Factors that limit the practice of field tennis in the city of Bucaramanga

Introducción: El tenis es un deporte que puede ser practicado de manera individual y colectiva, de vasta complejidad, práctica que cada día cuenta con deportistas más habilidosos, por lo que se pretende conocer las limitantes que tiene este deporte en la ciudad de Bucaramanga. Objetivo: Determinar los factores sociales, económicos o institucionales que limitan la práctica deportiva del tenis de campo en Bucaramanga. Metodología: Fueron seleccionados 40 jóvenes con edades comprendidas entre los 14 y los 18 años de edad, a quienes se les aplicó una encuesta de 19 preguntas relacionadas con la práctica del tenis de campo. Resultados: Con base en las encuestas aplicadas, se halló que más del 97,5% de las personas encuestadas les gusta el deporte, pero solo el 3% practican el tenis y el fútbol predomina con un 50%; la mayoría de los encuestados están interesados en la práctica del tenis, les gustaría poder practicarlo y el lugar más adecuado, según ellos, es en clubes y directamente en la liga de tenis. Conclusiones: Las encuestas aplicadas arrojaron que una de las principales limitantes son la falta de escenarios y de recursos para la práctica del deporte, además que los entes gubernamentales encargados, no brindan suficientes auxilios para poder suplir las necesidades que se presentan en el entorno. Por otra parte, la escolaridad no incentiva desde temprana edad la práctica del tenis, siendo otra deficiencia marcada en el campo.

The effects of perceived competence and self-controlled goal setting on motor learning

PurposeOn the basis of the assumptions that motor learning involves a process in which the learner gains competence on a task, and perceived competence is closely related to the achievement of a goal and the perception of control, this study investigated the effects of perceived competence and self-controlled goal setting on motor learning.MethodsSixty right-handed volunteers, both male (<i>n</i> = 28) and female (<i>n</i> = 32), with an average age of 26.35 years (± 6.29) took part in this experiment. The motor learning task was the field tennis forehand stroke. The experiment involved 2 phases: acquisition and transfer. The acquisition phase consisted of 180 trials performed across 3 days. The transfer test comprised 10 trials under a modified ball flight velocity condition. The participants were divided into 3 groups depending on the level of perceived competence (high, moderate, and low). Furthermore, each group was subdivided into choice (self-controlled goal setting) and yoked groups.ResultsPerformance of the high perceived competence group was superior to that in the low perceived competence group; there was no significant increase in the perception of competence in both groups. Learning was similar for self-controlled and yoked groups.ConclusionsThe findings allow us to conclude that the higher the perceived competence, the better the performance in the acquisition and transfer. Moreover, the control on goal setting did not provide an additional positive effect on motor skill learning in individuals of different levels of perceived competence.

Injuries resulting from practicing performance sports in table tennis and tennis

Performance sport as an area of human excellence requires, besides an over-average genetic endowment of motor skills, a huge workload of high intensity, which causes the wear of the body systems of the athletes, especially the osteo-musculo-articular. The high ball movement speed for rocket and paddle sports disciplines such as table tennis and field tennis, intensively demands the performance of the body of practitioners when performing specific technical tactics, especially the technical elements of the attack, such as topspin or smash. Based on the theoretical documentation, I noticed an acute condition in the scapulo-humeral joint 21.05%, at the lumbar level 15.79% and 13.16% in the ankle joint in the table tennis and in the field tennis as percentages at scapulo-humeral joint 13.85%, lumbar 15.38% and 20.00% ankle joint, aspects that validate our desire to improve the quality of life of practicing athletes of the two disciplines through a program of amelioration of compensatory nature.The objective of this theoretical research is to identify the areas subject to mechanical stress with high risk of wearor injury from the two "sister" sports disciplines.Tasks: Critical analysis of a larger volume of studies conducted on the direction of our research interest.Purpose: obtaining the information necessary which would highlight the risks the performance athletes, practitioners of the two disciplines, are subjected to, as well as gaining knowledge on tennis and table tennis.

PSYCHOMOTOR AND COGNITIVE SKILLS THAT MAKE A DIFFERENCE IN TENNIS PLAYERS AT NATIONAL LEVEL

Tennis has become an extremely complex sport, with tennis players needing a team of specialists to maximise their sports performance. Performance tennis has proven that the difference between the players, in the conditions of similar technical-tactical performances, is made by the physical and mental training. Our paper aimed to investigate the subjective reality of junior tennis players in order to optimise their actions and activities by identifying a psychomotor and cognitive model of athletes ranked in the top area nationally. The research involved 75 tennis players - 40 boys and 35 girls aged between 14 and 16 years. The materials used were represented by the PSISELTEVA psychological testing system developed by the RQ Plus Company and calibrated to the Romanian population, which contains: levers, desk with buttons, pedals. The tests belonging to the computerised battery used in the research are: TRS (simple reaction time), TRD (discrimination reaction time), RCMV (intersegmental coordination), TUD (eye-hand coordination), ANALOGIE (analogical transfer), TAC (attention concentration), MT (topographical memory) and RNE (resistance to mental fatigue). Through the Mann-Whitney (U) test, significant differences were identified between the first tennis players in the national ranking and the players placed in the middle or final zone of the ranking, in terms of different psychomotor and cognitive coordinates (investigated in various environmental conditions). The results obtained are useful both for specialists working in the field of tennis (coaches, sports psychologists, physical trainers), athletes (boys and girls) aspiring on the road to great performance, but also for sports clubs.

Pengaruh Latihan Stroke ke Dinding dan Latihan Stroke Berpasangan terhadap Keterampilan Forehand Groundstroke pada Peserta UKM Tenis Lapang UNSIL Kota Tasikmalaya

Forehand Groundstroke in a tennis game is a stroke that aims to defend or attack. To master the Forehand Groundstroke technique, the authors tried two training methods, namely the method of stroke to wall training and pair stroke training. The purpose of this study was: to find out the difference in influence between stroke to wall exercises and paired stroke exercises on Forehand Groundstroke skills in tennis. Referring to the purpose of the study and to prove the hypothesis, the author uses the experimental method. The population consisted of students from the field tennis UKM in UNSIL, Tasikmalaya City, which numbered 27 people. Samples were taken as many as 20 people using random (random) techniques. The research instrument used to obtain the data was Hewitt tennis achievement from Jack E. Hewitt. Based on hypothesis testing, t arithmetic is outside the interval t table, namely t arithmetic <t 0.995 (18) = -4,500 <2,878. So there was no significant difference from the results of the two groups' exercises, namely group A (stroke to wall exercises) and group B (paired stroke exercises). So that stroke-to-wall exercises and paired stroke exercises have the same effect on Forehand Groundstroke skills in tennis games for students in field tennis UKM UNSIL Tasikmalaya. Thus the null hypothesis is accepted, and the alternative hypothesis is rejected. But based on the results of the average increase it is known that group B has a greater increase than group A.

A tennis field test to objectively measure the hitting accuracy based on an Excel spreadsheet: Practical guidelines and applications

Stroke accuracy is highly related with tennis performance and has traditionally been quantified using general areas of scoring. Hence there is a need to develop methods that allow accuracy to be measured with higher resolution. The aim of the work is to develop a field test and an Excel spreadsheet associated that allows to evaluate the accuracy of the strokes with a resolution up to centimetres and to study how shots landings are distributed. The test consists of 4 series of 20 groundstrokes performed in the down the line or cross-court direction (this is modifiable). The 2D coordinates of bounce of the ball is recorded with a camera, digitalized using a specialized software and introduced in the Excel spreadsheet. Then it computes a series of parameters that describe the 95% confidence ellipse of the shot landing on the court. A real example of the test outcomes of two advanced players - performing forehands and backhands down the line- is shown. Consistent with previous literature both players obtained a better accuracy in the mediolateral direction than in the longitudinal direction and ellipses were oriented almost parallel to the sideline (ellipse tilts were below 12 degrees in all cases). Ellipse area was considerably greater for the backhand than for the forehand in player two (38.8 vs. 55.5 m2) but not in player one (51.5 vs. 50.8 m2). Finally, the centre location of the ellipse in the longitudinal axis was positive in all cases (near 200 cm) which suggest that both players preferred to make short shots rather than send the ball out of the limits of the baseline. We conclude that this methodology can be used by researchers that want to assess accuracy with high resolution and by coaches that want to evaluate -with high sensibility- the player progression after a training program.

PENGARUH PEMBERIAN MINUMAN ISOTONIS DAN PISANG TERHADAP KADAR GLUKOSA DARAH ATLET TENIS LAPANGAN UNIVERSITAS NEGERI PADANG

The problem in this study is that many athletes do not pay attention to nutrition and drinks consumed while playing tennis. It is feared that it can affect performance when competing, so it is necessary to do research on the nutrition and drinks consumed by field tennis athletes at Padang State University.
 This study aims to determine the effect of giving isotonic drinks and bananas on blood glucose levels in tennis tennis athletes. The research method used was an experiment with the same subject design (treatment by subjects designs). The population in this study were tennis athletes in Padang State University totaling 35 people. The research sample of 20 male tennis athletes taken by purposive sampling technique. The instrument for measuring blood glucose levels uses the Glucometer. The data analysis technique used is ANOVA (one way) at a significant level α = 0.05. The results show that isotonic and banana drinks during playing tennis have not been able to maintain blood glucose levels, as evidenced by differences in blood glucose levels before and after playing tennis. Isotonic drinks are better at maintaining blood glucose levels after playing tennis compared to bananas with a significant difference (p <0.05).

A Smart Analysis of Technical Skills of Top Male Table Tennis Players

ABSTRACTThe purpose of this study was to evaluate technical skills of top male table tennis players in the world in 2017. Subjects used for this study were top four male table tennis players who got into the semifinal more times than other players during both 2017 International Table Tennis Professional Tour and World Table Tennis Championships. Data collected were analyzed statistically using percentage, regression, and assessment methods that were designed specially for table tennis. The following three points could be concluded: (1) From the overall technical analysis of four top players, it showed that they got the ‘pass’ grades in score percentage and usage of the three-staged techniques. Ma Long and Fan Zhendong in particular got the ‘excellent’ grades. Technical skills of these four top players were versatile. Their styles of play were unique; all of them received excellent in the evaluation of three-staged techniques. (2) ‘Attack after serve’ technique was the main technical skill used to play and score the points throughout the game by Ma Long and Fan Zhendong. Ovtcharov only got the ‘good’ grade in ‘attack after serve’, but got the ‘excellent’ grades in both ‘attack after receive’ and ‘rally’. Because of his excellent skill in ‘attack after receive’ and ‘rally’, he was well known in the field of table tennis throughout the world. Xu Xin got the ‘pass’ grade in ‘rally’. Even though Xu Xin showed excellent performance in three-staged techniques, he was no better than other players. In the future, Xu Xin should improve his stability and score percentage in ‘rally’ in order to get better results. (3) Serve, attack after serve using forehand stroke, attack after receive using backhand stroke, continuous forehand stroke attack, and continuous backhand stroke attack were the main technical skills which could be used to predict the result of the game for winning 2017 World Table Tennis Championships in men’s single event.

Wheelchair mobility performance of elite wheelchair tennis players during four field tests: Inter-trial reliability and construct validity

The purpose of the current study was to assess the inter-trial reliability and construct validity (talented juniors vs. international adult players) of four wheelchair tennis field tests using inertial measurement units (IMUs). Twenty-one elite wheelchair tennis players completed four tests, which evaluate the sprinting and manoeuvrability abilities in wheelchair tennis. During all tests 3 IMUs were attached to both wheels and the frame of the athlete’s wheelchair. The IMUs enabled analysis of individual test dynamic characteristics, i.e. the linear/rotational velocity and acceleration data, as well as detected pushes. All tests showed high ICCs (0.95–0.99) for the inter-trial reliability for the IMU-based end times and also the construct validity was good, i.e. talented juniors could be discriminated from international adults. Also, velocities and accelerations during the tests could be consistently visualized, meaning that differences in test performance among participants could be designated. Within the experimental context, the field tests could be regarded as reliable and valid. With the use of IMUs it is possible to verify more detailed performance characteristics, visualize the test execution, as well as differentiate between a talented junior and international adult group and within individuals over time.

The impact of psychological traits on performance in sequential tournaments: Evidence from a tennis field experiment

Extant research has analyzed the impact of player position (first- versus second-mover) on individual performance in sequential tournaments. However, it remains unclear whether the first- or second-mover experiences an advantage in such tournaments. We argue that prior literature has ignored heterogeneity of psychological traits and incentive schemes. We conducted a tennis field experiment using the ABBA sequence, in which we do not find a first- or second-mover advantage on game level. However, on shot level (taking into account single moves) we observe, on average, a second-mover advantage. Analyzing the impact of psychological traits, we find that subjects with high self-esteem faced a second-mover advantage whereas subjects with low self-esteem faced a first-mover advantage on shot level. We do not observe significant moderating influences of individual, team, or tournament incentive schemes.

EFEKTIVITAS PELAYANAN PSIKOLOGIS TERHADAP LANJUT USIA (Studi Kasus Pada UPTD Pusat Pelayanan Sosial Lanjut Usia Mappakasunggu Parepare)

This research is qualitative descriptive by conducting interviews, observing and documenting to produce descriptive data in the form of words, written, or oral, and observed behavior. The results showed that 1) the elderly background had a glorious period of employment status as soldiers, civil servants and field tennis athletes, but with neglected and vulnerable conditions they experienced so they could prevent their psychological state. 2) Forms of services used in psychological services in the elderly in the form of group counseling and therapy with spiritual guidance which is a process carried out through Islamic psychotherapy, and mental fitness therapy and skill guidance. 3) The effectiveness of psychological services is said to be effective seeing from the effectiveness theory which shows the success in terms of achieving the target actions which are determined by meeting the needs of abraham maslow needs with the results that the elderly feel more secure and comfortable with holding consultations every day, feeling more cared for by mentoring from the coach who always visit their guesthouse, feel more self-respect because they are still able to do gymnastic activities and skill guidance, and with spiritual guidance can give them inner peace and bring closer to Allah SWT. Thus, it can be concluded that the effectiveness of psychological services in the UPTD of the elderly social service center, while waiting for Parepare to be effective, has seen from the benchmark of the theory of effectiveness and the fulfillment of elderly needs that they feel more comfortable in their homes than in their own homes. However, it is still less effective when viewed in terms of group consultation and therapy room facilities, as well as limited therapeutic equipment.

Conclusion: It can be utilized as a useful tool in predicting the self-efficacy of tennis players. It is deemed that there is a need to assess the effects of tennis player and self-efficacy by investigating the relationship among a diverse range of sports variables with the inventory developed in this Study in the future.

Kontribusi Kekuatan Genggaman terhadap Akurasi Servis Flat Atlet Tenis Lapangan Universitas Negeri Padang (PTL UNP)

The problem with this research is the low accuracy of the flat service of the tennis player when playing, meaning that the flat service punch done by the player is merely hitting the ball into the opponent's service area but does not have clear direction and goals. The low accuracy of flat servicing can be influenced by the grip strength factor, so in this study the authors aim to explain the contribution of grip strength to the accuracy of flat servicing of the tennis court of the State University of Padang (PTL UNP). This research is correlational, which is to find out how much the relationship between variables and contributions made from the independent variables to the dependent variable. The population in this study was the tennis court players in the Padang State University (PTL UNP) Field Tennis Training club and for purposive sampling technique for sampling. To measure the strength of the grip using a dynamometer handgrip tool, while the accuracy of flat service by performing the Hewwit Tennis Achievement Test. So from the results of this study concluded that the accuracy of flat service is influenced by the strength of the grip

The Impact of Psychological Traits on Performance in Sequential Tournaments: A Field Experiment

In order to analyze if heterogeneity in psychological traits affects individual performance in sequential tournaments, we conducted a tennis field experiment. In the experiment, we also varied the payment schemes (individual, team, competition) to control for moderating effects of different incentives. Team incentives, risk taking, and self-esteem reduced performance whereas a preference towards competition enhanced it. On average, we observe a second mover advantage. However, individuals’ psychological traits, such as self-esteem or self-efficacy, can turn a second mover into a first mover advantage. Our results shed new light on the discussion of first vs. second mover advantages and performance under pressure. Study findings have implications for psychological requirements of competitive and team tasks in business settings.
