That is correct. 60min TT will give you your Functional Threshold Power (FTP) which correlates well with power at Lactate Threshold. The other durations tell you how much power your other energy systems in your body produce: 5min power correlates with pVO2Max 1min power indicates anaerobic capacity 5sec power indicates neuro-muscular power These are the real world numbers on the bike - not something done in a lab etc. This provides you with your true capabilities on a bike, and provides information as to what your strengths and weaknesses are, what your potential as a cyclist is, and what type of events will suit you best. All you need to do is ride these durations as hard as possible. No rocket science, just real world information. You may need to practice them a few times to learn how to pace the efforts, particularly 5min and 20min.
