Abstract
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). Afterwards, on 20th May 2021, a corrigendum was published (Evangelista et al., 2021). 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).
Highlights
Lean Body MassThe 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
INCONSISTENT DATA PATTERN Lean Body MassTable 2, presented on the first version of the article, showed inconsistent body composition data for both groups at Pre and Post moments (See Figure 1)
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)
Summary
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 According to their body fat data (31.8 ± 12.2%), the fat mass should be 22.2 ± 1.4 kg. Even in the corrigendum version, it is still lacking 2.0 and 0.4 kg in the Control and BW+WB-EMS group, respectively (see Supplementary Material)
