This study compares the magnitude and speed of restoring fatigue-impaired postural stability following passive and active recovery modalities, including diaphragmatic breathing, trunk stability exercises, and foam rolling, among sedentary employees. Eighteen sedentary adults (aged 36.2 ± 8.1 years) volunteered for this study. They performed a modified Abt's fatigue protocol involving 8 exercises specifically targeting their core muscles. Immediately following the fatiguing intervention, they underwent three active recovery modalities (diaphragmatic breathing, trunk stability, and foam rolling exercises), and one passive recovery (lying on the bed), each separated by a week. Postural stability and muscle activity were assessed pre-fatigue, post-fatigue, immediately, and 15 min post-recovery. After core muscle fatigue, center of pressure (CoP) velocity significantly increased in both stable and unstable conditions. Restoration of CoP velocity was most effective following trunk stability exercises, followed by diaphragmatic breathing, foam rolling, and passive recovery. Similarly, CoP displacement increased post-fatigue, with trunk stability exercises and diaphragmatic breathing showing the greatest effectiveness in restoring its values to pre-fatigue levels. After 15 minutes of recovery, no significant changes were observed in CoP velocity and displacement in either condition. These findings suggest that trunk stability exercises and diaphragmatic breathing rapidly restore postural stability after fatigue in sedentary adults, outperforming foam rolling and passive recovery.Trial registration: IRCT20221126056606N1.

本研究比较了久坐不动的员工在采用被动和主动恢复方式（包括膈肌呼吸、躯干稳定性训练和泡沫轴放松）后，恢复因疲劳而受损的姿势稳定性的程度和速度。18名久坐不动的成年人（年龄36.2±8.1岁）自愿参与本研究。他们进行了一项改良的阿特疲劳方案，其中包括8项专门针对其核心肌肉的练习。在疲劳干预后，他们立即进行了三种主动恢复方式（膈肌呼吸、躯干稳定性训练和泡沫轴放松练习），以及一种被动恢复方式（躺在床上），每种方式之间间隔一周。在疲劳前、疲劳后、恢复后立即以及恢复后15分钟评估姿势稳定性和肌肉活动。核心肌肉疲劳后，在稳定和不稳定条件下，压力中心（CoP）速度均显著增加。躯干稳定性训练后，CoP速度的恢复最为有效，其次是膈肌呼吸、泡沫轴放松和被动恢复。同样，疲劳后CoP位移增加，躯干稳定性训练和膈肌呼吸在将其值恢复到疲劳前水平方面显示出最大效果。恢复15分钟后，在任何一种条件下，CoP速度和位移均未观察到显著变化。这些发现表明，躯干稳定性训练和膈肌呼吸能在久坐成年人疲劳后迅速恢复姿势稳定性，优于泡沫轴放松和被动恢复。试验注册：IRCT20221126056606N1。注册日期：2022年12月25日。
