The anthropometric data of the participants are reported in Table 1. There were no significant differences between the two groups (p \(>\) 0.05). According to IDF [2], participants with increase in WC values have more probability to develop MetS. The acute effects of WBVE on the ROM of the right and left knees in the first session are shown in Table 2. No significant changes in ROM were observed in either of the groups (CG and TG) or in the comparison between them. Although no significant differences (p \(>\) 0.05) were detected, the %AROM of the right knee of the participants in the CG decreased slightly (85.65%), while that of the left knee increased slightly (107.21%). The %AROM of the right and left knees of the participants in the TG decreased slightly (98.09% and 98.10%, respectively). Table 3 shows the acute effects of WBVE on the ROM of the right and left knees in the last session. No significant changes were observed in either of groups (CG and TG) or in the comparison between CG and TG. Although no significant differences (p \(>\) 0.05) were detected, the %AROM of the right knee and of the left knee of the participants in the CG increased slightly (102.17% and 103.96%, respectively). \begin{table}

Table 2: Acute effects on range of the motion of right and left knees in the first session. The %AROM of the right knee of the participants of the TG decreased slightly (98.67%), and that of left knee increased (102.04%). The cumulative effects of WBVE on the ROM of both knees (i.e., value of ROM before the first session vs. the value before the last session) is reported in Table 4. Although no significant differences were detected in the TG or CG, an improvement of 7.5 and 13.51 degrees in ROM was observed in the TG on the left and right knee, respectively. Moreover, the %AROM of the right knee of the participants in the CG decreased slightly (98.53%), and that of the left knee increased (105.79%). The %AROM of the right and left knees of the participants in the TG increased importantly (114.29% and 107.44%, respectively). Using sEMG, Table 5 shows the response of the vastus lateralis muscle of both legs to the acute effect of WBVE in the first session, in %RMS. No significant effects were found (left or right legs) in TG or CG. The acute effects of WBVE on sEMG of the vastus lateralis muscles in the last session are shown in Table 6. Significant increases (p \(<\) 0.05) were observed on the %RMS of vastus lateralis muscles on both legs of the TG relative to the CG.
