Amaç: Çalışmanın amacı, tenise yeni başlayan gençlerde tenis teknik antrenmanları sırasında ayak bilekleri ve bele takılarak kullanılan direnç bantlarının kuvvet, sürat, çeviklik ve tenis hedefleme performansları üzerine etkisinin belirlenmesidir. Gereç ve Yöntemler: Çalışmaya, yaşları 20,51±2,20 yıl, boyları 175,81±6,73 cm, ağırlıkları 70,56±10,91 kg olan toplam 43 erkek gönüllü olarak katılmıştır. Çalışmada, katılımcılar 3 gruba rastgele yöntemle yerleştirilmiştir. Vücut Ağırlığı Kuvvet Grubu (VAKG)'na, tenis teknik eğitimine ('forehand', 'backhand', 'vole', servis) ek olarak, vücut ağırlıkları ile bacak ve ''core' kuvvetini geliştirmeye yönelik 6 farklı hareket uygulanmıştır (n=15). Tenis Grubu (TG)'na, sadece tenise özgü teknik antrenmanı ('forehand', 'backhand', 'vole', servis vuruşları) yaptırılmıştır (n=11). Direnç Bant Grubu (DBG) ise 'forehand', 'backhand', 'vole' ve servis gibi tenis teknik antrenmanlarını direnç bandı takarak uygulamışlardır (n=17). Tüm gruplara 8 hafta, haftada 3 gün, günde 60 dk antrenman yaptırılmıştır. Tüm katılımcılara, çalışmanın başında ve sonunda olmak üzere antropometrik ölçümler (boy, ağırlık, beden kitle indeksi), izokinetik kuvvet (diz ekstansiyon ve diz fleksiyon), sürat (20 m koşu), çeviklik (altıgen test) ve tenis hedefleme testleri uygulanmıştır. Bulgular: Elde edilen verilerin istatistiksel analizinde, Shapiro-WilkW testi sonuçlarına göre ön-test-son-test karşılaştırmalarında Paired Sample t-testi kullanılmıştır. Tüm parametrelerde zamana bağlı değişimin değerlendirilebilmesi için tekrarlayan ölçümlerde ANOVA yöntemi uygulanmıştır. Tüm grupların önson testleri karşılaştırıldığında, izokinetik diz ekstansiyon, izokinetik diz fleksiyon kuvvet, sürat, çeviklik ve tenis hedefleme performansları arasında anlamlı farklar bulunmuştur (p<0,05;p<0,01). Tüm grupların izokinetik ekstansiyon, izokinetik fleksiyon, kuvvet, sürat, çeviklik ve tenis hedefleme performansı gelişimleri benzer sonuçlar göstermiştir. İzokinetik ekstansiyon parametresinde DBG % gelişimi (%17), VAKG (%16,31) ve TG (%15,01)'den daha fazla bulunmuştur. İzokinetik fleksiyon parametresinde DBG % gelişimi (%19,81), VAKG (%15,95) ve TG (%17,29)'den fazla bulunmuştur. Sürat parametresinde, VAKG (-%8,85), TG (-%5,97) ve DBG (-%7,10) arasında % gelişim, en fazla VAKG'de bulunmuştur. Çeviklik parametresinde VAKG (-%29,19), TG (-%23,01) ve DBG (-%30,85) arasında % gelişim en fazla DBG'de bulunmuştur. Tenis hedefleme testi sonuçlarında ise VAKG (%37,76), TG (%42,64) ve DBG (%44,71) arasında % gelişim en fazla DBG'de bulunmuştur. Sonuç: Tüm grupların kuvvet, sürat, çeviklik ve hedefleme performanslarını benzer geliştirdiği belirlenmiştir. Ancak grupların ölçülen parametrelerinde % gelişimlerine bakıldığında, kuvvet, çeviklik ve hedefleme performanslarının DBG'de, VAKG ve TG'ye göre daha fazla geliştiği bulunmuştur.

ABS TRACT Objective: The aim of this study was to determine the effect of resistance bands used by young beginner tennis players in tennis training by wearing ankle and waist on the strength, speed, agility and targeting performances of tennis. Material and Methods: 43 males (age: 20.51 ±2.20 years; height: 175.81±6.73 cm; weight: 70,56±10,91 kg ) participated voluntarily in the study. In the study, participants divided into 3 groups randomly. The Body Weight Strength Group (BWSG) tennis technical training in addition to (forehand, backhand, volley, service), 6 different movements were applied to improve body weights and leg and core strength (n=15). Tennis Group (TG) had only tennis-specific technical training (forehand, backhand, volley, service beats) (n=11). Resistance Band Group (RBG), on the other hand, applied tennis technical training such as forehand, backhand, volley and service by wearing a resistance band (n=17). All groups were trained for 8 weeks, three days a week, 60 minutes a day. All participants were subjected to anthropometric measurements (height, weight, body mass index), isokinetic knee strength (knee extension, and knee flexion), speed (20 m running), and agility (hexagonal test) and targeting tests in tennis, once in the beginning and once in the end of the exercise. Results: In the statistical analysis of the data obtained, according to the results of Shapiro-Wilk-W test, Paired Samples t-test wasused in the pre-test-post-test comparisons. In order to evaluate the time dependent change in all parameters, was used repeated measures of ANOVA. When compared the pre- and post-tests of the groups, significant differences were found between isokinetic extension, isokinetic flexion strength, speed, agility and targeting performances in tennis (p<0.05;p<0.01). Isokinetic extension, isokinetic flexion strength, speed, agility and targeting in tennis performance developments of all groups have shown similar results. In the isokinetic extension parameter, the percentage of development of RBG (17%) was higher than that of the BWSG (16.31%) and TG (15.01%) group. In the isokinetic flexion parameter, the percentage development of RBG (19.81%) was higher than the percentage development of BWSG (15.95%) and TG (17.29%). In the velocity parameter, the percentage development among the BWSG (-8.85%), TG (-5.97%), RBG (-7.10%) was found most in the BWSG. Percentage development among BWSG (-29.19%), TG (-23.01%), RBG (-30.85%) in the agility parameter was found in the most RBG. In the tennis targeting test results, the percentage development among the BWSG (37.76%), TG (42.64%), RBG (44.71%) was found in the most RBG. Conclusion: It was determined that the strength, speed, agility and targeting performances of all groups developed similarly. However, when looking at the percentage development of the measured parameters of the groups, it was found that the strength, agility and targeting performances improved more in the RBG compared to the BWSG and TG.
