![]() ![]() ![]() It will be used as the default method for swim workouts when there is enough data present to calculate. Accuracy Level: sTSS is in Beta, so we are still working through exactly how accurate it is.Intensity Factor (IF) for rTSS: For any workout or part of a workout, the ratio of the Normalized Graded Pace to the runner's functional threshold running pace, which gives the user a relative intensity in relation to their threshold pace.Normalized Graded Pace (NGP): The adjusted pace reported from a global positioning system (GPS), or other speed/distance device, that reflects the changes in grade and intensity that contribute to the physiological cost of running on varied terrain.Run Training Stress Score (rTSS) Explained Further details on rTSS can be found here: rTSS is a metric that can only be used in running workouts, as the algorithm only accounts for the unique physical demands of running. Coupled with the duration of the workout, we can determine an appropriate rTSS score for each workout. In particular, the elements of the normalized graded pace (NGP, see below), relative to the functional threshold pace. Since running pace is a function of power, and for most runners, speed or pace is the measure of greatest interest, we can use the same principles applied in the TSS system to quantify training stress in running. What is rTSS? Running Training Stress Score (rTSS) is similar to Training Stress Score (TSS), but instead of being powermeter based, it is based on pace. TRIMPS CALCULATOR SERIESRequirements to Calculate: Workout time series with pace and elevation data, user threshold pace for run/walk (entered in pace/speed zones).Accuracy Level: rTSS is the second most accurate method of calculating a Training Stress Score, and is the default method for Run workouts when there is enough data present to calculate.Applicable Workout Types: Run only (TSS can not be calculated for bike workouts from speed).Normalized Power, Intensity, Factor, and Training Stress Score Intensity Factor (IF) for TSS: For any workout or part of a workout, the ratio of the Normalized Power to the rider's functional threshold power, which gives the user a relative intensity in relation to their threshold power.Normalized Power (NP): An estimate of the power that you could have maintained for the same physiological "cost" if your power had been perfectly constant, such as on an ergometer, instead of variable power output. By definition, one hour spent at Functional Threshold Power (FTP) is equal to 100 points. It is conceptually modeled after the heart rate-based training impulse (TRIMP). What is TSS? Training Stress Score (TSS) is a composite number that takes into account the duration and intensity of a workout to arrive at a single estimate of the overall training load and physiological stress created by that training session.Requirements to Calculate: Powermeter data file containing time series duration and power data, power threshold (FTP) set in Power Zones section of My Settings.Accuracy Level: power-based TSS (compared to hrTSS, tTSS, or TSS*) is the most accurate method of calculating a Training Stress Score, and is the default method for Bike workouts when there is enough data present to calculate.Applicable Workout Types: Bike or Rowing with Power Meter only.Below are each of the training scores, how they are calculated, and the level of accuracy for each metric. TrainingPeaks uses several physiological metrics to quantify the training stress of a particular workout or portion of a workout. ![]()
