Human endurance--mind or muscle?
Two investigations have been carried out. The first studied the effects of autonomic blockade on the cardiovascular response to a step test, a 50% maximum isometric grip test and a Valsalva manoeuvre: the step test was of 5 minutes duration and the other two for as long as possible. beta adrenergic blockade by propanolol diminished the blood pressure and pulse rate response to both the step tes...

BackgroundElectrical stimulation has been used to train paralyzed muscle. However, papers often cite that rapid fatigability of muscle compared to voluntary effort. Methods and Procedures; The literature is reviewed over the last 25 years examining the normal recruitment order of motor units, the impact of recruitment order, stimulation frequency and asynchronous recruitment on muscle strength ...
متن کاملEndurance exercise activates matrix metalloproteinases in human skeletal muscle.
In the present study, the effect of exercise training on the expression and activity of matrix metalloproteinases (MMPs) in the human skeletal muscle was investigated. Ten subjects exercised one leg for 45 min with restricted blood flow and then exercised the other leg at the same absolute workload with unrestricted blood flow. The exercises were conducted four times per week for 5 wk. Biopsies...
متن کاملTheory of Mind in Human-Robot-Communication: Appreciated or not?
Social robots play a more and more important role in our society.
