Objective: Investigate the relationship between the initiation age and practice time, in training and competition, and the ranking position of youth elite tennis players.  Method: Participated 130 youth elite tennis players with a Brazilian ranking (102 boys and 28 girls) aged 13–18 years, selected in two international competitions. A Binary logistic regression was performed. Results: The results showed that tennis players who started earlier have a 28% better chance of reaching the top 20 ranking, and that each additional year of training increases the chance of a tennis player to reach the top 20 by 1.43 times. Also, each year of experience in competitions increases the chance of tennis players to reach the top 20 ranking by 1.41 times, and that an earlier start each year in participating in competitions increases the chances of an athlete to reach the top 20 by 20%. Conclusion: The initiation age of training and the experience in competitions are important factors there are related to better ranking positions of youth elite tennis players.

The aim of this study was to identify the physical factors related to serve speed in male professional wheelchair tennis players (WT). Nine best nationally-ranked Spanish male wheelchair tennis players (38.35 ± 11.28 years, 63.77 ± 7.01 kg) completed a neuromuscular test battery consisting of: isometric handgrip strength; serve velocity; 5, 10 and 20 m sprint (with and without racket); agility (with and without racket); medicine ball throw (serve, forehand and backhand movements); and an incremental endurance test specific to WT. Significantly higher correlations were observed in serve (r = 0.921), forehand (r = 0.810) and backhand (r = 0.791) medicine ball throws showing a positive correlation with serve velocity. A regression analysis identified a single model with the medicine ball throw serve as the main predictor of serve velocity (r2 = 0.847, p < 0.001). In conclusion, it is recommended that coaches and physical trainers include medicine ball throw workouts in the training programs of WT tennis players due to the transfer benefits to the serve speed.

Tennis Match

The aim of this study was to examine the impact of a tennis player’s body language and clothing (general vs. sport-specific) on the impressions observers form of them. Forty male tennis players viewed videos of a target tennis player warming up. Each participant viewed the target player displaying one of four combinations of body language and clothing (positive body language/tennis-specific clothing; positive body language/general sportswear; negative body language/tennis-specific clothing; negative body language/general sportswear). After viewing the target player, participants rated their impressions of the model’s episodic states and dispositions and gave their perceptions of the likely outcome of a tennis match with the target player. Analyses of variance revealed that positive body language led to favorable episodic impressions and low outcome expectations. Analysis also indicated that clothing and body language had an interactive effect on dispositional judgments. The study supports the contention that nonverbal communication can influence sporting interactions.

Despite a growing body of research into sports coaching there remains little understanding of what it is like to coach elite junior tennis players. The purpose of this study was to examine the lived coaching experience of 8 UK, less experienced tennis coaches and describe what it is like to be a coach of an elite junior tennis player.  An Interpretative Phenomenological Analysis (IPA) of 8 less experienced tennis coaches (1 – 4 years-experience) provides a description of how they described elite junior tennis coaching.  This study found that (a) self-employment makes coaching competitive, (b) less experienced coaches were surprised by the nature of parental interactions, and (c) less experienced coaches struggled to cope with the reality of coaching and this triggered disillusionment with coaching.   The findings of this research contribute to an evolving, problematic epistemology of sports coaching and highlight a need for tennis coach education to improve the preparation of new coaches for their initiation into coaching.   The findings present governing bodies opportunities to inform coach education literature and help tennis coaches to sustain themselves in an emotionally challenging role.

Abstract This study investigated tennis players’ speed before, during and after the split-step, deceleration before and acceleration after the split-step in four different stroke groups in three age categories. Seven male professional, eleven male and ten female junior tennis players were recorded with video cameras at official tournaments. Using the SAGIT system, we gathered data on 8,545 split-steps. Tennis players performed a split-step in 82.9% of cases. A tennis player’s speed, deceleration and acceleration were measured 0.2 s before and after the split-step. Differences between categories and stroke groups for each of the five variables were analyzed with a two-way ANOVA. The differences between the groups of players were generally much higher in the speed before, during and after the split-step than in the deceleration before and acceleration after the split-step. Most of these differences were observed between the various stroke groups. These results suggest that players use three types of movement while performing a split-step. In the first type, which is typical of serving and returning, the speed before, during and after the split-step is lower (0.55 to 1.2 m/s). The second type of movement is characteristic of baseline strokes where tennis players achieve higher speed than in the first type (0.7 to 1.66 m/s). The third type occurs in strokes where a tennis player is moving or already at the net (0.78 to 1.9 m/s). Movement in tennis is an area that requires constant development in terms of designing and upgrading movement patterns, increasing speed and practice in specific game situations.

High speed torque is very important in tennis batting process , this paper discusses the shoulder and torso rotation torque generated by the weight of tennis sports influence. Taking 48 tennis players as research objects, the rotation torque of professional tennis players are relatively outstanding with performance value,so we concluded that in the case of keeping the torso erect and through the process optimization of the rotation, we could combined shoulder movement and body bottom-up movement. These results suggested that some given hitting model can not only increase the performance of the tennis player on the pitch, but also reduce the risk of causing excessive damage.

This study analyzed the process of socialization of elite tennis players, thereby contributing to an explanation of the success experienced by Swedish tennis players in recent years. The top five male and top five female Swedish players, along with parents and coaches, were interviewed regarding background, early life sport experiences, and development. All five males held ranking positions among the 15 best in the world. The control group was chosen by matching pairs regarding age, sex, and junior ranking. Results indicated that both groups at the ages of 12 to 14 were equal, but after puberty the development of the groups diverged. As teenagers, some elite players were ranked among the world’s top players while the control group players did not experience success. The results clearly indicate that it is not possible to predict who will develop into a world-class tennis player based on individual talent alone. Personal qualifications and early life experiences in combination with social structures, tradition of sport, and tennis culture all worked together in an optimal way, particularly the local club environment and the players’ relationships to coaches.
