The muscles of older women and men who have been exercising regularly for decades have proven to be inseparable in many ways from those of much younger healthy people in an active seventy-year-old study group. published in the Journal of Applied Physiology.
Older active participants also had aerobic abilities well above those of most people in their age group. The results of the study showed that they were biologically younger by 30 years younger than their chronological age, according to the researchers.
Every second of every day, the body gets older, which makes it much more difficult to question what to expect when the body ages in subsequent years and decades. Statistics and observations suggest that older people suffer from illness, frailty and dependency, but science has not established whether and to what extent such physical decline is inevitable with age or if it is partially a by-product of the modern way of life and perhaps subject to change. .
Many studies suggest that physical activity can alter our aging. Older athletes have recently been found to have healthier brains, immune systems, hearts, and muscles than sedentary people of the same age; but many of these studies focused on competitive athletes and not on those who play sports and few women were included.
Ball State University examined a distinctive group of older men and women who began exercising during the boom years of the 1970s and who either maintained this hobby for the next 50 years years, or have never competed since. 28 participants were recruited including 7 physically active women. Older, age-matched people who had not exercised during their childhood, and a group of people in their twenties were also recruited.
All subjects were laboratory tested for their aerobic capabilities and the number of capillaries and the levels of certain enzymes in the muscle were measured using tissue samples; high numbers for everyone indicate muscle health.
The cardiovascular system and muscles have been targeted because they are thought to decrease with age. A hierarchical trend in the differences between the groups had to be observed. The youngest subjects were expected to have the strongest muscles and aerobic abilities, with life-time exercises being slightly lower in both cases, and older non-practitioners becoming more deflated. However, these results are not what they found.
The muscles of older athletes were found to resemble those of younger subjects with many similar capillaries and enzymes and far more than those of sedentary elderly subjects. Active older adults had lower aerobic abilities than younger subjects, but their abilities were 40% higher than those of their sedentary peers.
When the aerobic capacities of the active older subjects were compared to those of the "normal" abilities established at different ages, the researchers calculated that the older active group had the cardiovascular health of those 30 years younger than themselves. -Same.
The combined results on cardiovascular and muscular health in active older adults suggest that physical deterioration considered normal as related to age may not be normal or inevitable; and that exercise can help build up a reserve of good health from an early age, which can help us slow down or avoid physical frailty at a later age.
As this cross-sectional study only highlighted one moment in the subject's life, she can not say whether physical exercise habits directly caused differences in health or diet-related factors. , diet or lifestyle contributed. In addition, muscle mass and other important health measures have not been examined, or you can start exercising late in life and enjoy the same benefits; However, the team plans to consider some of these issues in future studies.
