The aim of the study was to evaluate complex profile of the taekwondo WTF competitors with respect to functional parameters, flexibility a dynamometric measures, and examination of the motor system from the point of view of muscle dysbalances and eventual differences form the physiological position of the particular segments. Sample of elite taekwondo competitors (n = 31) consisted from 17 males (mean (±S.D.) age = 17,9±1.91 let, height = 178,7±5.11 cm, body mass = 68.4 ± 7.01 kg, BMI = 21.39 ± 1.75 kg.m–2, VO2 max 60.0 ± 3.8 ml.kg–1min–1) and
14 females (mean age = 16.5±1.27 let, height = 162.9 ± 7.05 cm, body mass = 55.9 ± 6,89 kg, BMI = 20.98 ± 1.35 kg.m–2, VO2 max 52.1 ± 2.8 ml.kg–1min–1) at a age range 15 to 21 years. In the both groups there was observed higher incidence of weakening of fixators of scapulae and elevation of the left shoulder. In addition, male and female competitors exhibited substantial differences in unwinding of single sections of the spine. Analysis of muscle dysbalances showed a high percentage of shortening of m. trapezius and shortening of knee flexors, both in male and female competitors. Verf.-Referat
