Fig. 1. Mean torque during plantarflexion motor control tests performed at 10 and 50% maximal voluntary contraction (MVC) on test days pre-flight (L-30 and L-12), in-flight (F7/8 and F13/14) and post-flight (R+0, R+2, R+8, and R+15). The filled bar on the x-axis indicates flight days. Values are means ± S.E.M.; N=4 at each time point. Blue symbols indicate a significant difference between pre- and in-flight values. Green symbols indicate a significant difference between pre- and post-flight values. Orange symbols indicate a significant difference between in- and post-flight values. For 10% MVC, post-flight was elevated over pre-flight (P=0.03) and in-flight (P=0.009) values. For 50% MVC, pre-flight values were lower than in-flight (P=0.02) and post-flight (P=0.002) values. The P levels for the ANOVA main effects are shown.
