مستخلص: Context: Lateral epicondylopathy (LE) is a common overuse injury affecting elbow, wrist, and hand function. It is characterized by weakness and pain in the muscles and tendons of the forearm responsible for the extension of your wrist and fingers. Trigger point dry needling is a technique reported to be beneficial in managing pain and dysfunction after LE diagnosis. LE is also commonly treated with conservative treatment, such as joint and soft tissue mobilization, self-care home programs, and anti-inflammatory use. We explored a different dry needling approach consisting of in situ dry needling with electric stimulation combined with targeted therapeutic exercise to treat LE in 3 cases. Case Presentation: Three patients were referred for dry needling once a week for 6 weeks and home-based exercise therapy for LE. They were clinically evaluated using grip strength, a visual analog scale to assess pain, and Patient-Rated Tennis Elbow Evaluation Test scores. These were measured at 4 time points (weeks 0, 2, 4, and 6). Management and Outcomes: The dry needling intervention incorporated 8 locations in the upper-extremity with 2 electric stimulation channels. The patients had reduced pain as measured by a visual analog scale, increased function as measured by the Patient-Rated Tennis Elbow Evaluation Test, and increased grip strength over 6 weeks. Conclusions: This case series illustrates the use of dry needling and a home exercise program to provide a favorable outcome in a patient with LE. Patients had an 80% to 100% reduction in pain and similar improvements in function that were significantly beyond the minimum clinically important difference. This dry needling approach is a safe and effective treatment of LE in the short term. [ABSTRACT FROM AUTHOR]

مستخلص: Background: Weakness of the shoulder girdle muscles has been reported in patients with chronic lateral elbow tendinopathy. The aim of this study was to assess the short- and long-term effects of a conventional treatment plus scapular exercises program in patients with chronic lateral elbow tendinopathy. Methods: A single-group prestudy and poststudy were conducted. The primary outcome was the Patient-Rated Tennis Elbow Evaluation questionnaire score. Secondary outcomes were grip strength; Disabilities of the Arm, Shoulder, and Hand questionnaire score; Visual Analogue Scale score at rest and at grip, and presence of scapular dyskinesis. Results: A total of 65 patients (72.3% females), with a mean age of 41.8 years, were analyzed. At the end of 6 weeks, the results showed clinically and statistically significant differences (P< .05). At 1-year follow-up, the differences were: Patient-Rated Tennis Elbow Evaluation -31 points (P<.001); grip strength +33.6% (P<.001); Disabilities of the Arm, Shoulder, and Hand -34.2 points (P < .001); Visual Analogue Scale at rest -2.5 cm (P < .001); and Visual Analogue Scale at grip -2.3 cm (P < .001). Conclusion: At the end of 6 weeks and at 1-year follow-up, conventional treatment plus scapular exercises program showed statistically and clinically significant differences in all functional outcomes assessed in patients with lateral elbow tendinopathy.

مستخلص: Purpose: This study aims to address customer focus as an important component of total quality management (TQM) and explore the key drivers of member satisfaction in tennis clubs via a novel theory-based member satisfaction index (MSI) model with high explanatory and predictive power. Furthermore, the study aims to investigate the relationship between satisfaction and behavioral intentions (willingness to stay; WTS) with consideration of the mediating effect of identification with the club. Design/methodology/approach: This study uses variance-based partial least squares structural equation modeling (PLS-SEM) to estimate the MSI model, which was tested in a leading tennis club in Germany (n = 185). Findings: The results reveal that club atmosphere, club facilities and the price/quality ratio of the membership fee are the most important drivers of member satisfaction in tennis clubs. Member satisfaction has a large influence on the WTS of tennis club members. Identification with the club, when included as a mediator in the model, increases the variance explained in WTS considerably. Research limitations/implications: The small sample limits the generalizability of findings, and further research is recommended. Practical implications: The MSI model is a useful benchmark tool for club managers who want to quantify the satisfaction and WTS of their club members. In addition, because of the integrated formative measurement models, the PLS-SEM results show which indicators can be used to positively impact satisfaction with each of the service quality dimensions, overall member satisfaction and WTS. The most important of these results are discussed in an importance-performance map analysis. Originality/value: The MSI model is a multi-attribute index model through which members' evaluations of various dimensions of service and value are derived through multivariable linear function with each dimension weighted according to its importance in one holistic model. The model shows the strong impact of satisfaction on WTS of sports club members and reveals that findings of previous research on the relationship between fan and spectator identification and loyalty are transferable to sports club members. The MSI represents a new contribution to the literature; it was applied here to tennis clubs but is also suitable for application to other sports clubs. [ABSTRACT FROM AUTHOR]

الملخص (بالإنجليزية): From the point of view of its economic model, the case of tennis is fairly original for several reasons presented in this article. First, the major tournaments play a central role in financing the International Tennis Federation (ITF), and particularly in financing certain national federations such as the French Tennis Federation (FFT). French tennis authorities have been able to keep their major tournaments under their control, and are reaping the benefits. These funds help the regional leagues and departmental committees, which are in a very healthy financial position. On the other hand, the clubs often find themselves in much more precarious situations. With the exception of the most prestigious tournaments, such as those of the Grand Slam, the ATP 1000 and the few ATP 500, professional tournaments get only a small part of their revenues from TV rights and ticketing (stadiums are fairly empty most of the time). Their economic model is based mainly on public relations and partnerships. JEL classification: G30, L31, L983. [ABSTRACT FROM AUTHOR]

Abstract (French): Le cas du tennis est relativement original du point de vue de son modèle économique pour plusieurs raisons présentées dans cet article. D'abord, les grands tournois occupent une place centrale dans le financement de l'International Tennis Federation (ITF) et, particulièrement, de certaines fédérations nationales comme la Fédération française de tennis (FFT). Les instances du tennis français ont su garder la mainmise sur leurs tournois les plus prestigieux et en tirent les bénéfices. Cet argent irrigue les ligues régionales et les comités départementaux, qui sont très sains financièrement, et les clubs qui sont, pour leur part, dans des situations souvent beaucoup plus fragiles. Ensuite, les tournois professionnels – à l'exception des plus importants que sont le Grand Chelem, les ATP 1000 et quelques ATP 500 – trouvent leurs ressources, pour une faible part seulement, dans les droits télévisés et la billetterie (les stades sont clairsemés une grande partie du temps), le modèle étant principalement basé sur les relations publiques et les partenariats.

الوصف: El servei de tenis es considera el cop més complex, potent i determinant en el tennis d'alt nivell. En concret, la velocitat (SV) conjuntament amb la precisió (SA) de servei juga un paper preponderant en competicions d'elit. Considerant que el rendiment del servei està influenciat per diferents tipus de paràmetres, la tesi doctoral es va organitzar per abordar la temàtica d’estudi des d’un enfocament multifactorial. Es va analitzar la influència de variables de naturalesa dispar en la SV i SA en condicions de partit real (estudi I), laboratori (estudi II) i entrenament (estudi III i IV). Per començar, vam determinar la influència de paràmetres antropomètrics, d'impacte i de la ubicació d'aterratge de la pilota en una competició de tennis d'elit (estudi I). Després, vam analitzar les associacions entre SV i diversos paràmetres de la corba força-temps de les extremitats superiors (força isomètrica [IF], taxa de desenvolupament de força [RFD] i impuls [IMP]) en tennistes de competició (estudi II). Finalment, vàrem observar si els mètodes d'entrenament de força isomètrica màxima (IST) i de potenciació postactivació (PAPE) milloren la SV en jugadors de tennis joves (estudi III i IV). Concloem que els paràmetres antopometrics, d'impacte i la ubicació d'aterratge de la pilota influeixen la SV durant una competició professional. Es demostra que els paràmetres de força-temps (IF, RFD i IMP) de les articulacions de les extremitats superiors involucrades en la cadena cinètica de servei influeixen de manera moderada a gran la SV en jugadors de tennis de competició. En concret, la capacitat de desenvolupar força en períodes curts de temps (<250 ms) de l'articulació de l'espatlla es va demostrar que era rellevant per desenvolupar una elevada SV. Finalment, demostrem que la realització d’exercicis basats en la IF de l’articulació de l’espatlla provoca el fenomen de PAPE augmentant el SV sense deteriorament SA. A més, la combinació de 6 setmanes de IST amb els entrenaments habituals produeix augments significatius en la SV sense perjudici de la SA.

En concreto, la capacidad de desarrollar fuerza en periodos cortos de tiempo (<250 ms) de la articulación del hombro fue relevante para desarrollar una elevada SV. Finalmente, se demuestra que la realización de ejercicios basados en la IF de la articulación del hombro provoca el fenómeno de PAPE aumentando la SV sin deterioro de la SA. Además, la combinación de 6 semanas de IST con los entrenamientos de tenis habituales produce aumentos significativos en la SV sin perjuicio de la SA.
Tennis serve is considered the most complex, powerful and determinant stroke in high level tennis competition. Specifically, serve velocity (SV) alongside serve accuracy (SA) plays a preponderant role in elite competitions. Considering that serve performance is influenced by different kind of parameters, the presented doctoral thesis was planned in order to provide a multifactorial approach of the topic of the study. The influence of disparate nature of variables on SV and SA in real match (study I), laboratory (study II) and training (study III and IV) conditions were analyzed. To begin, we determined the influence of anthropometric, ball impact and landing location parameters in elite tennis competition (study I). Then, we analysed the associations between SV and various single-joint upper limb isometric force-time curve parameters (Isometric force [IF], rate of force development [RFD] and impulse [IMP]) in competition tennis players (study II). Finally, we observed if joint-specific post-activation potentiation enhancement (PAPE) and isometric strength training (IST) training methods improves SV in young tennis players (study III and IV). We conclude that anthropometric, ball impact and bounce landing location parameters influence SV during a professional competition. We demonstrate that force-time parameters (IF, RFD and IMP) at different time frames in upper limb joints involved in the serve kinetic chain moderate to very largely influence SV in competitive players. Concretely, the capability to develop force in short periods of time (< 250 ms) in the shoulder joint was shown to be relevant to develop high SV. Lastly, we proved that performing two short upper-limb tennis-specific joint isometric exercises elicits PAPE increasing SV without SA impairment. In addition, combining 6-week of IST with the habitual tennis workouts results in significant increases in SV without SA detriment in young competitive players.

مستخلص: The purpose of the present study was to assess whether the recognition of tennis players' affective state associated with their nonverbal behavior would be influenced by (a) the importance of the situation, (b) the point outcome, and (c) the tennis expertise of the observer. Two hundred sixty-nine participants (Mage = 30.51 years; 116 female; 79 tennis club members) watched video excerpts showing the nonverbal behavior of amateur tennis players during competitive matches immediately after the end of a rally and were asked to estimate whether the player had just won or lost the point. Results indicate that the recognition rates were higher for situations closer to the end of a game, closer to the end of a set, and with a tighter score during a game. Moreover, recognition rates were higher for lost than for won points, while the tennis expertise of participants had no influence on the recognition rates. [ABSTRACT FROM AUTHOR]

مستخلص: In this paper, we analyze the subjective inclusion experiences of visually impaired (VI) adult tennis players from an ableism-critical perspective. The primary focus of this research is the inclusive potential of blind tennis from the perspective of VI individuals. Episodic interviews were conducted to capture subjective perspectives. A qualitative text analysis revealed that the interviewees were confronted with multiple ability assumptions by sighted people in their everyday lives. Deficit notions on the performance of VI people included sports, work, and general activities. Participation in blind tennis helped the interviewees build a "competent identity" and acquire various skills useful for their everyday lives as participation in blind tennis was a pathway for competence in sports. Further research is needed to identify exclusion experiences from the perspective of disabled people to recognize the potential of different sports in reducing barriers to participation.

مستخلص: Purpose: This scoping review aims to identify the primary racket and arm-mounted technologies based on inertial measurement units that enable the quantification of hitting load in racket sports. Methods: A comprehensive search of several databases (PubMed, SPORTDiscus, Web of Science, and IEEE Xplore) and Google search engines was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for scoping reviews guidelines. Included records primarily focused on monitoring hitting load in racket sports using commercialized racket or arm-mounted inertial sensors through noncompetitive and competitive racket-sports players. Results: A total of 484 records were identified, and 19 finally met the inclusion criteria. The largest number of systems found were compatible with tennis (n = 11), followed by badminton (n = 4), table tennis (n = 2), padel (n = 1), and squash (n = 1). Four sensor locations were identified: grip-attached (n = 8), grip-embedded (n = 6), wrist (n = 3), and dampener sensors (n = 2). Among the tennis sensors, only 4 out of the 11 (36.4%) demonstrated excellent reliability (>.85) in monitoring the number of shots hit either during analytic drills or during simulated matches. None of the other racket-sports sensors have undergone successful, reliable validation for hitting-volume quantification. Conclusions: Despite recent advancements in this field, the quantification of hitting volume in racket sports remains a challenge, with only a limited number of tennis devices demonstrating reliable results. Thus, further progress in technology and research is essential to develop comprehensive solutions that adequately address these specific requirements. [ABSTRACT FROM AUTHOR]

مستخلص: Understanding the daily energy expenditure of athletes during training is important to support recovery, adaptation, and the maintenance of performance. The aim of the current research was to assess the total daily energy expenditure (TDEE) and the acute energy expenditure (EE) of tennis training sessions during habitual training of elite tennis players. Using a cohort study design, 27 (n = 10, male; age; 22.3 ± 3.2 years and n = 17, female; age: 23.8 ± 3.5 years) elite singles tennis players were assessed for TDEE and tennis training EE. Using Actiheart activity monitors during a 2- to 5-day training period, male players were analyzed for 26 days and 33 (1.3 ± 0.5 sessions/day) tennis training sessions, and female players for 43 days and 58 (1.2 ± 0.4 sessions/day) tennis training sessions. Male TDEE (4,708 ± 583 kcal/day) was significantly higher than female (3,639 ± 305 kcal/day). Male absolute and relative tennis training EEs (10.2 ± 2.3 kcal/min and 7.9 ± 1.4 kcal·hr⁻¹·kg⁻¹) were significantly higher than those of females (7.6 ± 1.0 kcal/min and 6.8 ± 0.9 kcal·hr⁻¹·kg⁻¹). The resting metabolic rate was assessed via indirect calorimetry. The physical activity level for both groups was 2.3 AU. The TDEE of male and female players during habitual training now highlights the continual cycle of high energy demands experienced by the elite tennis player. The broad ranges of TDEE and EE reported here suggest individual assessment and nutritional planning be prioritized, with a particular focus on carbohydrate requirements. [ABSTRACT FROM AUTHOR]
