Changes in the angle-force curve of human elbow flexors following eccentric and isometric exercise

Changes in inflammatory mediators following eccentric exercise of the elbow flexors.

The aims of this study were to examine the plasma concentrations of inflammatory mediators including cytokines induced by a single bout of eccentric exercise and again 4 weeks later by a second bout of eccentric exercise of the same muscle group. Ten untrained male subjects performed two bouts of the eccentric exercise involving the elbow flexors (6 sets of 5 repetitions) separated by four week...

Responses of elbow flexors to two strenuous eccentric exercise bouts separated by three days.

This study investigated whether the second eccentric exercise performed 3 days after the initial bout would exacerbate muscle damage and retard the recovery. Fifty-one athletes performed 30 eccentric actions of the elbow flexors using a dumbbell weighted 100% of the maximal isometric force (MIF) at the elbow joint angle of 90 degrees (ECC1). Three days after ECC1, all subjects except those in t...

Changes in the Muscle Strength of the Elbow Flexors

Relationship between Force and Histological Changes in Mouse Anterior Crural Muscles Following Eccentric Exercise

The purpose of this study was to determine the relationship between mononuclear cell number and maximal isometric force (Po) following active lengthening exercise. The tibialis anterior muscles (TA) of mice were actively lengthened 120 times from a dorsiflexed to plantarflexed position in 300 ms while stimulating the peroneal nerve (100 Hz, 310 ms). Po at 150 Hz was measured immediately before ...

Comparison of responses to strenuous eccentric exercise of the elbow flexors between resistance-trained and untrained men.

This study compared resistance-trained and untrained men for changes in commonly used indirect markers of muscle damage after maximal voluntary eccentric exercise of the elbow flexors. Fifteen trained men (28.2 +/- 1.9 years, 175.0 +/- 1.6 cm, and 77.6 +/- 1.9 kg) who had resistance trained for at least 3 sessions per week incorporating exercises involving the elbow flexor musculature for an av...
