Table 3.
Morphological data summary of GM from TS, Ctrl and Vib at different timepoints including muscle mass (Mm), optimal length (Lo), physiological cross-sectional area (pCSA) and fiber cross-sectional area (FCSA). a,b Ctrl larger than TS, p<0.01 and p<0.001 respectively; c,d Vib larger than TS, p<0.05 and p<0.01 respectively; e Day21 larger than TS, p<0.001; f TS larger than Day 14, p<0.05; g Day 14 larger than TS, p<0.001; h Ctrl larger than Vib, p<0.01; main effects detected from Two-way ANOVA. No significant interaction detected.
