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.
- 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.
