What are the potential drawbacks of using TrainerRoads ramp test as the sole method for determining Functional Threshold Power (FTP), and are there any alternative methods that could provide a more comprehensive picture of a riders fitness level? Specifically, are there any concerns that the ramp test may not accurately capture the nuances of a riders power profile, such as anaerobic capacity or sprinting ability, and if so, how can these limitations be mitigated?
Additionally, what are the implications of relying solely on the ramp test for FTP determination, particularly for riders who have a high anaerobic capacity or those who are training for events that require a high level of sprinting or explosive power? Are there any scenarios in which the ramp test may overestimate or underestimate a riders true FTP, and if so, how can these discrepancies be accounted for?
