“…EMS suits used in this study enabled the simultaneous activation of eight pairs of muscle groups (both upper legs, both upper arms, buttocks, abdomen, chest, lower back, upper back, and latissimus dorsi) with selectable intensities for each region. Based on recommendations from available literature [9,21,[29][30][31], the stimulation frequency was selected at 85 Hz, the impulse-width at 350 µs, the impulse-rise as a rectangular application, and variable electrostimulation intensities relative to the maximum peak voltage. This study used 1 MT (maximal tolerance) as the maximum peak voltage, similar to calculating the maximal voluntary contraction as one maximal repetition [13].…”

Background and objectives: Electromyostimulation (EMS) has been shown to improve body composition, but what biomarkers it affects has not been investigated. The purpose of this study was to compare the EMS-effect of exercises with music on fatness and biomarker levels in obese elderly. Materials and Methods: Twenty-five women were randomly classified into a control group (CON) and EMS group (EMSG). EMS suits used in this study enabled the simultaneous activation of eight pairs with selectable intensities. Program sessions of EMS were combined with exercises of listening to music three times a week for eight weeks. Although both groups received the same program, CON did not receive electrical stimuli. Results: Compared with CON, a significant effect of the EMS intervention concerning decreased fatness, as well as an increased skeletal muscle mass and basal metabolic rate, were evident. Tumor necrosis factor-a, C-reactive protein, resistin, and carcinoembryonic antigen of biomarkers were significantly different in the groups by time interaction. Similarly, the positive changes caused by EMS were represented in lipoprotein-cholesterols. Conclusions: The results indicate that a significant effect due to the EMS intervention was found concerning body composition and biomarkers in obese elderly women.

“…Based on recommendations from available literature, the stimulation frequency was selected at 85 Hz, the impulse-width at 350 microseconds, the impulserise as a rectangular application, and variable electrostimulation intensities relative to the maximum peak voltage (160 V). Impulse duration was 6 s with a 4-s break between impulses [2,8,41,43,44]. For each group, a qualified instructor conducted 20-minute WB-EMS sessions 3 times a week on two non-consecutive days to allow for a rest interval of 48 hours between each session.…”

BACKGROUND: Although whole body electromyostimulation (WB-EMS) has been shown to improve body composition and muscle strength in several research studies, it has not been confirmed whether a dose-response effect using various impulseintensities exists and how they affect adipose tissue-derived adipokines (APK), body composition, and strength. OBJECTIVE: To investigate the dose-response effect of wearing a WB-EMS suit in conjunction with isometric exercise on adipokines (APK), body composition including thigh circumference, and thigh muscle strength in normal healthy men for 6 weeks. METHOD: Fifty-two male subjects were randomly assigned to one of four groups: control group (CON, n = 13), low impulseintensity (LII) group (n = 12), mid impulse-intensity (MII) group (n = 14), and high impulse-intensity (HII) group (n = 13). Low-, mid-and high-impulse intensities were set at 50%, 60% and 80% of maximum tolerance (1MT). Subjects in CON group wore WB-EMS suits, but did not receive any impulses. The WB-EMS suits used in this study enabled the simultaneous activation of eight muscle groups with selectable intensities. Stimulation frequency was selected at 85 Hz, impulse-width at 350 microsecond, and impulse-rise as a rectangular application. Impulse duration was 6 s with a 4 s break between impulses. The 20-minute WB-EMS sessions were combined with isometric exercises 3 times a week for 6 weeks. APK, body composition including thigh circumference, and isokinetic peak moment (PT) and work per repetition (WR) of the knee extensors and flexors were measured on Week 0, Week 2, Week 4, and Week 6. RESULTS: Compared with the CON group, 1) there was a significant group by time interaction difference in Resistin (P = 0.016). That is, Resistin increased in the CON and LII groups, but decreased in the MII and HII groups. These changes in Resistin for both groups began to appear at Week 4. 2) Body weight (P = 0.024) and muscle mass (P = 0.037) were significantly different in group by time interaction. The decrease of body weight in the HII group began to appear at Week 4. In particular, the level of muscle mass increased only in the HII group at Week 6. 3) There were significant group by time interaction differences in the circumferences of thigh subcutaneous fat (TSF) and thigh total fat (TTF) on right and left sides. The right TSF (P = 0.045) and TTF (P = 0.019) decreased from baseline to Week 6 in the HII group. These changes were similar to the left TSF (P = 0.038) and TTF (P = 0.011). The changes in the HII group showed a marked decrease at Week 6. 4) There were significant group by time interaction effects in the PT of the left knee extensor (P = 0.037) and PT of the right knee flexor (P = 0.012). These results were similar with the WR of the right knee flexor (P = 0.002) and the WR of the left knee flexor (P = 0.019) in the HII group, which were significantly higher than those of the other three groups at Week 4 and 6. CONCLUSIONS: WB-EMS administered at high impulse intensity can improve Resistin, body composition including...

“…Da dieses kombinierte Training meist mehrmals je Woche eingesetzt wird und die Problematik hoher CK-und Myoglobin-Konzentration nach WB-EMS Applikation trotz intensiver Beforschung (u. a. [5]) und korrespondierender Richtlinien [6] auch aktuell wieder heftig diskutiert wird [7,8], erscheint eine Einschätzung der muskulären Beanspruchung nach unterschiedlichen WB-EMS Protokollen sicher hilfreich, um weitere Empfehlungen aussprechen zu können. Ziel des vorliegenden Beitrags war es daher, eine Einschätzung der muskulären Beanspruchung (a) eines ausdauerorientierten kontinuierlichen WB-EMS Protokolls (superimposed WB-EMS) mit unterschiedlicher Stimulationsfrequenz (7 vs. 85 Hz) und (b) eines kraftorientierten, intermittierenden WB-EMS-Protokolls (85 Hz) vorzulegen.…”

“…Hohe Kreatinkinase-Konzentrationen nach WB-EMS werden insbesondere nach Erstapplikation mit exzessiver Impulsintensität berichtet [15]. Auch die vorliegende Untersuchung zeigte in diesem Kollektiv ohne jede vorherige WB-EMS Konditionierung nach hochintensivem, aber nicht ausbelastetem WB-EMS Protokoll CK-Konzentrationen (9055 ± 6424 IE/l) 5 im Bereich einer moderaten Rhabdomyolyse 6 , [19]. Die intraindividuelle Streuung der CK Werte liegt dabei sehr hoch (854-16621 IE/l), ein Umstand, der u. a. genetisch bedingt ist [20], und zu einer Einteilung in unterschiedliche "Respondertypen" (low vs. moderate vs. high) führte [20,21].…”

ZUSAMMENFASSUNGGanzkörper-Elektromyostimulation zeichnet sich durch das Alleinstellungsmerkmal aus, große Muskelgruppen simultan aber regional dezidiert und ggf. supramaximal stimulieren zu können. Diese Konstellation kann zu gesundheitlichen Risiken führen, die unter dem Begriff der „Rhabdomyolyse“ subsumiert werden. Ziel dieses Beitrags war es, unterschiedliche WB-EMS-Protokolle hinsichtlich ihrer muskulären Belastung im Crossover-Verfahren zu überprüfen, um Empfehlungen für deren Applikation abzuleiten. Neunzehn sportliche Männer (28±5 Jahre) ohne jede WB-EMS Erfahrung wurden randomisiert und balanciert den WB-EMS-Protokollen Ausdauertraining (a) ohne (b) mit niedrig-moderat intensivem WB-EMS Dauerstrom-Protokoll mit 7 Hz bzw. (c) 85 Hz sowie Körperübungen (d) ohne bzw. (e) mit hoher, intermittierender (4s – 4s) Impulsintensität (85 Hz) zugeordnet. Es wurde bipolarer Strom mit einer Impulsbreite von 350 µs und direktem Impulsanstieg/-abfall appliziert. Die Dauer des Körperübungsprotokolls lag bei 20 min, das Ausdauerprogramm (75% VO2max, Crosstrainer) dauerte 30 min. Als Marker der muskulären Belastung wurde Kreatinkinase unmittelbar vor/nach, sowie 24, 48 und 72 h nach dem Test bestimmt. Alle Ausdauervarianten zeigten einen relativ moderaten Anstieg der CK-Konzentration um das 2,5–3 fache des Vorbelastungswertes mit Peak nach 48 h. Zwischen den Gruppen ohne und mit bzw. hoher und niedriger Stimulationsfrequenz konnten kein signifikanter Unterschiede erfasst werden. Die „kraftorientierte“ WB-EMS-Variante führte zu einer 48fachen Erhöhung des Vorbelastungswertes mit Peak nach 72 h. Faktisch kein Einfluss auf die CK-Konzentration hatten die Körperübungen ohne WB-EMS. Wie zu erwarten zeigen sich signifikante Unterschiede hinsichtlich der CK-Kinetik zwischen einem ausdauer- und kraftorientierten WB-EMS-Protokoll, die primär der unterschiedlichen Impulsintensität geschuldet sind. Diese Ergebnisse sind bei Empfehlungen zu Regenerationsdauer und Trainingshäufigkeit unterschiedlicher WB-EMS-Protokolle zu berücksichtigen.
