Maximum sustainable power. Functional Threshold Power, or FTP, is one of the key training terms in cycling and is effectively the maximum power you can sustain for an hour. As a result, FTP is seen as a crucial figure in determining your all-round ability on the bike, and is a number top riders swear by.
The threshold potential is the critical level to which the membrane potential must be depolarized in order to initiate an action potential.Threshold potentials are necessary in order to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS).hreshold tracking allows for the strength of a test stimulus to be adjusted by a computer in order to activate a defined fraction of the maximal nerve or muscle potential.
