There was a significant group × time interaction in MSNA frequency and incidence ( P = 0.022 and 0.023, respectively; Figure 2 ) with a decreasing trend in Exercise group (33.5 ± 11.8 [95%CI, 27.6–39.2] to 28.1 ± 12.5 [95%CI, 22.1–34.1] bursts/min, P = 0.111; 54.4 ± 19.1 [95%CI, 44.8–64.0] to 44.9 ± 21.5 [95%CI, 34.5–55.3] bursts/100 heart rate [100HR], P = 0.054), but an increasing trend in Stretching group (30.6 ± 10.6 [95%CI, 24.1–37.1] to 36.0 ± 10.4 [95%CI, 29.4–42.6] bursts/min, P = 0.081; 50.2 ± 18.1 [95%CI, 39.6–60.9] to 57.7 ± 18.3 [95%CI, 46.2–69.2] bursts/100HR, P = 0.165) after 12 weeks.
