5.11 Clinical significance
Short-term reductions in daily step number (producing less daily physical activity) cause
decreased CRF, loss of insulin sensitivity, reduced lean mass and increased visceral adipose
tissue. These functional decrements help explain the link between reduced physical activity
and the risks that have been associated with the progression of chronic disorders and
premature mortality (389). Using physical activity prescriptions to prevent physical
inactivity would help maintain functional capacities.
