Muscle Strength and Healthy Ageing

Climbing stairs, carrying shopping and rising from a chair are ordinary activities. Preserving their ease gives healthy ageing a practical meaning, making muscle strength relevant to a longevity discussion.

Why assess strength?

Force production matters to everyday function. Significant weakness should not simply be dismissed as inevitable ageing. Sarcopenia is a clinical condition involving loss of muscle health, not a diagnosis made from a photograph or body weight alone. Strength, muscle quantity and physical performance may all be assessed. [4]

Is walking enough?

Walking is an accessible form of activity, but general recommendations also include resistance-based muscle strengthening. WHO recommends 150–300 minutes of moderate aerobic activity weekly or an equivalent vigorous amount, plus strengthening major muscle groups on at least two days. These population targets need adaptation to health, starting level and mobility. [1,2]

What is resistance exercise?

It involves muscles working against resistance provided by body weight, bands, free weights or suitable equipment. An appropriate programme matters more than the equipment type. People with significant weakness may benefit from planning with a physiotherapist or relevant exercise professional. [4]

What did the LISA follow-up find?

The 2024 follow-up report concerned a trial initially allocating 451 people around retirement age to one year of supervised heavy resistance training, moderate exercise or a control group. At four years, 369 participants were reassessed.

A particular measure of isometric leg strength remained near baseline in the heavy-training group and declined in the others. This does not mean everyone should begin with heavy weights. Participants were relatively healthy, well-functioning older adults, limiting generalisation to every patient or age group. The study measured muscle function, not lifespan or years of life added. [3]

Starting priorities

Establish a sustainable routine, learn technique and increase resistance as capacity develops. No single exercise or load prescription suits everyone. [4]

• Identify everyday movements you find difficult.
• Make space for both aerobic and strength activities.
• Consider balance work, particularly in later life.
• Track ease of daily tasks alongside appearance.

Balance and coordination alongside strength are important parts of activity planning in older age. [1]

What to discuss with your doctor

Share recent strength changes, falls, symptoms during movement and existing conditions. Assessment and referral can be tailored when needed. A healthy-ageing plan can begin with the daily functions you most want to preserve.
