Muscle Loss Risk Screening
Sarcopenia (sar-co-PEE-nee-ah) is the gradual loss of muscle mass and strength that happens as we age. It can start as early as your 30s, but the good news is: it's preventable and even reversible with the right exercise and nutrition.

Sarcopenia is the age-related loss of muscle mass, strength, and physical function. The word comes from the Greek "sarx" (flesh) and "penia" (loss). While some muscle loss is a natural part of ageing, sarcopenia goes beyond normal decline — it can significantly affect your independence, mobility, and quality of life.
Research shows that we lose 3-8% of our muscle mass per decade after age 30, with the rate accelerating after 60. By age 80, many people have lost 30-50% of their muscle mass compared to their peak. This loss doesn't just affect strength — it increases your risk of falls, fractures, disability, and even hospitalisation.
The SARC-F questionnaire, which inspired this screening tool, is a validated clinical tool used worldwide to identify people at risk of sarcopenia. It focuses on five key areas: Strength, Assistance walking, Rising from a chair, Climbing stairs, and Falls. Our screening expands on this with additional questions about exercise habits, nutrition, and grip strength to give you a more complete picture of your muscle health.
The most important thing to know is that sarcopenia is not inevitable. Regular resistance training, adequate protein intake, and staying physically active can prevent, slow, and even reverse muscle loss at any age. If this screening identifies risk factors, a physiotherapist can help you take the right steps.
Frequently Asked Questions
What is sarcopenia in simple terms?
Sarcopenia is the gradual loss of muscle mass, strength, and function that happens as we age. Think of it like your muscles slowly shrinking and getting weaker over time. It can make everyday tasks like climbing stairs, carrying groceries, or getting up from a chair more difficult. The good news is that with the right exercise and nutrition, you can slow it down or even reverse it.
What are the early signs of muscle loss?
Early signs include: feeling weaker when lifting everyday objects, needing the handrail on stairs, difficulty getting up from low chairs, slower walking speed, losing your balance more easily, and feeling tired during activities that used to be easy. Grip strength declining (struggling to open jars) is also a reliable early indicator.
Can you reverse muscle loss?
Yes! Research consistently shows that muscle loss can be slowed, stopped, and even partially reversed at any age. The most effective approach combines resistance training (strength exercises) with adequate protein intake. Studies show that even people in their 80s and 90s can build muscle with the right programme.
At what age should I worry about this?
Muscle mass naturally starts declining around age 30, losing about 3-8% per decade. The loss accelerates after age 50 and again after 70. However, this screening is most relevant for adults aged 40 and above, especially those who are sedentary or have noticed changes in their strength or mobility.
What exercises help prevent muscle loss?
Resistance training is the most effective exercise for preventing muscle loss. This includes bodyweight exercises (squats, push-ups, lunges), resistance band exercises, and weight training. Aim for at least 2-3 sessions per week, targeting all major muscle groups. Walking and balance exercises are also important for overall function.
Should I see a physiotherapist about this?
Yes, if you scored moderate or high risk, or if you've noticed changes in your strength, balance, or mobility. A physiotherapist can perform objective measurements of your muscle function, design a safe and progressive exercise programme, and monitor your progress. Early intervention gives the best outcomes.
