HEART RATE INDICATORS WITHIN TRAINING EXERCISES OF UKRAINIAN AND CHINESE BADMINTON PLAYERS AGED 10-12 YEARS

We have found the contradiction between the current requirements of competitive activities and insufficient justification of the methodological provisions of various aspects of the training of qualified badminton players, which led to the urgent scientific and practical task. An important aspect of this is the comparison of exercise load data (in terms of heart rate) between Ukrainian and Chinese badminton players in the same age group. Aim: to compare the heart rate of Ukrainian and Chinese badminton players aged 10-12 years within the training exercises. Material & Methods. We have used theoretical analysis and generalisation of scientific and methodological data, pedagogical observations of heart rate during training exercises of badminton players aged 10-12 years (the first zone provided for indicators within 124 bpm, the 2 – 125-145 bpm, the 3 – 146-166 bpm, the 4 – 167-187 bpm, and the 5 – more than 188 bpm), methods of mathematical statistics. During 2019, training exercises with the participation of 102 Ukrainian and 112 Chinese badminton players aged 10-12 were analysed. Results. Chinese athletes perform more intense loads, which are characterised by increased heart rate indicators and reflected in the share of those being in the fifth heart rate zone. At the same time, Ukrainian badminton players achieve a significantly higher (p≤0.01) average heart rate level by compensating for the use of marginal and near-marginal intensity in exercises, by increasing the amount of exercise performed in the third and partially second heart rate zones. Significant predominance (p≤0.01) of Chinese badminton players was found in the total duration of training sessions (20.03%), absolute and relative values of being in the first (59.04−87.12%) and the fifth (230−297%) heart rate zones, the number of moving to the fifth heart rate zone (173.02%). Ukrainian badminton players significantly (p≤0.05) outperform their Chinese peers in the average heart rate indicator of the athlete in training (2.72%), the absolute values of being in the second heart rate zone (16.91%), absolute and relative values of being in the third heart rate zone (16.95-31.11%). Conclusions. During the preparation of Chinese athletes, more attention is paid to the systematic and gradual increase in physical load (in terms of volume and intensity) compared to the Ukrainian peers. Based on the identified structure, we assume that moving from one level of physical load to another one takes place according to the alternation of loads of different intensity and volume.
