Thus, there is conflicting evidence regarding sex-related differences in voluntary activation EMG and motor unit activation strategies as a result of fatiguing exercise. Like the neuromuscular responses during submaximal muscle contractions, there are also intensity-specific effects on MVIC torque and the neuromuscular responses following fatiguing workbouts. This article has been cited by other articles in PMC. Electromyography, Mechanomyography, Submaximal Fatigue, Motor Control, Isokinetic Introduction Time-dependent changes in electromyographic EMG and mechanomyographic MMG time and frequency domain parameters have been used to describe the patterns and time course of neuromuscular responses to fatigue and make inferences regarding the motor unit activation strategies that modulate torque production during fatiguing tasks[ 1 - 4 ]. The subjects visited the laboratory on 2 occasions separated by at least h and were instructed not to perform upper body exercise h prior to each visit. After 5-min of recovery, torque had partially recovered for the men, while torque had returned to pretest levels for the women. Abstract Objective: The sex-related differences in muscle fatigue have been associated with differences in muscle morphology, muscle size, muscle strength, muscle blood flow, metabolic substrate utilization i. J Musculoskelet Neuronal Interact. Cochrane N. Hill T. Contrary to these findings, however, Hunter et al[ 23 ] reported that there were no sex-related differences in voluntary activation, despite sex-related differences in MVIC torque following a fatiguing workbout. Thus, simultaneous assessments of timing and patterns of responses for the amplitude and frequency characteristics of EMG and MMG signals may provide insight regarding fatigue-related changes in motor unit activation strategies. Based on previous investigations[ 14 - 17 ], we hypothesized that men would experience greater reductions in MVIC torque and would require more time to recover following the fatiguing workbout. In addition, it has been demonstrated that the performance and neuromuscular responses to fatigue are intensity-specific[ 12 , 13 ]. Specifically, women can perform sustained muscle contractions for a longer duration of time and perform a greater number of intermittent muscle contractions than men at the same relative intensity[ 14 - 17 ]. The amplitude of the MMG signal, however, can provide information regarding motor unit recruitment and the frequency content is qualitatively related to the global firing rate of the activated motor units[ 8 - 10 ]. Eighteen men and women performed MVIC trials before pretest , after posttest , and 5-min after 5-min recovery performing 50 intermittent, submaximal isometric muscle contractions. It has been suggested that the mechanisms of muscle fatigue are sex-specific. Specifically, it has been suggested that the amplitude of the EMG signal reflects the level of muscle activation and the frequency content is associated with muscle fiber action potential conduction velocity[ 5 - 7 ]. For example, it has been hypothesized[ 14 , 19 ] that greater glycolytic rates in men may be associated with the buildup of metabolic byproducts and, consequently, increased activity of group III and IV nerve afferents which may adversely affect muscle activation. No previous investigations, however, have examined potential sex-specific MMG responses. Schmidt G. The study was approved by the University Institutional Review Board for Human Subjects and all subjects completed a health history questionnaire and signed a written informed consent prior to testing.

The subjects visited the laboratory on 2 occasions separated by at least h and were instructed not to perform upper body exercise h prior to each visit. Surface electromyographic EMG and mechanomyographic MMG signals were simultaneously recorded from the biceps brachii muscle. The amplitude of the MMG signal, however, can provide information regarding motor unit recruitment and the frequency content is qualitatively related to the global firing rate of the activated motor units[ 8 - 10 ]. For both sexes, from pretest to posttest EMG mean power frequency and MMG amplitude decreased, but returned to pretest levels after 5-min of recovery.
