Webinar Overview: Individualizing Your Training with WKO
TrainingPeaks WKO Product Leader Tim Cusick hosted this webinar walking through the why and how of individualizing your training to improve performance and results.
Power Duration Metrics Two Minute Tutorials
Don't have time to watch the full webinar? Check out these quick tutorials explaining the metrics based on WKO's power duration model.
Power Duration Model (PDM)
The power duration model is an estimate of the relationship between time to exhaustion and work rate during both anaerobic and aerobic exercise; units are W or W/kg.
Phenotype
Phenotyping is the objective (i.e., statistically-based) classification of an athlete into one of four phenotypes.
Pmax
Pmax is the maximal power that can be generated for a very short period of time, the maximum power over at least a full pedal revolution with both legs. Units are W or W/kg.
Functional Reserve Capacity (FRC)
FRC is the total amount of work that can be done during continuous exercise above FTP before fatigue occurs. Units are kJ or J/kg.
Modeled VO2max Defined
mVO2max is the maximum amount of oxygen the body can use during a specified period of usually intense exercise.
Modeled Functional Threshold Power (mFTP) Defined
mFTP is the model-derived highest power a rider can maintain in a quasi-steady state without fatiguing.
Time to Exhaustion (TTE) Defined
TTE is the maximum duration for which a power equal to FTP can be maintained.
Stamina Defined
Stamina is a measure of resistance to fatigue during prolonged-duration, moderate-intensity (i.e., sub-FTP) exercise. Units are percent of maximum, i.e., 0-100%, although most individuals will fall in the 70-90% range.
The Science Behind the Power Duration Model in WKO
