Form (TSB)

TrainingPeaks represents TSB (Form) in yellow font and the yellow line (in the Performance Management Chart) through the TrainingPeaks ecosystem.

What is TSB (Form)

Training Stress Balance (Form) represents the difference in the balance of training stress. TSB provides a measure of how much an athlete trained recently (ATL), compared with how much an athlete trained historically (ATL). TrainingPeaks calculates TSB by subtracting yesterday's Fatigue from yesterday's Fitness. Form (TSB) = Yesterday's Fitness (CTL) - Yesterday's Fatigue (ATL). TSB is not as a predictor of performance but as a measure of how adapted an athlete is to their training load. 

Formula

Form (TSB) = Yesterday's Fitness (CTL) - Yesterday's Fatigue (ATL)

Note:

  • The TSB value for today represents tomorrow's value, not today's, because athletes want to know how fresh they'll be before tomorrow's workout or race. 
  • A positive TSB number means that you are 'Fresh', or over adapted to your current training load.  
  • A neutral or nearly neutral TSB number means that you are adapted to your current training load. 
  • A negative TSB number means you are not adapted to a training load.
