Electrical stimulation has been widely used in the field of sport training or functional rehabilitation to enhance strength training and to assess voluntary muscle activation. Two superimposed techniques can be used: 1) the twitch interpolation technique, which consists of interjecting an electrical stimulus onto the muscle nerve; and 2) the percutaneous superimposed electrical stimulation technique, where the stimulation is applied to the muscle belly. These two superimposed techniques can be used to evaluate the ability to fully activate a muscle.
Temperature is important for muscle function. Muscle contraction and relaxation becomes quicker, development of power increasing as the temperature of the body raises. Immoderate temperature of the muscle, as a result, can decrease physical efficiency. However it is unclear how muscle heating can affect superimposed pulse force, therefore our aim was to determine and compare variant temperature affect on additionally activated quadriceps femoris muscle during isometric load.
The study was performed at Lithuanian Academy of Physical Education. The subjects were 10 healthy adult men (age 22,1 ± 2,3 years, weight 72,3 ± 4,9 kg, height 178 ± 5,7 cm) who were not actively going in for sports. The study was consisted of two stages. During the first stage subjects were tested under control conditions. During the second stage (was performed after two weeks) subjects were tested, when their muscles were heated. Quadriceps femoris... [to full text]
