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.

... Badminton players due to unilaterality of the sport and its specific playing technique very often show an increased level of strength of the dominant hand (Fresno et al., 2010). Moreover, several studies have found asymmetry of the upper limbs (Andreoli et al., 2001; Ilnicka, 2005; SanchisMoysi et al., 2004; Colak et al., 2004; Lucky et al., 2007; Rogowski et al., 2008; Balius et al., 2012; Bass et al., 2002; Ducher et al., 2009; Ducher et al., 2006; Sanchis-Moysi et al., 2010; SanchisMoysi et al., 2010; Moreno et al., 2002). ...
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.
... However, 5 were evaluated 29 tennis players with average age of 14 years old and the average measurement showed a body mass of 53.5 kg and height of 162 cm, similar numbers to this research. In congruence, 18 when observing Spanish young tennis players, reported a body mass of 40.36 ± 5.57 kg and height of 147.7 ± 0.1 cm, which corroborate this current study. It is realized that the body mass in puberty is allometric, what means that it increases proportionally to the height. ...

Objective: Determine the motor and morphological characteristics of amateur tennis players from 11 to 15 years old.
Method: 11 male athletes from the Paranaense Tennis Federation were evaluated during the competition period. Anthropometric variables (total body mass, height, circumference and skinfolds) were assessed.
Results: The following median values were obtained: 45.8 kg of total body mass, 160 cm of height, fat percentage of 14%, lean mass of 37 kg, and fat mass of 5 kg.
Conclusion: The study concluded that athletes show a profile of body composition similar to the profile of tennis players of the same age.
... The result obtained (10.18 s) in this study was similar to the value obtained by Berdejo-del-Fresno [48] in relation to Spanish male junior basketball players at the beginning of the season (10.13 s) and better than that found in highly trained Spanish young tennis players at specific times during the season (11.42-11.37-11.05 s) [53,54]. The Agility 2 test did not show any differences between the legs with respect to the changes in direction; it is therefore deduced that in the subjects there is not any unbalance between the lower limbs in terms of agility. ...
Background: Basketball is one of the most practised sports in the world. There is a huge amount of articles analyzing the anthropometry of basketball players, the parameters of basketball, its physiological demands, and the fitness level of the teams. However, the vast majority of these studies focus on male basketball players. There are only a few studies working on British high-level female basketball teams. Research question: To evaluate and compare the body composition and fitness characteristics of elite British female basketball players in relation to other studies. Type of study: Descriptive study. Methods: 14 elite level female basketball players from a top-4 team that compete in the England Basketball League Division I voluntarily participated in this study. The anthropometry measurements performed were: weight, height, arm span, BMI, and skin folds. The fitness tests were: Flexibility (sit and reach), Agility 1 (4x10-meter shuttle run), Lower Body Power 1 (Standing Broad Jump), 20-meter shuttle run, Sprint (5 and 10-meter), Agility 2 (Left and Right), Lower Body Power 2 (Hop, Triple Hop, Cross-over Hop), and Yo-Yo Test. Results: Statistical differences were found between the right and left leg of players in the Triple hop (p=0.04) and Cross-over hop (p=0.01). Furthermore, regarding VO2max, statistical differences were found between the VO2max that had been calculated by Yo-Yo IR2 and the VO2max that had been calculated by the 20-meter shuttle run test, without taking into account the players' age (p=0.002). Conclusions: The sample analyzed of elite British female basketball players had fitness level and body composition values lower than high-level female basketball teams from countries where basketball is more popular and better developed.
The aim of the present study is to investigate a grip strength in young male tennis players aged 9-11 years. A total of 39 children (15 tennis players and 24 pupils) took part in the study. All participants were assessed for height, weight and BMI. The grip strength was measured by hand dynamometer in kilograms-force at both (dominant and non-dominant) upper limbs. Statistical analysis was made by SPSS 16.00 for Windows. The measuring showed that sportsmen have higher values on right upper limb hand grip strength than the control group (11.8 kg and 8.00 kg). There are similar results on the left upper limb: 7.79 kg (athletes) and 6.92 kg (non-athletes). A considerably higher difference of hand grip strength between the right and left hand was discovered in athletes (3.67kg.), compared to the control group (0.87 kg). The correlation is significantly higher between the left hand grip strength and body mass index (p < 0.01), weight and hand grip strength on the left hand (p < 0.05), and height and right hand grip strength (p <0.05) in athlete group. Only in non-athlete group there is a high level of correlation between right and left hand grip strength (p < 0.01).
Aim: The aim of this study is to determine some physiological and biomotor properties of 9-13 years old tennis players, and detect the effect of gender on performance.
Material and Methods: 19 voluntary male tennis players, (average age: 11.21±1.08 year, average height: 1.52±0.11 cm, average weight: 44.76±7.87 kg, average sport background: 3.15±1.11 year ),17 voluntary female tennis players, (average age: 11.05±1.51 year, average height: 1.48±0.08 cm, average weight: 35.84±5.75 kg, sport background: 2.7±0.91 year ) who exercise at a tennis club in Ankara participated in this study. The subjects’ anthropometric measurements were taken. Then, 5 m sprint test, 10 m sprint test, flexibility test, push up test, sit up test, long jump test, medicine ball throw test, stability test were performed on the mentioned subjects. After calculating the descriptive statistics of the voluntaries, the data collected from performance tests were evaluated with Levene test and it showed normal distribution. T test was used to identify which groups had significant differences.
Results: In the applied test, it has been observed that except the 10-m sprint test; there were not any significant (p
