As we age, maintaining strength and independence becomes increasingly important. Yet many older adults experience a gradual loss of muscle mass and strength without realising there is a name for it. This condition, known as sarcopenia, is a common age-related challenge that can affect mobility, balance, and overall quality of life.
While some muscle loss is a natural part of ageing, sarcopenia is more than simply "getting older." Left unaddressed, it can make everyday activities more difficult and increase the risk of falls, frailty, and loss of independence. The good news is that there are practical steps older adults can take to help maintain muscle health and stay active for longer.
What Is Sarcopenia?
Sarcopenia refers to the progressive loss of muscle mass, strength, and function that occurs with age.
According to the National Institute on Aging, muscle mass and strength typically increase through early adulthood, peak around the ages of 30 to 35, and then gradually decline over time. This decline tends to accelerate later in life, particularly after age 65 for women and age 70 for men.
While this process is common, it is not something that should simply be accepted without action. Maintaining muscle health plays an important role in supporting independence, mobility, and overall wellbeing.
Why Muscle Mass Matters More Than You Think
Many people associate muscle with physical appearance, but muscle tissue does far more than help us move.
According to Science Insights, skeletal muscle plays a vital role in overall health. It helps regulate blood sugar, supports bone strength, contributes to metabolism, and assists with recovery from illness or injury.
Muscle mass also affects everyday function.
Strong muscles support many everyday activities, from climbing stairs and carrying groceries to maintaining balance and independence. When muscle strength declines, even routine tasks can become more challenging.
Common Signs of Sarcopenia
Sarcopenia often develops gradually, making it difficult to recognise at first.
Some common signs include:
-
Feeling weaker than usual
-
Difficulty climbing stairs
-
Slower walking speed
-
Reduced balance and stability
-
Difficulty carrying everyday items
-
Increased fatigue during physical activity
-
Loss of muscle size
Many people mistakenly assume these changes are simply part of ageing. However, recognising the signs early can help older adults seek support and take steps to maintain their physical function.
How Sarcopenia Affects Healthy Ageing
Muscle strength plays a major role in healthy ageing.
As muscle mass declines, the risk of several health concerns may increase, including:
-
Falls and fractures
-
Reduced mobility
-
Frailty
-
Loss of independence
-
Longer recovery after illness or injury
The National Institute on Aging notes that sarcopenia is associated with an increased risk of falls, serious injuries, and poorer health outcomes in later life.
For many older adults, the greatest concern is not the loss of muscle itself but the impact it can have on maintaining an active and independent lifestyle.
Why Exercise Is One of the Best Defences Against Sarcopenia
If there is one message to remember about sarcopenia, it is this: muscles respond to use.
The Australian Institute for Musculoskeletal Science and Sport (AIMSS) highlights the importance of regular physical activity in maintaining muscle mass and strength. In simple terms, the principle of "use it or lose it" applies strongly to muscle health.
Regular exercise can help:
-
Maintain muscle strength
-
Improve balance and mobility
-
Support bone health
-
Reduce the risk of falls
-
Enhance overall physical function
Research supported by the National Institute on Aging suggests that a combination of walking and resistance training is particularly effective for improving physical function in older adults.
What Types of Exercise Help?
A balanced exercise routine may include:
-
Strength or resistance training
-
Walking and aerobic activities
-
Balance exercises
-
Flexibility and mobility exercises
The most effective programs are often tailored to an individual's abilities, goals, and health needs.
Because muscle loss and frailty are closely linked, staying active becomes increasingly important with age. If you'd like to learn more about the connection between movement and healthy ageing, read our blog Frailty in Seniors: Why Movement Is More Important Than Ever.
Nutrition and Sarcopenia: Why Food Matters
Exercise is important, but nutrition also plays a key role in maintaining muscle health. According to AIMSS, older adults may need adequate protein intake to help preserve muscle mass as they age.
Good sources of protein include fish, lean meats, eggs, tofu, legumes, nuts, and seeds. For some people, working with a dietitian can also help ensure their nutritional needs are being met.
Small Changes Can Make a Big Difference
One of the most encouraging things about sarcopenia is that positive changes do not always require dramatic action.
Small, consistent habits can support muscle health over time.
Examples include:
-
Taking a daily walk
-
Participating in strength-based exercise
-
Staying physically active throughout the day
-
Including protein with meals
-
Remaining socially engaged in group activities
-
Seeking professional support when needed
The goal is not to become an athlete. The goal is to maintain strength, confidence, and independence for as long as possible.
How Summit Strong Supports Muscle Health
At Summit Health Solutions, we understand that maintaining strength is an important part of healthy ageing.
That's why Summit Strong supports older adults through a combination of personalised exercise, nutrition support, and social connection. This program is supported by funding from the ACT PHN through the Australian Government's PHN Program.
Participants receive guidance designed to help improve mobility, strength, and confidence through structured exercise and ongoing support. Where appropriate, additional nutrition guidance may also be available to help support overall wellbeing.
By addressing multiple factors that contribute to healthy ageing, Summit Strong helps participants maintain physical function and continue doing the activities they enjoy.
Stronger Muscles Support Greater Independence
While sarcopenia is common, it is not something older adults need to face passively.
Regular movement, strength training, good nutrition, and early intervention can all help support muscle health and physical function later in life.
By understanding sarcopenia and taking practical steps to stay active, older adults can help protect their independence, improve their quality of life, and continue enjoying the activities that matter most.
Frequently Asked Questions
What is sarcopenia?
Sarcopenia is the age-related loss of muscle mass, strength, and physical function. It becomes more common as people get older and can affect mobility, balance, and independence.
What causes sarcopenia?
Ageing is a major factor, but inactivity, poor nutrition, chronic health conditions, and illness can also contribute to muscle loss over time.
Can sarcopenia be prevented?
While some age-related muscle loss is normal, regular exercise, strength training, adequate protein intake, and healthy lifestyle habits can help slow or reduce its impact.
What exercises are best for sarcopenia?
Strength or resistance training is considered one of the most effective ways to maintain muscle mass. Walking, balance exercises, and mobility activities can also support overall physical function.
How does Summit Strong help older adults maintain strength?
Summit Strong combines personalised exercise support, nutrition guidance, and social connection opportunities to help participants improve strength, mobility, and overall wellbeing as they age.
