Lateral VIMT
Similar to VLMT, there was moderate evidence in favor of pre-training MT, but not group, as a predictor of the change in lateral VIMT (BF10 = 3.3, Table 6). There was weak evidence in favor of the null model over the group model (BF10 = 0.32, Table 6). Changes in lateral VIMT were similar among groups (Fig. 1B), and change in body mass was not favored over the null model as a predictor of change in lateral VIMT (BF10 = 0.43, R2 = 0.0).
Anterior VIMT
There was weak evidence in favor of pre-training MT, but not group, as a predictor of the change in anterior VIMT (BF10 = 1.6, Table 6). There was weak evidence in favor of the null model over the group model (BF10 = 0.33, Table 6). Changes in anterior VIMT were similar among groups (Fig. 1C), and change in body mass was not favored over the null model as a predictor of change in anterior VIMT (BF10 = 0.51, R2 = 0.04).
RFMT
There was weak evidence in favor of pre-training MT, but not group, as a predictor of the change in anterior VIMT (BF10 = 1.5, Table 6). There was weak evidence in favor of the null model over the group model (BF10 = 0.77, Table 6). Changes in RFMT were similar among groups (Fig. 1D), and change in body mass was not favored over the null model as a predictor of change in RFMT (BF10 = 0.63, R2 = 0.08).
Triceps MT
Evidence weakly favored the null model over all other models (Table 6). Specifically for group, there was weak evidence in favor of the null model over the group model (BF10 = 0.52, Table 6). Changes in triceps MT were similar among groups (Fig. 1E), and change in body mass was not favored over the null model as a predictor of change in triceps MT (BF10 = 0.43, R2 = 0.0).
Biceps MT
Evidence weakly favored the null model over all other models (Table 6). Specifically for group, there was weak evidence in favor of the null model over the group model (BF10 = 0.35, Table 6). Changes in biceps MT were similar among groups (Fig. 1F) and change in body mass was only weakly favored over the null model as a predictor of change in biceps MT (BF10 = 1.4, R2 = 0.24).
