Compression relaxation stress at 0 sec, and percent loss at 10, 30 and 120 sec after holding strain at 2, 6 and 10%. Results were similar for the intermediate strain levels. See Figure 2 for locations and abbreviations.

^*Dorsal horizontal samples loaded at 1%/sec (DH) showed a greater drop in relaxation stress compared to those loaded at 0.1%/sec (DH (a) and DH (p)) (p<0.05, repeated measures ANOVA).

^†Horizontal samples (DH and VH) showed a greater drop in relaxation stress compared to the anterior vertical samples (AV) (p<0.03, repeated measures ANOVA) for all strain levels (except 2% dorsal horizontal)
