Adults lose between 3 and 8 percent of their muscle mass per decade from age 30 onwards. The rate accelerates significantly after 50, and further accelerates after 60 without deliberate intervention. On the Isle of Man, as across the UK, this process is rarely discussed in primary care until it has progressed to the point of fall risk, functional limitation, or metabolic disease. By that point, years of preventable decline have already accumulated.
Why Muscle Mass Matters for Everything
Skeletal muscle is the primary site of glucose disposal after a meal. Reduced muscle mass means reduced capacity to clear blood glucose, which drives insulin resistance and eventually type 2 diabetes. Muscle mass also determines resting metabolic rate, meaning that its loss drives fat accumulation even without dietary changes. And muscle strength is the strongest predictor of falls, fractures, and disability in older adults: stronger people simply fall less and recover faster when they do.
The Clinical Solution: EMS and Resistance Training
Electrical muscle stimulation using clinical-grade EMS equipment produces muscle contractions equivalent to high-intensity resistance training in adults who cannot manage heavy resistance training due to joint pain, injury, or deconditioning. In 20-minute sessions, EMS activates over 90 percent of muscle fibres simultaneously compared to the 30 to 40 percent recruited in typical voluntary exercise. Clinical trials have demonstrated significant muscle mass gains in adults over 60 using EMS alone, without additional exercise.
