As with the males, this decrease in activity was probably due to the despin accelerations. The male and female activity patterns are similar in that activity greatly increases from the first to the second minute of microgravity and then maintains that level or decreases slightly. Interestingly, neither males nor females show differences between the pad and launch groups, although the gravitational level is changing drastically during the launch phase. The only statistical difference between the male and female data occurs for the horizontally oriented group while on the pad.

The fourth minute of microgravity data lasts only 45 seconds, due to re-entry into Earth s atmosphere. Thirty microgravity parabolas were performed during the flight. For each of the microgravity segments, the activity level between the horizontal and vertical groups was significantly different. However, the activity level between these two position groups was not different during level flight before or after the parabolas.
