This study analysed the changes in the electromyographic activity (EMG) of the vastus lateralis muscle (VL) during an incremental maximal oxygen uptake test on a treadmill. A breakpoint in the integrated electromyogram (iEMG)-velocity relationship has already been interpreted in two ways: either as a sign of neuromuscular fatigue or as an expression of the(More)
Mechanical and neural activation changes that accompanied muscle isometric training were studied in males. Training and testing sessions consisted of right elbow isometric flexions. Each experimental group was trained during 5 wk at one of the following angles: 25, 80, and 120 degrees. Bipolar surface electromyogram (EMG) was recorded from the biceps(More)
This study analyses the changes in the electromyographic activity (EMG) of six major muscles of the leg during an incremental running test carried out on a treadmill. These muscles, the gluteus maximus (GM), biceps femoris (BF), vastus lateralis (VL), rectus femoris (RF), tibialis anterior (TA) and gastrocnemius (Ga) are known to have quite different(More)
The overload imposed on the neuromuscular system under Electrostimulation (ES) can be expressed by applied current intensity or by Electrically Evoked Torque (EET). The aim of this study was to discern which of these two parameters is the one which is determinant for the efficacy of training by ES. Test and training involved isometric contraction of the(More)
The hypothesis that critical power (CP) is significantly lower than the maximal aerobic power of the knee extensors has been tested in nine endurance-trained subjects, seven gymnasts and seven weight lifters. CP was calculated as being equal to the slope of the linear relationship between exhaustion time and work performed at exhaustion on a knee-extension(More)
The muscle pronator teres was studied by surface electromyography during elbow flexion in a horizontal plane. The forearm was in semi-pronation and movement was performed at various velocities. A quantitative comparison was made between pronator teres activity and two main elbow flexors, biceps brachii and brachioradialis. The mean timing of the onset of(More)
A possible dependence of critical power (CP) and the Y-intercept of the work/exhaustion time relationship (Y intercept) on maximal muscular strength of the same muscle group has been studied in nine endurance-trained subjects, seven gymnasts, and seven weight-lifters. CP was calculated as being equal to the slope of the linear relationship between(More)
