A separate effect analysis to determine the association between injury and both phases and range of scapula upward rotation was also explored in both junior and Paralympic groups,
with each group classified into injured and non-injured subgroups (Table 1).
The most surprising result was that, in the junior group, a 73.1% (or 8°) difference was found between the injured and non-injured subgroups in Phase I
As there was no difference at 45°, this result most likely reflected the resting position of the scapula. Furthermore,
arge percentage differences were found between injured and non-injured junior swimmers in the remaining phases,
resulting in 42% more range in the non-injured swimmers. For the Paralympic group,
the greatest difference between injured and non-injured swimmers was 43.6% (or 3.3°) in Phase 1.
For other phases, the differences between the injured and non-injured groups were probably too small for clinical relevance.
