“…This speed modulation appears to be caused by a larger magnitude of the negative horizontal (braking) force in the last stride before crossing the obstacle. Locomotion in complex environments requires adaptive ability from the locomotor system [7] and more attention [18], especially when crossing an obstacle [19,20]. Reduced speed allows more exploration and collection of relevant information and more time for planning the action [21].…”

“…This may be a direct consequence of the reduction in step duration. On the other hand participants may have tried to perform the task as quickly as possible [31] and the increase in speed could be a risky strategy that decreases the reaction and processing time available to plan crossing the obstacle [19][20][21], which may be compensated for by larger step width [32]. Previous authors have suggested that muscle fatigue increases fall risk [2,3], however this was based on an increased heel contact velocity, which mainly relates to the risk of slipping.…”

Effect of muscle fatigue and physical activity level in motor control of the gait of young adults

et al. 2013

The aim of this study was to analyze the effect of muscle fatigue in active and inactive young adults on the kinematic and kinetic parameters of normal gait and obstacle crossing. Twenty male subjects were divided into active (10) and inactive (10), based on self-reported physical activity. Participants performed three trials of two tasks (normal gait and obstacle crossing) before and after a fatigue protocol, consisting of repeated sit-to-stand transfers until the instructed pace could no longer be maintained. MANOVAs were used to compare dependent variables with the following factors: physical activity level, fatigue and task. The endurance time in the fatigue protocol was lower for the inactive group. Changes of gait parameters with fatigue, among which increased step width and increased stride speed were the most consistent, were independent of task and physical activity level. These findings indicate that the kinematic and kinetic parameters of gait are affected by muscle fatigue irrespective of the physical activity level of the subjects and type of gait. Inactive individuals used a slightly different strategy than active individuals when crossing an obstacle, independently of muscle fatigue.

“…The results of this study [21], with reductions in gait speed and stride length in young adults only, suggest that young adults use a more conservative strategy [29,30] to deal with fatigue. Also other studies with young adult participants only showed indications of a more conservative strategy, although heel contact velocity increased with fatigue, which would increase slip risk [31].…”

Seven studies were selected for this systematic review, two of which reported on the same data set. Several spatiotemporal parameters were reported to change with fatigue, but the few variables studied in multiple studies, gait speed and stride or step length and stride time, were affected only in single studies. Fatigue appears to modulate spatiotemporal gait parameters, but the effects of fatigue appear to be dependent on the muscles that were fatigued, and age that appears to be a moderator of the effects of fatigue on gait.
