Superimposed tendon vibration during intermittent isometric knee extensions: effects of contraction intensity and sex
Description
This dataset explores the acute effects of superimposed local vibration (SLV) during intermittent isometric knee extension contractions performed at 30% and 50% of maximal voluntary isometric contraction (MVIC) in healthy adults (n = 52). The first column corresponds to the participant identification number. All variables follow the format: AAAAA_BB_CCC AAAAA – Outcome variable TTF: Time to task failure (s) TTI: Torque-Time integral (N·m·s) Tmax: Maximal voluntary isometric torque (N·m) RFD50-100: Rate of Force Development between 50 and 100 ms after contraction onset (N·m) RMSMAX: RMS values of the quadriceps muscles (Quad) during MVIC (mV) RMSFATIGUE: RMS values of the quadriceps muscles (Quad) during the fatiguing task (in percentage of RMSMAX Quad PRE) CoactFATIGUE: RMS values of the biceps femoris during the fatiguing task (in percentage of RMSMAX BF PRE) BB – Experimental condition CON: Control condition (no vibration) SLV: Superimposed local vibration applied to the quadriceps tendon during contractions CCC – Time point / task phase PRE: Values obtained before the fatiguing task POST: Values obtained immediately after task termination First: Values obtained from the first contraction Last: Values obtained from the last contraction
