Physical exercise has been shown to be an important modulator of the antioxidant system and neuroprotective in several diseases and treatments that affect the central nervous system. In this sense, the present study aimed to evaluate the effect of physical exercise in dynamic balance, motor coordination, exploratory locomotor activity and in the oxidative and immunological balance of rats treated with vincristine (VCR). For that, 40 adult rats were divided into two groups: exercise group (6 weeks of swimming, 1h/day, 5 days/week, with overload of 5% of body weight) and sedentary group. After training, rats were treated with 0.5 mg/kg of vincristine sulfate for two weeks or with the same dose of 0.9% NaCl. The behavioral tests were conducted 1 and 7 days after each dose of VCR. On day 15 we carried out the biochemical analyzes of the cerebellum. The physical exercise was able to protect against the loss of dynamic balance and motor coordination and, had effect per se in the exploratory locomotor activity, and neutralize oxidative stress, damage DNA and immune damage caused by VCR up to 15 days after the end of the training protocol. In conclusion, we observed that previous physical training protects of the damage motor induced by vincristine.Key-words: exercise, oxidative stress, neuroprotection, cerebellum.

The aim. The karate competition requires the athlete to have a comprehensive manifestation of motor abilities. At the same time, the motor-related area is closely connected with function of the auditory analyzer. Consequently, auditory deprivation affects all types of motor abilities, but, first of all, it affects coordination abilities, since they are implemented on a defective basis of the sensory systems involved in controlling movements. Technical means (punches and kicks, blocks) and tactical means (instant assessment of the situation and making the right decisions) of traditional karate effectively affect the correction of various manifestations of motor coordination. Moreover, the above mentioned karate means affect motor coordination through motor experience in the form of complicating previously mastered movements and mastering new movements with increased coordination difficulties. Methods and organization of the study. We used the following set of complementary theoretical methods to meet the challenge of theoretical substantiation of the research: analysis of psychological, pedagogical and methodical literature, scientific articles on adaptive physical culture, abstracting, generalization and concretization. Results. The research revealed the most common deviations in the manifestation of various components of coordination abilities of children with auditory deprivation. We specified sensitive periods of development of this type of motor qualities in children with hearing impairments. We identified basic karate techniques and actions, which favorably influence the course of development of coordination abilities. Conclusion. Correction and development of the coordination abilities of children with hearing impairments represent the primary task of adaptive physical education. The most favorable age is primary school age. Techniques and actions of traditional karate have a high potential of effective impact on all types of coordination abilities of children.
