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.

What are strength, speed, and power? We call them athletic qualities but how are they actually improved? In this episode, Chris and Rob explain how strength and speed are each outcomes underpinned by specific, unique adaptations, while power is a second order outcome underpinned by strength and speed.
