Abstract:  Objective: To analyze the effects of whole body electrostimulation (WB-EMS) with body weight training on functional fitness and body composition of older men. Methods: Twenty physically inactive older men were randomized into: Control group (control), performed the body weight exercise training wearing electrostimulation clothing, but without receiving electrical current stimuli (n = 10), and body weight associated with whole body electrostimulation group (BW+WB-EMS), performed the body weight exercise training wearing electrostimulation clothing plus whole body electrostimulation (n = 10). The training sessions were performed twice a week for 6 weeks and included eight exercises using body weight, performed in two sets of eight repetitions. Physical function was assessed using a battery composed of seven tests, six derived from the Senior fitness test and a handgrip strength test. We also measured the muscle thickness (MT) of the biceps and triceps brachii and vastus lateralis. Results: The BW+WB-EMS group presented increased (p &lt; 0.05) performance in the 30-s chair stand test (10.2 ± 3.3 vs. 13.8 ± 5.0 reps), arm curl (16.6 ± 3.9 vs. 19.9 ± 6.1 reps), 6-min walk test (402 ± 96 vs. 500 ± 104 m), and handgrip strength test (30 ± 11 vs. 32 ± 11 kgf). The BW+WB-EMS group also presented increased MT (p &lt; 0.05) in the biceps brachii (17.7 ± 3.0 vs. 21.4 ± 3.4 mm), triceps brachial (14.7 ± 3.6 vs. 17.5 ± 4.1 mm), and vastus lateralis muscles (15.1 ± 2.6 vs. 18.6 ± 4.3 mm). Moderate correlations were found in arm curl (p = 0.011, r = 0.552) but not handgrip strength (p = 0.053, r = 0.439) with changes in the biceps MT. Moderate changes in the 6-min walk distance were significantly correlated with changes in vastus lateralis MT (p = 0.036, r = 0.471). There was a moderate correlation between the changes in the 30-s chair stand test (p = 0.006, r = 0.589) and changes in the vastus lateralis MT. Furthermore, although a moderate correlation (r = 0.438) was found between triceps MT and handgrip strength no significant difference (p = 0.053) was reported. Additionally, there were no statistical differences in any parameters for the control group. Conclusion: WB-EMS with body weight training increased functional fitness and MT in physically inactive older men.

 #1 This was a careless mistake. The results are from multiple independent migration assays. I have added the representative images of 2 independent migration assays. The results are correct. ![file] , 
 #3 Dear Dr. Soichiro Yamamura, The representative images you have uploaded are still from the same assay. Only cropped to have less overlap. ![file] Whereas you maintain that the results are correct, surely you have to understand that the frequency with which careless mistakes seem to occur with respect to these data may start to undermine the reader s confidence in the findings. , 
 #4 Images of ACHN cells were misplaced in a 786-O folder so the duplication occurred. The following are representative images of three independent migration assays. ![file] , 
 A correction is now on-line. https: www.cellphysiolbiochem.com Articles 000312 ----------------------------------------------------- Erratum In the original article by Imai-Sumida, et al., entitled u201cGenistein Represses HOTAIR Chromatin Remodeling Pathways to Suppress Kidney Canceru201d [Cell Physiol Biochem 2020;54(1):53-70, DOI: 10.33594 000000205], a mistake has been made during the compilation of the data for the representative images of migrated cells in Figure 1C. The authors confirm that all of the results and conclusions of the article remain unchanged, as well as the figure legend. The authors sincerely apologize for this mistake. Additionally, there has been a change in authorship; Rajvir Dahiya is no longer co-author. All authors agree with this change. The corrected title section of the paper and the corrected Fig. 1 are displayed below. ![file] ,
