EFFECTS OF ATHLETE PERSONALITY ON VARIABLES RELATED TO TENNIS INJURIES

This research aims to investigate how tennis players' personality structures affect some variables related to the injuries they experience in sports. The research population consists of tennis players between the ages of 10-18 in Turkey. A total of 158 (female: 87, male: 71) tennis players between the ages of 10-18 who had at least one tennis-specific injury participated in the study. Demographic questions (gender, age, height, weight, time of sports injury, repetition of the same injury, and injury measure) used in the study were created by the researchers. The personality of the athlete was determined by the athlete himself, and the survey questions were determined by using the survey questions used in Kirişci's (2011) study. Data from tennis players were collected online via 'Google Form'. There is a low level of statistically positive correlation between re-experiencing the sports injury and the time of the sports injury (r=0.18, p=0.03). There is a low level of statistically positive correlation between the gender of the participants and taking precautions for sports injury (r=0.20, p=0.01). There is a low negative correlation between the gender of the participants and their athlete personality (r=26, p=0.001). There is no statistically significant difference between the participants' re-experiencing the same injury, taking precautions in sports injury, and athlete's personality (r=-0.013, p=0.87, r=0.010, p=0.90). It can be said that the sports injuries experienced by tennis players are related to their personality types and their gender. It can be said that injuries seen in tennis sports are more common during matches and women take more precautions for sports injuries than male athletes. In addition, it can be said that female athletes have both courageous-attentive and emotional-calm personality types, while males have the most courageous-active personality type.  Article visualizations

Hit turn tenis testi ve modifiye edilmiş hit turn tenis testinde kalp atım hızı toplam mesafe ve algılanan zorluk derecelerinin karşılaştırılması

06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Hit Turn Tenis Testi ve Modifiye Edilmiş Hit Turn Tenis Testinde Kalp Atım Hızı Toplam Mesafe ve Algılanan Zorluk Derecelerinin Karşılaştırılması Giriş ve Amaç: Hit-turn tenis testi ve modifiye edilmiş hit-turn tenis testinde kalp atım hızı, toplam mesafe ve algılanan zorluk derecelerinin karşılaştırılması olmuştur. Materyal ve Yöntem: Araştırmamıza dâhil edilen 30 erkek sporcunun yaşları 13,07 ± 1,65 yıl, boy uzunlukları 1,60 ± 0,14 cm, beden ağırlıkları 46,88 ± 10,14 kg, antrenman yaşları 6,56 ± 1,71 yıl ve haftada 5.7 ± 0.4 saat antrenman yapmaktaydılar. Çalışmaya katılan 12 kız sporcunun yaşları ise 13,07 ± 1,65 yıl, boy uzunlukları 1,60 ± 0,16 cm, beden ağırlıkları 52,32 ± 14,12 kg, antrenman yaşları 6,90 ± 1,40 yıl ve haftada 5.7 ± 0.4 saat antrenman yapmaktaydılar. Her bir sporcu hem hit-turn tenis testini orijinalinde olduğu gibi sabit duran toplara karşı, hem de bu testi modifiye ederek karşıdan gelen toplara karşı vurarak gerçekleştirmişlerdir. Her iki test uygulanırken hem kız hem de erkek sporcuların toplam koştukları mesafeler, kalp atım hızları ve algıladıkları zorluk dereceleri kayıt edilmiştir. Her iki test arasındaki farklılığı bulmak için parametrik olmayan düzende wilcoxon testi uygulanmıştır. Bulgular: Testler esnasında sporcular Hit-Turn Tenis testinde Modifiye Hit-Turn Testine oranla erkeklerde 104 m kızlarda ise 160 m daha fazla mesafe kat etmişlerdir. Bu fark istatistiksel olarak erkeklerde (z:-2,071; p 0,05). Sporcuların her iki testi de algıladıkları zorluk derecelerine baktığımızda Modifiye Hit-Turn Testi sporcular tarafından daha zorlayıcı olarak bulunmuştur. Sonuçlar: Modifiye Hit-Turn Tenis testinde sporcular filenin diğer tarafından gelen toplara vurmak için, sabit duran toplara yaptıkları vuruşlardan daha fazla güç harcadıkları düşünülmektedir. Ancak fazladan kullanılan bu güç kalp atım sayısını etkilememektedir. Anahtar Kelimeler: Tenis, Kalp Atım Hızı, Hit-Turn Tenis Testi, Aerobik Kapasitede, Dayanıklılık.Comparing Heart Rate Total Distance and Perceived Difficulty Grades in Hit Turn Tennis Test and Modified Hit Turn Tennis Test Introduction and Aim: The hit-turn tennis test and the modified hit-turn tennis test have compared heart rate, total distance and perceived difficulty ratings. Materials and Methods: The age of 30 male athletes included in the study were 13,07 ± 1,65 years, height length 1,60 ± 0,14 cm, body weights 46,88 ± 10,14 kg, training ages 6,56 ± 1, 71 years and 5.7 ± 0.4 hours per week. The ages of 12 girls participating in the study were 13,07 ± 1,65 years, height length 1,60 ± 0,16 cm, body weights 52,32 ± 14,12 kg, training ages 6,90 ± 1,40 years and weekly 5.7 ± 0.4 hours of training. Each athlete has performed both the hit-turn tennis test against the stationary set as well as the original, and also by modifying this test against the opposing crowd. When both tests were performed, the total distance of both male and female athletes, distance of heart rate, and difficulty ratings they perceived were recorded. A nonparametric linear Wilcoxon test was applied to find the difference between the two tests. Results: During the tests, the athletes had more than 160 m in the Hit-Turn tennis test and 104 m in the boys compared to the Modifiye Hit-Turn test. This difference was statistically significant in males (z: -2,071; p 0,05). When we looked at the difficulty levels that the athletes perceive in both tests, the Modified Hit-Turn Test was found to be more challenging by the athletes. Conclusıons: In conclusion, in the Modified Hit-Turn Tennis test, the athlete is expected to spend more power to hit the ball from the other side than from the striking ball. However, this extra power does not affect the number of heart beats. Key words: Tennis, Heart Rate, Hit-Turn Tennis Test, Aerobic Capacity, Endurance

An examination of the effect of 'Hit-Turn Tennis Test' on two different protocols in pre-pubertal tennis players to heart rate, total distance runned and perceived difficulty

Aim: The aim of the research, Hit-Turnu Tennis test, fixed with punches against the top of this test modified by downloading thrown my heart made on kick against the top speed is defined as the total requirement distance and examine the impact of the perceived difficulty.Material and Methods: The ages of the athletes were included in our study 12.7±1.75 years, height of 155.2±3.1 cm, body weight 50.9±4.78 kg, training age was determined they did was 6.7±1.5 years and a week was 5.7±0.4 hours of training. Every athlete and tennis Hit-turn test against a stationary ball, as in the original, but they also perform this test by hitting the ball against oncoming traffic by modifying. Both tests from applying their athletes run totals, heart rate and difficulty during tests perceive degrees were recorded. After the data collected during both tests calculated descriptive statistics, the differences between the differences between the two groups paired t-test to examine test (paired-samples) were analyzed.Results: Hit Tennis athlete-turn test during the test, the modified test Hit-turn compared to 124 m They travel a greater distance. This difference was statistically significant (t:2.915; p<0.006). In addition, heart rate values are observed to be similar to each other when both tests. When we look at both testes of athletes perceived degree of difficulty Modified Hit-turn test it was found to be more compelling by athletes. Conclusion: As a result, the modified test Hit-Turn tennis athletes to hit the balls by other net, than they do to kick a stationary ball is believed to spend more effort

Adolescent tennis players' injury profile and awareness level of sports injury

Objective: The aim of this study is to examine the relationship between injury risk profile and injury awareness, as well as the level of injury knowledge and the incidence of injuries among adolescent tennis players. Material and Methods: One hundred seventy-nine adolescent tennis players (n: 98 females and 81 males, age: 13.9±1.6 years), who had a history of at least one sports injury were included in the study. A questionnaire was designed by sport experts that questioned about the tennis injuries and awareness of tennis injuries. Results: The most injured area was the shoulder (22%). It was followed by elbow (19%), ankle (17%), wrist (16%), and the knee (12%). Experiencing more sport injuries (more than twice) increased 5.7 times (p<0.01) if they had medium knowledge level, and increased 22.4 times if they had low knowledge level (p<0.001). Conclusion: Upper extremity injuries are more common in adolescent tennis players comparing with lower extremity injuries. In addition, the number of previous tennis injuries was related to training load and the athletes' awareness of tennis injuries. Therefore, optimizing tennis training load and increasing the level of injury awareness in adolescent tennis players may be important in preventing future sports injuries
