The Brain & Leg Muscles in Older People
Fitter Legs Mean A 'Fitter' Brain: Leg Strength Could Also Indicate Your Cognitive

Fitter Legs Mean A 'Fitter' Brain: Leg Strength Could Also Indicate Your Cognitive Health.
They found that leg power was a better predictor of cognitive change than any other lifestyle factor they looked at.
Kicking Back Cognitive Ageing: Leg Power Predicts Cognitive Ageing after Ten Years in Older Female Twins
A striking protective relationship was found between muscle fitness (leg power) and both 10-year cognitive change (fully adjusted. Conclusion: Leg power predicts both cognitive ageing and global brain structure)
Muscular power, especially in the legs — which are the largest muscles in the body — is widely accepted as a marker of healthy aging. Older people with relatively powerful leg muscles get around better than those with weak legs. They also tend to have sharper minds, studies show.

“…..new study, which was published last week in the Journal of Applied Physiology, researchers from McGill University in Canada and other schools contacted 29 world-class track and field athletes in their 80s and invited them to the university's performance lab. …..Muscles consist of fibers, each attached to a motor neuron in our spinal column by long, skinny nerve threads called axons. The fiber and its neuron are known as a muscle unit. When this muscle unit is intact, the neuron sends commands to the muscle fiber to contract. The muscle fiber responds, and your leg, eyelid, pinky finger or other body part moves…..Using mathematical formulas involving muscle size and electrical activity, the scientists then determined precisely how many muscle units were alive and functioning in each volunteer's leg muscle. They also examined the electrical signal plots to see how effectively each motor neuron was communicating with its attached muscle fiber…..More interesting to the researchers, the athletes also had almost 30 percent more motor units in their leg muscle tissue, and these units were functioning better than those of people in the sedentary group”
