Understanding Training Stress Score (TSS) in Exercise Physiology

The chapter delves into the concept of Training Stress Score (TSS) in exercise physiology, explaining its calculation based on Functional Threshold Power (FTP) and the relationship between FTP and TSS. While highlighting the significance of TSS in training software, the discussion emphasizes not solely focusing on achieving a high TSS but understanding the quality of the training ride. The chapter also explores the importance of incorporating various metrics, athlete feedback, and personal experience in training planning, rather than solely relying on TSS or Chronic Training Load (CTL) metrics.
