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.

Part 2 of this series on allostatic load theory will focus on how monitoring personnel holistically can contribute to a well-rounded health and performance model supporting the tactical athletes.

This article discusses how first responder organizations can optimize their training programs through scientific techniques, including the measurement of training load.

Law enforcement officers can experience psychological and physical stress in most of every part of their day, even starting from the first day of the academy. This article looks at Heart Rate Response in relation to stress, and interventions to manage stress through the academy.

HRV is thought to provide objective insight into understanding fatigue, “trainability,” and “readiness” to perform in athletic populations. Evolving access to HRV data may enhance the understanding of individualized fitness and training responses in tactical athletes.

In recent years, performance and prevention strategies have grown to include monitoring training load (TL) to understand fatigue and the potential effects of fatigue on training adaptation and performance.

This article discusses performance under stress, as well as factors influencing this performance in tactical personnel.

This article will discuss specific measures of stress that can be monitored, as well as coping skills to mitigate the negative effects of stress.

No two days are the same for Will Gilmore as part of a team that oversees over 800 athletes across 200 sports at the Red Bull Athlete Performance Center. From surfers to skydivers, the facility provides an elite high-performance ecosystem for traditionally individual sport athletes. Gilmore highlights the need for remote programming and monitoring to support a constantly shifting roster. Together as a team, they navigate uncharted territory in action sports conditioning, guided by physiological demands and underlying energy systems. Gilmore and NSCA Coaching and Sport Science Program Manager Eric McMahon discuss the shift in sport science from ample to actionable data to find, change, and measure what matters most. Gilmore reflects on his “career periodization” and having free time for friends and family while working corporate hours — a stark contrast with his background in Major League Baseball (MLB). The pair also emphasize proactive networking and education for future career opportunities.
