“…Despite positive results, the effect of WB-EMS was borderline non-significant (p=0.069) for abdominal body fat and almost completely absent for total body fat mass; thus, our secondary hypothesis was rejected. Although we did not primarily address the "sarcopenic obesity" phenomena (Stenholm et al 2008;Zamboni et al 2008), we did expect to significantly impact both muscle and (abdominal) fat in view of the positive findings of our pilot trials (Kemmler et al 2010a, b) and a cross-sectional study that specifically focused on energy expenditure during WB-EMS (Kemmler et al 2012). However, the fundamental difference between these pilot studies with elderly subjects either with osteopenia (women, 65±6 years) or the metabolic syndrome (men, 65±6 years) may be, that both cohorts were less lean (BMI, 25.9±4.1 and 27.8±3.5 kg/m 2 ) compared with the subjects of the present study.…”

“…Based on the previous results of our working group (Kemmler et al 2010a(Kemmler et al , 2010b(Kemmler et al , 2012, the WB-EMS protocol scheduled 18 min of supervised whole body electromyostimulation training three times in 2 weeks (every Monday or Tuesday and every second Thursday or Friday) for 54 weeks (total number of sessions, 80; total volume of the sessions, 24 h). In order to validate the isolated effect of WB-EMS and to blind participants, we implemented an active control group (aCG).…”

“…Strain or current intensity can be individually selected and modified during the EMS session. Our WB-EMS protocol scheduled the intermitted low intensity/low amplitude movement protocol specifically evaluated for elderly subjects and carefully described in our recent pilot studies (Kemmler et al 2010a(Kemmler et al , 2010b(Kemmler et al , 2012. Briefly, three subjects underwent video-guided exercise at three EMS stations under the supervision of a certified instructor.…”

“…WB-EMS is a technology that enables the simultaneous activation of the muscles of up to 16 regions with a total size of electrodes of 2.650 cm 2 and with different dedicated intensities per region. The first pilot trials with elderly subjects that focused on body composition (Kemmler et al 2010b), metabolic syndrome (MetSyn) parameters (Kemmler et al 2010a), energy expenditure (Kemmler et al 2010b(Kemmler et al , 2012 and functional capacity (Kemmler et al 2010a(Kemmler et al , 2010b generally resulted in positive outcomes. Also of importance, the acceptance of this technology by the participants was rather high (Kemmler et al 2010a(Kemmler et al , 2010b.…”

Most studies have confirmed the positive impact of resistance training on muscle mass and functional capacity in aging adults. However, due to physical limitation or a simple aversion against regular exercise, the majority of elderly subjects do not reach the exercise doses recommended for impacting strength or muscle mass. This led us to evaluate the effect of whole-body electromyostimulation (WB-EMS), a novel, timeefficient and smooth training technology, on body composition with special regard to sarcopenia. Seventy-six lean, non-sportive women (75±4 years) were randomly assigned to either a WB-EMS group (WB-EMS, n=38) that performed 18 min of WB-EMS (bipolar, 85 Hz) 3 sessions in 14 days (1.5 sessions/week) or a semi-active control group (aCG, n=38). Body composition was assessed by dual-energy X-ray absorptiometry and maximum strength was evaluated using isometric techniques for trunk and legs. After 54 weeks of intervention, significant inter-group differences were determined for appendicular skeletal muscle mass (WB-EMS, 0.4±2.2 % vs. aCG, −1.5±3.1 %; p=0.009), lean body mass (WB-EMS, 0.8±1.8 % vs. aCG, −0.8±2.7 %; p=0.008) and maximum isometric strength (leg extensors, 9.8±12.9 % vs. 0.2±10.4 %; p=0.003; trunk extensors, 10.1±12.7 vs. −1.6±8.6 %; p=0.001). Although borderline significant for abdominal fat mass (WB-EMS, −2.9±8.3 vs. aCG, 1.5±10.7 %; p=0.069), differences did not reach statistically significant levels for body fat parameters. Considering the clinical effectiveness for impacting sarcopenia and the good acceptance of this technology by this non-sportive cohort of elderly women, we conclude that for elderly subjects unable or unwilling to perform dynamic strength exercises, electromyostimulation may be a less off-putting alternative to maintain lean body mass and strength.

“…LB-EMS application is an effective training method to enhance lower body power that provides intense contraction to the stimulated leg muscles and thereby induces greater adaptive responses. Local EMS application have shown positive effects on neuromuscular parameters in athletes and healthy individuals; however; there are a few multi-joint EMS studies on the effects of athletic performance and therefore, the feasibility and acceptability of this new training technology have turned out to be an important point (Kemmler et al, 2012;Kraemer and Mendryk, 1982;Kale et al, 2014;Komi, 2008, Vanderthommen andPorcari et al, 2002).…”

Abstract:Electromyostimulation is commonly used for potentiation of muscle strength to supplement voluntary muscle contractions. However, the acute effects of the lower body electromyostimulation on muscle strengthening are poorly known. Fourteen moderately trained men exposed to three lower body electromyostimulation sessions in nonconsecutive days under experimental conditions (30Hz, 100Hz) and control condition (0Hz). Each subject participated in post-tests including squat jump, countermovement jump and dominant concentric knee extension-flexion isokinetic strength at 60, 180, 300ºs-1. All tests performed 90 seconds after a single bout of lower body electromyostimulation with 90º static squat position for 16 seconds (4s Electromyostimulation/4s rest) at maximal tolerated current intensity. Statistical analysis have shown that there are significant increases in jump heights (p<0.05), rating perceived exertion (p≤0.001) and knee flexion torques at 180 and 300ºs-1 angular velocities (p<0.05) for acute electromyostimulation with two experimental conditions compared to control condition. Postactivation potentiation effect of conditioning contractions can be responsible for mechanism under these significant differences. However, there were no significant differences between low and high frequencies regarding 60º, 180º, 300ºs-1 extension and 60ºs-1 flexion knee isokinetic torques (p>0.05) and all jump values (p>0.05). In conclusion, lower body electromyostimulation at low or high frequencies can increase explosive strength regarding high-speed flexion torques and jump height in acute phase of moderately trained men.
