Effects of Tennis Practice on the Coincidence Timing Accuracy of Adults and Children
Research Quarterly for Exercise and Sport, 1998
This study examines the development of perceptuo-motor processes involved in coincidence timing tasks according to age and experience in tennis. Tennis players and novices aged 7, 10, 13, and 23 were tested in a coincidence timing task which consisted of estimating the arrival of a simulated moving object on a target. The effect of three different motions were analyzed: constant velocity; constant acceleration; and constant deceleration. Results showed that timing accuracy improves mainly between the ages of 7 and 10, (2) tennis practice accelerates the development of timing accuracy, and (3) acceleration or deceleration of the moving stimulus had no effect on the timing accuracy of any of the tested groups, suggesting a continuous visual control of the trajectory. Theoretical implications for the development of perceptuo-motor processes involved in coincidence timing tasks are discussed.
The effect of aging and tennis playing on coincidence-timing accuracy
Journal of aging and physical activity, 2006
This study examined the effect of tennis playing on the coincidence timing (CT) of older adults. Young, younger-old and older-old (20-30, 60-69, and 70-79 years old, respectively) tennis players and nonplayers were asked to synchronize a simple response (pressing a button) with the arrival of a moving stimulus at a target. Results showed that the older tennis players responded with a slight bias similar to that of the young players. Two experiments were conducted to determine whether the elimination of age effects through tennis playing was a result of maintaining basic perceptuomotor and perceptual processes or of some possible compensation strategy. The results revealed that the age-related increase in the visuomotor delay was significantly correlated with CT performance in older nonplayers but not in older tennis players. These results suggest that playing tennis is beneficial to older adults, insofar as they remained as accurate as younger ones despite less efficient perceptuomo...
Exploring the coincidence anticipation timing among racket sports athletes
Journal of Sports Science and Nutrition, 2022
To compare the coincidence-anticipation time among different racquet sports. Methodology: A total of 30 male subjects were selected from badminton, tennis, and table tennis from Gwalior city, M.P.by using the purposive sampling technique. The age of the subjects ranged from 18 to 26 years and all were regular players with a good and sound level of skill. Coincidence-anticipation time was taken in this study as an I.V. (Independent Variable) and D.V. (Dependent Variable) were the players of all three sports respectively. The test was measured on the Bassin Anticipation Timer. Subjects were acknowledged about the test and its very functioning beforehand the test took place. All the subjects were given 5 initial trials before measuring the final best of two scores. The best score out of the two final trials was considered. The test was administered under the supervision of two research scholars and an expert to avoid the non-response error and to mitigate any confounding effects. Conclusion: From the evaluation of the test results on SPSS 25 by one-way analysis of variance and HSD Turkey for the post hoc test. It was found that male tennis players have shown a significant difference at a 0.05 level of significance.
Aging and Tennis Playing in a Coincidence-Timing Task With an Accelerating Object
Research Quarterly for Exercise and Sport, 2005
The purpose of the present study was to determine whether playing a specific ball sport, such as tennis, could maintain the coincidence-timing (CT) performance of older adults at a similar level to that of younger ones. To address this question, tennis players and nonplayers of three different age ranges (ages 20-30, 60-70, and 70-80 years) performed a simple CT task consisting of timing their response (pressing a button) to coincide with the arrival of a stimulus at a target. The stimulus moved at either an accelerating, constant, or decelerating velocity. As expected, all participants were affected by the velocity manipulation, which led to late and early responses to accelerating and decelerating stimuli, respectively. Whereas this response bias was increasingly pronounced with advancing age in nonplayers, no difference was found among player groups of different ages. Finally, we showed that the length of the visuomotor delay could explain the effect of nonconstant velocities.
Effect of expertise on coincident-timing accuracy in a fast ball game
Journal of Sports Sciences, 1997
The aim of this study was to examine the effect of intensive practice in table tennis on perceptual coincident timing. The main question was whether the perceptual demands encountered in fast ball sports produce m odi® cations of the perceptual visual system. Expert table tennis players and novices were compared in a perceptual task which consisted of estimating, by pressing a key, the arrival of a moving stimulus at a target. The stimulus, which was presented either at constant velocity or at constant deceleration, reproduced as closely as possible the natural visual dem ands encountered in table tennis. The difference between the time of response and the time of arrival of the stimulus at a target position was m easured over 40 trials for each of the 16 participants. The results showed no effect of expertise under the constant-velocity condition but an effect under the decelerative condition, indicating that experts were less trajectory-dependent than novices. This result was interpreted as re¯ecting a better adaptation of the perceptual system of experts to the constraints encountered during table tennis and speci® cally to the perceptual demands resulting from varied and decelerated ball trajectories. Finally, some limitations of the coincidence anticipation procedure are highlighted, concerning its use in practical settings for evaluating athletes or detecting sport talents, and the need for the simulation conditions during testing to reproduce as closely as possible the perceptual demands of real life is discussed.
Reliability and Accuracy of Ball Speed During Different Strokes in Young Tennis Players
Sports Medicine International Open, 2018
This study aimed to examine the relationship between anthropometric and sport level (SL) variables and both ball speed and accuracy in young male competitive tennis players. A secondary aim of this study was to analyze the possible differences in ball speed and accuracy between players of different competitive levels. A total of 85 players (age: 14.7±2.4 years; height: 1.65±0.12 m; body weight: 56.3±13.4 kg) were divided into five groups according to their positions in the ranking list. To measure stroke performances, the goal was to hit 20 balls at the maximum possible speed inside the court, with the opportunity of hitting a maximum of 30 balls for each groundstroke and 40 for serve. Accuracy was calculated by dividing the number of balls inside the default surface by the total number of hits. The ball speed showed high reliability for all three strokes assessed. The ball speed progressively increased as SL increased for all strokes, whereas accuracy remained unchanged across SL g...
THE EFFECT OF 8 WEEK TENNIS TECHNICAL TRAINING AND GAMES ON REACTION TIME IN 10-12 YEAR OLD BOYS
The aim of this study is to assess the effect of tennis technique training and games on reaction times of 10-12 years old boys. For this study, 40 subjects who did not perform any physical activity volunteered. Subjects randomly assigned two groups: Experimental group: 20, control group: 20. The experimental group was subjected to 8 week three days a week and 60 minute per session tennis and education with games training program modified according to relevant age group. The control group did not participate any physical activity. Visual, auditory and mix reaction times were measured by Newtest 1000 reaction timer. Subjects’ reaction times were measured twice before and after training program. SPSS 22.0 package program was used for analysis of the data obtained from the study. Independent Sample T test was used for comparison between groups, and paired samples t test was analyzed at p <0.05 significance level. As a result of the study, there was no difference in the control group, and after eight weeks of tenement-specific games and technical training, the research group revealed significant changes between auditory, visual and mixed reaction times in both hands.
Analysing time pressure in professional tennis
Journal of Sports Analytics
Taking advantage of space and time is a major focus of tennis coaching yet few statistical measures exist to evaluate a player's spatio-temporal performance in matches. The present study proposed the time to net as a single metric capturing both space and time characteristics of the quality of a shot. Tracking data from 2017 Australian Open allowed a detailed investigation of the characteristics and predictive value of the time-to-net in 33,913 men's and 19,195 women's shots. For groundstroke shots, the majority of men's and women's shots have a time-to-net between 200 and 800 ms. The expected time to net was found to vary significantly by gender, shot type, and where in a rally it occurred. We found considerable between-player differences in average time-to-net of groundstrokes when serving or receiving, indicating the potential for time-to-net to capture differences in playing style. Time-to-net increased prediction accuracy of point outcomes by 8 percentage points. These findings show that time to net is a simple spatio-temporal statistic that has descriptive and predictive value for performance analysis in tennis.

Background: the aim of the present study was to identify the temporal and notational performance differences between elite men’s and women’s badminton players according to match type and set. Methods: the sample was composed of 60 men’s and 60 women’s matches classified by match type or duration: short (lower quartile), long (upper quartile) and regular matches (interquartile range). Temporal and notational variables were analysed for each match and compared between sexes accounting for match duration. Results: greater intensity for most variables (i.e., rally time, rest time, density, and strokes per match/rally) was exhibited in men’s matches compared with women’s matches (i.e., higher frequency between strokes). In addition, the greater intensity for men compared to women was more pertinent during long matches (13 significant variables) and less evident during short matches (six significant variables). Point outcome displayed similar trends for each sex during matches with more w...
