Assessment and control of athletes physical ability aged 6-8 in tennis. choosing and selecton framework

Introduction

Nowadays, tennis is gaining popularity and it is rapidly spread all over the world. Consequently, the need of teaching and learning the basic factors, which affect the dynamic development of the various selection levels, training and couching young tennis players in Greece, has been appeared.
Purpose
The research will elaborate the assessment framework for checking the general physical ability of children aged 6-8 after a two- year period of initial training in tennis (Hoem I. 1975).

Method

The aim of the research is the check of basic physical abilities as speed, endurance, and flexibility (Martin 1977), (Katsagolis 1992). The research is held in two periods. Each period lasts 20 months with a weekly three-hour program of 60 minutes each time. The sample of the research was consisted of 60 children (30 boys and 30 girls) aged 6-8, pupils of the first and the second class of primary school. The basic methodology was consisted of 6 tests which were divided in three categories. a) Speed: Test 1, 30 m running from up-right position, Test 2, 3x11m forwards- backwards. b) Endurance: Test 3, 55m running with direction changes, Test 4: 2min continuous deep sitting and standing. c) Flexibility: Test 5: Bending forward-down from up-right position, Test 6: passing the bar with two hands over and behind the head. For the statistical analysis of the results we used the variance analyze and sigmalen method of Martin. The basic idea of this method is the linear transformation of the registered numbered units / Xij / to physical numbers / Zij / using the results’ number average and their typical variations / Sj /. To the boys’ and girls’ results were used the a numbered width of 20 points with "Z" , "P" and "T" points with (X-+2S). (Blagush P.K 1982, Morrow James R 1995, Zatsiorski V.M 1982)

Results / Conclusions

All results of the 6 tests are appeared between 0-20 points with 98,57 % of the young tennis players having performed within these limits. 1,43 % are outside the above limits (20< or 1>) and 0,81% were not credit at all. All the testing basic variables give us the possibility of an individual and complete grading: a) for the selection of children for tennis in schools and b) for the evaluation and checking of the athletes’ physical preparation in tennis within the framework of training and selection. For the general grading we use Wi=Σ Tij / n; where Wi is the general grading of the tests data, Tij is the assessed individual grading of the tennis player /j/ in tests, n is the number of tests.
PRACTICAL GRADING SELECTION:
No 1: R=5,40S, T=16p. No 4: R=24P, T=5p.
No 2: R=8.89S, T=19p. No 5: R=110Cm, T=20p.
No 3: R=17,20S, T=7p. No 6: R=66Cm, T=19p.
Wi=(16 +19+7+5+20+19):6=14,3p.
From the above results we conclude that the athlete has to give attention to the dynamic development of the endurance of the lower body (No 3: T=7p., No 4:T=5p.).
The empirical checking of the tennis players in the initial training stage and the proposed basic grading for a qualitative checking of their physical ability give us the opportunity for an objective selection of the young tennis players (Better learning age in childhood, Meinel 1966), (Katsagolis, 1992), which are varied on the basis of the temporary scientific demands in sports.
