Changes in Physical Fitness After 12 Weeks of Structured Concurrent Exercise Training, High Intensity Interval Training, or Whole-Body Electromyostimulation Training in Sedentary Middle-Aged Adults: A Randomized Controlled Trial

Conclusion Our findings suggest that a 12-week structured high intensity interval training program adding whole-body electromyostimulation did not significantly improve overall physical fitness compared with both a high intensity interval training program without whole-body electromyostimulation and a traditional concurrent training program in sedentary middle-aged adults. However, clinically relevant improvements were observed in the WB-EMS group in some physical fitness variables. Therefore, further studies with greater sample size and longer duration are needed to elucidate whether the combination of voluntary exercise and whole-body electromyostimulation is effective to increase both cardiorespiratory fitness and muscular strength. Ethics Statement All participants provided a written informed consent to participate in the current study (http://www.clinicaltrials.gov, ID:NCT03334357) (Amaro-Gahete et al., 2018c) which complied with the requirements of the last revised Declaration of Helsinki and was approved by the Human Research Ethics Committee of the “Junta de Andalucía” (0838-N-2017). Figure 1 shows the flow of participants throughout the study. Author Contributions FA-G, AD-l-O, ÁG, JR, and MC conceived and designed the study. FA-G, AD-l-O, LJ-F, and MD-M performed the tests and the intervention training. FA-G and JR performed the statistical analysis. FA-G drafted the manuscript. ÁG, JR, and MC revised the manuscript.
