This is a massive bonus for athletes doing mass start events where efforts between 30 seconds- 4 minutes are vital. The introduction to the 4 supra threshold ranges and their prescriptive nature now offers an added level of precision when formatting a training plan. This in part plays a pivotal role when prescribing intervals and tracking your bodies response. Understanding your phenotype and how your body works to produce power is paramount. Importance- Through iLevels, the PD curve, and modeled FTP, WKO4 will phenotype a rider. The significance lies in the software’s ability to interpret micro changes in the PD Curve to provide the most up to date ranges (time and power) specific each individual athlete and their unique physiology. What is unique to this model is the fact that ranges adjust daily and automatically. What are they– According to the WKO4 Product Manager and elite coach Tim Cusick, iLevels are training levels that are configured by blending modeled functional threshold power (mFTP) and modeled power duration data to track with your actual capabilities and ensure that training targets (power and time) are optimized to produce maximal results. See the image below for a side by side comparison of the two models-image from “How to Individualize Training in WKO4 on 5.9.16 Dr. These four zones replace VO2 Max and Anaerobic Capacity in the classic level based model. With that there are 4 individualized zones above FTP which are- FRC/FTP, FRC, Pmax/FRC, and Pmax. Andrew Coggan’s iLevels we now have a 9 level system with precise wattage and time parameters to operate within. With the inception of WKO4 and more importantly Dr. Andrew Coggan’s Classic zones which were based off percentages of a finite value, generally obtained from a 20 minute field test. Up until about year and half ago athletes and coaches were training using Dr. Andrew Coggan’s ilevels in WKO4 provide the most accurate and now individualized framework to track the stimuli-response relationship. Likewise, a sound training plan requires tracking your training with regard to stimuli specific to areas of opportunity, balancing fitness, and maximizing overall time spent training.ĭr.
You have the power meter, head unit, and ability to auto sync your data to Training Peaks, WKO4, Strava and many other online tools using your phone’s Bluetooth capabilities, but are you maximizing these tools and more importantly the information you’re gathering? At its very core training with power is an extremely precise way of quantifying your individual strengths and limiters as those attributes align to the demands of your goals.
