Walking in short bursts found to consume 20% to 60% more energy than walking continuously for same distance (phys.org)

Super interesting and makes a lot of sense in retrospect.

But without the high intensity part. Just starting and stopping something as simple as a walk can increase energy consumption by over 50%, I found that neat. The comparison to a car really resonated with me; I hate coming to a stop because I know it kills my gas mileage, but now I want to try to emulate that in my daily physical activities

I saw an interview with some exercise scientists talking about studies done on people who lived in rural less developed environments, think shepherds in developing countries. The studies indicated that while they may do 30,000 steps a day their body physiologically adapts and changes their movement paterns very quickly to use the absolute minimum amount of energy possible to move around. So their energy expenditure was more like what someone who walks 15,000 steps a day of stop start a day.

So, this is what cyclists do. Lots and lots of low intensity miles, to facilitate those adaptations, so that over time they put out the same power but at a much lower energy cost.

Conversely, those seeking to maintain high cardiovascular fitness must cross-train with a variety of exercises, to maintain the load on the heart a lungs .
