It \nmay stem from disturbances in processes at or distal to the neuromuscular junction, referred to \nas peripheral fatigue, as well as proximal to it, referred to as central fatigue. Central fatigue can \nbe further distinguished into spinal or supraspinal fatigue. No studies have assessed central \nfatigue or the degree of supraspinal fatigue after exhaustive stretch-shortening cycle (SSC) \nexercise. Therefore, the purpose of the present study was to investigate the acute corticospinal \ncontribution to neuromuscular fatigue following exhaustive SSC exercise. Ten healthy active \nindividuals were assigned to the fatigue group (FAT) and completed the SSC fatigue protocol. \nTen different individuals did not engage in any exercise, serving as control group (CON). \nMaximal voluntary contraction (MVC) and tibial nerve electrical, as well as primary motor \ncortex magnetic stimulation evoked force and surface EMG (M-wave and MEP) responses, \nwere recorded before and immediately after SSC exercise to assess voluntary activation ratio \nand corticospinal excitability. To assess the magnitude of acute exercise-induced fatigue, \nassessments of neuromuscular and corticospinal functions were completed within 3.5 minutes \nafter exercise cessation. Ankle plantar flexor MVC for FAT decreased by ~18.12% (p < 0.001; \nd = 0.89) after exhaustive SSC exercise. Cortical voluntary activation ratio for FAT declined \nfrom 90.3 \u00b1 10.1% at baseline to 77.4 \u00b1 15.4% after SSC exercise (p = 0.001, r = 0.79). \nVoluntary activation ratio measured via motor nerve stimulation declined from 92.7 \u00b1 6.8% at \nbaseline to 82.3 \u00b1 12.9% after SSC exercise (p = 0.037; r = 0.66). Resting twitch amplitude \ndeclined by ~ 9.2% (p = 0.03; d = 0.34). Silent period duration lengthened by ~13.5% (p = 0.01; \nd = 1.38), while MEPs remained unchanged. Thus, exhaustive SSC exercise induced \nconsiderable central fatigue and caused an impairment in the capacity of the motor cortex to \ndrive the ankle plantar flexors along with increased level of intracortical inhibition. As a result, \nmaximum force-generation capacity was significantly reduced by central fatigue as well as by \nperipheral mechanisms following SSC exercise.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-07-03T08:02:52Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-07-03T08:02:52Z (GMT).
