Human subjects generated a specified level of isometric torque with elbow flexor muscles of one arm, the reference arm, under visual feedback. They were then asked to generate what they perceived to be the same level, with the other arm, the indicator, but with no visual feedback. A number of torque levels, between 2% and 30% of maximum were used in the(More)
1. Experiments were performed to test the ability of human subjects to match forces in their elbow flexor muscles following eccentric exercise of one arm and, in a second series, after biceps brachii of one arm had been made sore by injection of hypertonic saline. 2. In the force-matching task, the elbow flexors of one arm, the reference arm, generated 30%(More)
In human subjects the triceps surae of one leg was exercised eccentrically by asking subjects to walk backwards on an inclined treadmill. Before the exercise controlled local pressure, applied to the muscle with an electromagnet, produced mild soreness, which was reduced when the pressure was combined with vibration. When delayed-onset muscle soreness(More)
During eccentric exercise contracting muscles are forcibly lengthened, to act as a brake to control motion of the body. A consequence of eccentric exercise is damage to muscle fibres. It has been reported that following the damage there is disturbance to proprioception, in particular, the senses of force and limb position. Force sense was tested in an(More)
These experiments are concerned with the ability of human subjects to match isometric torque in their elbow flexor muscles when biceps of one arm is made sore. Pain was induced by injection of hypertonic saline. Subjects were asked to generate a level of torque, 30% of maximum, with one arm, the reference arm. To achieve the required torque, subjects were(More)
