Muscles of older women and men who have been exercising regularly for decades turned out to be inseparable in many ways from the healthy, much younger people in a study group of active septuagents published in the Journal of Applied Physiology.
The active elderly participants also had much higher aerobic capacity than most in their own age group, the studies showed that they were biological approximately 30 years younger than their chronological ages, according to the researchers.
Every second every day the body’s ages, which makes many deeply interested in what can be expected when the body ages in the following years and decades to follow. Statistics and observations indicate that elderly people experience illness, weakness and addiction, but it has not been established by science whether and to what extent such physical decline is inevitable with age or if it is partly a byproduct of modern lifestyle and may change.
Many studies have suggested that physical activity can change how we age. Older athletes have recently been shown to have healthier brains, immune systems, hearts and muscles than sedentary people of the same age. but many of these studies have focused on competing athletes, not those who practice recreationally and have taken with women.
Ball State University looked at a distinctive set of older men and women who started training under the bars of people practicing exercise as a hobby in the 1
970s that either retained the hobby for the next 50 years, or never competed ever since. 28 participants were recruited, including 7 physically active women. Age matched the elderly who had not exercised childhood, and a group of people in the 20’s were also recruited.
All subjects were tested in the laboratory for aerobic capacity, and the number of capillaries and levels of certain enzymes in the muscle was measured using tissue samples; High numbers for each indicate muscular health.
Cardiovascular systems and muscles were targeted because they are believed to decrease with age. A hierarchical pattern in the differences between the groups was expected to be seen. Younger subjects were expected to have the most robust muscles and aerobic capacity, with lifelong exercises somewhat weaker in both cases and older non-coaches showed worse. But these results were not what they found.
Muscles of older practitioners appeared to resemble the younger subjects with many capillaries and enzymes similar and much more than in muscles of sedentary seniors. Active elderly people had lower aerobic capacity than the younger subjects, but their capacity was 40% higher than their sedentary companions.
When the active elderly subjects aerobic capacity were compared to those with established “normal” capacities at different ages, the researchers were estimated that the older active group had cardiovascular health at the age of 30 years younger than themselves.
Conclusions on cardiovascular and muscular health in active elderly people suggest that what is considered normal age-related physical deterioration can not be normal or inevitable. and that exercise can help build a reserve of good health in younger ages, which may enable us to slow or avoid physical weakness in older ages.
Since this study was a cross section that only highlighted a single moment in the subject’s life, it can not be said whether exercise habits directly caused differences in health if genes, diets or other lifestyle factors contributed. In addition, muscle mass and other important health measures were not seen, or if you can start exercising late in life and have the same benefits. However, the team plans to investigate some of these problems in future studies.
