Sports technology enhances athletes’ performance by providing feedback. However, interaction techniques of current devices may overwhelm athletes with excessive information or distract them from their performance. Despite previous research, design knowledge on how to interact with these devices to prevent such occasions are scarce. To address this gap, we introduce subtle displays as real-time sports performance feedback output devices that unobtrusively present low-resolution information. In this paper, we conceptualize and apply subtle displays to tennis by designing Tactowel, a texture changing sports towel. We evaluate Tactowel through a remote user study with 8 professional tennis players, in which they experience, compare and discuss Tactowel. Our results suggest subtle displays could prevent overwhelming and distracting athletes through three distinct design strategies: (1) Restricting the use excluding duration of performance, (2) using the available routines and interactions, and (3) giving an overall abstraction through tangible interaction. We discuss these results to present design implications and future considerations for designing subtle displays.

One’s perceived competence relates to participation and effort and can vary depending on the self-evaluation sources that athletes value. Ruble and Frey (1991) theorized that phase of skill development may affect one’s preference for different sorts of competence information. The present study tested Ruble and Frey’s model using a sample of 466 adult tennis players. Skill level was athletes’ United States Tennis Association rating. Participants rated the personal importance of tennis and the importance of different sources of self-assessment information. Results showed that beginners were more likely to value temporal comparisons, and advanced players were more likely to value social comparisons. Players rating tennis as highly important were more likely to value temporal comparisons and effort for self-assessment. The findings support Ruble and Frey’s model.

The purpose of this study was to examine the intensity of competitive trait anxiety and self-confidence and interpret whether these symptoms facilitated or debilitated performance in three distinct skill-level groups in tennis for both males and females. Advanced (n = 50), intermediate (n = 96), and novice (n = 79) tennis players completed a modified Competitive State Anxiety Inventory-2. The three groups did not differ for somatic anxiety intensity, but the novice group reported less cognitive anxiety intensity and the advanced group higher self-confidence levels. Only advanced players reported more facilitative interpretations versus the hypothesized progressive increase across skill level. Males and females did not differ on self-confidence and anxiety intensity, but males reported a more facilitative interpretation of anxiety. Analyses of subjects who reported debilitating effects for cognitive and somatic anxiety revealed higher intensities on both anxiety subscales and lower self-confidence levels. The discussion addresses implications for the practitioner.

The present study aimed to examine the effect of an 8-week balance training on the agility, strength, balance performance and tennis skills of tennis players aged 10-14. The study was participated by 19 tennis players (10 males and 9 females) playing in the EA Tennis Academy. The participants were selected randomly and divided into two groups as experimental group (9 players) and the control groups (10 players). Firstly, vertical jump, pro-agility, dynamic balance and ITN tennis skills tests were applied to all the participants. After all the test were completed, the experimental group were applied 8 weeks of balance and tennis training while the players in the control group continued tennis training only. The same tests were applied to the participants at the end of the 8 weeks. The findings of the study showed statistically significant improvement in the agility, balance index and tennis skills tests in the pre-test and post-tests of the experimental group (p = 0.034, p = 0.025, p = 0.003), whereas improvement was seen only in the tennis skills test of the control group (p = 0.000). In addition, no statistically significant difference was found in the vertical jump performance used to determine the explosive strength both in the experimental and control groups. As for the difference between groups, a significant difference was found only in the pro-agility post-tests of the experimental and control groups (p < 0.05). Based on these findings, it was revealed that balance training would improve agility and balance in 10-14 year-old children as well as contributing to their tennis skills. Therefore, it is considered that balance training should be included in training plans.

Several studies have indicated that musculoskeletal injuries are common during a professional tennis competition. However, data from a tropical country like Indonesia is lacking. This study aimed to obtain the incidence rate and injury characteristics and identify risk factors of musculoskeletal injuries among professional tennis players competing in Indonesia under the International Tennis Federation (ITF). The study was a prospective cohort during professional tennis tournaments in Jakarta, Indonesia in 2019, consisting of the ITF Women’s Circuit Indonesia (two weeks) and ITF Men’s Future Indonesia (three weeks). All athletes were enrolled in this study. Injuries were assessed based on the ITF Consensus Statement. Incidence rate was the number of injuries per 1000 player hours (i.e., the total duration from before the match starts to completion of the match after the final point). The magnitude of risk was expressed as a relative risk (RR) and its 95% confidence interval (CI). Independent risk factors were identified using multivariate analyses. A total of 161 tennis players were enrolled; 71 (44.1%) were men. Their mean age was 22 years old. The incidence rate of musculoskeletal injuries was 30.8 injuries per 1000 player hours (95% CI: 28.2–33.5). The most common onset was acute injuries (61.1%), while the most common location and type of injury was the trunk (38.9%) and muscle strain (61.1%). Risk factors associated with musculoskeletal injury were higher body height, skill level, history of previous injury, and wet bulb globe temperature (WBGT) zone. There was no injury during the doubles matches. Previous injury was an independent risk factor (adjusted RR: 48.1 (95% CI: 11.3–155.0; p < 0.001). The incidence of musculoskeletal injuries among professional tennis player is considerably high. Factors associated with injury are body height, skill level, previous injury, and WBGT zone. Future injury prevention programmes should incorporate the management of previous injuries and take into account the effect of environmental temperature.

The aim of this study is to determine the effect of reformer pilates trainings on ITN tennis test regarding the elite women aged 16-18 years. The research is done for voluntary participation of 14 elite female tennis players, whose age of training is 10,25 ± 1,72 years and average age 17,35 ± 0,77 years, All athletes were tested on the first day, then they were randomly divided into control (n=7) and experimental (n=7) groups. 90 minutes of pilates training sessions were performed for 3 days/week during eight weeks. The experimental group applied the pilates reformer studies and participated in the team trainings of the control group. After the 8-weeks training program, the last measurements of ITN Skills test were taken from experimental&control group athletes and the results were evaluated by SPSS 22.0 statistical program at 0.05 significance level. No significant difference was found for ITN depth&strength test, vole test, service test and stellar test when the last measurement test parameters of the experimental&control group athletes were compared (p>0.05). There was a significant difference between the two groups in the ITN sensitivity&strength test analysis (p<0.05). As a result, it can be said that 8-weeks duration pilates reformer trainings have an effect on the tennis players' ability to reach the ball on time in parallel and cross-strokes and an effect to have a recovery ability to be ready for the next shot.
