Objective:
This study aimed to evaluate the muscle activation responses of the deltoid (anterior (AD) and posterior (PD)) and brachioradialis (BRD) muscles in an adapted shuttle run test for Parabadminton (PBd).
Methods:
Thirteen PBd athletes (WH1 = 4; WH2 = 9), performed an adapted shuttle run test under four experimental conditions (moderate (Mod) and intense (Int) effort; with (W) and without (Wout) racket use). The performance in the test was analyzed (cycles: the result of the adapted shuttle run test; frequency: Hz; and speed [m/s]). Non-normal data (Shapiro-Wilk) were analyzed using Friedman's ANOVA and Dunn's post-hoc test, with significance set at P < 0.05.
Results:
The difference in muscle activation of the AD was significant between Mod-W vs. Int-W (69.11% vs. 97.96; P = 0.0357), and Int-W vs. Mod-Wout (97.96% vs. 67.23; P = 0.0480). For the PD there were differences between Mod-W vs. Int-Wout (154.40% vs. 250.35; P = 0.0143), and Mod-Wout vs. Int-Wout (183.85% vs. 250.35; P = 0.0029). For the BRD there were significant differences between Mod-W vs. Int-W (90.04% vs. 121.72; P = 0.0143), Mod-W vs. Int-Wout (91.12% vs. 123.00; P = 0.0375), Int-W vs. Mod-Wout (121.72% vs. 90.04; P = 0.0143), and between Mod-Wout vs. Int-Wout (90.04% vs. 123.00; P = 0.0375).
Conclusion:
This study concludes that effort intensity is crucial for muscle activation of AD, PD, and BRD in PBd athletes, with greater recruitment observed in intense effort.
