Objective. Determination of the nature of adaptation of skeletal muscles when performing special exercises in badminton.Materials and methods. The study involved 6 students, aged 18 - 20, of Gomel State Medical University practicing badminton. Testing of the functional state of skeletal muscles was carried out by myometrics method using myometer “MYOTON-3” and software “Myoton”.Results. The results of the study showed that the application of special exercises during 8-week microcycles promotes the formation of skeletal muscle adaptation to the performance of special competitive exercises of high intensity, expressed in the frequency of oscillation in a relaxed state in the range of 11-15 Hz. The processes of adaptation of muscular activity have an impact on improving the trajectory of the athlete’s body links, there is a decrease in the load on the articular joints of the upper limbs, expressed in terms of the muscle decrement index of at least 0.6 c.u., and the stiffness index of at least 0.45 N/m.Conclusions. Changes in the functional state of skeletal muscles as a result of a targeted impact contribute to an increase in strength potential, which leads to an increase in the performance of game activity.
