What is the underlying physiological rationale behind professional cyclists spending a significant amount of time training in zone 2, and how does this approach impact their overall performance and endurance in high-intensity events?
Is the emphasis on zone 2 training a deliberate attempt to optimize mitochondrial density, increase lactate threshold, and enhance fat metabolism, or are there other factors at play?
How does the prolonged exposure to moderate-intensity exercise in zone 2 influence the development of aerobic capacity, and what are the implications for anaerobic performance in shorter, more intense events?
Are there any specific periodization strategies or training phases where zone 2 training is prioritized, and how do coaches and athletes balance the need for high-intensity interval training with the benefits of prolonged zone 2 work?
What role does zone 2 training play in the recovery process, and how do athletes use this intensity to facilitate active recovery and rebuild their energy stores after high-intensity efforts?
