![]() ![]() The majority of studies in the field of sports physiology and biochemistry have been focused on endurance athletes, while slightly less research has been carried out on mixed and anaerobic exercise performed with both the upper and lower limbs. The effect of physical stimuli at different intensities, ranges and durations on an athlete’s body has already been the subject of research, and empirical knowledge gained is applicable, allowing sports practitioners to optimise the preparation of athletes for competitions. However, it should be noted that training programmes, especially those for young judo athletes, should include elements aimed at improving mechanisms of oxygen supply to tissues, which further determine recovery rate. Nonetheless, in specific judo fighting, more attention is paid to the processes of improving anaerobic capacity. A high level of aerobic capacity (VO 2max) is one of the predictors of effective fighting, mainly in the second part of the combat. It is also noteworthy to evaluate the same variables under different thermal conditions. The nature of competition in judo requires very good psychophysical preparation, which suggests that attention should be paid to determining, through research, the level of functional, psychological and somatic variables that may affect the way an athlete competes and reaches the final result. Athletic performance is improved when all of these elements are developed simultaneously and reach an optimal level, which is usually associated with maximum levels of variables typical for determining the physical capacity of an athlete. Exercise intensity and recovery intervals should be adjusted to individual potential capabilities and modelled after the completion of each preparation stage. They also provide an opportunity to monitor physiological and biochemical changes induced by special physical training and changes in the rate of post-exercise recovery. Such testing methods make it possible to determine the current level of endurance as well as speed/strength abilities and to define zones of exercise intensity. In this sense, special training programmes prepared by coaches and based primarily on scientific research in physiology and biochemistry contribute to athletic performance. The preparation of athletes of judo for sports competition should include the development of speed, strength, endurance, technical–tactical skills and volitional characteristics. Statistically significant differences were also observed between the first and fourth efforts performed by the LL at 31 ☌ ( p < 0.001) and between the second and third performed using the upper limbs (UL) at an ambient temperature of 21 ☌ Conclusions: Varying ambient thermal conditions do not affect the size of generated relative peak power or the volume of work performed in pulsating anaerobic exercise. Results: In the first of five series of efforts performed with the lower limbs (LL) at an ambient temperature of 21 ☌, statistically significant differences ( p < 0.001) were found between the mean RPP values recorded during the first and third and fourth repetitions, and between the second versus third and fourth repetitions. In each sequence, subjects performed four anaerobic tests with the upper and lower limbs. Each sequence was followed by a 15 min interval for rest. The efforts differed from typical interval exercise by alternating upper- and lower-limb efforts, as well as with regard to the duration of those efforts. In the main part of the examinations, judo athletes performed five sequences (7.20 min each), alternating efforts on a leg cycle and arm cycle ergometer in a thermal chamber at 21 ± 0.5 ☌ and 31 ± 0.5 ☌. ![]() A complete set of results was obtained for 10 athletes. Methods: The study included 15 judo athletes aged 20.7 ± 2.0 years, with a body height of 178 ± 6.3 cm, body mass totalling 76.3 ± 12.6 kg, VO 2max at 43.2 ± 7.8 mL The main objective of the study was to determine changes in anaerobic total work (TW) and relative peak power (RPP) during a special judo fitness test at different ambient temperatures performed among judo athletes. When athletes compete in an elevated ambient temperature, metabolic processes in their bodies become intensified. Background: Thermoregulatory processes play an important role during athletic competition.
