Influences of parabolic flight on activity of wrist and trunk activities.

<p>(A) Schematic representation of the parabolic flight profile. (B) The gravity levels that occurred during the parabolic flights and the blocks used for data collection (I-V). Block I: prior to parabola; block II: during hypergravity; block III: during hypogravity; block IV: during hypergravity; block V: prior after parabola. The duration of each block was 15 s. (C) The placements of Actiheart and Actiwatch on a human subject. (D) Trunk activity recorded by the Actiheart. The data are presented as the averages of 195 parabolas completed by seven subjects. (E) Wrist activity recorded by Actiwatch. Data are averages from the mean values of eight subjects. Statistical significance was determined with one-way repeated-measures ANOVA with Fisher’s least significance difference (LSD) post hoc test. The data are means ± SEs. The <i>P</i> values are shown to indicate significant differences.
