A typical study upon which this rule of thumb is based is ref. 1 . This is one of the reasons for the maxim “use it or lose it”. It appears to be “really use it so you lose it more slowly”. But it’s important because the difference between 5% and 10% is huge for quality of life. Activities of daily living like being able to go up stairs become very difficult or impossible if VO2Max goes below about 20. This can happen by the time you are about 70 or 80 if sedentary, but can be delayed until more than 100 years of age if you keep training. Another important factor is that it has been shown that aerobic capacity can be regained significantl...
