Purpose: to define the indicators of physical fitness of taekwondo players of 15-17 years old. Material and Methods. 120 taekwondo players took part in the research: in the 1st group – sportsmen of 15 years old, in the 2nd group – 16 years old in the 3rd group – 17 years old, 40 in each age group. The qualification of sportsmen is 1-2 adult category. The following methods were used in the research: analysis and generalization of scientific-methodical and special literature, information on the Internet, pedagogical testing, methods of mathematical statistics. The statistical analysis of the obtained data and correlation analysis between indicators of physical fitness was carried out with the help of the licensed program MS Excel (2010). Indicators of descriptive statistics were determined: arithmetic mean, standard deviation, error of arithmetic mean. Results: the analysis of physical fitness of taekwondo players that by average indicators during 15-17 years the results differ on average from: 0,12 to 57,96 %. The greatest difference in indicators of physical fitness of taekwondo players of 15-17 years old – 57,96 % was observed in the test of flexion of extension of hands in a lying rest, and the least 0,12 % in a run on 400 m. High correlations between: pulling up on a high crossbar and flexion of extension of hands in a lying support r=0,597 were found in 15-year-old of taekwondo players, and high inverse correlations were found between indicators: running on 100 m and jumping on a rope for 1 min r=-0,570, in 16-year-old of taekwondo players - between indicators: torso tilt forward from a sitting position and a rope jump for 1 min r=0,749; change of stances for 1 min and a rope jump for 1 min r=0,792; change of stances for 1 min and a torso tilt forward from a sitting position r=0,739, 17-year-old of taekwondo players – between: index, 200 m run and 100 m run r=0,579. Conclusions. The research has established that average statistical indicators of physical fitness of sportsmen with age, by the majority of indicators, become more homogeneous, in 17-year-old of taekwondo players V=8,53-51,19 %, in 16-year-olds – V=10,38-46,58 %, and in 15-year-olds – V=10,31-60,02 %. With age, there is a decrease in high inverse correlations and an increase in the number of medium correlations. This is due to the fact that with age, the improvement of physical fitness indicators occurs due to the improvement of special physical fitness.

Purpose: comparative analysis of the manifestation of morphological and functional indicators of taekwondo athletes aged 14–15 years. Material and Methods: The study involved 60 taekwondo athletes aged 14–15 years. Athletes’ qualification 1-2 category. At least 5 years of experience in Taekwondo WTF. The assessment of morphological and functional indicators of taekwondo athletes was carried out at the age of 14 and 15 years. Research methods: analysis and generalization of scientific, methodological and special literature, information on the Internet; anthropometric methods; index method; methods of mathematical statistics. Results: The average body weight of taekwondo athletes aged 14-15 increased by 16,5%, and body length by 4,7%. The indicator of chest excursion increased by 4,8%, carpal dynamometry indicators of the left hand increased by 15,2%, the right hand - by 15,3%. 33,6% of 15-year-old athletes are underweight in terms of body mass index, 2,9% are overweight; 14 year olds: 21,56% underweight, 13,7% overweight. Athletes aged 14–15 have a normosthenic body type. According to the constitution of the physique, 7,84% of 14 year old athletes have a strong physique, 15,68% have a good physique, 5,88% have an average physique, 27,45% have a weak physique, 43,15% have a very weak one. 12,12% of 15-year-old taekwondo athletes have a strong physique, 24,24% have a good physique, 9,1% have an average physique, 24,24% have a weak body, and 30,3% have a very weak body. 13,7% of 14-year-old taekwondo athletes have good physical development, 3,9% - average, 76,4% - weak 15-year-old athletes: 17,6% - good physical development, 14,8% - average, 67,6% - weak. Conclusions: The study of morphological and functional indicators is one of the important criteria for the training of taekwondo athletes, the use of indices allows you to move on to relative indicators, that is, to standardize anthropometric indicators and supplement them. This will contribute to the rational selection of means and methods of training athletes, taking into account their personal characteristics. Our research can be used in monitoring the functional state of athletes involved in taekwondo WTF.
