“…The knee joint musculature is considered important in producing large flexion and extension moments while recovering from a slip [11]. Fatigue of the knee extensors and hip flexor muscles is associated with decreases in stabilization time [12]. Additionally, LMF of the quadriceps adversely affects knee proprioception [13].…”

This study examines how lower extremity fatigue of the quadriceps alters gait variables related to slip propensity. Sixteen healthy young adults were recruited to walk across vinyl floor surfaces in states of fatigue and no fatigue. Kinematic and kinetic data were collected using a three-dimensional motion analysis system and force plates. The results indicated a significant increase in both the heel contact velocity and required coefficient of friction and a decrease in the transitional acceleration of the whole body center of mass and peak knee joint moment in the fatigue trials. Thus, suggesting that slip propensity could increase with fatigue. Additionally, there was increased knee flexion and reduced ankle dorsiflexion at the heel contact phase of the gait cycle during fatigue trials. These findings provide new insights into the biomechanical relationship between localized muscle fatigue and gait parameters associated with slip propensity. The present study concluded that localized muscle fatigue affects gait parameters and hence can be considered as a potential risk factor for slipinduced falls.

“…In addition, Miller and Bird 35 observed that fatigue of the lower limb proximal muscles exerted a stronger impact on balance as compared to fatigue of the distal muscles. Additionally, the results of the present study revealed a strong effect of fatigue on the ability to maintain static balance.…”

“…A previous study investigated muscle fatigue affecting the ankle, knee, and hip joints as well as the abdominal muscles on the control of dynamic balance 35 , and the results showed that fatigue of the knee and hip joint muscles was associated with less balance reduction compared to other groups of muscles. In addition, Miller and Bird 35 observed that fatigue of the lower limb proximal muscles exerted a stronger impact on balance as compared to fatigue of the distal muscles.…”

| Objective:This study sought to analyze the effect of muscle fatigue induced by active isotonic resistance training at a moderate intensity by measuring the knee extension motion during the stabilometric response in a single-leg stance among healthy university students who perform resistance training on a regular basis. Method: Eleven healthy university students were subjected to a one-repetition maximum (1RM) test. In addition, stabilometric assessment was performed before and after the intervention and consisted of a muscle fatiguing protocol, in which knee extension was selected as the fatiguing task. The Shapiro-Wilk test was used to investigate the normality of the data, and the Wilcoxon test was used to compare the stabilometric parameters before and after induction of muscle fatigue, at a significance level of p≤0.05. Descriptive statistics were used in the analysis of the volunteers' age, height, body mass, and body mass index (BMI). Results: The sample population was 23.1±2.7 years of age, averaged 1.79.2±0.07 m in height and 75.6±8.0 Kg in weight, and had a BMI of 23.27±3.71 Kg.m -2 . The volunteers performed exercises 3.36±1.12 days/week and achieved a load of 124.54±22.07 Kg on 1RM and 74.72±13.24 Kg on 60% 1RM. The center of pressure (CoP) oscillation on the mediolateral plane before and after fatigue induction was 2.89±0.89 mm and 4.09±0.59 mm, respectively, while the corresponding values on the anteroposterior plane were 2.5±2.2 mm and 4.09±2.26 mm, respectively. The CoP oscillation amplitude on the anteroposterior and mediolateral planes exhibited a significant difference before and after fatigue induction (p=0.04 and p=0.05, respectively). Conclusions: The present study showed that muscle fatigue affects postural control, particularly with the mediolateral and anteroposterior CoP excursion.Keywords: rehabilitation; muscle fatigue; exercise; postural balance.

“…Hip abductor muscle fatigue has an effect on hip joint position sense and gait control within healthy elderly people [16]. Local muscle fatigue leads to poor postural control, and furthermore, fatigue of the proximal muscles produce an even greater negative impact on balance ability compared to fatigue of the distal muscles [17].…”

Objective: Hip abductors play a role in providing stability and movement to the lower limbs. The purpose of this study was to examine the effects of hip abductor fatigue on static balance and gait in the general population. Design: One group pre-test post-test design. Methods: Thirteen university students in their twenties volunteered for the study and had underwent a functional assessment. To induce fatigue, the subjects were instructed to raise their dominant lower extremity up against a load of 50% of 1 repetition maximum while producing hip abduction in a side-lying position. Subjects were instructed to maintain an abduction speed of 30 repetitions per minute to induce fatigue. Muscle fatigue was considered to be established when subjects were unable to perform hip abduction three consecutive times along with the metronome. A post-test of balance and gait was performed immediately in order to prevent fatigue recovery. The center of pressure (COP) distance area was measured using the Zebris FDM-S Multifunction Force measuring plate. Gait performance was analyzed using the GAITRite. Results: The COP distance was increased after fatigue was induced. There was a significant increase in the standard deviation of the medio-lateral and antero-posteror distance (p<0.05). Although there was no significant difference in gait parameters, there was a significant decrease in single support time after fatigue was induced (p<0.05). Conclusions:There was an increase in static balance instability and a significant decrease in single support time during gait due to hip abductor muscle fatigue.
