The paths of young, middle-aged and old Drosophila melanogaster flies, kept at various gravity levels (1-5 g) throughout life, have been recorded in a cross-sectional study. Aging flies exhibit more sinuous paths and do not move as far away from their release point as younger ones. These age-related changes in the patterns of movement are expressed at younger ages in flies submitted to hypergravity. As for the climbing activity experiment, the patterns of movement do not clearly vary with the gravity level at young age. Results are discussed in relation to the hypothesis of increased aging rate in hypergravity.
在一项横断面研究中，记录了在整个生命周期中处于不同重力水平（1-5克）下的年轻、中年和老年黑腹果蝇的运动轨迹。衰老的果蝇表现出更弯曲的轨迹，并且不像年轻果蝇那样远离释放点移动。在经受超重力的果蝇中，这些与年龄相关的运动模式变化在较年轻时就会表现出来。至于攀爬活动实验，在年轻时运动模式并没有随重力水平而明显变化。结合超重力下衰老速率增加的假设对结果进行了讨论。
