The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

From tactical strength and conditioning to developing the skills to train a specialized group of football kickers, Catherine Wallace shares how growing up in a military family inspired her into coaching. In this episode, Wallace connects with NSCA Coaching and Sport Science Program Manager, Eric McMahon, on how to pursue a tactical coaching career in different branches of the military and public safety. She discusses how earning the Tactical Strength and Conditioning Facilitator® (TSAC-F®) certification led her to pursue the Certified Strength and Conditioning Specialist® (CSCS®), and more ways that involvement with the NSCA has positioned her for career growth. There is also a discussion about “holistic programs” within strength and conditioning, an area that has been popularized, but is perhaps still misunderstood. Listen and learn about the rapidly growing tactical strength and conditioning area of the field, and the mindset needed to thrive as an impactful coach.

Occupational police tests described in the literature can serve as indicators of the occupational performance of their employees. In addition, practitioners in charge of police training should develop and employ obstacle courses composed of critical work tasks, as they may be strongly related to tests of aerobic endurance, strength, muscular endurance, and agility.
