Training of Tourists-Skiers in the Conditions of Short-Term Winter.

Ріст конкуренції в змаганнях із лижного туризму висуває сьогодні більш високі вимоги до підготовки лижників-туристів в умовах короткочасної зими. У дослідженні проаналізовано та узагальнено компоненти підготовки лижників-туристів в умовах короткочасної зими. Методика їхньої підготовки в таких умовах має свою специфіку. Підготовчий період більш тривалий. Процес технічної підготовки повинен містити різноманітні спеціально-підготовчі вправи з використанням тренажерів, які дають змогу підвищувати рівень спеціальної фізичної та технічної підготовленості туриста-лижника. Спеціально-підготовчі засоби лижної підготовки включають підвідні й імітаційні вправи, які допомагають не тільки опанувати техніку способів пересування на лижах, але й значно підвищити рівень спеціальної фізичної підготовленості. Виконання імітаційних вправ у русі значно підвищує фізичне навантаження. Частину спеціально-підготовчих вправ можна виконувати з використанням тренажерів. До них належать гумові та блокові амортизатори, ізокінетичні тренажери. Ефективним засобом технічної підготовки є лижеролери. Зі всіх спеціально-підготовчих вправ лижника лише техніка пересування на лижеролерах має періоди кочення ідентичні періодам ковзання лиж по снігу. Оптимізація техніки й тактики в змаганнях із лижного туризму може здійснюватися вибором кращого з можливих способів пересування на лижах кожним відрізком дистанції за критеріями швидкості та економічності, з урахуванням крутизни схилу й умов ковзання. Що більшим арсеналом техніки та технічних прийомів користується кожен турист-лижник, то кращою й більш узгодженою буде робота команди. Окрім цього, запропоновано оптимізувати тактико-технічні можливості команди, більш ефективно застосовуючи сучасний інвентар і спорядження. Ключові слова: туристи-лижники, технічна підготовка, спеціальні засоби підготовки, тренажери. The growth of competitiveness in skiing tourism requires higher demands towards the training of tourists-skiers in the conditions of short-term winter. The task of the research − to analyze and generalize the components of the training in short-term winter. The methods of the training of tourists-skiers in the conditions of short-term winter has its specific features. The preparatory period is the longer one. The process of technical training should include various special- preparatory exercises with the usage of simulators, which allow to increase the level of special physical and technical preparedness of a tourist-skier. Special-preparatory exercises of ski training include preliminary and imitative exercises,which help not only to acquire necessary technique of means of ski conveyance, but to improve the level of special physical preparedness significantly. The fulfillment of imitative exercises in motion increases physical loading meaningfully. Some special-preparatory exercises may be performed with the usage of simulators. They include rubber and block absorbers, as well as isokinetic exercise equipment. The effective means of technical training are roller skis. Of all the special-preparatory exercises of a skier only the technique of movement by means of roller skis has rental periods, identical to the periods of ski gliding over the snow. The optimization of techniques and tactics in competitive ski touring can be done by selecting the best possible ways of ski moving on every segment of distance according to speed and efficiency criteria, taking into account steepness of the rise and slip conditions. The more techniques and technical means are used by every tourist-skier, the better and more coordinated the work of a team will be. Furthermore, the author suggests to optimize tactical-and-technical capabilities of a team by more effective usage of modern inventory and equipment

EXPERIENCE IN USING TENOTEN IN THE TREATMENT OF TICK HYPERKINESIS IN CHILDREN

The clinical efficacy of tenoten (pediatric formulation) was comparatively studied in children with tick hyperkinesis. One hundred and thirty children (34 girls and 96 boys) aged 3 to 5 years were examined. The drug of comparison was persen in local ticks and fenibut in generalized ticks. An attempt was also undertaken to treat patients with generalized ticks (Tourette's syndrome), by using tenoten (pediatric formulation). As shown by the results of the study, tenoten (pediatric formulation) is most effective in local ticks. In generalized hyperkinesis, tenoten is as effective as fenibut and the former is, in some cases, superior to the latter. Monotherapy with tenoten (pediatric formulation) is insufficiently effective in Tourette's syndrome. Tenoten (pediatric formulation) has been also shown to diminish anxiety and to have a positive effect on the biological activity of the brain. The agent is safe and there have been no adverse reactions due to its use

Pediatric Tenoten in therapy of childhood nocturnal enuresis

Objective: to study the efficacy of pediatric Tenoten in the treatment of secondary nocturnal enuresis in children. Subjects and methods. A comparative randomized study of the results of treatment was conducted in 36 children aged 5 to 15 years with secondary enuresis, who received pediatric Tenoten (n = 18; Group 1) and fenibut (n = 18; Group 2). Tenoten (pediatric formulation) was given a sublingual tablet thrice daily for 2 months. Therapeutic effectiveness was evaluated by clinical parameters (the number of nocturnal enuresis episodes per month and anxiety scale scores). Results. There was a significant reduction or complete cessation of nocturnal enuresis episodes in the majority of children and a decrease in anxiety levels. Positive clinical changes were accompanied by a trend toward normalization of spectral coherent EEG characteristics. Conclusion. Treatment with pediatric Tenoten results in a reduction in the rate of nocturnal enuresis episodes and, in some cases, in their cessation, positively affects the psychological status of children, and improves the indicators of brain bioelectrical activity. The drug causes no adverse reactions and is well tolerated

The Irrecoverable Loss in Sleep on Weekdays of Two Distinct Chronotypes Can Be Equalized by Permitting a >2 h Difference in Waking Time

Background: Our work/study culture is biased towards the circadian clocks of “morning types”, whereas “evening types” are forced to advance their weekday waking times relative to weekend waking times. Since the experimental research consistently reveals a >2 h difference between these two chronotypes in the positions of their endogenous circadian phases, we hypothesized the necessity to permit a >2 h difference between them in weekday waking times to equalize their irrecoverable loss in sleep on weekdays. Methods: A total of 659 and 1106 participants of online surveys identified themselves as morning and evening types, respectively. The hypothesis was tested by applying a model of sleep–wake regulation for simulating sleep times reported by 245 lecturers of these two types, and by comparison of sleep times of these types among these lecturers and 1520 students. Results: The hypothesis was supported by results showing that, if, on weekdays, an “average” morning type wakes at 6 a.m., the equalization of the weekday sleep loss of the two chronotypes would require the waking time of an “average” evening type to be no earlier than 8 a.m. Conclusions: These results may be implemented in a model-based methodology for the correction of weekday waking times to equalize weekday sleep loss
