What are the underlying physiological mechanisms that drive the shift in muscle recruitment patterns during prolonged Zone 2 training, and how do factors such as fatigue, altered proprioception, and changes in muscle fiber type contribute to this phenomenon?
Is it related to the prolonged low-intensity stress causing an adaptation in the muscle-tendon junction, leading to a more efficient energy production and a shift in the recruitment of muscle fibers from fast-twitch to slow-twitch, or is there another mechanism at play?
How do the changes in muscle recruitment patterns impact the overall efficiency and effectiveness of the training, and what are the implications for cyclists looking to optimize their performance in endurance events?
Can we attribute the shift in muscle recruitment patterns to the brains attempt to conserve energy and reduce the metabolic cost of cycling, or is it a result of the muscles intrinsic ability to adapt to the demands placed upon it?
Are there any specific training protocols or techniques that can be implemented to influence the shift in muscle recruitment patterns, and what are the potential benefits and drawbacks of doing so?
