What is the Load:Recovery ratio for Oxidative pathway?

• A. 1:1
• B. 1:2
• C. 2:1
• D. 3:1

Answer: (A)

The key idea is how to structure intervals to keep the work predominantly coming from the oxidative (aerobic) system. The oxidative pathway powers activity over longer durations and relies on oxygen, so the training design should allow enough recovery to restore aerobic energy production between bouts without letting the effort drop into a predominantly non-oxidative recovery pattern.

A one-to-one ratio means the time spent working is matched by an equal amount of recovery. This balance keeps the body in an aerobic state during the work interval and provides enough time to recover so the next bout again relies on oxidative metabolism. If recovery were much longer, you’d underload the oxidative system and shift toward lower-intensity, non-oxidative steady-state work; if recovery were shorter, the work would lean more toward anaerobic pathways, and the oxidative system wouldn’t be the primary driver during the intervals.

So, the one-to-one ratio best aligns with training the oxidative pathway. For example, matching a 2–3 minute work interval with a 2–3 minute recovery interval maintains aerobic demand and allows repeated aerobic bouts.
