This study aimed to analyse the influence of the “no-ad scoring” or “gold point” rule on performance in professional padel, observing the differences between winners and losers, as well as between ...gender, game rounds and sets. For this, all the quarter-final, semi-final and final matches were analyzed, both in the male category (n = 100) and female (n = 74) of 15 tournaments of the World Padel Tour circuit in 2021. A total of 838 “gold points” were analyzed. The results show a higher percentage of games with gold points are played in women's padel than in men's padel (28.19 ± 9.24% vs 23.48 ± 10.51%; p<.001), with differences depending on the game round and the match set (p=.001). Winner pairs score significantly more gold points than losing pairs, both male (3.17±1.79 vs 2.24±1.87) and female (4.01±2.01 vs 2.54±1.72). Additionally, female winning pairs win significantly (p <.05) more gold points than male winning pairs. In conclusion, winning the gold point may be a key factor of performance in padel. In female players more differences are observed between winning and losing couples. In addition, in women's padel there is greater equality in the games score, due to the higher % of games with gold points. However, as the rounds progress, the men's padel is more equal even with respect to the score of the set, due to a higher number of games played, especially in the semifinals and final.
El objetivo de este estudio fue analizar la influencia de la regla del punto de oro en el rendimiento en pádel profesional, observando las posibles diferencias existentes entre ganadores y perdedores, así como entre género, rondas de juego y sets. Para ello, se analizaron todos los partidos de cuartos de final, semifinales y finales, tanto en categoría masculina (n=100), como femenina (n= 74) de 15 torneos del circuito World Padel Tour de 2021, con un total de 838 puntos de oro. Los resultados muestran que en el pádel femenino se disputan un mayor porcentaje de juegos con puntos de oro que en pádel masculino (28.19±9.24% vs 23.48±10.51%; p<.001), existiendo diferencias según la ronda de juego y el set del partido (p=.001). Las parejas ganadoras consiguen significativamente más puntos de oro ganados que las perdedoras, tanto en masculino (3.17±1.79 vs 2.24±1.87) como en femenino (4.01±2.01 vs 2.54±1.72). Además, las parejas ganadoras femeninas ganan significativamente (p<.05) más puntos de oro que las masculinas. En conclusión, ganar el punto de oro parece ser un factor de rendimiento en pádel, existiendo mayores diferencias en el género femenino entre ganadores y perdedores. Además, el mayor % de juegos con puntos de oro en pádel femenino indica una mayor igualdad en el juego. Sin embargo, a medida que avanzan las rondas, el pádel masculino es más igualado respecto al marcador del set, por un mayor número de juegos disputados, sobre todo en semifinales y final.
QE is the final ocular fixation that precedes critical athletic movements and that enables athletes to gather relevant information and organize their subsequent movement. Although little is known ...about the factors sustaining performance in table tennis, to date there has been no investigation to assess QE as a contributor to table tennis performance. Furthermore, there is limited research regarding the influence on QE of factors that are known to impact performance, such as task complexity and fatigue. In a within-subjects experimental design, we manipulated fatigue (high vs low) and task complexity (high vs low). Eleven elite table tennis players (m

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 (
= 24) and novice (
= 24). Type of stroke and ball impact position were registered using a computerized motion tracking video system. The ball impact position was computed from the distance (cm) between the coordinates of the ball and the player's center of gravity. Results show that trained players hit the ball in a more backward position (from 11 to 25 cm, compared to novice) in serve and offensive strokes (volleys, trays, and smashes) but used more forward strokes (from 7 to 32 cm, compared to novice) in defensive shots (groundstrokes, wall strokes, and lobs). Because the current differential variables are trainable and demonstrated to be of relevance for performance, the findings of this study may assist padel coaches in designing proper training plans to improve effectiveness and to prevent musculoskeletal injuries regarding the type of stroke and ball impact position. Such knowledge may constitute a very important factor affecting technique, biomechanics, and injury management in padel players of different competitive levels.
In this study, balance performance, agility, eye-hand coordination, and sports performance were compared between amateur badminton players and active controls.Thirty young adult badminton players and ...33 active controls participated in the study. Static single-leg standing balance (with eyes closed) was measured using a force platform, and dynamic balance was measured using the Y Balance Test (lower quarter). Agility was measured using a hexagon agility test, and eye-hand coordination was measured using a computerized finger-pointing task. Sports performance was quantified by the number of times a shuttlecock fell in a designated area following a badminton serve.The badminton players had superior accuracy in badminton serving (P < .001) relative to the active controls. However, no significant between-group differences were noted in all other outcome variables (P > .05).Amateur badminton players had more favorable sports performance, but not balance performance, agility, or eye-hand coordination, than controls.

In table tennis, many different approaches to scientific founded match analysis have been developed since the first ones in the 1960s. The aim of this paper is to give a review on some of the most ...acknowledged methods of match analysis in table tennis. The first chapter presents a historical overview of match analysis from all over the world. The second part reviews different approaches to match analysis in more detail, using the performance analysis classification of theoretical and practical performance analysis. The review includes the most actual theoretical performance analysis techniques in table tennis: performance indices, simulative approaches, momentum analysis, footwork analysis, and finally an approach which uses top expert knowledge for a comprehensive technical-tactical analysis. In the section of practical performance analysis, the paper presents two "best practice" examples describing performance analysis procedures of the two most successful countries of the last Olympics: China and Japan. The paper ends with a summary on the impact of the different approaches and gives an outlook on promising new developments.
Purpose: Identifying the magnitude of ball rotation is critical to reduce response time, aiming to improve table tennis performance. This study analyzed the influence of auditory and visual ...information on the perception accuracy and counterattack performance of table tennis players. Methods: Twenty-two high-level table tennis players (22.5 ± 6.1 years, 71.2 ± 9.8 kg, 173.5 ± 7.7 cm) performed two tasks. In the first task, the athletes analyzed audio and video files of the forehand movement on a computer screen with auditory, visual, and combined information and, as soon as possible, chose the ball spin type on a keyboard: fast (spinning ball forward at 140 rotations per second (rotations/s); medium (105 rotations/s); slow (84 rotations/s); or flat hit (70 rotations/s). In the second task, the athletes performed 80 counterattacks (forehand movement) at the table on a target (68x38 cm) with and without auditory information. Results: Friedman's ANOVA revealed a significant effect of condition for perception accuracy (p < .001). Post hoc tests showed higher perception accuracy in the combined and visual conditions. ANOVA also revealed a significant effect of condition for response time to perceive ball rotation (p < .001). The response time was shorter in the combined condition than the other conditions for all spin types. Kendall's analyses showed no significant correlations between perception accuracy and response time in any ball spin type. Regarding the counterattack performance, the Wilcoxon signed-rank test indicated higher performance when auditory information was available (p = .022). Conclusions: As auditory information influences the response time and counterattack performance, it seems crucial for trainers and athletes to explore and include auditory perception training methods.
Conventional racket sports training highly relies on coaches' knowledge and experience, leading to biases in the guidance. To solve this problem, smart wearable devices based on Internet of Things ...technology (IoT) have been extensively investigated to support data-driven training. Considerable studies introduced methods to extract valuable information from the sensor data collected by IoT devices. However, the information cannot provide actionable insights for coaches due to the large data volume and high data dimensions. We proposed an IoT + VA framework, Tac-Trainer, to integrate the sensor data, the information, and coaches' knowledge to facilitate racket sports training. Tac-Trainer consists of four components: device configuration, data interpretation, training optimization, and result visualization. These components collect trainees' kinematic data through IoT devices, transform the data into attributes and indicators, generate training suggestions, and provide an interactive visualization interface for exploration, respectively. We further discuss new research opportunities and challenges inspired by our work from two perspectives, VA for IoT and IoT for VA.
To quantify match load associated with padel and compare responses with both singles and doubles tennis.
On separate days, 12 participants (7 men and 5 women) played 60-minute padel (PADEL), singles ...tennis (SINGLES), and doubles tennis (DOUBLES) simulated games. Participants wore a 10-Hz GPS/100-Hz triaxial accelerometer unit and heart-rate monitor. Exercise-related sensations and blood lactate concentration were monitored every 20 minutes. Match-play characteristics (temporal structure) and shot selection were derived from video analysis. Vertical jump ability was assessed before and after each game.
Heart rate, exercise-related sensations (overall perceived exertion and limb discomfort), and physical load (total distance covered, PlayerLoad, acceleration density and load) for SINGLES were higher compared with DOUBLES and PADEL (all P ≤ .05). Blood lactate concentrations remained low (1-2 mmol·L-1) and did not differ between conditions. Effective playing time (P < .001) was lower in SINGLES and DOUBLES compared with PADEL. The number of forehands (P = .002) and backhands (P < .001) was greater for SINGLES than for DOUBLES and PADEL. The number of volleys/smashes and lobs (P < .05) was greater for PADEL compared with SINGLES and DOUBLES. Performance for squat, countermovement, and multirebound jumps was similarly reduced below baseline after match play (P < .05), independent of condition.
Padel imposes a unique match load on players that is different from singles tennis and more closely resembles that of doubles tennis. Cardiovascular stimulation and physical load are highest in singles tennis, while padel sees players hit a larger variety of shots with higher effective playing percentages.
Purpose: Jigsaw is a popular cooperative method, but its effect on students' motivation in physical education (PE) remains uncertain. The purpose of this study was to estimate this Jigsaw effect and ...to explore whether the type of sport taught in PE modified this effect. Method: Overall, 136 middle-school students participated in two PE sequences in Jigsaw or control conditions, one in gymnastics and one in racket sports. These two types of sports were selected because they are frequently taught in PE and for their opposing characteristics. Students' motivation was estimated during the third and sixth lessons of each sequence with a subjective measure, that is, situational interest; moderate to vigorous physical activity was added as an objective measure related to motivation. Results: Compared to control conditions, Jigsaw progressively enhanced moderate to vigorous physical activity and the novelty dimension of situational interest in gymnastics, whereas it undermined moderate to vigorous physical activity and the challenge dimension of situational interest in rackets. Discussion: We discuss the decisive role of the type of sport according to their characteristics when implementing Jigsaw.
Serve and return of the serve are among the most critical technical-tactical factors influencing performance in table tennis (TT). The present study aimed to analyse sex differences in the spatial ...distribution of serve and serve-return in elite TT players. A total of 48 elite TT players (men:
n
= 24; women:
n
= 24) participated in the investigation. A total of 24 matches were recorded and examined, analysing 1,177 plays and 5,319 strokes in the men’s competition and 950 games and 5,097 strokes in the women’s competition. Technical actions were analysed using an observation tool validated by two expert TT coach with a high level of agreement (
K
> 0.80). Men distributed their serves over zones 1 and 2 of the table, while women more frequently selected zone 5 (
p
< 0.05). In men, 30.1% of the serves were near the net, 63.6% in the middle zone of the table and 6.2% in the end zone of the table, while in women, these values were 10.9%, 67.2%, and 21.8%, respectively. As for the technique of the serve-return depending on the zone of the service, in men the action of the cut from zone 1 and 2 predominated, while in women this technique was more frequent from zone 5 (
p
< 0.05). On the other hand, the serve-return with the flip technique in zone 1, 3 and 4 was more frequent in men (
p
< 0.05). As for the return of the serve with the topspin technique, there were differences in zone 3, being more frequent in men (
p
< 0.05). Finally, the serve return with cut and defensive serve-return techniques in zones 3, 4, 5, and 6 were more frequent in women (
p
< 0.05). There are differences between sexes in service and return of serve actions during a match in elite players.
