... Tennis, similarly to rhythmic gymnastics, is a sport with an asymmetric etiology, especially existing in the upper limbs. The asymmetric accumulation of fat mass and lean mass between the right and left arms give rise to disproportions in the bones (Vergauwen 1998;Sánchez-Muñoz et al. 2007;Rogowski 2008Rogowski , 2016Abrahão et al. 2008;Berdejo-del-Fresno 2010). On the other hand, swimming is a sport that involves all muscles and provides a balanced body composition. ...
Assessing bilateral differences in paired anthropometric features is an important methodological problem in sports anthropology. The present study included 128 adolescent female athletes (59 rhythmic gymnasts, 58 tennis players, and 11 swimmers). Body composition components were determined using multi-frequency bioelectrical impedance measurements (analyzer InBody 170). Asymmetry coefficients of muscle and fat mass accumulation in the upper (AA) and lower (AL) limbs were calculated using the Nacheva` equation (1986). The percentiles method was applied to distribute the bilaterally studied anthropometric features according to the mean values of the units of asymmetry (UA). Wilkoxon-test was used to assess the statistically significant differences in paired variables. Kruskal-Wallis test was applied to determine the differences in UA between three assessed athlete groups, depending on their age. The differences in body composition components between rhythmic gymnasts (RG), tennis players (TP), and swimmers (SW) were well expressed in all assessed age groups. The most considerable inter-group differences were observed in terms of the asymmetry coefficient in the lean body mass (LBM) with a right direction and body fat mass with a left direction for upper limb fat mass (%, kg), which have signed the highest values in the tennis players group, followed by the RG on the same age. Swimmers had significantly the lowest values of UA for all body segments. A close relation was found between asymmetry in body composition variables and the type of sports activity. Tennis was found as a sport with more pronounced inter-limbs asymmetry.
... Understanding the improvement of these physical attributes is crucial for coaches to enhance the overall tennis performance, aid in talent identification, and design tailored training programs. Several studies have used a longitudinal design in order to follow anthropometric and physical performance changes (3,22,27,28), and showed a significant improvement in both anthropometric and physical performance after the intervention period. ...
... While previous study have highlighted the importance of power, speed, and agility for tennis performance in heterogeneous groups of players (8), there is a need for longitudinal research to understand how these physical attributes develop and impact the performance level among junior tennis players. Otherwise, none of the latter studies (3,27,28) used a control group to compare the development of tennis players compared to sedentary participants. In our knowledge, the effects of practicing tennis on growing players have not been studied. ...

Background: Tennis, a sport demanding high levels of physical fitness, combines various aspects of athleticism such as agility, endurance, strength, and speed. The development of these attributes in junior players is crucial for their progress in the sport. Understanding the impact of structured tennis training on the physical fitness of junior players can provide valuable insights into the effectiveness of training programs and guide future coaching strategies.Objective:This study aimed to assess the effects of 1-year of tennis practice on the physical fitness of Tunisian junior players. Methods:Sixty-two healthy participants were enrolled, divided into two groups, tennis players (TP) (n = 36) and controls, where the participants sedentary, (n = 26), each group was divided into two subgroups U14 and U16 age-groups. Physical fitness tests were conducted at baseline (T0) and after one-year (T1), including standing long jump, countermovement jump, medicine ball throw (MBT), 5m, 10m, and 20m sprints, sideways shuffle, Zigzag, spider drill, 20m shuttle run, and sit and reach (SAR) tests. Results:Jump performances increased significantly for TP in U14 and U16 compared to controls at T0 and T1. In both age-groups, MBT performance increased significantly for TP, with U16 for both groups were higher at T0 and T1 (p<0.05). The 5m and 10m sprints increased significantly for TP in both age-groups, though controls decreased in the 5m sprint in U14 (p<0.05). The 20m sprint increased significantly for TP in U14 and U16 (p<0.05), with U16 outperforming U14 at T0 and T1 (p<0.05). Sideway shuffle and spider drill performances significantly improved for TP (p<0.05), while decreased in controls (p<0.05). The Zigzag test and the maximum oxygen intake increased significantly for TP across both age-groups at T0 and T1, whereas controls' performance decreasedin U14 (p<0.05). Conclusion:TP's SAR was significantly better than controls (p<0.05). In conclusion, tennis training enhances young athletes' physical fitness, improving agility, sprinting, jumping, and endurance compared to controls, reporting better results in U16 compared to U14 for most of tests.

Background: The popularity of Tunisian tennis is on the rise, due to emerging players gaining global recognition, leading to growth and evolution in the sport. In order to optimize training and performance, coaches need valuable information on physical fitness and player profiling. Objectives: The study aimed to investigate the physical profile of Tunisian tennis players in different age groups ranging from 7 to 17 years. Methods: Ten players from the same team were assigned to six age groups (U9-U18); U9 (7.89 ± 0.32), U10 (8.88 ± 0.34), U11 (9.78 ± 0.43), U12 (10.81 ± 0.4), U14 (12.3 ± 0.73), and U18 (14.69 ± 0.95) and were assessed for standing long jump (SLJ), countermovement jump, medicine ball throw (MBT), various sprint distances, agility drills, 20m Shuttle run (20mSRT), and Sit and reach tests. Results: The results showed that U14 and U18 age groups demonstrated better performance than U9 and U10 in jump tests, while U18 and U14 outperformed only U9 in the MBT test. U11 showed better performance than U9 and U10 in sprints, sideways shuffle, and spider drill tests. U9 and U10 had lower performance than U12 in SLJ, 20m sprint, sideways shuffle, and zigzag tests, and U11 outperformed U9 in the SLJ test. U18 and U14 had higher VO2max than U10 and U11, while U12 was higher than U11 only. No difference in flexibility was reported. The centile estimates of physical performances among Tunisian tennis players provide a means to compare individual player test results with the standard performance levels of the group. Conclusions: In conclusion, this study found that 11–17-year-old players exhibited greater physical performance than 7–10-year-old players. However, no age effect was found for flexibility.

Introduction : The intensity of tennis training together with specific exercises may be reflected in the morphological profile of tennis players.
Aim : To evaluate the impact of sports training on the body composition of female tennis players in the 11–13-year competition category.
Materials and methods : The study included an experimental group of 27 female tennis players (mean age 12.43±0.91 years) and 115 schoolgirls (mean age 12.55±0.88 years) as a control group. The following features were investigated: body height, body weight, body mass index, waist-to-hip ratio, muscle mass, fat mass, fat-free mass, percentage of body fat, total body water. The visceral adipose tissue and subcutaneous adipose tissue were computed using the Brambilla’s equation.
Results : In comparison with the control group, tennis players have higher values of muscle mass ( p <0.04), total body water ( p <0.05), fat-free mass ( p <0.04) and lower values of body fat percentage ( p <0.04). The rest of the parameters were not found to have statistically significant differences.
Conclusions : We conclude that sports training influences some morphological parameters of female tennis players.
... En cuanto al rendimiento físico en tenistas adolescentes, varios autores han planteado que su evaluación debe incluir el monitoreo de su maduración biológica Ulbricht et al., 2015;Lloyd et al., 2014). En esta misma línea, la mayoría de información disponible que ha estudiado el rendimiento físico en jóvenes tenistas, incorporando distintos indicadores corporales y de aptitud física, es de origen europeo (Berdejo-del-Fresno et al., 2010;Munivrana et al., 2015;Myburgh et al., 2016;Fett et al., 2017;Kramer et al., 2017;Kramer, Huijgen et al., 2016;Kramer, Valente-Dos-Santos et al., 2016;Férnandez-Férnandez et al., 2019;Ulbricht et al., 2015Ulbricht et al., , 2016. Por su parte, en Sudamérica, las indagaciones parecen ser aún incipientes y se han enfocado, principalmente, al estudio de aspectos antropométricos (Rica et al., 2019;Schluga Filho et al., 2016), de la carga externa del juego (Rodríguez y Montoya, 2018) y de la inserción de este deporte con enfoque un socio-cultural (Silva et al., 2017). ...
El estudio tuvo como objetivo analizar los artículos científicos originales, disponibles en bases de datos en los últimos veintiún años (2000-2021), acerca del monitoreo de la antropometría y aptitud física en jóvenes tenistas. Se realizó una revisión sistemática en tres bases de datos electrónicas: PubMed, LILACS y Web of Science, entre enero del 2000 a mayo del 2021; se identificaron inicialmente 73 artículos originales que, posterior a la aplicación de los criterios de elegibilidad y exclusión, junto con el procedimiento presentado en el flujograma PRISMA, permitieron obtener 14 artículos, que fueron analizados cualitativamente. Los resultados evidencian que existe la necesidad de mayores indagaciones, especialmente a nivel sudamericano y en las mujeres; no obstante, es importante señalar que estos estudios aportan con referencias antropométricas muy similares a las encontradas en otras regiones del mundo. Por otro lado, la antropometría y el desempeño en pruebas de aptitud física presentan mejores indicadores en relación con la edad cronológica, rendimiento en la modalidad (ranking nacional) y entrenamiento específico. Al comparar por género, existen diferencias significativas en antropometría y pruebas de aptitud física. Finalmente, tanto en mujeres como en hombres, la maduración avanzada se asocia al mejor desempeño en las pruebas de velocidad de desplazamiento, de fuerza y potencia muscular. Es necesario considerar esta información para mejorar el rendimiento deportivo, detección de talento y prevenir lesiones en tenistas adolescentes.

Abstract
The aim of the study was to determine some morphological differences between sides of body (dominant
versus non-dominant) of elite junior badminton players. The sample consisted of 85 high profile junior
badminton players from Europe that have played on European Junior Circuit. They were gauged with 12
morphological measures aiming to gain some basic information regarding the players’ morphological status
and to establish relations between dominant and non-dominant side of the body, by comparing
circumferences of limbs on both sides. The results obtained by the study have established significant
(forearm and upper leg; p= 0,00) or non-significant (p=0,11), but nevertheless visible (30,49±16,96
opposed to 27,51±2,42) differences (upper arm) between circumferences of limbs of badminton players on
opposite sides of their bodies, with higher values shown on the dominant side. The only exception of the rule
has been shown on the lower leg circumference (36,58±2,58 opposed to 38,09±12,57). Badminton players,
due to unilaterality of the sport, are predisposed to develop some morphological imbalances, which can both;
increase potential risk of injuries and negatively influence players’ performances in the game. Therefore,
additional bilateral physical exercises that would help diminish some negative consequences of frequent and
intensive badminton training and would enable symmetrical development of young badminton players’,
should be implemented in their training.
Key words: anthropometry, unilaterality, dominant side, asymmetry
... Trainers working with children prefer anthropometric, physical, and physiological fitness tests and norms for talent selection, and performance evaluation. There haven't been much research on determining anthropometric, body composition, and physical fitness levels among children, and as far as it is know, no researchhas been conducted on the relationship between ITN test and anthropometric, physical and physiological fitness parameters (Girard et al. 2009;Berdejo-del-Fresno et al. 2010;Pion et al. 2014;Olcucu 2013;Olcucu 2015). Optimal training programs can be created, by determining physical fitness values for this age group. ...
... They have analyzed the skeletal muscle-bone structure and function, (Gallotta et al. 2014;Lädermann et al. 2014;Bodor and Jarosz 2015) cardiac structure and function (Baiget et al. 2014), injury (Maquirriain and Baglione 2015;Dines et al. 2015), aerobic fitness and physiolog- ical response to competition (Murphy et al. 2014;Gallo-Salazar et al. 2014;Brink-Elfegoun et al. 2014;Fernandez-Fernandez et al. 2015). However, when focussing on children tennis players, relatively few studies have investigated the antropometric, body composition and physical fitness levels (Girard et al. 2009;Berdejo-del-Fresno et al. 2010;Pion et al. 2014;Olcucu 2013;Olcucu 2015). ...
The purpose of the present research was to determine the anthropometric, body composition, physical, fitness parameters and ITN scores and levels among children tennis players and to define the relationships between these anthropometric, body composition, physical fitness parameters and ITN scores and levels. 30 female children tennis players between eight to tenyears of age, who have the Turkish Tennis Federation club licence and individual licences were included in the study. The subjects were tested on four different performance variables, namely, the anthropometric, body composition, physical fitness and ITN levels profiles. For data analysis, the Pearson coefficient was calculated. According_ to the research findings, there are no significant relationships between ITN total scores and any of the anthropometric and body composition values. On the other hand, there are significant positive relationships between ITN total scores and ball throwing, vertical jumps, standing broad jumps, and reverse sif-ups. There is a negative significant relation between ITN total scores and auditory reactions. Similarly, there are no significant relationships between ITN values and any of the anthropometric and body composition values. There are negative significant relationships between ITN values and ball throwing, vertical jumps, standing broad jumps, and reverse sit-ups. There is a positive significant relation between ITN values and auditory reactions. In conclusion, this study indicated that ball throwing, vertical jumps, standing broad jumps and back extension variables were statistically linked to specific performance levels identified via the ITN levels.
