Three maximal isometric contractions
were exerted against the EN-TreeM pulley and the maximum force reading obtained from the electronic strain gauge.
Some of them also demonstrated positive speeds test, lift off test and painful isometric contraction
of supraspinatus (Table 1).
Acute effect of repeated maximal isometric contraction
on electromechanical delay of knee extensor muscle.
FCWS = fastest comfortable walking speed, KE = knee extensor, MVIC = maximum voluntary isometric contraction
, PF = plantar flexor, SSWS = self-selected walking speed.
Effect of muscle mass and intensity of isometric contraction
on heart rate.
Effect of stretching on agonist-antagonist muscle activity and muscle force output during single and multiple joint isometric contractions

of the Biceps Brachii Muscle", Journal of Electromyography and Kinesiology, Elsevier, vol.
The surface EMG of the extensor carpi radialis, the extensor digitorum and the superficial flexor digitorum were recorded during maximum and sub-maximal isometric contractions
of five seconds in flexion and extension of the wrist.
However there are few studies which investigated effects of electrical stimulation and maximal volun-tary isometric contraction
(MVIC) on isokinetic strength on literature.
McMeeken et al (2004) used an abdominal hollowing task that may allow more shortening of transversus abdominis than the isometric contraction
used by Hodges et al (2003).
36) Clark et al (37) therefore submitted that the sex difference observed during isometric contraction
was not influenced by torso length, as there was no significant relationship between torso length and endurance time.
This study examined whether arm position and muscle activity affect the duration of an isometric contraction
