Abstract

V originále

The aim of the study was to verify the influence of RAE in players of the World Junior Tennis Finals (WJTF) in 2012-2016 (n=240). They were grouped in three-member teams of individual countries, which means 48 players in the age 13-14 years took part each year. The research data (birth dates, results of WJTF matches) has been taken from the official tournament materials of the ITF. The data has been analyzed according to selected criteria (the whole observed period, individual years, semi-final matches, and ranking of players in team nominations). Verification of specific distribution was done by means of the Kolmogorov-Smirnov test (variations on goodness-of-fit) and the chi-squared test (variations on goodness-of-fit). A significant influence of RAE has been statistically proven in the whole sample (n=240) in the observed period 2012-2016 (x2 =108.6, p=0.00) and in individual years too. Asignificant influence of RAE has been proven in the players of the semi-final matches (x2 =42.06, p=0.00) in the whole observed period (2012–2016), however, it was lower than in the players of the whole observed sample. The influence of RAE has been proven in years 2012 (Dmax=0.51, CV=0.375) and 2016 (Dmax=0.59, CV=0.375) of semi-final matches in individual years. The influence of RAE has been proven according to the criterion ‘ranking of players in team nominations’ (1st, 2nd or 3rd player); the higher influence of RAE was observed in the first nominated players c2 =44.68, p=0.00) than in the second nominated players (x2 =38.14, p=0.00) or the third ones (x2 =29.37, p=0.00).
