Feasibility Study of a Neuromuscular Fatigue Test and Associated Hemodynamic Responses: Application in Healthy Volunteers for Use in Patients with Chemotherapy-treated Breast Cancer

"Baseline measurements of neuromuscular function and hemodynamic responses will be done. Investigators will then assess the mechanoreflex activation using the experimental technique of passive leg movement (PLM).~Following the PLM and the neuromuscular function baseline assessments, participants will perform four consecutive blocks, each consisting of a fatigue task followed by post-exercise circulatory occlusion (PECO). Neuromuscular function, assessed through maximal voluntary contraction (MVC) and quadriceps twitch techniques, will be measured before the fatigue task and after PECO in each block. Participants will perform 2-minutes isometric quadriceps sustained contraction at 20% MVC to induce exercise-induced neuromuscular fatigue. Hemodynamic responses will be measured during the PECO to isolate to the metaboreflex by inflating a cuff over the right thigh for a 2 minutes duration. After the PECO, the thigh cuff will be deflated, and neuromuscular function will be reassessed."
