Purpose: Little is known about the effect of sleep restriction (SR) on different domains of athletes’ physical performance. Therefore, the aim of this randomized, counterbalanced, and crossover study was to evaluate the effect of acute SR on sport-specific technical and athletic performance in male junior tennis players. Methods: Tennis players (N = 12; age 15.4 ± 2.6 y) were randomly allocated to either a sleep-restriction condition (SR, n = 6), where they experienced acute sleep restriction the night before the test session (≤5 h of sleep), or to a control condition (CON, n = 6), where they followed their habitual sleep–wake routines. Testing procedures included 20 left and right serves, 15 forehand and backhand crosscourt shots, and a repeated-sprint-ability test (RSA). The accuracy of serves and shots was considered for further analysis. One week later, players of SR joined CON, and players of CON experienced SR, and all test procedures were repeated. Results: Significant decrease in the accuracy of right (−17.5%, P = .010, effect size [ES] = 1.0, moderate) and left serve (−14.1%, P = .014, ES = 1.2, large), crosscourt backhand (−23.9%, P = .003, ES ≥ 2.0, very large), and forehand shot (−15.6%, P = .014, ES = 1.1, moderate) were observed in SR compared to CON, while RSA was similar in both conditions. Conclusion: Coaches and athletes at the team and individual level should be aware that 1 night of SR affects sport-specific but not athletic performance in tennis players.

<p>The Japan Tennis Association established the Tennis Field Test as a tool for aiding the development of effective coaching methods and improving the competitive achievements of individual elite tennis players. On the basis of such evaluations, specific coaching methods can be developed for individual tennis players. This study aims to evaluate the physical fitness and athletic performance of tennis players using the Tennis Field Test, and to compare these attributes between players of different ages and abilities. A total of 48 tennis players participated, of which 24 were junior players (including 15 regional representatives), and 24 were senior players (including 18 national representatives). The subjects were further subdivided into average and superior groups on the basis of their competitive achievements in regional or national tournaments. All subjects participated in the Tennis Field Test, which consists of the following six items: the number of sit-ups performed in 30 sec (an index of muscular endurance), the standing long jump distance (an index of leg power), the sit and reach test (an index of flexibility), the time taken to perform the spider run (an index of agility), the time taken to sprint 10 m (an index of speed), and the distance run in three minutes (an index of whole-body endurance capacity). In this study, the subjects’ sit and reach test data were not examined due to differences in the measurement methods used between junior and senior tennis players. Among the junior tennis players, the superior group performed faster in the spider run than the average group (p = 0.0011). Among the senior tennis players, the superior group achieved a longer mean distance during the three-minute run than the average group (p = 0.0223). The test results of the remaining items for both groups were relatively similar. This study suggests that competitive achievement is associated with agility among junior tennis players, and is associated with whole-body endurance capacity among senior tennis players.</p>

AbstractTennis is one of the most popular and widely played sports enjoyed by players of different age groups and genders as a profession as well as a mode of recreation. A novel method, PETTLEP imagery combines both conventional and non-conventional style of training of an athlete and improves one’s performance. This study aimed to analyze the tennis service performance of junior tennis players based on PETTLEP imagery training. Forty-four junior male tennis players (Mage=13.22 years, SD=0.42) were selected for the study. The investigator handed over the MIQ-R questionnaire to all the participants in which they scored 16 and above points as per previous research. The participants were equally divided (n=11) into three experimental groups (E1, E2, and E3) and a control group. The service performance outcomes of all the players were compared before and after a training session. The three experimental groups were assigned with service-specific training, service-specific training combined with PETTLEP imagery training, and PETTLEP imagery training alone, respectively, for three days per week for 12 weeks. They were tested on their service accuracy based on the International tennis number (ITN) manual on-court assessment test. The data were assessed for normality and analyzed using non-parametric methods to reveal main effects (each training method alone) as well as to calculate the combined effect of PETTLEP and service-specific training. Certain significant improvements in tennis service were observed with service-specific training alone. Though it marginally outperformed the PETTLEP imagery method, the most improved services were observed with both PETTLEP and service-specific training utilized together. This implies an additive effect when both methods are used together.

Broad Interest

In sport psychology, there is broad interest in cognitive factors that affect sport performance. The purpose of this research was to examine one such factor, self-talk, in competitive sport performance. Twenty-four junior tennis players were observed during tournament matches. Their observable self-talk, gestures, and match scores were recorded. Players also described their positive, negative, and other thoughts on a postmatch questionnaire. A descriptive analysis of the self-talk and gestures that occurred during competition was generated. It was found that negative self-talk was associated with losing and that players who reported believing in the utility of self-talk won more points than players who did not. These results suggest that self-talk influences competitive sport outcomes. The importance of "believing" in self-talk and the potential motivational and detrimental effects of negative self-talk on performance are discussed.

Practice Trials

When orientation of a horizontal spoon image varies to the left or right, instructions can map left and right keypresses to the tip or handle location. We conducted Experiment 1 to determine whether practice with an incompatible mapping of the salient tip transfers to a test session in which the relevant part and/or mapping are changed. Participants performed 80 practice trials with tip-incompatible mapping, followed by 80 test trials with tip-compatible, tip-incompatible, handle-compatible, or handle-incompatible mapping. Performance improved across 20-trial blocks in the practice session. In the test session, responses were 65-ms faster with tip-compatible than tip-incompatible mapping but 31-ms faster with handle-incompatible than handle-compatible mapping. This latter result, and verbal reports, indicate that some participants adopted a strategy of responding compatibly to the salient tip even though instructed to respond to the handle. Experiment 2 focused on whether participants with handle-incompatible mapping instructions would adopt the tip-compatible strategy spontaneously or after receiving a hint. 77% of participants reported adopting the tip-compatible strategy in session 1, showing that prior experience responding to the tip is not necessary. 9% of participants did not report using that strategy in session 1 but reported changing to it in session 2 after receiving the hint. Their responses in session 2 were slower than those who used the strategy throughout, but this difference was minimal in the last two trial blocks. Compatible mapping of the salient spoon tip to keypresses dominated performance over prior practice with incompatible tip mapping and instructions with incompatible handle mapping.
