Effect of asymmetric load on the stereotype of running.
Holíková, Dana ; Pánek, David (advisor) ; Satrapová, Lenka (referee)
Title: Effect of asymmetric load on the stereotype of running. Objectives: The aim of this experimental work is to evaluace the electromyographic activity of selected muscles when running without load and with load on the treadmill, and the co- current assessment of the impact of asymmetric load on the lateral weight distribution. Methods: Six recreational runners underwent the experiment during which we monitored electrical activity of m. deltoideus pars anterior, m. trapezius pars ascendes et descendens, lumbar paraspinal muscles, m. gastrocnemius lateralis and m. tibialis anterior while running without load and with load on the periphery of the upper right extremity. For the experiment a motor treadmill at a constant speed of 10 km/h was used and a 0,5 l PET bottle completely filled with water was applied as the load. Changes of lateral weight distribution were assessed having investigated stance on two scales. The measured values were statistically evaluated. Results: Within the group of all the probands it was proved that there existed an impact on normalized average amplitude of EMG signal at left-oriented m. gastrocnemius lateralis. The hypothesis of the influence of asymmetric load on the lateral weight distribution was not demonstrated. Keywords: endurance running, surface...
