Rest interval between sets in resistance exercises is an important variable that influence on the training volume. The purpose of the current study was to determine the effect of static stretching on the number of repetitions for three consecutive sets upper and lower body exercises. Nine trained men (age: 21,78±2,49 years; height: 171,5±4,62 cm; weight: 73,98±6,62 kg; body fat percentage: 11,1±3,95 %) completed three sets push down and leg extension exercises with 10 repetition maximum, %60 of 1 repetition maximum and %85 of 1 repetition maximum load. Participants took part static stretching and non-stretching conditions that was done on counterbalance. The results of this study demonstrated that the number of repetitions significantly decreased after static stretching for both exercises at all intensities. When compared the two conditions, the number of repetitions after static stretching on set 2 and set 3 was significantly lower than the set 1 for push down exercise at all intensities. However, for leg extension exercise at 10 repetition maximum intensity on set 2 was significantly lower than the set 1 and at %85 of 1 repetition maximum intensity on set 2 and set 3 significantly lower than the set 1. There is no significant difference for leg extension exercise between groups at %60 of 1 repetition maximum intensity. In conclusion, this study indicated that static stretching between consecutive sets has negative effect on the number of repetitions for push down and leg extension exercises. Therefore static stretching should be avoided during the rest period between sets when performing the push down and leg extension exercises.

The purpose of this study was to develop a scale to identify the weight loss methodology preferred by athletes and to determine the effect of the chosen weight loss methodology on themselves. On this purpose,

Yapılan bu çalışmanın amacı iki farklı ortamda yapılan (karada ve suda) dayanıklılık antrenmanının vücut sıvı miktarı üzerine etkilerinin incelenmesidir. Bu çalışmaya yüzme eğitimi almış [(̅ +) yaş: 20,06±1,91 yıl; boy: 178,06±7,84cm; vücut ağırlığı: 72,87± 6,91kg; vücut yağ yüzdesi: 9,94±3,18] olan 16 erkek sporcu gönüllü olarak katılmıştır. Çalışmada sporcular rastgele örneklem seçim yöntemi ile 2 eşit gruba ayrılmış (8 kara antrenmanı gurubu, 8 su içi egzersiz grubu) ve 15 dakikalık ısınma ile birlikte toplam 2 saat dayanıklılık antrenmanı uygulamıştır. Çalışmada ilk uygulamalar tamamlandıktan sonra 24 saat ara verilmiştir. Sonrasında kara antrenman grubu su içi egzersiz, su içi egzersiz grubu ise kara antrenmanı uygulamıştır. Bu esnada iki saatlik dayanıklılık antrenmanı öncesi ve hemen sonrası vücut kompozisyonu ölçümleri (vücut ağırlığı, vücut sıvı miktarı, kas kütlesi vücut yağ yüzdesi), idrar yoğunluğu ve vücut sıcaklığı ölçümleri yapılmıştır. İstatistiksel analizlerde eşleştirilmiş örneklerde t-testi kullanılmıştır. Yapılan istatistiksel analiz sonucunda vücut ağırlığı, vücut sıvı miktarı, kas kütlesi, vücut yağ yüzdesi ve vücut sıcaklığı değerlerinde anlamlı fark olduğu (p<0,05), idrar yoğunluğunda ise istatistiksel olarak anlamlı bir fark olmadığı (p>0,05) belirlenmiştir. Sonuç olarak her iki ortamda da yapılan dayanıklılık egzersizlerinde vücut sıvı miktarı, kas oranı ve vücut sıcaklığı değerlerinde istatistiksel olarak önemli değişiklikler olduğu tespit edilmiştir.

Aim: The purpose of this study is to ascertain the knowledge, attitudes, and behaviors of students studying in the Coaching Education Department of the Faculty of Sport Sciences regarding the utilization of nutritional ergogenic supplements. Methods: 61.5% of the participants were male (n=264), 38.5% (n=166) were female. Data were collected by conducting an online questionnaire. 19.5 % of students reported using ergogenic nutritional supplement products. The students received an average score of 3.1±0.7 on the benefit sub-dimension of the attitude scale toward nutritional ergogenic supplement products, 2.7±0.6 on the side effects and ethical sub-dimension, and 2.9±0.7 on the natural nutrition sub-dimension. Results: A significant difference has been detected in the mean scores of students on the benefit sub-dimension depending on their gender, sports branch, and use of nutritional supplement products, on the side effects and ethical sub-dimension depending on their gender, class, and use of nutritional supplement products, and on the natural nutrition sub-dimension depending on their gender and use of nutritional supplement products (p<0.05). Conclusion: Students gave the expected answer to most of the questions regarding the use of nutritional ergogenic supplements. Observing the beneficial effect of taking the sports nutrition course on the responses, reveals the importance of education once again.
