Does training in zone 3 increase aerobic efficiency more than zone 2, and if so, what specific physiological adaptations occur in zone 3 that contribute to this increased efficiency?
When comparing the two zones, zone 2 is typically associated with a moderate intensity and is often used for endurance training, while zone 3 is characterized by a higher intensity and is often used for tempo and lactate threshold training.
Are there specific differences in the way the body utilizes fat and carbohydrates for energy in zone 3 versus zone 2, and do these differences contribute to increased aerobic efficiency?
Additionally, are there any specific training protocols or workouts that can be used to target zone 3 and maximize aerobic efficiency gains, and how do these protocols compare to those used for zone 2 training?
Are there any differences in the way zone 3 and zone 2 training affect mitochondrial density, capillarization, and myoglobin levels, and do these differences contribute to increased aerobic efficiency in zone 3?
What role does lactate threshold play in determining aerobic efficiency in zone 3 versus zone 2, and are there any specific training protocols that can be used to target lactate threshold and maximize aerobic efficiency gains?
