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.

By implementing a fitness assessment, a law enforcement agency can assess its officers and gather important data. As long as there are support mechanisms in place to assist the “at risk” officers—such as access to physical training instructors, occupational health professionals, or dietitians—the organization can ensure that its officers move towards becoming a healthier and more resilient workforce.

Studies support the use of kettlebells for improving power, although evidence for using them to improve strength and aerobic fitness is still equivocal. Studies investigating the biomechanical properties of kettlebell training have been fruitful, and it may be useful for developing sprint running performance and for injury prevention.

Ankle sprains are an extremely common injury of both sports and everyday life. In the post-rehabilitation setting, it is important to first identify and then address deficits in ankle, hip, and knee range of motion and strength.

This article discusses the background, statistics, mechanisms, timing, dosing, influences, and practical applications for the use of caffeine as an ergogenic aid.

Changing an Industry and Culture in Public Safety

The purpose of this article is to provide an example of a resistance training program for improving performance and reducing the possibility of injury for pickleball players.

As Director of Sport Science at the University of Nevada, Las Vegas (UNLV), Heather Farmer spearheads comprehensive integration efforts. This includes ensuring every stakeholder, from sport performance staff to academic advisors, has a seat at the table. Farmer also outlines developing an internship and graduate assistantship program to meet staffing needs and offer opportunities for practical experience. She recounts how leveraging relationships — not data — has been her key to scalability. Additionally, Farmer recognizes that to make an impact, she must meet athletes and sport coaches where they are, which she uncovers through “highlights” and “hurdles.” She suggests that sport scientists with strength and conditioning backgrounds, like herself, are uniquely equipped to excel due to their communication skills. Farmer and McMahon also discuss avoiding “analysis paralysis” and how to incorporate data to elevate the student-athlete experience — an unignorable factor as athletes bring an element of “self” in the age of name, image and likeness (NIL).

What does it take to become an award-winning Director of Strength and Conditioning in the National Football League (NFL)? Justin Lovett reveals the “we over me” mentality that guides his role with the Los Angeles Rams. Lovett reflects on receiving the 2024 NSCA Professional Strength and Conditioning Coach of the Year Award after being an NSCA Member for over 20 years. He draws parallels between working with high school and NFL athletes — where the desired training responses are the same and ability levels vary — making versatility key. Lovett also stresses the importance of finding clean and effective training methods to accommodate wear and tear in football athletes. He compares the Rams’ hiring philosophy to gathering “infinity stones,” emphasizing character attributes, culture alignment, and staff chemistry. Lovett and NSCA Coaching and Sport Science Program Manager Eric McMahon discuss progressing into leadership and the rise of performance director roles, as well as how to seek out career and networking opportunities.
