Whole-Body Electromyostimulation (WB-EMS) is a training technology that enables simultaneous stimulation of all the main muscle groups with a specific impulse intensity for each electrode. The corresponding time-efficiency and joint-friendliness of WB-EMS may be particularly attractive for people unable or unmotivated to conduct (intense) conventional training protocols. However, due to the enormous metabolic and musculoskeletal impact of WB-EMS, particular attention must be paid to the application of this technology.

Article Synopsis
  • The study compared three training methods—whole-body electromyostimulation (WB-EMS), whole-body vibration (WBV), and conventional back-strengthening training (CT)—on reducing mean back pain intensity (MPI) and improving trunk strength in patients with chronic non-specific low back pain (CNLBP).
  • All groups showed a significant reduction in MPI and improvement in trunk strength after 12 weeks, with comparable results across the different training methods.
  • Despite similar effectiveness, WB-EMS required 43-62% less training volume compared to CT and WBV, indicating that it may be a more efficient option for patients.

Intramuscular density of monocarboxylate-transporter (MCT) could affect the ability to perform high amounts of fast and explosive actions during a soccer game. MCTs have been proven to be essential for lactate shuttling and pH regulation during exercise and can undergo notable adaptational changes depending on training. The aim of this study was to evaluate the occurrence and direction of potential effects of a 7-weeks training period of jumps with superimposed whole-body electromyostimulation on soccer relevant performance surrogates and MCT density in soccer players.

Whole-body electromyostimulation (WB-EMS) gained increasing interest in sports within recent years. However, few intervention studies have examined the effects of WB-EMS on trained subjects in comparison to conventional strength training. The aim of the present mini-meta-analysis of 5 recently conducted and published randomized controlled WB-EMS trails of our work group was to evaluate potentially favorable effects of WB-EMS in comparison to conventional strength training.

Background: Low back pain (LBP) affects almost everyone at least once in their lifetime. Various meta-analyses show promising effects on pain reduction for conventional exercise. However, the lack of time and, especially for pain patients, a fear of movement ("kinesiophobia") as well as functional limitations often oppose participation in such activities.

The aim of this study was to compare the effects of short-term strength training with and without superimposed whole-body electromyostimulation (WB-EMS) on straight sprinting speed (SSS), change of direction speed (CODS), vertical and horizontal jumping, as well as on strength and power in physically active females. Twenty-two active female participants ( = 22; mean ± SD: age: 20.5 ± 2.

The purpose of this study was to assess the effects of dynamic superimposed submaximal whole-body electromyostimulation (WB-EMS) training on maximal strength and power parameters of the leg muscles compared with a similar dynamic training without WB-EMS. Eighteen male sport students were randomly assigned either to a WB-EMS intervention (INT; = 9; age: 28.8 (: 3.

The aim of the present study was to investigate the effects of a multiple set squat exercise training intervention with superimposed electromyostimulation (EMS) on strength and power, sprint and jump performance. Twenty athletes from different disciplines participated and were divided into two groups: strength training (S) or strength training with superimposed EMS (S+E). Both groups completed the same training program twice a week over a six week period consisting of four sets of the 10 repetition maximum of back squats.

Intensive exercise like strength training increases blood lactate concentration [La]. [La] is commonly used to define the metabolic stress of an exercise and depends on the lactate production, transportation, metabolism, and elimination. This investigation compared multiple set training of different volumes to show the influence of exercise volume on [La].

The present study aimed to investigate the relationship between the mechanical load during resistance exercise and the elicited physiological responses. Ten resistance-trained healthy male subjects performed 1 set of resistance exercise each at 55%, 70%, and 85% of 1 repetition maximum for as many repetitions as possible and in 4 training modes: 4-1-4-1 (4 s concentric, 1 s isometric, 4 s eccentric, and 1 s isometric successive actions), 2-1-2-1, 1-1-1-1, and explosive (maximum velocity concentric). Mean concentric power and total concentric work were determined.

Synopsis of recent research by authors named "Nicolas Wirtz"

  • - Nicolas Wirtz's research primarily focuses on the effects and applications of Whole-Body Electromyostimulation (WB-EMS) in various training contexts, highlighting its potential benefits for individuals with mobility issues or those seeking time-efficient training solutions.
  • - Recent studies by Wirtz provide evidence that WB-EMS is effective in reducing pain and improving strength in individuals with chronic nonspecific low back pain, showing comparable results to conventional back-strengthening exercises.
  • - Wirtz's work also explores the physiological impacts of WB-EMS on athletic performance, revealing that while WB-EMS can enhance strength and power, it may not significantly affect endurance performance in specific training scenarios.
