Is the notion that climbers should focus solely on high-intensity interval training (HIIT) during the base training phase a myth, or is there actually some scientific basis behind it? Whats the optimal ratio of HIIT to steady-state training for a climber looking to improve their lactate threshold, and are there any specific workouts or protocols that have been proven to be more effective than others in terms of building sustainable power output? Would a 2:1 or 3:1 ratio of steady-state:HIIT be a more effective way to build endurance, or would that not be enough to elicit the necessary physiological adaptations? Should climbers even bother with low-cadence, high-torque workouts, or are those a waste of time when it comes to building actual power output? Are there any studies or scientific research that support the idea that a specific weekly workout schedule or protocol can actually improve a climbers performance on the road?
