Abstract
Measurement of skeletal muscle response is interesting for physicians in diagnostics (Buchthal et al., 1974, Dubowitz et al., 1987), rehabilitation (Milner-Brown et al., 1988, Scott et al., 1986, Zupan, 1992), surgeons, sport physicians, scientists (Hudlicka et al., 1984, Salmons et al., 1969), with interest in physiology and muscle function. Most of measuring methods in use is based on measuring muscle force as in torque measuring methods. Disadvantage of torque based measuring method is poor selectivity due to system of muscles act upon single joint. Invasive measuring methods can be more acurate but they cause injuries of tissue. Measuring method used by the research group - tensiomiography (TMG) - is a non-invasive method based on measurement of radial displacement of muscle belly. Displacement sensor is pressed to the skin above measured muscle with initial pressure. When muscle contracts muscle belly enlarges due to constant muscle volume. The muscle belly enlargement can be detected on a skin surface. In foregoing research a measuring device has been developed, sensor setup parameters were optiomized and measured results were compared against torque in an an adequate joint, against histochemical analyses and against electro myographic recordings of muscle activity during its contraction. Response on voluntary and electically stimulated contraction was measured. Shape of muscle belly response to electrical stimulation detected by displacement sensor differs from the one detected by torque measurement system. Our studies revealed a connection between displacement sensor response shape and muscle contraction speed. In proposed research project muscle responses of several muscles will be analyzedin pupils of fifth and sixth grade of chosen primary schools. Responses of the following muscles will be measured: - m. biceps brachii - m. triceps brachii - m. rectus femoris - m. biceps femoris - m. tibialis anterior - m. soleus. Results of study will be analyzed and an atlas of biomechanical properties of measured muscles in primary school pupils will be created. Analysis will also take sex and other data acquired from sport record into account. The developed atlas will serve as a basis for comparison of basic properties of muscles in measured subject against muscle properties of an average population.
