В статті представлені результати показників функціональних систем організму велосипедистів (ВМХ) 14-15 років під впливом специфічних навантажень в умовах рівня моря в відновному, в ударних мікроциклах та середньогір'я в ударному мікроциклі. Метою роботи явилося визначення змін серцево-судинної та дихальної систем організму велосипедистів 14-15 років в передзмагальному та в змагальному мезоциклах. Встановлено зміни показників діастолічного артеріального тиску, частоти серцевих скорочень, максимального споживання кисню та життєвої
ємності легенів в різних умовах тренування.
The article presents the results of the functional systems of the body cyclists 14-15 years under the influence of specific loads in terms of sea level during the recovery and shock microcycles, as well as in the middle mountains of shock microcycle. The aim of this work was to determine changes of cardiovascular and respiratory systems of the body cyclists 14-15 years in precompetitive and competitive mesocycles. The changes in the indices of diastolic arterial pressure, heart rate, maximum oxygen consumption and vital capacity of the lungs in different conditions of training. According to researchers in sport exercise is an integral stage of the training process, the duration of which is from three to six weeks. Most often are used four weeks training process. Many experts in sport studies the problem of sports training of young athletes, the conditions for constructing the structural elements of a training lesson, mesocycles, microcycles. The result of the training and competitive loads in a young body needs to control all the functions and systems of the body, particularly during growth. The training programs of many sports schools in Ukraine are structured in such a way that at a young age body receives overload, which subsequently leads to sports injuries, pathological diseases of the heart. Our research were carried out in the autumn at the end of several microcycles, both above sea level and in the middle mountains, where blood pressure, heart rate, maximum oxygen consumption, and lung capacity were collected from BMX athletes aged 14-15 years. The results showed that under the influence of specific physical activity for cyclists BMX 14-15 years statistically changed diastolic blood pressure, heart rate, maximal oxygen uptake and vital capacity (p<0.05).
