New research suggests that older adults undergoing voluntary surgery should undertake a continuous program of previously targeted exercises to counter the muscle wasting effects of bed rest.
A study published by researchers at the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences has shown that short-term ‘prehabilitation’ strength exercises, pre-surgery, are inadequate to prevent muscle loss.
In the study, researchers asked a group of older adults to do four sessions of weight-bearing exercise over a week. Participants exercised using only one leg, while the other leg did not exercise at all.
After completing rehabilitation, participants lay in bed rest for five days – a specific length of hospital stay for an older patient.
Although the researchers expected to find that the leg that had been exercised would experience less muscle loss than the other leg, in fact they found that the muscle loss in both legs was similar.
The team’s detailed analysis showed that short-term exercise rehabilitation increases the process of body muscle-building, with thigh muscle-wasting in both legs by about 3-4 percent – which older adults typically lose more than 3-5 Is equal to Years of aging.
Researchers suggest that one approach to prevent chronic muscle wasting during hospitalization is to practice strength exercises longer than before.
The study’s corresponding author, Dr. Leah Breen said, “Although short-term rehabilitation provides a cost-effective and easy-to-implement strategy, it does not prevent muscle wasting in bed-resting older adults.”
“Muscle loss can be extremely difficult to overcome and can lead to health and disease complications in the long run,” Bhreen said.
The team recommends that pre-exercise programs to prevent cardiovascular exercise should include strength training as well as aerobic exercise, and a protein-rich diet to increase muscle levels during bed rest. Will effectively rule out muscle loss occurring.
They also recommend that older patients hospitalized should aim to get back on their feet and on mobile as quickly as possible, where appropriate and safe.
Post-surgery exercise and dietary strategies will also be important to return to full health and reduce the risk of future health complications.
Now Dr. at Monash University, Australia. Benoit Sminninx is the lead author on the paper.
“Our study confirms the need for more research into the benefits of long-term training programs before surgery. In the same way that an athlete will train before a race or competition, exercise training before hospitalization is likely to be highly beneficial for older adults to undergo elective surgery, ”he said.
The work was completed in collaboration with colleagues within the Medical Research Council Versus Arthritis Center for Musculoskeletal Aging Research, a partnership between the University of Birmingham and the University of Nottingham.
The work was funded by the Biotechnology and Biological Sciences Research Council.
