The CTL (Chronic Training Load), ATL (Acute Training Load), and TSB (Training Stress Balance) are key metrics in sports science for monitoring and optimizing athletic performance. These indices help coaches and athletes understand the impact of training on recovery and overall fitness.
The CTL is a long-term average of the training load, calculated using an exponential smoothing factor \(\alpha\). The ATL represents the short-term average and reflects recent training intensity. TSB is the difference between CTL and ATL, indicating whether an athlete is in a positive or negative training balance.
