Strength, Endurance & Cognitive Aging

Mark Richardson - Monday, June 26, 2017

G'day everyone,

This weeks post is of dual purpose.  First up I'm sending you a resent study report from Finland, published in Medicalxpress.
 Now I do not endorse all the side adds & links. I do wish you to focus on the article, itself.
I have been somewhat of a Town Crier in regards to this article. I'm now in my 5th decade of living with JRA & RA {Juvenile Rheumatoid Arthritis, Rheumatoid Arthritis}. If it were not for a passion for movement, I believe I would be lost. All movement does begin in musculature. Whatever age I was, I found the courage to try everything/everyway there was to move my body. Absolutely the stronger I maintained my body the better my over all performance. It has long been proven that the hard the body is worked, the more it can do work. This for sure relates to my cognitive performance. Remember the fact that exercise does relieve stress & allows for less pain. Endorphins are our best friends I think I have held two Gym memberships through all these years. I've relied on resistance training using my own body weight. Then once adapted to the movement & reps. I would find something else to hold onto or push to increase the resistance.
Like forward to sharing again with you soon.
Cheers, be Safe, move Safely/Mindfully

Greater muscle strength – better cognitive function for older people

June 26, 2017

Greater muscle strength is associated with better cognitive function in ageing men and women, according to a new Finnish study. The association of extensively measured upper and lower body muscle strength with cognitive function was observed, but handgrip strength was not associated with cognitive function. Cognition refers to brain functions relating to receiving, storing, processing and using information. The findings were published in European Geriatric Medicine.

The study population comprised 338 men and women with an average age of 66 years. Their  was measured utilising handgrip strength, three lower body exercises such as leg extension, leg flexion and leg press and two upper body exercises such as chest press and seated row. Sum scores to depict lower body and upper body  strength were calculated separately, and cognitive function was assessed using the CERAD neuropsychological test battery with calculated total score.

Handgrip strength is relatively easy and fast to measure, and it has been widely used as a measure of muscle strength in various studies. However, this new study could not demonstrate an association between muscle strength and cognitive function when using a model based on mere handgrip strength and age. Instead, an association between muscle strength and cognitive function was observed only when sum scores depicting upper or lower body muscle strength were included in the model.

"The findings suggest that it may be justified to go beyond the handgrip and to include the upper and lower body when measuring muscle strength, as this may better reflect the association between muscle strength and cognition," says Early Stage Researcher Heikki Pentikäinen, the first author of the article, who is currently preparing a PhD thesis on the topic for the University of Eastern Finland.

Exercise is known to have various health benefits, and  is a way for practically everyone to increase  and enhance muscle strength. However, the association of muscle strength with various aspects of cognitive function is a relatively under-researched area. The study provided new insight into the methodology of measuring muscle strength and into the role of muscle  in cognitive function. The study constituted part of the extensive, population-based DR's EXTRA study, which was a four-year randomised and controlled intervention study analysing the effects of exercise and nutrition on endothelial , atherosclerosis and cognition. The study was carried out at Kuopio Research Institute of Exercise Medicine in 2005–2011 and it involved more than 1,400 men and women living in the eastern part of Finland.
