Üst Gövde Direnç Egzersizlerinde 1TM, 5TM ve 10TM Testlerinin Güvenirliği

Öz

Spor bilimlerinde antrenman ya da benzeri bir müdahalenin etkisini inceleyen araştırma tasarımları yaygın olarak kullanılmaktadır. Bu tür tasarımlarda katılımcıların ön test ya da son testlerinden elde edilen verilerin güvenirliği oldukça önemlidir. Bu çalışmanın amacı üst gövde egzersizlerinde (bench press, shoulder press, biceps curl ve triceps extension) 1TM (1 tekrar maksimum), 5TM ve 10TM testlerinin güvenirliğini incelemektir. Çalışmaya antrenman deneyimi düşük (1 yıl ve daha az) seviyede olan 23 gönüllü erkek katılmıştır. Katılımcılara bir alıştırma antrenmanından sonra dört farklı egzersizin 1TM, 5TM ve 10TM testleri üç-dört gün arayla ikişer kez uygulanmıştır. İki ölçüm arasındaki farklar ve test-tekrar test güvenirliği analiz edilmiştir. Araştırmanın bulgularına göre toplam 12 testten, ikisinde (biceps curl 1TM ve triceps extension 1TM) ölçümler arasında anlamlı fark bulunurken, diğer 10 testte ölçümler arasında anlamlı fark bulunmamıştır. Testlerin güvenirliğinin belirlenmesi ve diğer çalışmalar ile karşılaştırılması için sınıf içi korelasyon katsayısı (ICC): 0,945-0,993; değişim katsayısı (CV): %1,25-3,33; ölçümlerin tipik hatası (TEM): 0,84-2,25; minimum anlamlı değişim (SWC): 0,97-2,25; Pearson korelasyon katsayısı (r): 0,919-0,988; Etki boyutu (ES): 0,01-0,34 olarak hesaplanmıştır. Sonuç olarak 1TM, 5TM ve 10TM testlerinin tamamının güvenilirlik analizlerinin yüksek olduğu, ancak küçük kas gruplarını içeren biceps curl ve triceps extension egzersizlerinin 1TM testlerinde iki ölçüm arasında anlamlı fark olduğu bulunmuştur. Dolayısıyla bu çalışmada antrenman seviyesi düşük bireylerde 1TM testinin güvenirliğinin sağlanması için en az iki testin yapılması tavsiye edilmektedir.

Reliability of 1RM, 5RM and 10RM Tests in Upper Body Resistance Exercises

Öz

Research designs that examine the effect of training or similar intervention in sports sciences are widely used. In such designs, the reliability of the data obtained from the pre-test or post-test is very important. The aim of this study is to examine the reliability of 1RM (1 repeat maximum), 5RM and 10RM tests in upper body exercises (bench press, shoulder press, biceps curl and triceps extension). 23 male who have low (1 year or less) training experience participated in this study voluntarily. After one familiarization training, 1RM, 5RM and 10RM tests for four different exercises were applied two times in two-three days intervals. Differences between two measurements and test-retest reliability were analyzed. According to the results, in total 12 tests, the significant difference was found between first test and second test in two tests (BC 1RM and TE 1RM), whereas there was no significant difference between the measurements in the other 10 tests. To determine the reliability of the tests and compare with other studies, Intra-class correlation coefficient (ICC): 0.945-0.993; coefficient of variation (CV): 1.25-3.33%; typical error of measurements (TEM): 0.84-2.25; smallest worthwhile change (SWC): 0.97-2.25; Pearson correlation coefficient (r): 0.919-0.988; Effect size (ES): 0.01-0.34 were calculated. As a result, 1RM, 5RM and 10RM tests were found to have high reliability, but it was found that there was the significant difference between 1RM test-retest in biceps curl and triceps extension exercises involving small muscle groups. Therefore, in this study, it has been recommended to perform at least two tests to ensure the reliability of the 1RM test in individuals who have low training levels
