Glossary: Training Stress Balance (TSB)

Training stress balance is the difference between CTL and ATL (in absolute values) and can help as indicator for hard training (negative values) and rest (positive values). If an important race is ahead, TSB should be clearly positive. As levels of CTL and ATL differ from athlete to athlete, no concrete suggestions can be made.
