La muestra estuvo compuesta por 108 jugadores federados de pádel (edad media = 33.81 ± 6.72 años). Se analizaron, a través de observación sistemática con el sistema SAGIT, un total 4406 puntos correspondientes a 27 partidos de pádel. Los partidos fueron divididos en tres niveles de compe…
Ball Impact Position in Recreational Male Padel Players: Implications for Training and Injury Management
2021
Racket sports such as padel are characterized by the repetition of unilateral gestures, which can lead to negative adaptations like asymmetries or overuse musculoskeletal injuries. The purpose of this study was to determine the differences in ball impact positions (i.e., forward or backward of the center of gravity) in nine stroke types in a sample of forty-eight recreational male padel players. The sample included 14,478 shots corresponding to 18 matches from six tournaments. Forty-eight male padel players were classified into two groups according to their level: trained (n = 24) and novice (n = 24). Type of stroke and ball impact position were registered using a computerized motion tracki…

Comparison of distance covered in paddle in the serve team according to performance level
2013
Although paddle is the second most practiced sport in Spain, the scientific knowledge about the players' work-load is still very low. The serve is a critical situation because the team has the opportunity to start the point attacking by approaching the net straight after the serve. However, the distance covered by the serve team still has not been studied in padel. OBJECTIVE: This study aimed to analyse the distance covered by the serve team according performance level. It was hypothesized that the server would cover more distance than his partner due to the approach to the net after the serve. Moreover, it also was hypothesized that the difference between serve and partner would be greater…
Challenging serve myths in doubles tennis
2021
Doubles tennis has received little interest from quantitative research to date. Coach-led anecdotes therefore abound. The aims of this study were therefore to evaluate the veracity of the following common anecdotes: (a) serving teams have an advantage regardless of the length of the point; (b) serving teams have a greater advantage with new balls; (c) regular teams perform better when serving than new teams and (d) serving teams decrease their performance during break points. Data from doubles hard-court and clay-court tennis were collated for 52 doubles teams during 2018 ATP tournaments. Results revealed that the advantage of serving teams was evident on the points lasting up to 4 shots. …
Fitness testing in tennis: Influence of anthropometric characteristics, physical performance, and functional test on serve velocity in professional p…
2021
The aims of this study were to examine the relationship between anthropometric variables, physical performance, and functional test with serve velocity regarding tennis players’ level and to design regression models that effectively predict serve velocity. A sample of sixteen male tennis players participated in this study (national level = 8, professional level = 7). Anthropometric measurements (body mass, height, body mass index and body segments) and physical test (hand strength, countermovement jump, jump on serve, and serve velocity) and functional test (medicine ball throw overhead and shot put) were performed. No differences in anthropometrics and physical test were found between nati…

The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis
2013
Martinez-Gallego R, Guzman JF, James N, Ramon-Llin J, Crespo M, Vuckovic G. The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S601-S607, 2013. Winners and errors have been two of the most studied performance indicators in tennis, contributing to the prediction of match outcome and definition of the playing style of the players. Furthermore, the position occupied by the player on the court has also been shown to be a good indicator of both the final result and style of play. The aim of this study was to examine whether there were differences between game winners and losers i…
The Effect of the Return of Serve on the Server Pair’s Movement Parameters and Rally Outcome in Padel Using Cluster Analysis
2019
Purpose: The pressure exerted on racket sports players by the service has been well documented. Whilst the return of serve has been suggested through qualitative interviews as being of similar importance there is a dearth of quantitative data to support this contention. This study analyzed time, speed, and distance parameters related to the outcome of the return of serve (ROS) in Padel, a sport similar to tennis but played on a court bounded by walls and played in doubles format only. Methods: Matches (n = 18) at two tournaments, sanctioned by the Valencian Federation, in 2012 were recorded and processed using Tracker software. ROS shot type (flat or lob), ball location, players’ positions …

Differences in kinematic and match-play demands between elite winning and losing wheelchair padel players
2020
We aimed to compare the match-play and kinematic demands of the translation and rotation movements of elite wheelchair padel players as a function of match results. Twenty-two elite male players were video-analysed with a two-dimensional direct linear transformation (DLT) -corrected video system across seven matches of a professional tournament. Distance, turns, changes of direction, linear and angular speed, acceleration and the players’ heart rate (HR) were recorded. Losing couples in wheelchair padel covered greater distances than winners (P <0.001; r = 0.024) and did so at a higher speed (P <0.001; r = 0.06), while making greater efforts by accelerating (P <0.001; ∅ = -0.021), braking (…
