Often we discover our capabilities and strengths when we place our self in situations that require action as opposed to reaction.
Taking proactive action is creative and enriching; it brings with it a true sense of curiosity and zest for life.
Consistent exercise enables the body and mind to enjoy and be grateful for the many wonders and experiences that life continues to offer.
Let’s not forget.

An Australian study (Study of Mental and Resistance Training (SMART )) published this week in the Journal of American Geriatrics has made worldwide headlines.
After heart disease, Dementia and Alzheimer’s is the leading cause of death, and it is projected to reach 135 million worldwide by 2050.
Findings from the study were unique in showing for the first time, a positive causal link between resistance training and the functioning of the brain for people over 55, with mild cognitive impairment.
It is important to note that the study looked at different exercise; including light resistance training. However, it was the group that trained at 80% peak strength (level 8) that showed the greatest improvement in both muscle mass and cognitive ability.
The study measured the hippocampus and found that it had increased in size with the intense exercising.
The hippocampus is a “seahorse” shaped part of the brain, just behind the ear, it is responsible for the processing of memory and emotional responses. It is the first area of the brain to deteriorate with the onset of Alzheimer’s disease.
Alzheimer’s Disease can begin as young as 35
Alzheimer’s disease can be either sporadic or familial. Sporadic Alzheimer’s disease is the most common, and the likelihood of developing the disease doubles every five years after 65 years of age.
Familial Alzheimer’s disease is a very rare genetic condition, with symptoms beginning as young as 35.
The SMART study is encouraging because it shows that it is never too late to start weight training for positive mental health.
Exciting research into Alzheimer’s by Prof Cassandra Szoeke is based on the Melbourne Women’s Midlife Health Project.
The Melbourne University project is the most comprehensive of its kind, and is following more than 400 Australian-born Melbourne women from 1991, then aged between 45 and 55.
Prof Cassandra Szoeke’s, study focuses on looking at preventative strategies for the onset of Alzheimer’s. The study is revealing trends that the degeneration of the memory function is beginning as early as 20 – 30 years before the first symptoms of Alzheimer’s Disease.
What is interesting about her study is that among the women who are exercising daily, the tests measuring memory recollection, are not showing any memory deterioration over the now 25-year study.
Brains and Brawn
.
Weight training has traditionally been thought to be in the realm of the simpleton. The idiom “all brawn and no brain” adds to the misconception.
The idiom may have originated in China between 1644-1912 and was used as propaganda to separate the working class people “brawn” from the government workers “brains.”
Unfortunately, in our society there is a tendency to consider manual workers as less “intelligent” than a university professor and manual labourers tends to have lower social prestige.
While there is not conclusive research on muscle gain and the prevention of Alzheimer ’s disease, the SMART study results are helping start the conversation about the scientifically proven importance of resistance training.
Further, it is elevating the perception and therefore the engagement in weight training among academics, professional, and sedentary people, where muscle deterioration and Dementia seem to coexist.
