HABD strength demonstrated a significant
time-by-group interaction (P =
.041). A Bonferroni post hoc analysis revealed
that the hip group demonstrated
a significant increase in strength from
baseline (5.2 1.5) to 8 weeks (6.6 0.9)
(P = .001), while the quad group did not
(baseline, 5.7 2.2; 8 weeks, 6.2 1.8;
P = .9) (FIGURE 7). There was no significant
group-by-time interaction for HER strength (P = .06); however, there was a
main effect for time, indicating that HER
strength had increased over the 8-week
program for both groups (P = .004). A
Bonferroni post hoc analysis revealed
only a significant increase from baseline
(2.1 0.8) to the 8-week assessment (2.5
0.7) (P = .012). KE strength did not
demonstrate a significant time-by-group
interaction (P = .39), and no main effect
was found between groups (P = .6) or
across time (P = .12).
