Mean (range) length changes in the left forelimb of four horses during the stance phase of trot (3.5 m s-1), right lead canter (6 m s-1 and 8 m s-1) and right lead gallop (12 m s-1)
| Speed (m s-1) | ||||
|---|---|---|---|---|
| 3.5 | 6 | 8 | 12 | |
| Proximal length change (mm) | 12 (6-14) | 6 (4-9) | 11 (3-16) | 12 (9-15) |
| Distal length change (mm) | 80 (67-86) | 86 (68-96) | 96 (80-109) | 127 (106-128) |
| Ratio of mean length change Distal:Proximal | 7.9 | 15.2 | 12.7 | 10.0 |
Proximal length change is that which occurs between the proximal scapula and the elbow joint; distal length change is that which occurs between the elbow and the hoof (N=4).
