When applying the FITT principle to a season-long training program for an elite 400m runner, which of the following describes the MOST appropriate progression of the intensity component?
- Begin with moderate-intensity aerobic training (65-75% max HR), progress to high-intensity intervals (85-95% max HR), then maintain low-intensity recovery sessions (50-60% max HR) during competition phase
- Begin with high-intensity anaerobic training (90-100% max effort), progress to moderate aerobic endurance (70-80% max HR), then perform race-specific intensity intervals (85-95% max effort) during competition phase
- Begin with low-intensity aerobic endurance (60-70% max HR), progress to moderate-intensity threshold training (75-85% max HR), then perform high-intensity race-specific intervals (90-100% max effort) during competition phase
- Begin with alternating high (90% max effort) and low (60% max effort) training days, maintain this pattern throughout, then reduce all training intensity (40-50% max effort) during competition phase
