Quick Overview
You’re starting to notice it — getting up from chairs feels harder, walks tire you more quickly, and your strength isn’t what it used to be. New research from Professor Volker Adams at Germany’s respected TU Dresden Heart Center, published in a leading scientific journal, found something specific: consistent EMS use can increase muscle mass by around 1% and improve muscle function by 10–15% in just 5–6 weeks. One study even showed 30% larger thigh muscles in adults over 75.
This matters because maintaining strength helps you stay independent and active as you age. Backed by multiple human studies from a credible researcher, it offers real hope and practical options. Here’s what the science actually shows.

EMS Helped Increase Muscle Size by 30% in Adults Over 75
You’re starting to notice it.
Getting up from a chair feels a little harder than it used to. You tire more quickly on walks. The strength you once took for granted seems to be quietly slipping away. It’s a common experience as we get older, and many people quietly worry about losing their independence and ability to enjoy life the way they want to.
This is exactly what researchers in Germany decided to investigate.
Professor Volker Adams from the TU Dresden Heart Center carefully reviewed the evidence on EMS technology. His findings were published in the Journal of Cachexia, Sarcopenia and Muscle, a respected scientific journal from one of the world’s most trusted scientific nations. This wasn’t marketing material — it was a thorough look at studies involving real people, examining what EMS can realistically offer.
What the research discovered
The results were genuinely encouraging for people who want to stay strong as they age.
Studies showed that consistent use of EMS can increase muscle mass by around 1% and improve muscle function by 10–15% in just 5 to 6 weeks.
In one study with adults over 75, participants saw their thigh muscles grow by around 30% after several months. Even more importantly, EMS improved functional movements more effectively than regular exercise in some sedentary older adults.
The research also found that EMS appears particularly good at protecting the type of muscle fibres that help with everyday strength and stability — the very ones that tend to decline with age.
How EMS can help as we get older
EMS works by gently stimulating your muscles to contract, similar to normal movement but often reaching deeper muscle fibres. At a basic level, it helps create the conditions for your body to maintain and build muscle more effectively. Some forms of Whole body EMS, delivered through a Full body EMS system, allow multiple muscle groups to be worked at the same time in a relatively short session.'
For many older adults who find traditional gym workouts tiring or difficult, this offers a gentler yet effective way to keep muscles active. The research suggests it can be a valuable support for staying strong, mobile, and independent for longer.
Importantly, the review found that EMS can be used safely when started gradually and used with proper settings. While some people experience temporary changes in certain blood markers after their first few sessions, these effects generally settle with regular use.
The hopeful part
Getting older doesn’t have to mean steadily losing strength. The science shows there are ways to support your muscles and help maintain the physical capability that lets you keep doing the things you love.
This research from a credible German professor, published in a serious scientific journal, gives real evidence that EMS technology can be a helpful tool for people who want to stay active and independent as they age. It’s not about turning back the clock completely, but about giving your body meaningful support so you can keep living life on your terms for as long as possible.
If you’ve been noticing changes in your strength and wondering what you can do about it, the findings offer something genuinely positive to consider.

| Key Detail | Supporting Evidence from the Paper |
|---|---|
| EMS increases muscle mass after treatment | Studies show EMS can increase muscle mass by around 1% after 5–6 weeks of treatment |
| EMS improves muscle function | Muscle function improves by around 10–15% after 5–6 weeks of EMS application |
| Significant muscle growth in older adults | A 4-month EMS intervention (48 sessions) in subjects over 75 years increased rectus femoris cross-sectional area by around 30% |
| Superior functional improvement vs voluntary training | In sedentary seniors, EMS improved functional performances more effectively than voluntary leg press training |
| Protection against sarcopenia-related changes | EMS counteracted fast type muscle fibre atrophy, which is typically associated with sarcopenia |
| Recommended pulse characteristics | Stimulation should use biphasic current with large pulses between 300–450 µs |
| Recommended frequency by age group | High frequency of 50–100 Hz is advised for young individuals, while around 30 Hz is recommended for older individuals |
| Minimum treatment frequency and duration | A minimum of three sessions per week for at least 5–6 weeks should be performed |
| Intensity guideline | EMS intensity should be as high as individually tolerated |
| Safety regarding creatine kinase | Extremely high creatine kinase concentrations (up to 117-fold above baseline) were reported after initial sessions, yet no rhabdomyolysis-induced complications occurred |
| Adaptation of CK response over time | The CK rise is blunted after several sessions and averages in the range of conventional resistance training |
| Effect on anabolic and catabolic pathways | EMS stimulates anabolic pathways (e.g., IGF-1 secretion) and negatively modulates catabolic metabolism (e.g., MafB and MuRF1 expression) |
| Impact on myostatin and satellite cells | EMS effectively downregulates myostatin mRNA and increases the regenerative capacity of satellite cells |
| Clinical value for specific populations | EMS is positioned as a valuable tool for sarcopenic or CHF patients who cannot qualify for or comply with conventional exercise programs |
| Position relative to voluntary exercise |
EMS should not be regarded as a replacement for exercise training, as voluntary exercise provides additional benefits on endothelial, myocardial, and cognitive function |
