Middle Age Weight & RunnersEvery 10 mile per week increment in weekly
mileage was associated with a significant apparent reduction in the waist
line. The average rate of weight gain was the same in men running less
than ten miles per week and those exceeding forty, about 3.3 pounds and
about 3/4 inches around the waist per decade in a 6' man. This may not
seem like much, but the percentage of moderately overweight runners increased
from 21 percent before age thirty to 30 percent between ages 45 to 49.
Statistically, it appears that age-related weight gain and exercise-induced
weight loss are independent, additive effects. Our findings suggest that men who maintain constant weekly distances through middle age are expected to increase total weight and waist circumference (presumably intra-abdominal fat). Running distance needs to increase annually, by 1.4 miles per week in order to compensate for the expected increase in waist circumference between ages 20 and 50. This means that runners who average 10 miles per week at age thirty should increase their weekly running distance to 24 miles by age forty if they plan to still fit into the tuxedo they bought ten years earlier.
