Three appropriate efforts were eventually selected as the main test.
Then the main test was performed with five repetitions. Participants were asked to practice walking more times to familiarize with the test. Data collection was done at a frequency of 1000 Hz. In the next step, chloride–silver electrodes were placed at inter–electrode distance of 20 mm. After determining the electrode placement, the areas were cleaned with alcohol in order to reduce the resistance of the skin. Target areas of eight muscles of the gluteus medius, vastus lateralis, rectus femoris, medial hamstring, lateral hamstring, tibialis anterior, gastrocnemius and soleus were determined using Seniam instructions. In order to measure the pattern of muscle activity during walking, a biometric electromyography system (eight–channel model PS850 UK) was used. After the completion of the consent form, the measurement process was started. Before starting the research, the method of implementation and the necessary explanations were provided about the experiment. The active and inactive subjects did not have a history of neurological problems, traumatic injury, visual impairment, balance, or any history of athletic injury. Twenty–six subjects participated in two active and inactive groups as available samples in this study. Methods: Young men in Imam Ali’s technical and vocational school formed the statistical population of this semi–experimental study. In this research, the effect of exercise on muscle synergies in walking patterns studied.
Considering that walking patterns are affected by changes in the nervous system and muscle fibers, the effect of exercise on muscle synergies has not yet been clarified. On the other hand, changes in the nervous system and muscle fibers occur with physical activity. Identifying basic neural patterns can be effective in understanding the mechanism and development of the movement patterns. A concept recently developed to understand the gait pattern is muscle synergy, which is defined as muscle coordination in order to achieve a specific neural target. Background & Objective: Some researchers studied on gait pattern however, the complex neuromuscular system has led to extensive research in this area.
