X; mean, SD; standard deviation, LSD; least significant differences. The different upper case letters indicate significant differences between groups (Bonferroni, P < .05). The different lower case letters indicate significant differences between sites of strain gauges (Bonferroni, P < .05). ^*P is significant at 5% level of significance.
