Features of adaptation of the neuromuscular apparatus of badminton players to asymmetric loads

Aim. The paper aims to study electromyography data of the forearm muscles (anterior group) in badminton players in various conditions. Materials and methods. A survey of 40 badminton players and 49 non-athletic males were carried out. The subjects were divided into 3 groups: 8-12 years, 13-16 years and 17-21 years. The research method was surface electromyography (EMG). A comparative analysis of the total bioelectrical activity of the forearm muscles (musculus brachioradialis) of the dominant and non-dominant arms was carried out in three states: background measurement, voluntary tension, and voluntary relaxation. Results. In badminton players of all age groups, there is an increase in the tension of the forearm muscles against intensive load. Also, in all three states, muscle asymmetry of the arms was revealed, especially in teenagers and adolescents. Conclusion. Muscle asymmetry of the arms in young males from the control group was recorded only at rest and during voluntary relaxation. In badminton players, asymmetry increases with an increase in sports experience and with an increase in training loads of a special orientation. It can be assumed that athletic performance is largely determined by the presence of asymmetry.
