Table 2. Baseline (week 1) and post-intervention (week 8) values for peak inspiratory power at different percentages of load, following inspiratory muscle training (IMT, n = 11) and Otago exercises program (OEP, n = 14).

Data are reported as mean ± standard deviation, MAXPP = maximal peak power, MIP = maximal inspiratory pressure. W = Watts. NS = non-significant.

* Significantly different from baseline (P ≤ 0.05)

** significantly different from baseline (P ≤ 0.01). NS = not significant.
