Corrigendum: Effects of Whole Body Electrostimulation Associated With Body Weight Training on Functional Capacity and Body Composition in Inactive Older People

Commentary: Effects of Whole Body Electrostimulation Associated With Body Weight Training on Functional Capacity and Body Composition in Inactive Older People

“…The control group reported pre-values for body mass, body fat, and lean mass of 69.9 ± 11.7 kg, 31.8 ± 12.2%, and 24.7 ± 4.8 kg, respectively. FIGURE 1 | Indeed, the authors did not change "just the statistical signs" as they claimed, but all lean mass values as seen here: (A) Lean mass data presented on Table 2 of the first version of the article (Evangelista et al, 2021) (Evangelista et al, 2021) According to their body fat data (31.8 ± 12.2%), the fat mass should be 22.2 ± 1.4 kg. Subtracting the calculated fat mass from the body mass reported resulted in a lean mass of 47.7 ± 10.3 kg (i.e., 69.9-22.2 kg).…”

“…The final version of their manuscript was available on 1st April 2021 (See attached file). Afterwards, on 20th May 2021, a corrigendum was published (Evangelista et al, 2021). Even after the corrigendum, we found several inconsistencies.…”

“…The changes in vastus lateralis muscle thickness presented in Figures 4C,D of their article (Evangelista et al, 2021) have different range intervals for the same vastus lateralis muscle thickness. Figure 4C, presents individual increases of more than 100 mm (10 cm) in vastus lateralis muscle thickness, with one subject experiencing growth of nearly 400 mm (40 cm) while the same parameter in Figure 4D presents increase of no more than 10 mm!…”

“…Even after the corrigendum, we found several inconsistencies. Additionally, since the study was supported by the manufacturer of the electrostimulation equipment (Xbody © Brazil) (Evangelista et al, 2021) we think our critical comments deserve clarification. We believe this commentary will enrich the debate of such a relevant topic (i.e., exercise for the elderly population).…”

“…Investigations about the influence of different training methods on muscle hypertrophy and neuromuscular function in the elderly are quite relevant to general population health (Garcia-Hermoso et al, 2018). Thus, we read the recent manuscript by Evangelista et al (2021) about the effects of whole-body electrostimulation (WB-EMS) with body weight (BW) training on the functional fitness and body composition of older men. The final version of their manuscript was available on 1st April 2021 (See attached file).…”
