Anaerobic Capacity
What is Anaerobic Capacity?
Anaerobic capacity refers to the total work your body can perform using energy systems that do not require oxygen — primarily the phosphocreatine system (first 10-15 seconds) and anaerobic glycolysis (up to 60-90 seconds). In rowing, anaerobic capacity determines: sprint performance (100-500m), the starting burst in a 2K race, and the finishing sprint. The 2K test is approximately 20-25% anaerobic. Anaerobic capacity is developed through short, maximal intervals: 10 x 100m with full rest, 8 x 250m with 3:00 rest, and sprint starts. It is trainable but has a lower ceiling than aerobic capacity — most improvement in 2K times comes from aerobic development rather than anaerobic gains.
How Watta Uses Anaerobic Capacity
Watta captures the high peak watts generated during anaerobic efforts. The Work Output component of the Effort Score reflects the power produced during sprint sessions, while the Cardiac Load tracks the cardiovascular response to anaerobic work.
