Chronic centrifugation of 85- to 92-day-old Beagles at 2.0 X g and 2.6 X g for 26 weeks during the time of active skeletal growth caused skeletal abnormalities in the radius and the ulna of ten of 11 dogs. The pattern of change mimicked that found in naturally occurring and experimentally induced premature distal ulnar physeal closure or delayed growth at this physis. Minimal changes in bone density were detected by sensitive photon absorptiometric techniques. Skeletal abnormalities also were found in five of the six cage-control dogs, although the run-control dogs were radiographically normal.
在85至92日龄的比格犬骨骼快速生长期间，以2.0×g和2.6×g的加速度进行26周的慢性离心处理，导致11只犬中的10只桡骨和尺骨出现骨骼异常。变化模式与自然发生和实验诱导的尺骨远端骺板过早闭合或该骺板生长延迟所发现的模式相似。通过敏感的光子吸收测量技术检测到骨密度的微小变化。在6只笼养对照犬中也发现了骨骼异常，尽管跑步对照犬的X线片显示正常。
