When it comes to muscle and longevity, quality is more important than quantity. In other words, it’s not muscle size that counts, but muscle strength and the efficacy of the nervous system!… There is a reason why the oldtime physical culture magazines were called “STRENGTH & HEALTH”, and not Muscle & Health! Think about that, folks!
At 75, Would Popeye Still Be Able to Take On Bluto?
(Science Daily) If Popeye were to age naturally like the rest of us, he would need more than just big muscles to stay independent during his senior years. When it comes to muscles and aging, the important thing is quality, not quantity, as shown by the findings of a study by Mylène Aubertin-Leheudre, PhD, a researcher at the Research Centre of the Institut universitaire de gériatrie de Montréal, affiliated with Université de Montréal.
Published in the Journal of the American Medical Directors Association, the study looked at the relationship between functional independence and muscle mass and quality in 1219 healthy women aged 75 and older. It should be noted that these results are applicable to men’s health as well.
The analysis showed that women who maintained better muscle quality (the ratio of strength to muscle mass) also had better functional reserves, which help people maintain independence. Women with lower muscle quality had a three to six times higher risk of developing functional impairments (e.g., difficulty walking, getting up from a chair, or climbing stairs).
“These results contradict what has been believed for a long time about muscles and aging. Many seniors, whom we often perceive as frail and fragile, can surprise us by their muscle strength. Although inevitable, age-related muscle loss (a normal process called “sarcopenia”) should no longer be seen as a sign of weakness,” stated Mylène Aubertin-Leheudre, PhD.
She hopes that these findings will give health care professionals tools to better identify seniors at risk of functional decline and to design physical activity programs that would specifically target resistance and power and not simply a gain in muscle mass. Popeye should take heed!
