Revealing Hidden Secrets of Youthfulness
One recent study published by the journal of the Canadian Public Library of Science, PLoS One, found that energy-producing skeletal muscle cells called mitochondria can be revitalized with weight training exercises.
In the Canadian study, seniors averaging 70 years who were active and healthy were led in exercise programs twice a week for one hour of general exercises involving weight lifting for a period of six months. Biopsies of their thigh muscles were taken both before, and after, the program.
When the weight training is done by seniors, the study further reported that this mitochondrial matter could be returned to a condition similar to that found in much younger people.
"There's accumulating evidence to show that mitochondria are involved in the aging process and if the mitochondria don't work very well, the energy, the endurance and the strength of muscles become diminished," study co-author Dr. Mark Tarnopolsky of McMaster University, who was located in Hamilton, Canada.
As an indication of how important muscle mass is, the latest analysis by the Center for Disease Control and Prevention shows that more than 13,700 seniors in America died from falls in 2003 alone. “Falls are the leading cause of injury death among the elderly,” stated Michigan University balance researcher Neil Alexander.
In fact, researchers disclosed to the American Geriatrics Society during its 2007 meeting held in Seattle, Washington that older women are at greater risk of death after suffering a hip fracture than after contracting breast cancer. Dr. Jane A. Cauley, DrPH, who is a professor of epidemiology at the University of Pittsburgh in Pennsylvania, stated ‘[Our] study should raise the general level of awareness of the impact of hip fracture on the lives of elderly women.” She added, “There is already a greater general level of awareness of the public health impact of breast cancer; but, in fact, our study showed that the mortality of breast cancer in this population was less that that of hip fracture. The public health impact on mortality was much greater for hip fracture that for breast cancer, even after adjustment [for statistical factors].”
Dr. S. K. Bulstra, MD, a professor of orthopedic surgery at the University Medical Center of Groningen in the Netherlands, making an independent analysis of the study by Dr. Cauley, stated "The implications of this study are that we should aim more studies at the correct treatment of the patient with a hip fracture.”
Dr. Bulstra, as could be expected of an allopathic medical doctor, completely missed the issue presented by Dr. Cauley’s study: how do we prevent hip fractures in the elderly, both in women and in men? Better treatment after the fracture is certainly not where emphasis should be stressed if the age-old adage of “an ounce of prevention is worth a pound of cure” yet retains its currency.
Co-Author Dr. Mark Tarnopolsky stated of the Canadian study, "The main, novel finding [of our study is] that we could bring that aging mitochondria pattern back towards a younger person, almost reversing the aging signature, pretty much by 40, 45 years with six months of weight training." He added "What's cool about that is that this aging is reversible – maybe not 100 per cent – but at least at the cellular level, we're seeing a significant reversal of accumulated damage over a long period of time."
Scot E. Long, MSS, CSCS, who is an exercise physiologist and a doctoral candidate at the University of Southern Mississippi in addition to being an adjunct professor at Mississippi College, stated, “Long bouts of cardio - especially without strength training - can cost valuable muscle tissue and damage joints, and the cardio-respiratory benefits simply don't require the long times and distances many people put in today. As a matter of fact, most runners who don't regularly strength train have very low levels of strength, power, balance, coordination and agility. These are all necessary aspects of the skill-related components of fitness that many once thought only athletes needed. We all need these components for our jobs, hobbies, sports and the physical requirements of life itself such as yard work, changing a tire and staying optimally healthy.”
Physiologist Long further stated, “Strength-training machines are also still popular with the idea that older people, the injured and inexperienced must use machines to be safe. Not true. Free weights using both power lifting and Olympic weight lifting techniques can be used for everyone. Whether you are elderly, very young, injured, a school teacher or a SWAT team member, the benefits are waiting for us all.”
But, breaking out in a sweat like Arnold used to do is not the only answer, although its benefits may be much more quickly realized than non-impact exercises such as tai chi. But, these low-intensity exercises can reap bountiful rewards.
In fact, Steven Wolf of Emory University says, “… it takes three months of tai chi for someone who is really frail to regain strength and flexibility.” He added, “In Western medicine, we expect instant results. But, that’s not what happens here.”
In a an apparently unrelated Swedish study from the Karolinska Institutet in Stockholm, Sweden, researcher Anna-Greta Mamhidir stated, “Weight loss is a common issue among people with dementia and in particular Alzheimer’s.”
In the Swedish study, two groups comprised of seniors suffering from varying, yet similar, degrees of dementia and Alzheimer’s were compared. The so-called “invention” group was simply provided more physical stimulus including movement. The “control” group was left alone.
"Patients [in the intervention group] took part in activities, sat at the table together during mealtimes and served themselves food from bowls, encouraging them to be more independent and interact more with other patients" stated Ms. Mamhidir.
The results were that the intervention group markedly increased weight, by as much as 15 pounds in one case, during the term of the 3-month study.
The study was undertaken to determine if the increased activity and interaction by the seniors in the intervention group could be correlated with weight gain by it. The motivation for determining weight gain, in turn, is that weight loss is a significant aspect in the syndrome of dementia and Alzheimer’s. Thus, it was concluded by the Swedish researchers that if activity could induce more eating, the possibility existed that the onset or impact of dementia and Alzheimer’s might be reduced. As to be expected of the allopathic approach, the leaders of the Swedish study missed the point completely. Roger Watson, who is the editor of the Journal of Clinical Nursing, stated that the Swedish research made a significant contribution to the field of food and dementia. “The [Swedish] study shows a marked difference in weight change between the intervention and control groups and a strong link between weight gain and improved intellectual ability,” he stated.
Again, the actual point of the Swedish study is missed by those analyzing it. The point is simply this: we are all animals and like animals in the wild if we don’t keep hunting we die, whether that hunting is experiencing the strain of a new tai chi position or, as in the Swedish study, simply making an elderly person fill their own soup bowl instead of catering it to them.
