Predicting Muscle Loss in Older Adults
2010
What was this project about and why is it important?
The purpose of this project was to explore ways of detecting loss of muscle mass in older
adults with the least amount of time and equipment by measuring posture, walking, balance,
and nutrition.
This is important because the loss of muscle mass with age can cause muscle weakness and
this can contribute to falls.
Losing muscle mass (called sarcopenia) is a normal part of getting older. However, losing too
much muscle can increase the risk of falls. Falls can cause physical injuries (such as broken
bones) that can affect independence, day-to-day activities, and quality of life. Measuring
muscle mass helps identify people who are more likely to fall. There are many different ways
to measure muscle mass. These assessments can require special equipment and people who
have special training. If we can find a way to measure muscle mass easily and correctly, more
people with low muscle mass can be helped.
What did the research team do?
The research team tried out a number of different ways to measure muscle mass with
participants. Then they looked at all of the tools to see which ones could measure muscle
mass easily and correctly.
What did the research team find?
Two tests measured muscle mass correctly in most participants. These tests are the maximum
handgrip strength (which tells us how hard you can squeeze with your hand) and waist
circumference (which tells us the distance around your waist). With these tests, health
professionals can easily find out a person’s muscle mass.
How could this research be used in practice?
This research found two tests that can easily measure muscle mass. Health professionals can
use these tests to identify residents with low muscle mass and may be at risk of falling. Health
professionals can recommend lifestyle changes to improve or slow down the loss of muscle
mass in these residents. This may include choosing foods that are high in protein and/or
becoming more physically active with strength training. As a result, residents will improve or
maintain their muscle mass and reduce the risk for falls.
