Stopping Exercise Decreases Brain Blood Flow

Master athletes who stopped exercising for only 10 days showed a decrease in blood flow to brain regions that are important for maintaining cognitive health.

We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research led by University of Maryland School of Public Health researchers examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain regions, after they stopped their exercise routines.

Therefore, do not stop your routine.  You can vary the duration and intensity of each workout.  You can even take a day off.  Barring illness, not more than 3 consecutive days should be well within the studied 10 days.  This will keep your body and brain physically fit.
