Magnetic muscle stimulation produces fatigue without effort.
IN DISEASE AND OLD AGE, muscle function decreases, and greater impairments in performance are associated with increased mortality (6, 9, 10). Although muscle strength and endurance can be assessed with voluntary exercise, measurements can be confounded by changes in the way the muscle is driven by the nervous system and by cardiorespiratory limitations. A means to measure muscle strength and en...
متن کاملEffects of low-frequency electrical stimulation on cumulative fatigue and muscle tone of the erector spinae
[Purpose] The aim of this study was to determine the effect of low-frequency electrical stimulation on fatigue recovery of the erector spinae with cumulative fatigue induced by repeated lifting and lowering work. [Subjects] Thirty-two healthy men volunteered to participate in this study and they were randomly divided into three groups: a MC group of 12 persons who underwent microcurrent, a TENS...
متن کاملAssessment of low-frequency fatigue with two methods of electrical stimulation.
The aim of this study was to compare the use of transcutaneous vs. motor nerve stimulation in the evaluation of low-frequency fatigue. Nine female and eleven male subjects, all physically active, performed a 30-min downhill run on a motorized treadmill. Knee extensor muscle contractile characteristics were measured before, immediately after (Post), and 30 min after the fatiguing exercise (Post3...
متن کاملSurface-distributed low-frequency asynchronous stimulation delays fatigue of stimulated muscles.
INTRODUCTION One important reason why functional electrical stimulation (FES) has not gained widespread clinical use is the limitation imposed by rapid muscle fatigue due to non-physiological activation of the stimulated muscles. We aimed to show that asynchronous low-pulse-rate (LPR) electrical stimulation applied by multipad surface electrodes greatly postpones the occurrence of muscle fatigu...
متن کاملForce output during fatigue with progressively increasing stimulation frequency.
There is currently a controversy over whether stimulation frequencies should increase or decrease to optimize force output over time. This study compared changes in thenar muscle force and M-wave amplitude during progressively increasing (20-40 Hz), decreasing (40-20 Hz) and constant (20 Hz) frequency stimulation of the median nerve continuously for 3 min. Twenty-three individuals participated ...
