Not only aerobic exercises, but also resistance exercises program with maximum effort for large muscle groups such as squat has also been reported to be effective on muscle and body fat mass. Thus, this study aims to investigate the effect of squat exercises program on body composition. The data of this study were collected from 18 young adult males in July 2019 after 8 weeks of training. Workouts were held in 3 days in a week with the 48 hours resting interval. Each session consists of 4 sets of 6 repetitions squat exercises with the loads of 85% maximum strength. Independent t-test analysis was used in binary comparisons because of normal data distribution. The results of this study were not statistically significant with the increase in body weight, body mass index, total muscle weight, total body fluid weight and lean body mass and the decrease in total fat weight variable as a result of the 2-month squat strength training program. Only a significant decrease in body fat percentage by 7.15% was observed after two months squat training. In conclusion, it was proposed that the squat exercises as a resistance training program can be used effectively in decreasing body fat ratio and increasing muscle mass due to increased post-exercise oxygen consumption in aerobic metabolism supplying energy from fats mostly.

Bu araştı rmanın amacı elit sporcularda anaerobik dayanıklılık ile dikey sıçrama arasındaki ilişkinin incelenmesidir. Araştı rmaya elit seviyede, iki farklı branşta (boks n=6, hentbol n=8) toplam 14 gönüllü erkek sporcu katı lmıştı r. Araştı rmaya katı lan sporcuların, yaş ortalamaları; 20,25±1,03 yıl, boyları; 1,80±0,08 m, vücut ağırlığı ortalamaları; 77,14±18,91 kg, spor yaşı ortalaması; 9,87±3,31 yıl, milli olma sayıları ortalaması; 10,0±3,31'dir. Araştı rmada dikey sıçramanın belirlenmesi için smart speed lite sistemi, Anaerobik dayanıklılık belirlenmesinde ise üç köşe koşu testi kullanıldı. Tüm sporcuların kalp atı m sayıları; ısınmadan önce, ısınmadan sonra ve anaerobik dayanıklılık koşu testi nden sonra polar saat kullanılarak kaydedildi. Anaerobik dayanıklılık ve dikey sıçrama performansları arasında anlamlı ilişki olduğu tespit edilmiş olup (p<0,05), dikey sıçrama yeteneği iyi olan sporcuların aynı zaman da anaerobik dayanıklılıklarının da iyi olduğu kanaati ne varılmıştı r. Sonuç olarak, dikey sıçramanın anaerobik dayanıklılığı 0,34 oranında açıkladığı ve dikey sıçramadaki 1 birimlik değişimin anaerobik dayanıklılığı 0,21 oranında etkilediği bulunmuştur.Anahtar Kelimeler: Anaerobik dayanıklılık, dikey sıçrama, spor ASSOCIATION BETWEEN ANAEROBIC ENDURANCE AND VERTICAL JUMP ABSTRACTThe aim of this study was to examine the association between anaerobic endurance and vertical jump in elite athletes. A total of 14 elite male athletes from two different branches (boxing n = 6, handball n = 8) participated in the study. Average age of the athletes who participated in the study was 20.25±1.03 years, while average heights were 1.80±0.08 cm, average body weights were 77.14±18.91 kg, average years of doing sports was 9.87±3.31 years and the average number of playing in a national team was 10.0 ± 3.31. Smart speed lite was used to determine vertical jump while 3 corner running test was used to determine anaerobic endurance. Heart rates of all athletes were measured before warm up, after warm up and anaerobic endurance test by using a Polar watch. Significant association was found between anaerobic endurance and vertical jump performances (p<0.05) and it was concluded that athletes with good vertical jump skills also had good anaerobic endurance. As a conclusion, it was found that vertical jump explained anaerobic endurance with a rate of 0.34 and one unit change in the vertical jump influenced anaerobic endurance at a rate of 0.21.

Bu araştırmanın amacı adölesan kadın voleybolcularda 8 haftalık bosu denge ve kuvvet egzersiz programının (BDKEP) vücut kompozisyonu, anaerobik güç ve denge yeteneğine etkisini tespit etmektir. Araştırmaya, Adana Volem Spor Kulübünde oynayan lisanslı 14 - 16 yaş gruplarından 15 deney (14,87 ± 0,92) ve 15 kontrol grubu (14,93 ± 0,70) olmak üzere toplam 30 voleybolcu katılmıştır. Kontrol grubu sporcuları sezon içerisinde düzenli olarak voleybol antrenmanlarını sürdürürken, deney grubuna ekstra 8 hafta boyunca haftada üç gün bosu denge ve kuvvet egzersiz programı uygulanmıştır. Veriler elde edilirken flamingo denge, dikey sıçrama ve durarak uzun atlama testleri uygulanmıştır. Deney ve kontrol grubunun ön test-son test ölçümlerde Paired Samples t-testi, antrenman etkisi ile fiziksel ve kondisyonel özellikler arasındaki ilişkinin incelenmesinde Pearson Korelasyon analizi yapılmıştır. Çalışma sonucunda deney grubunun 8 haftalık bosu denge ve kuvvet egzersiz programından sonra boy uzunluğu, vücut ağırlığı, beden kitle indeksi ortalama değerlerinde anlamlı bir artış gözlenmemiştir (p&gt;0,05). Deney grubunun flamingo denge sağ ve sol ayak, durarak uzun atlama, dikey sıçrama ve anaerobik güç ortalamalarında Cohen's d analizleri sonuçlarına göre orta düzeyde bir gelişme gözlenmiştir. Kontrol grubunda ise 8 haftanın sonucunda bir değişim görülmemiştir. Sonuç olarak bosu egzersizlerinin voleybolcularda denge ve kuvvet gelişimine etki ettiği tespit edilmiştir. Denge ve kuvvet gelişimi için bosu egzersizleri antrenman programının içerisine dahil edebilir.

Aim: This study was designed to determine whether caffeine supplementation applied at different times has an effect on vertical jump and long jump performance. Method: The study group consists of a total of 30 healthy and volunteer elite male athletes. Caffeine supplementation was applied to the elite athletes participating in the study in two separate periods, and three groups were randomly formed as the first group (Experiment 1), the second group (Experiment 2), and the no application (Placebo) group. Athletes in the (Experimental 1) group were given caffeine supplementation, 60 minutes before the measurements, and the athletes in the (Experiment 2) group were given 6 mg/kg powdered caffeine supplement, mixed with 250 ml of water, 120 minutes before the measurements. Only water was administered to the (placebo) group. In the study, the smart speed lite system was used to determine the vertical jump, and the standing long jump test protocols were used to determine the long jump. Differences between groups were determined by using a post-hoc LSD test together with the one-way analysis of variance in (One-Way-ANOVA-post-hoc LSD) in accordance with the experimental design of the study. Results: Considering the vertical jump and long jump pre-test post-test performances of the participants, there was a general increase in all groups. There was no statistically significant difference between the posttest-pretest difference scores of vertical jump and standing long jump performance values (p>0.05). Conclusion: Both results were found to have low effect size values. Keywords: Caffeine, Vertical Jump, Long Jump, Athletic Performance
