Objective: The purpose of this study was to assess and compare the sensorimotor responses after 16 weeks of CF, LM and TRAD trainings.
Methods: A total of one hundred and seven sedentary participants (81 men, 26 women, age 30.5 ± 5.7 years, weight 78.9 ± 11.1 kg, height 174.9 cm, fat mass 25.4 ± 5.3%) were assigned randomly into 3 groups CF (n = 34), LM (n = 33) and TRAD (n = 40), they followed the training allocated at the rate of 5 sessions/week for 16 weeks. On three occasions: before (T0), after eight (T1) and sixteen weeks (T2) of training, participants underwent different tests of sensorimotor measures; coordination (Extremity Motor Coordination Test), accuracy (Motor Accuracy Test), agility (Illinois Agility Test) and balance (Y Balance Test).
Results: Coordination improved only in the LM group for upper (T0-T1: p < .001, d = 0.09-0.13; T1-T2: p < .001, d = 0.16-0.18) and lower limbs coordination (T0-T1: p < .001, d = 0.16-0.25; T1-T2: p < .001, d = 0.24-0.26). Agility test showed improvements for LM (T0-T1: p < .001, d = 0.55; T1-T2: p < .001, d = 0.87) and CF (T0-T1: p = .002, d = 0.20; T1-T2: p < .001, d = 0.40) and no difference for TRAD. For balance, results showed improvements in lower limbs for CF (T0-T1: p < .001, d = 0.08-0.14, T1-T2: p < .001, d = 0.05-0.23) and TRAD (T0-T1: p ≤ .003, d = 0.05-0.08, T1-T2: p < .001, d = 0.08-0.13) and at T2 for LM (p = 0.04, d = 0.06-0.2), for the upper limbs, results showed improvements for CF (T0-T1: p < .001, d = 0.04-0.09; T1-T2: p < .001, d = 0.15-0.28), at T2 for TRAD (p = .01-.03, d = 0.03-0.10) and no difference for LM. For motor accuracy, results did not show any difference.
Conclusions: CF and LM trainings helps develop agility; however, CF and TRAD are more oriented to balance while LM are to coordination improvement, all three trainings have no effect on motor accuracy.
