An athlete needs to improve their ATP-PCr energy system to enhance their 100 metre sprint performance. Which application of the FITT principle would be MOST effective?

High intensity at 90-100% maximum effort, 2-3 times per week, with 10-15 second work intervals
Moderate intensity at 70-80% maximum effort, 4-5 times per week, with 2-3 minute work intervals
High intensity at 90-100% maximum effort, 2-3 times per week, with 3-10 second work intervals
Moderate intensity at 70-80% maximum effort, 2-3 times per week, with 20-30 second work intervals

C is correct: ATP-PCr system requires maximal 3-10 second efforts with adequate recovery.

Other Options:

A is incorrect: 10-15 seconds exceeds ATP-PCr capacity; shifts to glycolytic.
B is incorrect: Moderate intensity and 2-3 minutes target aerobic systems.
D is incorrect: Moderate intensity inappropriate for ATP-PCr development.
