2026/10/12

Scientists at Chiba University in Japan used advanced imaging to see inside the calf during EMS. Twenty-four healthy men used a leg EMS trainer for just 15 minutes. The main calf muscle’s activity score jumped about 173%. Front shin muscles rose about 175%, even without pads on them. A second test confirmed higher muscle fluid. A control test with the device switched off showed no change. The study was peer-reviewed and published in a respected UK journal. Results suggest EMS may suit people

Scientists at Yonsei University in South Korea ran a randomised trial with 50 healthy adults. Volunteers used an Ab EMS trainer for 23 minutes, twice a day, for 8 weeks. One group added crunches. MRI scans showed the six-pack muscle grew about 21–25% in both groups. Side ab muscles grew up to 9%. Core control improved too, by up to 70% when EMS was paired with exercise. The study was published in the peer-reviewed Journal of Sport Rehabilitation. It suggests EMS may support fitness in healthy

2026/10/11

Scientists at Northern Illinois University tested abdominal EMS in 38 healthy men and women. They measured energy use, heart rate, and breathing at rest and while walking.EMS raised energy expenditure by 19.4% at rest and 4.4% during walking. Heart rate rose 14.3% at rest and 8.3% while walking. Fat use also increased during walking. Men and women responded the same. Results were strong even at different comfort levels. These findings show abdominal EMS can boost metabolism and cardiorespiratory

2026/10/11

Scientists tested full body EMS on 40 sedentary overweight women (BMI 25–29.9, ages 20–45). One group did aerobic exercise three days a week. The other did the same plus full body EMS two days a week for 20 minutes. Both followed a 500-calorie deficit diet for six weeks. They measured weight, body fat percentage, waist and hip size, abdominal and suprailiac skinfolds, and soft lean mass using scales, tape, calipers, and bioimpedance. Both groups improved. The full body EMS group cut abdominal

Does EMS Improve Performance?

Health Research Digest with Leo and Eva ·

2026/10/11

Scientists tested spinal cord stimulation (SCS) in people with spinal injuries during exercise. They measured blood pressure, oxygen use, and how long athletes could keep going. One study found a 26 percent rise in peak oxygen uptake. Another showed athletes lasted up to 19 minutes longer, with an average 48 percent better performance. These results suggest SCS can help people with spinal cord injury exercise harder and longer by supporting blood flow and reducing limits from low blood

2026/10/10

Scientists measured every breath in 40 healthy sedentary adults while EMS pads worked the belly, buttocks, and thighs. At a visible muscle contraction, oxygen use rose from 0.227 to 0.252 litres a minute. At the strongest comfortable level it reached 0.265, and calories climbed from 65 to 76 an hour. The lift was still there in recovery. Higher stimulation intensity meant more energy expenditure, in a straight line. Fat stayed a major fuel. Age, sex, and body size did not change the extra

2026/10/08

Scientists in Athens tested whether electrical muscle stimulation could slow muscle loss in critically ill patients who could not exercise. A randomised hospital study used ultrasound to measure the rectus femoris and vastus intermedius on day two and again one week later. Both groups lost muscle. The stimulation group lost less. Right thigh size fell about 8% and 12.5% with daily sessions, versus about 13.9% and 21.5% with usual care. Those gaps were significant. Published in Critical Care by a

2026/10/08

A team at the University of Bologna, with colleagues in Trento and the United States, pooled five fair tests of walking versus other exercise for chronic low back pain. The trials included 329 adults, average age about 43. Pain, disability, quality of life, and fear of movement improved in a similar way in both groups. The differences were small and not statistically significant at short, mid, and long follow-up. Adding walking to exercise did not clearly add a short-term gain. The paper is a

2026/10/08

Doctors in New York reviewed 20 studies on muscle stimulation, covering 521 people. Their 2022 paper ran in Dermatologic Surgery, published by Wolters Kluwer in the United States. Teams at Hofstra/Northwell and UnionDerm graded the proof. MRI, CT, and ultrasound measured the change. On the abdomen, muscle thickness rose about 15 to 21 percent. Fat thickness fell about 15 to 20 percent. Some of that change lasted one year. Postpartum women showed a smaller muscle gap. Arms and calves thickened too

University scientists tested 21 college baseball pitchers in three simulated five-inning games. Each game had up to 70 fastballs. After every inning, pitchers sat, used an arm bike, or used EMS on the throwing arm for six minutes. Researchers measured heart rate, effort, arm motion, and blood lactate. Only EMS cut lactate, from 3.85 to 2.01. Sitting left it flat. The bike raised it. Eighteen of 21 pitchers preferred EMS. A peer-reviewed US strength journal published the work. That evidence

Scientists in France and the United States put EMS to the test. They did not guess. They measured muscle strength, jump height, kick speed, muscle size, nerve drive, and blood lactate.Young gymnasts gained knee strength of about 35% to 51% in three weeks. Soccer players kicked faster after five weeks. One lab found strength up 27% in eight weeks, with more muscle mass. Pitchers cleared lactate better with EMS than with jogging. Swimmers cleared more lactate with EMS than with sitting still. The

Sydney scientists tested EMS cycling in seven women with advanced multiple sclerosis. They ran 18 sessions of 40 minutes. Current rose slowly. Pedal speed stayed at 10 rpm. They measured current, power, heart rate, oxygen use, and thigh size. Peak EMS reached 91 mA in the thighs. That was higher than an older MS study. Estimated thigh volume rose 10.7% and 11.6%. Heart rate rose from 67 to 85. Oxygen use more than doubled. Many rated transfers better. The findings suggest EMS can help people with

University labs in Germany and Spain tested full body EMS in a real science journal. They timed runs and skates. They measured oxygen use, jump height, leg strength, and muscle size. After six short sessions, runners used more oxygen and needed less effort at the same pace. Hockey players skated 10 metres 5% faster and jumped with 5.15% more power. Soccer players got stronger legs. People eating less kept more muscle. These results suggest full body EMS can help runners, team players, and busy

Scientists in Berlin asked a simple question. Can EMS-style FES help people whose legs are paralysed swim better?They studied two men with complete paraplegia after spinal cord injury. Both could already do front crawl with their arms. For 10 weeks they swam in a 16 m pool. Staff timed laps with no help, with FES on the thighs, and with FES plus extra back stimulation. FES made average laps about 15.4% and 8.7% quicker. Both together made them about 19.3% and 20.9% quicker. Water-proof sensors

2026/09/25

A 2024 Springer book by German university scientists reviewed many trials of whole body EMS. They tracked muscle mass, strength, walking speed, and back-pain scores. A meta-analysis found a lean-mass effect of 1.23. Over 30 studies measured maximum strength. Once-weekly sessions beat a four-day clinic plan on pain and daily tasks. Older adults often gained hip and knee strength. That evidence suggests a coached full body EMS system may help busy people, sore backs, and limited joints. Read

Scientists at Teikyo Heisei University tested home EMS in 19 older adults aged 61–78.They scanned the quadriceps with ultrasonography, measured knee strength, and took fasting blood. After one 30-minute session, free fatty acids rose from 523.3 to 606.9 µEq/L and glucose rose from 96.4 to 98.8 mg/dL. After 12 weeks, intramuscular fat, thickness, and strength did not clearly change. The paper in the European Journal of Applied Physiology, from Springer Nature, still treats that short-term blood

2026/09/25

Four national team judo athletes at Hashemite University, did 20 EMS sessions in 28 days. Scientists measured isometric and isokinetic peak torque on a Cybex II at 0, 60, 90 and 120°/s. Left-leg extension at 60°/s rose from 119.50 to 151.50 Nm after the block, then eased 45 days later. Weight, fat and girth stayed flat. That evidence suggests EMS can help sport training for elite judoka and other weight-class users, and the authors also flag swimmers, sprinters and hockey players. Published 2013 in

A 2022 PeerJ trial tested EMS in 60 collegiate male football players. Both groups trained three days a week for eight weeks with plyometric drills and quadriceps strength work. One group used real NMES. The other used sham pads. Scientists measured thigh force, a 50-metre sprint, and a single-leg triple hop. Real EMS lifted strength from 145 to 215 and cut sprint time from 9.19s to 7.91s. The sham group gained less. Majmaah University led the work with UK partners. These figures suggest EMS can

Scientists in Brazil tested EMS in 30 recreational male distance runners aged 30–45.Fifteen men added six weeks of NMES on the quadriceps—three 15-minute sessions a week—plus usual running. Fifteen only ran. A dynamometer tracked isometric, concentric and eccentric peak torque. Treadmill gas tests tracked VAT1, VO2max and oxygen cost of transport. The EMS group gained 21.04% isometric, 21.97% concentric and 18.74% eccentric torque, plus 9.56% VAT1 and better economy at that threshold
