Separate studies have demonstrated that vibration and fatigue of ankle muscles alter postural control. The purpose of the present experiment was to investigate the effect of ankle muscle vibration on the regulation of postural sway in bipedal stance following ankle muscle fatigue. Center of foot pressure displacements were recorded using a force platform. Results showed a similar increase in po...

PURPOSE A lack of fatigue-related muscle contractile property changes at time of perceived physical exhaustion and greater central than peripheral fatigue detected by twitch interpolation technique have recently been reported in cancer survivors with fatigue symptoms. Based on these observations, it was hypothesized that compared to healthy people, myoelectrical manifestation of fatigue in the ...

Localized muscle fatigue and perception of fatigue/discomfort in the lower legs induced by a 5 hour standing work task were evaluated for 3 different work surfaces (linoleum tiles on concrete floor, rubber mat, sole insert) in young adults and older individuals. Muscle fatigue was quantified by the muscle twitch force (MTF) magnitude and subjective ratings. The results indicate that the work ta...

135 General discussion In the general introduction, it was stated that occupational work often involves prolonged sustained low-force repetitive activities and a number of recent trends may further increase the prevalence of this type of work. Although force levels are relatively low, muscle fatigue or physiological signs of localized muscle fatigue may develop during low-intensity work. Locali...

Respiratory muscle fatigue develops during exhaustive exercise and can limit exercise performance. Respiratory muscle training, in turn, can increase exercise performance. We investigated whether respiratory muscle endurance training (RMT) reduces exercise-induced inspiratory and expiratory muscle fatigue. Twenty-one healthy, male volunteers performed twenty 30-min sessions of either normocapni...

objectives: skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. the main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  methods: fifteen sub...

AIM The aim of this study was to identify adaptations in muscle activity distribution to spinal tissue creep in presence of muscle fatigue. METHODS Twenty-three healthy participants performed a fatigue task before and after 30 minutes of passive spinal tissue deformation in flexion. Right and left erector spinae activity was recorded using large-arrays surface electromyography (EMG). To chara...

[Purpose] The purpose of this study was to identify the effects of kinesiology taping on repositioning error of the knee joint after quadriceps muscle fatigue. [Subjects] Thirty healthy adults with no orthopaedic or neurological problems participated in this study. [Methods] The repositioning error of the knee joint was measured using a digital goniometer when the subjects extended their domina...

Women generally exhibit greater fatigue resistance than men, due in part to differences in muscle mass. Less muscle mass in women results in decreased oxygen demand and increased oxygen delivery at the same relative workload compared to men and yields greater endurance. The purpose of this study was to examine sex differences in muscle fatigue between male and female athletes matched for muscle...
