What are the most effective interval training protocols for targeting the different cycling energy systems, specifically the aerobic, anaerobic, and high-intensity anaerobic systems, and how can these be tailored to suit different rider profiles and goals, such as endurance, sprinting, or climbing?
Are there specific interval structures, such as high-cadence sprints, hill repeats, or tempo rides, that are better suited to developing each energy system, and how can these be combined to create a well-rounded training program?
What role do factors such as interval duration, rest periods, and overall training volume play in determining the effectiveness of interval training for targeting different energy systems, and how can riders adjust these variables to optimize their training?
