Issue Date: | 2022 | Publisher: | ELSEVIER SCI LTD | Source: | JOURNAL OF BIOMECHANICS, 133 (Art N° 110890) | Abstract: | This study aimed to investigate if the impairing in postural control, induced by ankle fatiguing exercise, remains after 24/48 h in young adults. Center of Pressure (CoP) was assessed in 16 participants (23 & PLUSMN; 3 years old) before, immediately after an ankle fatigability induction protocol (FI) and after 24 or 48 h of recovery using two 60-s trials with eyes open (EO) and closed (EC). The FI consisted of performing the ankle plantar flexion and dorsiflexion movement repeatedly (0.5 Hz). Ankle muscle fatigability increased CoP anterior-posterior (AP - p < 0.02) and medial-lateral (ML - p < 0.009) root mean square (RMS), and AP (p < 0.01) mean velocity immediately after compared to before FI. These effects remained after 24/48 h of recovery: higher CoP AP (p < 0.03) and ML (p < 0.009) RMS. No significant effects for detrend fluctuation analysis and entropy analysis among periods of postural evaluations was found. Fatigue*visual condition interaction revealed an increased AP median frequency (p < 0.001) during EC compared to EO only immediately after FI. Young adults' body sway remains impaired until 48 h, but not the postural control adaptability and complexity. Visual information may not attenuate the late deleterious ankle muscle fatigability effects. Individuals should be cautious during balance tasks and exercise after fatiguing exercise in the next 24/48 h, therefore avoiding unbalances and falls. | Notes: | Penedo, T (corresponding author), Sao Paulo State Univ UNESP, Sch Sci, Dept Phys Educ, Human Movement Res Lab, Campus Bauru,Ave Eng Luiz Edmundo Carrijo Coube 14, BR-17033360 Bauru, SP, Brazil. penedoedfis@gmail.com; nicolas.vuillerme@univ-grenoble-alpes.fr; felipebsantinelli@icloud.com; gaa_moretto@hotmail.com; elisa_bes@hotmail.com; juliapilon@hotmail.com; kalvafilho@yahoo.com.br; fabio.barbieri@unesp.br |
