The vastus lateralis (VL) and rectus femoris (RF) muscles' electromyography (EMG) threshold during cycling exercise was identified. The RF EMG threshold closely relates to the ventilatory threshold (Tvent), offering an alternative assessment method.

Area of Science:

  • Exercise Physiology
  • Muscle Electromyography
  • Cardiorespiratory Fitness

Background:

  • Assessing exercise intensity is crucial for training and performance.
  • The ventilatory threshold (Tvent) is a common indicator of exercise intensity.
  • Electromyography (EMG) thresholds may offer alternative physiological markers.

Purpose of the Study:

  • To identify the integrated electromyography (IEMG) threshold in vastus lateralis (VL) and rectus femoris (RF) muscles.
  • To compare IEMG thresholds with the ventilatory threshold (Tvent) during incremental cycling.

Main Methods:

  • Ten male cyclists underwent a graded exercise test on a cycle ergometer.
  • Oxygen uptake and IEMG activity of VL and RF were continuously measured.
  • Tvent was identified using VE/VO2 and V-slope methods; IEMG thresholds were identified at non-linear increases.

Main Results:

  • An IEMG threshold was identified in all subjects for the RF, but only half for the VL.
  • When identified, the VL IEMG threshold was similar to the RF IEMG threshold.
  • The VO2 at the RF IEMG threshold was not significantly different from Tvent.

Conclusions:

  • The IEMG threshold is more reliably detected in the RF than the VL during incremental cycling.
  • The RF IEMG threshold is closely associated with Tvent.
  • IEMG threshold assessment in the RF may serve as an alternative to Tvent determination.
