in the elite combat schools and will need to be mediated. The main obstacles this article focuses on are the current standard fitness requirements for attending an advanced combat school, the high absolute strength and power demands required by these combat schools, and the unique physiology of women compared to men.
