It takes work to stay in shape which is part of why working out on the regular is so important. But sometimes, for whatever reason, you miss a workout. And sometimes missing that workout can lead to missing several workouts.... To properly understand what happens when we stop working out, we should first take a look at what happens when we DO exercise. Exercises that are on the endurance end of the scale -- like running or rowing -- all have a profound impact on measures of fitness such as oxygen uptake in the body. Andreas Bergdahl, an assistant professor in cardiovascular physiology at Montreal’s Concordia University, says that regular exercise has 4 major consequences in the body:
- Increased ability of the heart to eject blood
- Increased ability of the blood vessels to send blood to where blood is needed
- Increased number of capillaries (the vessels that deliver oxygen and ‘food’ to the muscles)
- increased size and the number of mitochondria (the “power plants” of the cells).
