The aim of this study was to analyse the temporal structure of individual tennis play on hard courts in adolescence. Thirty-two national-level tennis players (16 females, 16 males) participated in the study (age 15.6±0.9 years, weight 61.7±1.4 kg, height 1.70±0.14 m). All participants played an official competition on hard courts and with the same type of balls. Games were recorded for later analysis of total play time, real play time, and resting time, both in absolute values and as a percentage of total time. The average duration of a point and the number of strokes per rally were also determined. Results showed no differences based on gender, with a total play time of 105.00±20.00 min, real play time of 31.50±5.83 min, and resting time of 73.5±8.50 min. The ratio of work to resting time was 1:2.7, the number of strokes per rally was 5.12±0.17, and a point lasted an average of 9.08±0.60 s. Our results show the importance of keeping in mind the technical evolution of players at this age, with the goal of reaching maximum athletic performance. The adolescent players showed approximately the same number of strokes per rally, but with a greater average duration compared with adult elite athletes. Verf.-Referat
