Deshpande, Y., Jackson, R., King, M., Cockram, A., Goosey-Tolfrey, V. “… With no existing research exploring the time constraints in wheelchair tennis (WT), the role of anticipation in effectively returning WT serves is unknown. Therefore, the aims of this study were (1) to quantify the time constraints in the serve return dyad in WT, (2) to understand the relationship between serve quality, receiver response, and return shot outcomes, and (3) discuss the importance of anticipation skill in WT serve returns.  …”

Koopmann, T., Faber, I., Lath, F., Loffing, F., Schorer, J. “… ., 2021) and their specific criteria used are widely unknown. To address this gap, we conducted in-depth semi-structured interviews with fifteen coaches (five female, ten male; age: 32-78 years, M = 55, SD = 12.96) with high expertise in the identification and development of young talented table tennis players (10-60 years of experience, M = 28.80, SD = 13.94 years).  …”

Kuo, C. Y., Lin, Y., Lin, T. C., Guo, C. W., Chu, H. H., Huang, C. C., Lin, J. F., Lai, H. Y., Chen, Y. H. “… Moreover, whether rotation of the serve has an impact on this strategy (fixing the first bounce) remained unknown. Therefore, the aim of this study was to investigate the bounce location of short and deep serves with different rotation types, with and without using this strategy.  …”

Martin, C., Touzard, P., Lecomte, C., Fadier, M., Fourel, L., Cantin, N., Bideau, B., Kulpa, R. “… However, the short-term effects of the racket scaling constraint on serving performance, kinematics and joint loadings are unknown. As a consequence, this study aimed to assess the effect of racket size on the serve biomechanics and performance parameters for young tennis players METHODS: 9 young intermediate competitive tennis players (age: 9.9 ± 1.0 years) performed maximal effort successful flat serves with 3 different rackets (scaled 23 inches, scaled 25 inches and full-size 27 inches) in a randomized order.  …”

Koopmann, T., Faber, I. R., Lath, F., Loffing, F., Schorer, J. “… However, the selection criteria used by coaches and the decision-making processes in player selection contexts are widely unknown. To address this gap, we conducted 15 in-depth semi-structured interviews with table tennis coaches with high expertise in the identification and development of talented young players.  …”

Jiménez, L. “… Although it is becoming more and more commonplace, the consequences of common mental health problems such as anxiety, depression and sleep disorders are still unknown. For this reason, this article presents a series of strategies that could be carried out by federations, advocating the implementation of programmes focused on the prevention and promotion of mental health and well-being.  …”

Kolman, N. S., Huijgen, B. C. H., Visscher, C., Elferink-Gemser, M. T. “… Introduction: Technical skills in complex situations appear crucial for progress towards elite tennis performance. However, it is unknown how these skills develop in different age categories in a group of talented youth players.  …”

Lambrich, J., Muehlbauer, T. “… However, the influence of stroke direction on plantar pressure in tennis players with diverging skill level is unknown. Thus, the purpose of this study was to determine the effect of stroke direction on plantar pressure in each foot during the forehand and backhand stroke among players of different performance levels.  …”

Kolman, N. “… However, the relationship between technical skills in a tennis-specific situation and perceived tactical skills has not been investigated yet, and also the association with self-regulatory skills is unknown. Therefore, the purpose of this study is to explore the relationship between technical skills in various tactical situations, perceived tactical skills and self-regulatory skills among 21 youth elite tennis players (13 males, 8 females; age range 12-18 years).  …”

Goh, W. X., Lee, M. J. C. “… The trade-off between more intense rallies and more rest time on energy expenditure remains unknown and would be an interesting area to investigate for targeted prescriptions of training programmes. …”

Chang, B.-F. “… The impact of that asymmetry on future injuries remains unknown. …”

Yin, D., Wang, X., Zhang, X., Yu, Q., Wei, Y., Cai, Q., Fan, M., Li, L. “… However, it is largely unknown what plastic changes in specialization and flexibility in visual-motor areas occur in support of extraordinary motor skills in expert athletes and how the selective adaptability of the visual-motor system affects general perceptual or cognitive domains.  …”

Faber, I., Oosterveld, F., Nijhuis-Van der Sanden, R. “… Because the key-factors which determine talent for table tennis are unknown, research to get a scientific fundament for a talent identification system for table tennis sports is desirable.  …”

Vereijken, A., Aerts, I., Jetten, J., Tassignon, B., Verschueren, J., Meeusen, R., van Trijffel, E. “… Even though functional performance tests are often used to make return to sport decisions, it is unknown whether functional performance is associated with return to performance after such injuries.  …”

Sindik, J., Sarac, J., Missoni, S., Schuster, S., Grgurinovic, T., Tomic, D., Kondric, M. “… Routine medical examinations are particularly important to determine current health status of the athletes, to provide information about risk factors and still unknown critical congenital dysfunctions at individual players.  …”

Fitzpatrick, A., Stone, J. A., Choppin, S., Kelley, J. “… However, the performance characteristics (e.g. aces, first serve points won, forced errors) most associated with success on different surfaces are currently unknown. With three weeks typically separating Roland Garros and Wimbledon, the transition from clay to grass courts, whereby players must adapt their game style between surfaces, is crucial to understand.  …”

Cren Chiminazzo, J. G., Barreira, J., Cabello-Manrique, D. “… Winner players perform significantly more WP, while loser players perform more UE. However, it is unknown how the interaction between UE and WP may influence the match outcome.  …”

McLachlan, J., Lonas, T., Dancs, J., Knobloch, D., Darrow, C., Sinn, E., Davis, S., Neilly, D., Funk, A., Golz, J., Phelps, A., Goer, B., Post, S. “… Unknown …”

Caudrelier, T. R. “… Elite racket sports players have been shown to be able to anticipate strokes in advance of kinematic stroke information, although the use of this ability in match situations is relatively unknown. Previous studies have not considered shot difficulty or the extent to which situational probabilities can influence anticipatory behaviour.  …”
