    Skeletal muscles are heterogeneous tissue containing different types of muscle fibers. Their distribution depends on heredity, type of exercise, sex, age, and muscle type. In addition, stem cells (myosatellitocytes) are found in large amounts in the muscle tissue. Myosatellitocytes are the main material for regeneration of microtears of muscle fibers always occuring during intensive physical exercises. Myosatellitocytes are capable of long-term storage in an inactive “dormant” state, but they can be rapidly activated to provide an efficient repair of damaged muscle fibers. The metabolism of myosatellitocytes and myoblasts and their migration into the damaged area are regulated by a complex system of cytokines and transcription factors, the activity of which depends on many factors. Microtears initiating the development of the inflammatory process and activation of myosatellitocytes is a determining factor. The study into molecular mechanisms of the relationship between inflammatory processes in muscle tissue and changes in myosatellitocyte metabolism is of fundamental importance and is necessary for the selection of efficient methods for muscle tissue recovery.

    Validation of the Software-Hardware Complex “Rytm” for Measurement of the RR Intervals and Heart Rate Variability Analysis During Exercise and Recovery Period
    (2021-04-05) Vovkanych, L.; Boretsky, Yu.; Sokolovsky, V.; Berhtraum, D.; Kras, S.; Вовканич, Л.; Борецький, Ю.; Соколовський, В.; Берхтраум, Д.; Крас, С.
    The study purpose was estimation of the accuracy of RR time series measurements by SHC “Rytm” and validity of derived heart rate variability (HRV) indexes under physical loads and recovery period. Метою дослідження була оцінка точності вимірювань часових рядів кардіоінтервалів та отриманих на їхній основі показників варіабельності серцевого ритму (ВСР) за допомогою програмно-апаратного комплексу (ПАК) «Ритм» в умовах фізичних навантажень та періоду відновлення/
