High Performance Physiology

After a short break for the holidays, Chris and Rob are back for their first episode of 2026 talking about deloads. There are two scenarios in which deloads are taken: planned and unplanned. Planned deloads are written into a training program when fatigue is expected to accumulate. Unplanned deloads are taken when fatigue accidentally accumulates.

Chris and Rob change the format for this episode. Rather than covering physiology and biomechanics and then talking about how that information guides strength training programs for athletic performance, they talk about their own experiences in training for a one arm chin up.

Continuing on from the previous episodes discussing vertical jumping and throwing, Chris and Rob break down the way in which we can support the sprinting movement through targeted strength training.

Building once again on previous episodes in which they talked about strength, speed, and power, the proximal to distal sequence, and vertical jumping, Chris and Rob now tackle how throwing and punching work, and discuss how to train to improve performance in those activities.

In this episode, Chris and Rob build on previous podcast discussions about strength, speed, and power as well as on the proximal to distal sequence to explain [1] how vertical jumping works, and [2] how we can structure training programs to improve vertical jump height.

In this episode, Chris and Rob introduce eccentric training, starting with the underlying physiological adaptations and then going on to provide some commentary on practical programming. Contrary to what you will likely hear elsewhere, the important (transferable) adaptations caused by eccentric training are peripheral and not neural.

In this episode, Chris and Rob introduce the stretch-shortening cycle and its underlying mechanisms, focusing on how it works in fast movements. This builds on previous episodes in which they talked about speed, power, strength, and the proximal to distal sequence. Learn more about how tendons work to store and release elastic energy in fast movements.

After covering the basics of strength, speed, and power, Chris and Rob now address how the proximal to distal sequence works. This is a key feature of human movement and has been observed in running, jumping, and throwing, as well as more complex activities. Understanding how it works is essential for interpreting the transfer of training to sporting performance.

Building on the previous episodes, Chris and Rob tackle the adaptations that contribute to increasing maximum speed in the context of athletic training. As always, Chris explains the physiology and Rob provides examples of how to implement that knowledge from the training programs that he is currently writing for his clients.

Chris and Rob walk through the major physiological adaptations that contribute to increases in maximum strength and give examples of how these adaptations can be stimulated by specific elements within a strength training program. Since maximum strength is an externally-measured outcome, it cannot be stimulated to increase directly. We must instead create a range of specific underlying adaptations, each of which have their own unique stimuli.
