Detecting the velocity of the muscle contraction
نویسندگان
چکیده
The dynamics of skeletal muscle mechanical response cannot be measured selectively and noninvasively using existing methods. Therefore new, selective and non-invasive method (Tensiomyography) that provide information about skeletal muscle contractile properties, like: speed of muscle contraction, time needed for relaxation after contraction, recruitment pattern and muscle potentiation/fatigue, was developed. Method uses alter approach and detects thickening of the muscle belly. A result of the measurements speaks about intrinsic properties of the muscle belly without being affected by connective and passive surrounding tissue. Importance of the time parameters of the muscle contraction is of the essential value studying muscle illnesses, rehabilitation processes, training dimensioning and muscle adaptation. Measuring setup and equipment needed were developed to hit commercial and laboratory environment and offers easy-to-operate universal diagnostic tool.

Introduction: Repetitive strain injuries are one of the most prevalent problems in occupational diseases. Repetition, vibration and bad postures of the extremities are physical risk factors related to work that can cause chronic musculoskeletal disorders. Repetitive work on a computer with low level contraction requires the posture to be maintained for a long time, which can cause muscle fatigu...

Objectives: The results of a few studies about the effects of ankle brace on muscles function during the performance of different tasks are contradictory. Moreover, the effect of brace on the co-contraction of ankle muscles is undiscovered. Therefore, the present study investigated the effect of brace usage on the ankle muscles activity and co-contraction during single-leg landing. Methods: Fi...
