Abstract

The purpose of the present study was to determine the effects of physical and observational practices on electromyography features of active muscles in high badminton serve. Thirty non-athletic female students (aged 18–24 years) were randomly assigned to three physical, observational, and combined training groups after pre-test. Surface electromyography was done for biceps, triceps and middle part of the deltoid, during the pre-test badminton high serve. All participants underwent an electromyography assessment after 4 sessions of practice. A mixed analysis of variance was used to analyze data. There was significant decrease between pre- and post-test in activity time, mean, and peak normalized activity of biceps and deltoid muscles. From a neurophysiological point of view, observation will activate a mirror mechanism that leads to facilitation of movement for imitating act.
