“…Among the simplest and the most popular methods of influence on the athletes on the part of a coach in the process of enhancing their technical mastery one can single out verbal methods. (Diachkov, 1969;Lépine, 2012;Kolumbet at al., 2017). Verbal methods make up the cornerstone of all general methods of instruction and education.…”

The aim of the work -to examine the effect of teaching guidelines on cyclists pedalling techniques and to determine the most significant ones.Material and methods.The experiment involved 10 high qualification pursuit racers. The characteristics of efficient efforts applied by the racers to the bicycle cranks are veraciously connected to the rate of pedalling throughout the whole distance (r=0,713-0,922). By changing (through verbal guidelines) the parameters of efficient efforts in a pedalling cycle it is possible to control the speed in certain ways. The research into the interrelation between efficient efforts in the cycle of pedalling and the pedalling rate in the process of modelling an individual pursuit revealed two types of dependence between them.In case of the first type dependence the growth of efficient efforts values within a cycle leads to an increase in speed. In the second situation the increase in efficient efforts values is accompanied by a decrease in the rate of pedalling. The 2-d type dependence is irrational (from the point of efficiency) and requires correction. Conclusions. The intentional use of verbal acts positively affects the movement structure. The effective solution of movement tasks depends on the orientation of the athlete attention towards certain elements of the movement system. One should select those guidelines which are suitable for the specifics of the organization of the movement act system

Purpose:to determine the efficiency of the cyclist in various tactical options. Material:In the experiments participated athletes (n = 6) of high qualification (mean age -19.8 ± 1.3 years, mean weight -71.4 ± 3.5 kg). As a model of the individual pursuit race at 4 km, a five-minute pedaling on the bicycle ergometer was used. Series of loads was set on the modernized mechanical bicycle ergometer "Monark". The five-minute bicycle ergometer test is similar to the individual pursuit race at 4 km: according to the time of the exercise; on the frequency of pedaling (110-120 rpm); on the frequency of heartbeats. Results:Tactical variants in the pursuit race at 4 km are considered. The total work in a free test was on average 106.38 ± 3.57 kJ. The operating energy consumption is on average for 379.0±16.1 kJ. The operating efficiency (economy) of the exercise attained on average for 28.0 ± 0.75%. This corresponds to the effectiveness of aerobic work of moderate power. The ratio of aerobic and anaerobic contributions to the provision of work was 77.3 and 22.7%. The smallest work was done in a test with step-increasing power. The athletes performed the closest work to the given job in the test with a variable (±15%) operating mode. The shortfall in it was on average for 0.46%. The absence of reliable differences in the economics of the work did not allow us to identify a rational variant of power distribution for an exercise lasting 5 minutes. Conclusions:Tactical options in the pursuit race for 4 km depend on the features of the power systems of the rider. When optimizing tactics, it is necessary to select an individually optimal variant of the distribution of forces at a distance.

Purpose:to develop a system for monitoring the level of special preparedness of cyclists (specialized in individual race for 4 km) on the basis of the indicators of the cardiorespiratory system. Material:The study involved bicyclists (n=14, age 18-22 years). Results:The step-increasing load to the full allows to determine the maximum functional opportunities of the body of cyclists. The coefficient of efficiency of the functioning of the cardiovascular system is equal to the ratio of the average distance value of the pulse to the maximum value of the pulse. Using the linear regression equation, it is possible to predict the magnitude of the pulse at a given speed of movement. Conclusions:It is possible to find out the individual characteristics of athletes with the help of an indicator of the effectiveness of the functioning of the cardiovascular system. One can compare the activity of the cardiovascular system of athletes of different qualifications, different age groups, gender, level of preparedness. The degree of realization of the functionality of cyclists is calculated by a special formula and serves to monitor the training and competitive process. The results of the studies make it possible to predict the result by evaluating the level of special physical preparation.
