ABSTRACT

The purpose of this study was to examine exercise-induced arterial adaptations in elite Judo male and female athletes. 27 male Judo athletes (age 24.06 ± 2 years), 11 female Judoka (age 24.27 ± 1 years), 27 sedentary healthy men (age 24.01 ± 2 years) and 11 women (age 24.21 ± 1 years) participated in the current study. The examined vessels included brachial, radial, ulnar, popliteal, anterior and posterior tibial arteries. The experimental parameters were recorded with the use of Duplex ultrasound at rest. Diastolic diameter and blood mean flow velocity of the examined arteries in Judo athletes were found to be both significantly increased (p < 0.05) compared to the findings of the control groups. In male Judo athletes the brachial (p < 0.001), radial (p < 0.001), and anterior tibial artery (p < 0.001) presented the highest difference on the diastolic diameter, compared with the control male group. In female Judo athletes, ulnar (p < 0.001), radial (p < 0.001), and brachial (p < 0.001) arteries illustrated the highest diastolic diameter. The highest blood mean flow velocity was recorded in ulnar (p < 0.001) and popliteal arteries (p < 0.001) of the Judo athletes groups. Recording differences between the two genders, male participants presented larger arteries than females. Conclusively, Judo has been found to be a highly demanding physical sport, involving upper and lower limbs leading to significant arterial adaptations. Obtaining vascular parameters provide a useful tool to the medical team, not only in the direction of enhancement of the efficacy of physical training, but in unknown so far parameters that may influence athletic performance of both male and female elite Judokas.

Key words: Diastolic diameter, blood mean flow velocity, duplex sonography, judo athletes


           Key Points
  • Judo athletes demonstrated a general homogenous increase of the arterial functionality of the upper and lower limbs compared to the control groups.
  • Diastolic diameter found to be significantly increased in male and female Judo athletes, highlighting the effects of exercise training on the vascular system.
  • Judo athletes had had statistically significant increase of the blood mean flow velocity in all examined arteries, compared with the relevant control group.
  • The current study underscores the impact of Judo training on the structure and the function of the arterial system.
  • Clinically, the increased arterial parameters in elite Judo athletes may be essential elements for improved athletic performance.
  • Sports medicine practitioners should give special concern to the vascular functionality for several physiological and medical tests.
