Magnitude and time delay in hormonal responses to load

Magnitude and time delay in  hormonal responses to load

Case example: Weightlifter, male

Athlete profile: John, an aspiring weightlifter aiming for competitive success. This is a single case (n=1), described as observed.

Scenario: John and his coach measure the magnitude and timing of his hormonal response to differing training loads, and use what they measure to adjust his workouts.

By varying the intensity, duration and type of training and measuring the hormonal effect of those variations over a longer period, John and his coach build a record of how John individually responds to exercise stress. His training is then adjusted against that record — how hard he pushes, and how much recovery he takes.

Finding: In this one case, hormonal measurement gave the athlete and coach a concrete record of his own responses to work from when planning training. Nothing is generalised from a single athlete.

Single maintenance and adaptive workouts, followed by extended recovery

Single maintenance and adaptive workouts, followed by extended recovery, showing the typical response to differing load levels.

The harder, adaptive workout disrupts the body's homeostasis for an extended period of time. The suppressed anabolism takes on average 2–3 days of recovery before anabolic hormones rebound fully. Continued heavy training over 2–3 days can extend the recovery needed to 4–7 days before the same rebound appears.

The magnitude and timing of the hormonal response to workouts varies based on several factors, including the intensity, duration, and type of training load, as well as individual variation, nutritional factors, recovery status and training goals.

Measuring those variations over a longer period gives results describing how one body adapts to exercise stress — which is the thing training adaptations are read against.
