When applying the FITT principle to a season-long training program for an elite 400 metre runner, which of the following describes the MOST appropriate progression of the intensity component over 10 weeks?
- Begin with high-intensity anaerobic training (90-100% max effort), maintain throughout, then reduce intensity (60-70% max effort) in final weeks
- Begin with moderate aerobic endurance (70-80% max HR), immediately progress to maximal sprints (95-100% max effort), then maintain high intensity
- Begin with low-intensity aerobic endurance (60-70% max HR), progress to moderate-intensity (75-85% max HR), then perform high-intensity intervals (90-100% max effort)
- Maintain consistent moderate intensity (75-85% max effort) throughout all weeks, increasing only volume and decreasing volume in final weeks
