ESULTS
The mean angle of knee-flexion measurements for pretest
and posttest active knee extensions are presented in the Table.
The repeated-measures ANOVA revealed a significant groupby-time
interaction (F6,168 = 9.93, P < .001). Tukey HSD post
hoc analyses revealed that significant increases in knee extension
were maintained in the experimental group at 1 and 3
minutes after cessation of the stretching protocol and then
gradually decreased over time. The control group's knee
extension was decreased from baseline at 3 minutes and
remained decreased throughout testing. The ANOVA also
revealed a significant main effect for time (F6,168 = 23.49, P <
.001); however, post hoc testing failed to determine when this
occurred. The dependent t test revealed a 5.90 increase in knee
extension (t29 = 8.46, P < .001) from the first AKE (129.20
12.20) to the sixth AKE (135.10 ± 12.30).
