Preventing Falls in Older Adults: What the Research Really Says About Strength, Sarcopenia and Staying Independent

I recently attended some training from Exeter University on falls and thought I would share some of the key takeaways from it.

Falls are one of the leading causes of injury, hospital admission and loss of independence in older adults. However, despite common belief, falling is not simply an inevitable part of ageing.

Research consistently shows that many falls are preventable through a combination of strength training, balance work, environmental modification, good nutrition and maintaining meaningful physical activity throughout later life (Sherrington et al., 2019).

The latest National Institute for Health and Care Excellence (NICE) guidance highlights that falls prevention should focus on maintaining strength, balance, mobility, confidence and independence rather than simply trying to “be careful” (NICE, 2025).

At Physio@Home UK we regularly see how appropriate rehabilitation and targeted exercise can help people regain confidence, improve mobility and remain independent for longer.

Why Do Falls Happen?

Falls are rarely caused by a single factor. Most falls occur due to a combination of physical, environmental and medical contributors.

Common risk factors include:

• Muscle weakness

• Reduced balance

• Reduced walking speed

• Joint pain and osteoarthritis

• Vision or hearing problems

• Reduced confidence

• Medication side effects

• Inactivity and deconditioning

• Poor nutrition

• Home hazards

• Frailty and sarcopenia

NICE recommends that falls prevention should involve a “multifactorial assessment,” meaning clinicians should consider the whole person rather than focusing on one isolated issue (NICE, 2025).

For example, somebody may fall due to a combination of:

• leg weakness,

• poor lighting,

• reduced confidence,

• medication side effects,

• and reduced balance following illness.

Addressing only one factor is often not enough.

What Is Sarcopenia?

One of the most important contributors to falls is sarcopenia.

Sarcopenia refers to the progressive loss of muscle mass, strength and physical function associated with ageing (Volpi et al., 2004).

Although some muscle loss occurs naturally with age, inactivity is one of the biggest drivers of decline.

Periods of:

• illness,

• hospital admission,

• surgery,

• pain flare-ups,

• or prolonged rest

can accelerate muscle loss dramatically.

Research suggests adults may lose approximately 3–8% of muscle mass per decade after the age of 30, with the rate increasing significantly after 60 years old (Volpi et al., 2004).

Importantly, sarcopenia is not simply about smaller muscles. It also affects:

• reaction speed,

• coordination,

• balance,

• walking speed,

• power,

• and the ability to recover from trips or slips.

This creates a vicious cycle:

1. Reduced strength leads to reduced activity.

2. Reduced activity causes further muscle loss.

3. Muscle loss increases falls risk.

4. Fear of falling then reduces activity even more.

Many older adults notice this after:

• a hospital stay,

• a chest infection,

• a fracture,

• or a period of immobility.

The phrase “use it or lose it” is strongly supported by research. Functional decline can occur surprisingly quickly during inactivity, and many people never fully regain their previous baseline after repeated periods of illness or deconditioning (Gill et al., 2010).

The encouraging news is that sarcopenia responds extremely well to resistance training and regular

activity.

Resistance Training: One of the Most Effective Falls Prevention Strategies

The evidence supporting resistance training in older adults is now extremely strong.

Research consistently shows progressive strength training improves:

• Muscle strength

• Balance

• Walking ability

• Functional independence

• Confidence

• Bone health

• Falls risk

A large Cochrane Review by Liu and Latham (2009) found that progressive resistance training significantly improves physical function in older adults, including walking speed and chair rise performance.

Similarly, Peterson et al. (2010) demonstrated through meta-analysis that older adults remain highly responsive to strength training even into later decades of life.

Importantly, the latest NICE falls guidance specifically recommends exercise programmes that include:

• strength training,

• balance work,

• gait training,

• and functional movement practice (NICE, 2025).

What Type of Strength Training Actually Works?

This is where research becomes particularly important.

Very low-level exercise or non-progressive programmes are often insufficient to create meaningful physiological change.

Research supports:

• Moderate to high intensity resistance training

• Progressive overload

• Consistency

• Long-term participation

Older adults typically benefit most from:

• 2–3 strengthening sessions per week

• Exercises targeting major muscle groups

• Moderate to challenging resistance

• Gradual progression over time

Research commonly recommends training around 60–80% of one repetition maximum (1RM) for meaningful strength improvements (Peterson et al., 2010).

Progressive overload is essential. This simply means exercises must gradually become more challenging as strength improves.

Without progression, the body adapts and stops improving.

Examples of effective strengthening exercises include:

• Sit-to-stands

• Squats

• Step-ups

• Stair climbing

• Heel raises

• Resistance band exercises

• Weighted carries

• Gym-based strengthening

Lower limb strengthening is particularly important because reduced leg strength is strongly associated with falls risk.

Balance Training Is Equally Important

Strength alone is not enough.

Research consistently shows that balance-focused exercise significantly reduces falls risk (Sherrington et al., 2019).

Effective balance training may involve:

• Standing on one leg

• Tandem walking

• Direction changes

• Reaching exercises

• Turning practice

• Uneven surfaces

• Stepping drills

Programmes such as the Otago Exercise Programme and Tai Chi have shown strong evidence for reducing falls in older adults (Campbell and Robertson, 2003).

Tai Chi is particularly interesting because it combines:

• Balance

• Coordination

• Controlled movement

• Confidence building

• Cognitive engagement

while also often being enjoyable and social.

The latest NICE guidance recommends that exercise programmes should be:

• progressive,

• individualised,

• appropriately challenging,

• and reviewed regularly (NICE, 2025).

The Home Environment Matters

Many falls happen inside the home.

Environmental hazards become increasingly important when combined with reduced strength or balance.

Common risks include:

• Loose rugs

• Clutter

• Poor lighting

• Slippery flooring

• Difficult stairs

• Unsafe footwear

• Lack of handrails

• Pets underfoot

• Trailing wires

Research shows targeted home hazard assessment and modification can significantly reduce falls risk, particularly in higher-risk individuals (Clemson et al., 2008).

Simple changes can make a major difference:

• Installing grab rails

• Improving lighting

• Removing trip hazards

• Using non-slip mats

• Adding stair rails

• Improving bathroom safety

• Wearing supportive footwear

NICE also highlights the value of occupational therapist-led home assessments for individuals at higher falls risk (NICE, 2025).

Fear of Falling Can Increase Falls Risk

Fear of falling itself can become a major problem.

Many people understandably reduce activity after a fall or near miss. Unfortunately, avoiding movement often worsens:

• Strength

• Balance

• Mobility

• Confidence

which then increases future falls risk.

Research shows fear of falling is associated with reduced physical activity and worsening functional decline (NICE, 2025).

This is why rehabilitation should focus not only on physical strength, but also rebuilding confidence through graded exposure to movement and activity.

Staying Active After Illness Is Critical

One of the strongest messages from frailty and ageing research is that inactivity causes rapid decline.

Even relatively short periods of immobility can lead to:

• Muscle loss

• Reduced cardiovascular fitness

• Poorer balance

• Reduced walking ability

• Loss of independence

Older adults often lose significant function after:

• Hospital admissions

• Chest infections

• Surgery

• Falls

• Fractures

Unfortunately, many people never fully regain their previous baseline after repeated episodes of inactivity (Gill et al., 2010).

The latest NICE guidance strongly encourages maintaining movement and avoiding deconditioning wherever possible (NICE, 2025).

Nutrition and Muscle Health

Exercise alone is not enough if nutritional intake is poor.

Muscle strengthening and recovery require adequate dietary support.

Research suggests older adults undertaking resistance training or experiencing sarcopenia may benefit from protein intakes of approximately 1.2–1.5 g/kg/day (Bauer et al., 2013).

Older adults frequently consume insufficient protein, particularly during illness or periods of reduced appetite.

Important nutritional considerations include:

• Adequate protein intake

• Hydration

• Vitamin D

• Calcium

• Overall calorie intake

The Mediterranean diet is often recommended because it supports healthy ageing and general health outcomes.

This includes:

• Fish

• Olive oil

• Fruit and vegetables

• Nuts

• Legumes

• Whole grains

Exercise Needs to Be Enjoyable

One of the biggest reasons exercise programmes fail is poor long-term adherence.

Research consistently shows that people are more likely to continue exercise if it feels meaningful, enjoyable and socially engaging.

The best exercise programme is often not the “perfect” programme physiologically — it is the one somebody will actually continue long term.

This is where patient-centred rehabilitation becomes extremely important.

For some people this may mean:

• Walking groups

• Gardening

• Dancing

• Swimming

• Tai Chi

• Golf

• Water aerobics

• Community strength classes

• Cycling groups

Social activity itself can improve confidence and motivation.

Electric bikes are becoming increasingly popular because they:

• Reduce barriers related to hills and fatigue

• Encourage outdoor activity

• Improve cardiovascular fitness

• Support independence

• Help people remain socially connected

Regular enjoyable activity is far more sustainable than occasional bursts of intense exercise.

The latest NICE guidance also emphasises the importance of helping people maintain long-term participation in exercise rather than viewing rehabilitation as temporary (NICE, 2025).

The Most Important Message

The evidence is very clear:

• Falls are not simply an unavoidable part of ageing.

• Strength can improve at almost any age.

• Balance can improve.

• Confidence can improve.

• Independence can often be maintained for longer with the right support.

The strongest evidence supports:

• Progressive resistance training

• Balance-focused exercise

• Regular physical activity

• Home hazard reduction

• Good nutrition

• Maintaining meaningful social and physical engagement

Most importantly, movement should become a regular and enjoyable part of life rather than something only done after a fall occurs.

If you are struggling with:

• balance,

• falls,

• reduced confidence,

• weakness,

• or reduced mobility,

a physiotherapy assessment can help identify the main contributing factors and create an individualised rehabilitation plan to improve strength, confidence and independence safely.
