Lessons from Masters World
Records: Lack of Gender Differences In Aging Muscle Decay Rates by Albertin G* in
Research & Investigations in Sports Medicine_ Journal of Sports Medicine
Abstract
The
physiology and physiopathology of muscle aging differ between female sand
males. Here, our aim is to investigate gender differences in the rate of the
age-related decay of skeletal muscle performance using a complete series of
female and male normalized master’s world records. Masters athletes compete in
age groups of five-year divisions and range from 35 to 100 years of age. The
world records are lists of up to 16 data points that, after normalization, can
be interpolated with polynomial
trend-lines with a high R2. Gender comparisons were performed for 19 Track
and Field specialties using weighted regression analyses. As expected, the
aging decline began at 35 years for both the women and men. Despite differences
in the 19 Track and Field Masters world records for female and male athletes in
the same age groups, in comparing the normalized female and male Masters
athlete world records, the rates of aging performance decay were very similar
if not identical. This lack of gender difference is a unique exception to the
general rule of gender differences in sports activities, suggesting that neuro-hormonal mechanisms poorly
influence the rate of aging muscle power decay. We then discuss the hypothesis
that age-induced decline is related to fundamental cellular mechanisms, perhaps
those that control energy
metabolism. The limitations and implications of our hypothesis are
discussed as well.
