Longer Telomeres via Long-Term Endurance Exercise

Posted Jan 04 2013 10:11pm

Telomeres are the end caps of chromosomes, protecting the DNA complexes from deterioration during cell division. Telomere shortening is considered a marker of cellular aging, and prematurely shortened telomeres have been linked to increased risk of cancers, heart disease, dementia and death.  Researchers from the Norwegian University of Science and Technology (Norway) report that endurance training may protect against the effects of aging in older individuals.  Javaid Nauman and colleagues recruited 20 men, half of whom were ages 22 to 27 and the other half ages 66 to 77. In each age group, half of the participants were endurance athletes who were taking part in a cross-country ski race or track competitions. The others were nonathletes who were active, but who had never competed at higher levels in any sports. All of the participants were free from known cardiovascular disease, obesity, and a history of current or past smoking. None was taking regular medications.  The team observed that in the older age group, the endurance athletes had significantly longer telomeres.  Further, in the overall cohort, telomere length was positively associated with VO2max, with the relationship strongest among the endurance athletes.  The study authors write that: “Our data suggest that VO2max is positively associated with telomere length, and we found that long-term endurance exercise training may provide a protective effect on muscle telomere length in older people.”

World Congress on Anti-Aging Medicine & Regenerative Biomedical Technologies Showcases Innovations in Clinical Aging Intervention:
Older athletes who engage in endurance training have longer telomere length, and maximal oxygen consumption positively associates with telomere length.
The rate of people who seek preventive cancer screenings has fallen over the last ten years in the United States.
Intensive lifestyle-based weight-loss interventions associate with a partial remission of diabetes.
High perceived stress associates with a moderately increased risk of incident coronary heart disease
Meals at which the entire family dines together encourage children to consume fruits and vegetables.
On-off switch for microRNAs – tiny strands that regulate gene expression – contribute to the heart's ability to regenerate.
Higher dietary intake of pyridoxine (Vitamin B6) associates with reduced risk of hip fracture, among women.
People may lose 30 minutes of life expectancy for every two cigarettes, for being 11 pounds overweight, and for eating an extra portion of red meat daily.
Supplementation with omega-3 fatty acids may postpone the onset of metabolic disorders and associated declines in cognitive functions.
Seniors who engage in regular physical activity are less likely to experience loss of brain volume and potentially retain cognitive skills.
People who lift weights are less likely to have metabolic syndromea cluster of risk factors linked to heart disease and diabetes.

T cells become more responsive in exercising cancer survivors weeks after chemotherapy ends.
Soccer (football outside the US) helps men with high blood pressure to improve their fitness, normalize their blood pressure. and reduce their risk of stroke.
A regular exercise program that focuses on intensity of activity, rather than duration, may significantly reduce the risk of markers implicated in diabetes
As little as 6 months of exercise can improve memory, language, thinking and judgment problems by almost 50%, in people affected by stroke.
Daily physical activity can boost a person's mental health, via the psychological mechanisms known as the self-image hypothesis and the social interaction hypot
The very elderly and frail can enjoy the benefits of exercise in terms of their physical and cognitive faculties and quality of life after only three months.
Middle-aged adults who regularly engage in leisure-time physical activity for more than a decade may enhance their heart health.

#101 - Flush with Food
Thanks to today’s contemporary lifestyle of fast foods, our 24/7/365 accessibility, and the growing pressures of many of us in our professional and personal lives, we have become a population of toxemics. “Toxemia” is the medical term that defines a condition in which our bodies accumulate poisonous substances to such a point that levels exceed the ability of our body systems to cleanse them away. Medical conditions associated with toxemia include:

• Hepatitis A, B, C, D, E, F, and G

• Liver damage, including cirrhosis

• Diarrhea

• Constipation

• Irritable bowel syndrome

• Leaky gut syndrome

Include fiber in your everyday diet, because fiber can promote the digestive and elimination processes to help your body get rid of toxins (see Tip 42).
