background: daily increased rate of anterior cruciate ligament (acl) injuries in athletes calls for more investigation in these patients to differentiate copers from noncoper acl-deficient (acld) knees as soon as possible. objectives: the current study aims to introduce a new electromyographic protocol, named voluntary response index (vri), that might help to categorize and differentiate patien...

The songbird vocal organ, the syrinx, is composed of two sound generators, which are independently controlled by sets of two extrinsic and four intrinsic muscles. These muscles rank among the fastest vertebrate muscles, but the molecular and morphological foundations of this rapid physiological performance are unknown. Here we show that the four intrinsic muscles in the syrinx of male European ...

This investigation was designed to examine 1) the relationship between motor-unit activation (as recorded by integrated EMG) and speed of contraction and 2) the relationship between mechanical work, power output, peak torque, average torque, and both velocity of movement and integrated electromyographic recordings in the elbow flexor muscles. A series of isokinetic contractions of the elbow fle...

[Purpose] We investigated the effects of shoulder flexion loaded by an elastic tubing band during squat exercises, by assessing electromyographic activities of the gluteus maximus and gluteus medius. [Subjects] In total, 17 healthy males were recruited. [Methods] Participants performed squat exercises with and without shoulder flexion loaded by a tubing band. Gluteal muscle activities during th...

Relationships between an index of running economy (VO2 per distance) and the temporal electromyographic characteristics of leg muscles were quantified in female runners. Sixteen women performed a 30-min treadmill run at a speed designed to elicit a hard rating of perceived of exertion. Near the end of the run, oxygen uptake, video, and electromyographic data were collected simultaneously. Measu...
