It’s a common question: “what is the best exercise?” And more and more research is supporting a single answer. Exercise that supports healthy muscles seems to be the best for improved aging, as well as lowering risk factors for chronic disease.

Muscle health + improved aging rate of the brain

A recent research study from King’s College London looked at how muscle health, measured by power in the legs, is associated with an improved aging rate of the brain.

300 healthy female twins participated in the study

Over 300 healthy female twins participated in the study over a 10 year period. Genetic factors that could affect cognition were controlled. Thinking, memory and learning ability were measured at the beginning and end of study, and it was seen that leg power was a more consistent predictor of cognitive health and ability than any other lifestyle factor tested.

The twin who had more leg power at the initiation of the study generally was seen to sustain this power throughout the study, and had better cognition and fewer brain changes associated with aging over the 10 years.

Other studies have shown that physical activity has a tremendous benefit to the aging process, including cardiovascular and brain health. Muscle training seems to release hormones that actually promote nerve cell growth.

Legs are the largest muscle group in the body

Since the legs are the largest muscle group in the body, it is not surprising to see that there is a specific link between their power/strength and cognitive performance. This does not necessarily mean that the stronger a person’s legs are the better their cognitive ability; there are certainly other factors that come into account, which is why this study specifically looked at female twins – so some factors related to genetics could be accounted for.

Health of the muscles

It is the health of the muscles that is the biggest indicator, and an indicator of health in these big muscle groups is certainly power/strength, but this strength would certainly need to be contextualized – what is considered diminished strength for a 6 ft tall couch potato man, might be completely normal and healthy for a 4’10 teen athlete.
