Supplements and Weights for Older People




I know that I always preach that exercise, diet, and simple vitamin supplements can help people stay healthy and now I see that yet another study shows that older people can get healthier by taking some carbs and protein before getting exercise, this is also a good idea for anyone getting in shape.

Also the type of exercise that older people do is critically important.

Improving health in older people

A carefully framed combination of moderate exercise and nutritional supplements could help older people maintain an active lifestyle for longer.

A Manchester Metropolitan University study has found that taking carbohydrate and protein supplements just before and just after low-resistance exercise could boost muscle performance and slow muscle wastage in people over retirement age.

Moreover, this combination appears to deliver greater fitness benefits than undertaking heavy-resistance training with or without changing one’s nutritional habits.

Supplements and Weights for Older PeopleThis was the first-ever study of the combination of structured exercise and nutritional supplements to focus wholly on older people. Undertaken as part of the SPARC (Strategic Promotion of Ageing Research Capacity) initiative, the findings will be discussed at this year’s BA Festival of Science in Liverpool on Thursday 11th September. SPARC is supported by the Engineering and Physical Sciences Research Council (EPSRC) and the Biotechnology and Biological Sciences Research Council (BBSRC).

This groundbreaking study involved a carefully selected sample of around 60 healthy, independent-living adults aged 65 and over.

The volunteers were randomly divided into groups who underwent different 12 week programmes of physical exercise and nutritional supplementation. Everyone was then re-assessed at the end of the programme.

Some groups undertook low-resistance exercise once a week; others undertook high-resistance exercise twice a week. Within each group, some of the volunteers took protein and carbohydrate supplements while others did not.

When all the participants were re-assessed at the end of the 12 week programme, it was observed that muscle size and strength had increased in all groups.However, the results suggested that older people would derive the most benefits if they took appropriate supplements coupled with low-intensity exercise.

“Maintaining muscle performance and arresting muscle wastage can offer older people real improvements in their quality of life,” says Dr Gladys Pearson, who led the research. “Though we still need to assess precisely what level of exercise gives the best results, we believe we’ve shown that regular low-resistance exercise complemented by the right nutritional supplements could boost the well-being of the UK’s ageing population.”

Dr Pearson and her team now aim to look at the effectiveness of novel combinations of strength training and nutritional supplementation as a way of speeding recovery and improving mobility for old and young orthopaedic surgery patients.

Aerobic Fitness declines with age

Ran into this interesting article from Reuters:

Jul 26 (Reuters Health) – Physical fitness is known to wane with age, but a study published Monday shows that the decline gains speed with each decade, regardless of a person’s exercise habits.
The study of 810 healthy adults found that the rate of decline in aerobic fitness was about four times greater among people in their 70s or older, compared with those in their 20s and 30s.

Despite the fact that it boosts aerobic fitness, regular exercise did not change a person’s rate of age-related decline.

However, that does not mean it’s time to retire those running shoes, according to the study authors.

At any given age, people who were at least moderately active were more fit than their sedentary peers, said lead author Dr. Jerome L. Fleg of the National Heart, Lung, and Blood Institute in Bethesda, Maryland.

In addition, he told Reuters Health, research shows that older people can improve their aerobic capacity by getting regular, moderate exercise like walking. The point, according to Fleg, is to help elderly people stay fit enough to perform daily activities — like housework or yard work — and maintain their independence as long as possible.

Fleg and his colleagues at the National Institutes of Health report their findings in Circulation, a medical journal published by the American Heart Association.

The study looked at changes over time in individuals’ VO2max, a measure of aerobic fitness that refers to how much oxygen the body uses during a given activity. The VO2max is the point at which the body can no longer ramp up its oxygen use to keep up with the intensity of the exercise, and the activity rapidly becomes unsustainable.

It’s well known that a person’s VO2max declines with age. But the rate of that decline, Fleg explained, has not been clear-in large part because studies on the subject have typically compared different age groups rather than following the same people over time.

His team’s study included healthy men and women between the ages of 21 and 96 who periodically underwent treadmill tests to gauge their VO2max. The researchers also charted changes in participants’ blood pressure, body composition and lifestyle habits, over an average of eight years of follow-up.

In general, the study found, VO2max declined by 3 to 6 percent per decade while people were in their 20s and 30s. The rate of decline increased with age, going above 20 percent per decade among adults in their 70s or older.

The “good news,” Fleg said, is that active people maintained a higher VO2max than sedentary people their age, pointing to the importance of staying active throughout life.

He noted that older, sedentary adults who want to boost their fitness should consult their doctors before starting to exercise, as should anyone with heart disease.
