The structure of tournament micro-cycle of junior tennis players of 15-16 years old

Actuality. Leading specialists in the sphere of sport preparation Ozolin, Matveev, Platonov, have proved that the process of training management is based on tournament activity. Specifically it accounts for work-out planning , the choice of means and methods for training, magnitudes of executed physical loads. In order to plan and carry out a training process most effectively it is necessary to know the magnitude of tournament loads, as well as the distribution of loads of different intensity among days of tournament micro cycles. Nowadays professional tennis payers are younger than in the past , in the world ranking there are players of 17 -18 yeas old. In the light of this the problem of earlier sport specialization arises. In order to gain high goals in the sport of greatest achievements, juniors of 15 – 16 years have to play at the level close to professional. It may be possible only if scientifically based system of planning and control of tournament and training loads are carried out.

Aim of work.Calculate the structure of tournament micro-cycles of juniors of 15 -16 years old.
Research tasks:
1) Measure out the duration of tournament micro-cycles, quantity of play days in them.
2) Find out parameters of tournament loads:
a) Parameters of external and internal aspects of exertion, exactly the volume and intensity;
b) Magnitude of tournament loads;
3) Find out the distribution of different magnitude exertions among days of tournament micro cycles.

Research methods. Analysis of literary sources, pedagogical observation and survey of tournament activity of youths of 15 -16 years old with the help of stenograph for taking down tournament actions of the player and хрнометрирования, pulse rate, субтест метода «миокинетическая psychodiagnostics» - offered by Mire –i- Lopes.

The results were analyzed with the help of methods of mathematical statistics.
Research results. We found out:
1) The duration of tournament micro-cycles, quantity of play days in them.
2) Parameters of tournament loads:
a) - Indices of external aspect of load of competitive matches.
Volume - match duration, pure ―time‖ of the game during a match, the sum of played points and sum of fulfilled hits.
Intensity - rate/tempo of played points, motor density of the matches.
- Indices of internal aspect of load of competitive matches.
Volume - sum of heartbeats during the match .
Intensity - minimum, maximum frequencies of heartbeats, that can be observedin the course of match. Also we registered average indices of heartbeats duringmatches and performance with different rate of intensity.
b) Magnitude of tournament loads.
3) Variants distribution of different magnitude exertions among days oftournament micro cycles (pictures 1, 2, 3).
