Abstract Resume

Background: Tennis requires great variety of movements during a match that can extend for a few hours. However, the length of matches may depend on the utilized floor, the training
level or characteristics of athletes. Objective: To characterize the internal and external training load during a field tennis match in adolescent athletes.
Methods: Ten tennis players (15.5 ± 0.4 years old, 1.70 ± 0.02 meters, 61.9 ± 2.21 kg) unranked in the São Paulo State Federation participated in the study. It was simulated a field
tennis game for 90 minutes. The internal load was determined from the heart rate (HR), blood lactate (BL) and rating of perceived exertion (RPE), analyzed at rest (10 minutes), during the simulation
of a match (every 30 minutes) and assists recovery (10 minutes). The external load was determined by the duration of the rally, quantity balls for points and length of intervals between points,
measured from the video analysis every 30 minutes. The data are described as mean and standard error. Analysis of variance (one way ANOVA) with Bonferroni correction was used to determine the degree
of variation of internal and external load at different times of collections of data.
Results: HR and RPE showed similar behavior, increasing and stabilizing their values during the game and significantly reducing the recovery. The lactate did not change significantly
in any of the analyzes. The duration of the rally showed no significant differences during match (0-30 min = 6.2 ± 0,4s); (30 to 60 min = 6.6 ± 0.3 s); (60 to 90 min = 6.0 ± 0.3 s). The quantity of
balls during the points showed no significant differences during the match (0-30 min = 4.0 ± 0.2); (30 to 60 min = 4.4 ± 0.2); (60 to 90 min = 4.0 ± 0.2). The rest between the points did not differ
during the game (0-30 min = 17.8 ± 0.8); (30 to 60 = 17.9 ± 0.6 min); (60 to 90 = 18.1 ± 0.7 min).
Conclusions: The characterization of the requirement imposed on athletes from internal and external loads, during the 90-minute simulated game, allows us to understand the
intermittent feature of the field of tennis, leading to young athletes one effort-pause ratio of approximately 1:3 seconds respectively, and small variations in physiological parameters during the
