IMPACTO DAS LESÕES MUSCULOESQUELÉTICAS EM ATLETAS AMADORES DE BEACH TENNIS

Musculoskeletal injuries have been constantly related to sports, being considered a common problem among athletes and that directly affects their sports performance. In view of the above, for the purposes of this study, we sought to evaluate the impact of musculoskeletal injuries in amateur beach tennis athletes in the city of Gurupi-TO. To carry out this study, it was a field research, with amateur beach tennis athletes. A questionnaire on sports context and musculoskeletal injuries was applied, totaling 22 closed and open questions. The inclusion criteria adopted were: beach tennis players aged 18 years or older, male and female, resident in the city of Gurupi-TO. In total, there were 72 respondents. In the results, among the main information found, the knee and shoulder regions were the most cited regarding the site of injuries during the practice of beach tennis; Physical Therapy and Orthopedics professionals were the most requested to deal with injuries; pre- and post-workout stretching and pre-workout warm-up activities were the most cited as those that help prevent injuries during sports activities; physical preparation and the necessary recommendations are the two most efficient methods for preventing and treating sports-related musculoskeletal injuries. With this, it was possible to observe that the practice of beach tennis did not in fact cause sports-related musculoskeletal injuries to the participants of this research.

Benefits of Table Tennis for Children and Adolescents: A Narrative Review.

This study aims to review the scientific evidence regarding the effects of table tennis practice on children and adolescents. Studies were searched in three electronic databases (PubMed, Scopus, and SportDiscus) from their inception up to May 2024. The methodological quality of the included studies was assessed using the 10-point Physiotherapy Evidence Database (PEDro) and Methodological Index for Non-Randomized Studies (MINORS). A total of twelve studies were examined, with interventions involving children with intellectual disabilities, ADHD, DCD, ASD, and typically developing children. A variety of training programs were assessed over durations ranging from 6 weeks to 1 year in the studies included. Table tennis was shown to positively impact various domains, including executive function, motor skills, visual perception, graphomotor function, gross motor skills, coordination capacity, behavioral inhibition, and social behavior. Nonetheless, it is imperative to expand the number of studies on children and adolescents with diverse conditions to more comprehensively evaluate the benefits of table tennis for each specific condition.

Altered spontaneous regional brain activity in ventromedial prefrontal cortex and visual area of expert table tennis athletes.

Sports training may lead to functional changes in the brain, and different types of sports, including table tennis, have different influences on these changes. However, the effects of long-term table tennis practice on brain function in expert athletes are largely undefined. Here, we investigated spontaneous regional brain activity characteristics of expert table tennis athletes by using resting-state functional magnetic resonance imaging to compare differences between 25 athletes and 33 age- and sex-matched non-athletes. We analyzed four metrics-amplitude of low-frequency fluctuation (ALFF), fractional ALFF, regional homogeneity, and degree centrality-because together they identify functional changes in the brain with greater sensitivity than a single indicator and may more comprehensively describe regional functional changes. Additional statistical analysis was conducted to assess whether any correlation existed between brain activity and years of table tennis training for athletes. Results show that compared with non-athletes, table tennis athletes showed altered spontaneous regional brain activity in the ventromedial prefrontal cortex and the calcarine sulcus, a visual area. Furthermore, the functional changes in the calcarine sulcus showed a significant correlation with the number of years of expert sports training. Despite the relatively small sample size, these results indicated that the regional brain function of table tennis athletes was associated with sports training-related changes, providing insights for understanding the neural mechanisms underlying the expert performance of athletes.

INJURY EPIDEMIOLOGY IN BEACH TENNIS: INCIDENCE AND RISK FACTORS.

Due to the growing increase in beach tennis practice in Brazil and the lack of studies on the injuries that occur in this sport, it has become necessary to develop more research on the subject. to identify risk and protection factors for injuries in beach tennis, in order to generate prevention strategies for musculoskeletal injuries. A cross-sectional epidemiological study, level 3 of evidence, was carried out through an electronic form with 698 Beach Tennis players, who answered questions about their relationship with the practice of the sport and occurrences of injuries. We researched the prevalence of injuries, their types, and their relation with personal physical characteristics and the practice of other sports. We found a positive relationship between injuries when associated with longer exposure time and the presence of a previous injury. We did not find differences regarding BMI, gender, and stretching and muscle strengthening performance. the most frequent non-traumatic injuries were to the elbow and shoulder (tendonitis) and traumatic (sprain) injuries to the knee and ankle.

Effects of an 8-week multimodal program on thoracic posture, glenohumeral range of motion and serve performance in competitive young tennis players.

Intensive tennis practice is known to generate sport-specific adaptations at the shoulder region and influence the sagittal spinal curvature. However, increased thoracic kyphosis decreases the shoulder functional capacity, which could limit tennis performance. Therefore, the aim of this study was to investigate the effects of an 8-week multimodal program on thoracic posture, glenohumeral range of motion, and serve performance in competitive young tennis players. Eighteen male and four female players (age: 16.0 ± 2.4 years, height: 170.7 ± 11.0 cm; mass: 62.1 ± 11.5 kg; International Tennis Number: 3-4) performed their regular training during 8 weeks, which was used as a reference period, and implemented a multimodal program including stretching, strengthening, and myofascial release exercises, four times per week during 8 additional weeks, which corresponded to the intervention period. The thoracic curvature angle and mobility, the biacromial and interscapular distances, the glenohumeral range of motion and the tennis serve performance were assessed three times, i.e., before and after the regular training and after the 8-week multimodal program. The results showed that the 8-week regular training had no significant effects on thoracic curvature angle [effect size (ES) = 0.02-0.36, p = 0.06-0.46] and mobility (ES = 0.05-0.26, p = 0.13-0.42), biacromial (ES = 0.05, p = 0.18) and interscapular distances (ES = 0.03, p = 0.45), ranges of motion in glenohumeral internal (ES = 0.04, p = 0.43) and external rotation (ES = 0.43, p = 0.06), and tennis serve accuracy (ES = 0.33, p = 0.07) and velocity (ES = 0.09, p = 0.35). The 8-week multimodal program increased moderately the thoracic mobility (ES = 0.55, p = 0.01), moderately to strongly the serve accuracy and velocity (ES = 0.65, p = 0.003, for both), strongly decreased the interscapular distance (ES = 1.02, p < 0.001), and strongly increased the range of motion in glenohumeral internal (ES = 0.90, p < 0.001) and external rotation (ES = 1.49, p < 0.001). These findings indicated that an 8-week multimodal program, including spine and glenohumeral mobility and shoulder girdle strength exercises, performed four times per week during 8 weeks, is moderately relevant to rectify the sagittal thoracic curvature in competitive tennis players, while such a program may help regain the range of motion in glenohumeral rotation without tennis serve performance impairment.

Tennis representations in the 20th-century Brazilian press: women’s bodies in focus

ABSTRACT Involved in representations that produce meanings according to the characteristics of each time and space, the human body is a record of history and culture. The media is one of the instruments that convey these meanings, and, as tennis was a sport considered beautiful and without physical contact, it represented a practice that did not disfigure the femininity of cisgender women. Therefore, this study sought to discuss how the sport of tennis was represented in a women’s magazine in the mid-20th century in Brazil, analyzing the stereotypes behind such a representation. For this, we used the pages of the Brazilian magazine Jornal das Moças and defined the period in which it was distributed as being from 1914 to 1965. We identified different representations of the tennis practice that reinforced whiteness and specific stereotypes, such as cisness and heteronormativity, when encouraging women to be attractive to men, with tennis supporting the importance of women in the constitution of families and being an opportunity for women from ruling classes to leave the domestic environment. In addition, it involved aspects of health maintenance and forms of beautification capable of developing physical characteristics that received high praise in virtue of the type of femininity.

CONSEQUÊNCIAS DO TREINAMENTO COMPOSTO SOBRE A MOBILIDADE DOS JOGADORES DE TÊNIS

ABSTRACT Introduction: Considering the sports practice of tennis, several researchers are looking for the reasons that can benefit the movement technique of its players. It is currently believed that the use of compound training can provide beneficial results to tennis players. Although there is some empirical evidence, this theory lacks scientific references for developing based mobility training for its practitioners. Objective: Study the consequences of combined training on the mobility of tennis players. Methods: The experimental and statistical-mathematical method was adopted in 36 young tennis players. Divided equally between the experimental and control group, the former received 6 weeks of training by a compound experimental protocol. A comparative study was conducted on deceleration ability, mobility, and other indicators with the control group, which received conventional training in the same period. Results: In the standard 10m short-run deceleration test, the experimental and control groups showed no significant differences (P=0.66, 0.59&gt;0.05). In terms of the completion time of the acceleration of the 30m run and the completion time of the fan-shaped run, simulating the movement characteristics of tennis shoes, there was a significant difference (P=0.11&gt;0.05, P=0.82&gt;0.05). Conclusion: Adding compound training into traditional tennis training can positively affect compound deceleration ability and movement ability among young tennis players.

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.

Vitreo‐retinal injuries in the practice of padel, a problem on the rise

AbstractPurpose: Paddle tennis is considered a sport with high ocular risk. The most frequent eye injuries are caused by the impact of shovels, balls or earth particles, with injuries to the posterior pole of the eye (retina and vitreous) being the most serious and can lead to loss of vision due to retinal detachment, choroidal tears or eye burst many times due to not using adequate protection. In this paper, we analyse posterior pole injuries and their treatment.Methods: The cases of ocular injuries in the practice of paddle tennis in the last three years seen in the ophthalmology emergency service of our hospital have been collected.Results: 34 patients have been included, 30 men and 4 women, with a mean age of 34 years. The initial visual acuity was 0.74 and the final visual acuity was 0.9. The lesions seen have been retinal edema, vitreous haemorrhages, retinal haemorrhages, retinochoroidal tears, retinal tears, macular hole, vitreous base avulsion and angular recession glaucoma, in many cases associating more than one type of injury. In most cases, topical treatment (25 cases), topical and oral (5 cases), laser (5 cases) and surgery (3 cases) have been performed. In no case, did they use eye protection.Conclusions: Most of the cases presented good initial visual acuity, however, all presented potentially serious lesions in the posterior pole (retina and/or choroid), including two cases of retinal detachment and one angular recession glaucoma that required surgery. For this reason, it is necessary to insist on the use of approved polycarbonate protective glasses for all players and in case of ocular contusion, review by the ophthalmology service to assess the eye fundus regardless of the initial vision.

Effects of table tennis practice on balance and physical fitness in the elderly

The Table Tennis game does not involve large displacements by the practitioner in the environment, a characteristic that can promote greater safety for the elderly in locomotor terms. In addition, it needs coordination, agility, speed of reaction, dynamic balance, which have been the focus of current recommendations of physical activity for the health of adults and the elderly. The aim of this study is to investigate the effects of table tennis practice on physical and functional fitness in the elderly. This quasi-experimental research with a parallel and controlled design. The sample consisted of 16 elderly people, allocated 8 in the experimental group (EG) and 8 in the control group (CG). The research lasted 18 weeks, with 2 weeks of evaluation (initial and final) and 16 weeks of intervention. Physical fitness assessments were carried out using the agility and balance and functional fitness tests. In the intra-group comparison (pre-post intervention), EG showed a significant difference for the variable agility (pre: 15.6 ± 1.2 s; post: 14.7 ± 0.7 s). Also, the EG showed a reduction in Area (pre: 11.00±3.32 cm2; post: 6.52±3.06 cm2), AP Amplitude (pre: 4.92±2.77 cm; post: 3.28±0.58 cm) and ML speed (pre: 2.77±1.07 cm/s; post: 2.31±1.03 cm/s) in the Tandem posture with eyes open. Our findings highlight the importance of a Table Tennis program, administered twice a week and consisted of low to moderate intensity activities, to promote a beneficial effect on the agility and balance of physically active elderly people.

Real-Life Application of a Wearable Device towards Injury Prevention in Tennis: A Single-Case Study.

The purpose of this article is to present the use of a previously validated wearable sensor device, Armbeep, in a real-life application, to enhance a tennis player’s training by monitoring and analysis of the time, physiological, movement, and tennis-specific workload and recovery indicators, based on fused sensor data acquired by the wearable sensor—a miniature wearable sensor device, designed to be worn on a wrist, that can detect and record movement and biometric information, where the basic signal processing is performed directly on the device, while the more complex signal analysis is performed in the cloud. The inertial measurements and pulse-rate detection of the wearable device were validated previously, showing acceptability for monitoring workload and recovery during tennis practice and matches. This study is one of the first attempts to monitor the daily workload and recovery of tennis players under real conditions. Based on these data, we can instruct the coach and the player to adjust the daily workload. This optimizes the level of an athlete’s training load, increases the effectiveness of training, enables an individual approach, and reduces the possibility of overuse or injuries. This study is a practical example of the use of modern technology in the return of injured athletes to normal training and competition. This information will help tennis coaches and players to objectify their workloads during training and competitions, as this is usually only an intuitive assessment.

Examining Adolescent Tennis Participation in Contemporary China Using an Ecological Framework.

Physical activity and sport participation behaviors in children and adolescents are consistently shaped by surrounding ecological systems. Accumulating evidence highlights individual, family, peer, school and teacher, and macroenvironment elements such as policies that affect unstructured physical activity choices in youth populations. However, the reason for participation has not been fully interpreted from the perspective of the youth themselves, especially those from an Asian cultural background. In our study, we aimed to better understand the self-identified reasons for adolescents’ participation in non-organized or spontaneous tennis practice in contemporary China. Twenty-six adolescents and informants were recruited in mainland China and participated in semi-structured interviews to provide thick descriptions of their continued tennis participation behaviors. Data were coded and analyzed via NVivo 12. Four themes emerged: (a) Individual characteristics and self-interpretations of tennis culture; (b) microsystems mediating adolescents’ tennis participation; (c) barriers and obstacles impacting tennis participation; and (d) policies and macroenvironments. Adolescent tennis participation is a result of the integration effect of the sociocultural and ecological factors dominated by multifaceted ecological systems. As a particular vision of their physical activity experiences, adolescents’ interpretation of tennis and their broader worldview has been continuously reshaped by concurrent sport and educational policies.

Rainwater Harvesting for Irrigation of Tennis Courts: A Case Study

It has become evident that, during this century, climate change will continue, affecting all regions of the planet. The expected impacts over the next few decades may differ from region to region, with some areas becoming humid and others drier. In regions such as the Mediterranean basin, the main expected impacts of climate change will be prolonged droughts and an increase in the intensity and frequency of heavy rains. Measures of mitigation and adaptation are particularly important in urban environments, where more than half of the population lives, and rainwater harvesting systems (RWHS) are considered to be a very suitable solution to these problems. However, the published studies have mainly focussed on buildings, with very limited references to the interest of its application in large urban infrastructure. Based on consumption and precipitation data, this article presents a study on the implementation of an RWHS in a large-scale sports infrastructure located in the city of Cascais (Portugal) intended for the practice of tennis, with 12 brick dust fields, some of them covered. The average annual consumption of potable water for watering the tennis courts is 5500 m3, and the results show that the RWHS can reduce this consumption by &gt;50%, in addition to other expected benefits, such as the known effect of these systems in reducing flood peaks in the area.

The influence of growth and development on shoulder rotators strength in young male and female elite tennis players.

Tennis practice requires a lot of technical, physical and mental qualities that have to be trained from the youngest age. The important number of hours spent on the court can lead, medium-to-long term to strength or flexibility adaptations, even in the youngest players. The current study aimed to explore the developmental consequences of repetitively playing tennis on shoulder range of motion and shoulder rotators' strength in elite male and female tennis players. Eigthy four painfree elite tennis players were assessed during preseason between 2009 and 2019. Clinical assessment included internal and external rotation range of motion and forward shoulder posture while maximal internal and external rotators strength were assessed with an isokinetic dynamometer in concentric and in eccentric modes (at 60°/s and 240°/s). In male players, growth and maturation induced an increase in forward shoulder posture. Absolute peak torque and bodyweight peak torque of internal and external rotators in concentric and eccentric mode were also significantly increased during with age while ER/IR concentric ratios were significantly decreased. In the female players, only absolute peak torque of internal and external rotators in concentric mode and eccentric strength of external rotators were significantly influenced by the development. Specific adaptations were found in male and female players with age and practice. The important variability in the results within the different age categories and the gender strengthens the importance of regular screening (and isokinetic evaluations) in young tennis players in order to highlight potential atypical profiles, which could have a negative influence on performance or increase the risk of injuries during the development of the player.
