The torque-velocity relationship in large human muscles: maximum voluntary versus electrically stimulated behaviour.
The in vivo maximum voluntary torque-velocity profile for large muscle groups differs from the in vitro tetanic profile with lower than expected eccentric torques. Using sub-maximal transcutaneous electrical stimulation has given torque-velocity profiles with an eccentric torque plateau ∼1.4 times the isometric value. This is closer to, but still less than, the in vitro tetanic profiles with pl...
متن کاملThe effect of isometric contractions of upper and lower limb muscles on the ultrasonic thickness of the transversus abdominis muscle
Background: The transverse abdominis (TrA) muscle is one of the most important muscles that contribute to the stability of the lumbar spine. Strengthening of trunk muscles that have a significant role in trunk stability is very important in the field of professional sport, sport medicine and rehabilitation of patient with low back pain (LBP). Identifying the exercises that can improve the stren...
متن کاملCorticospinal-evoked responses in lower limb muscles during voluntary contractions at varying strengths.
This study investigated corticospinal-evoked responses in lower limb muscles during voluntary contractions at varying strengths. Similar investigations have been made on upper limb muscles, where evoked responses have been shown to increase up to approximately 50% of maximal force and then decline. We elicited motor-evoked potentials (MEPs) and cervicomedullary motor-evoked potentials (CMEPs) i...
متن کاملMaximal Voluntary and Electrically Stimulated Torque – Angle – Angular Velocity Profiles of the Knee Extensors and Flexors
In vivo measurements of maximum voluntary force – velocity show differences to the in vitro tetanic profile, with eccentric forces not increasing much above isometric and tending to decline with increasing lengthening velocity. Using transcutaneous electrical stimulation maximal eccentric torque has been found to be 1.4 times the isometric value and does not drop off at higher eccentric velocit...
متن کاملThe Effect of Voluntary and Electrically Stimulated Quadriceps Muscle Fatigue on Postural Control
Purpose: The present study aimed to investigate the effect of voluntary and electrically stimulated quadriceps muscle fatigue on postural control. Methods: Sixteen healthy young males participated in this quasi-experimental study. All subjects performed two fatiguing exercises with equal intensity of isometric maximal voluntary contraction: Voluntary (VOL) and Electrical Stimulation (ES). The ...
