ÖZET
Amac: Bu calışmanın amacı, genc erkeklerde 1 tekrarlı maksimal (1TM) bench press kuvvetinin kestirilmesinde kullanılan formullerin gecerliliğini belirlemektir. Gerec ve Yontemler: Yirmi yedi (yaş=22,7}2,6 yıl) genc erkeğin 1TM bench press kuvveti belirlenmiştir. Kırk sekiz saat dinlenmenin ardından, katılımcıların 1TM bench press kuvvetinin %75-90'ına karşılık gelen ağırlıklar kullanılarak yorgunluğa ulaştıkları tekrar sayıları (YTS) belirlenmiştir. Katılımcıların 1TM bench press kuvveti tekrarlı kaldırdıkları ağırlık değerleri (1TM %75-90) ve YTS kullanılarak 11'i doğrusal, 5'i ustel kestirim yapan 16 formulden kestirilmiştir. Kestirim formullerinin gecerliliği icin tekrarlı olcumlerde ANOVA ve Lin'in uyumluluk korelasyon katsayısı (ρc) kullanılmıştır. Bulgular:On altı formulden 10'undan kestirilen 1TM bench press kuvveti ve olculen 1TM arasında anlamlı fark saptanmamıştır. Olculen 1TM kuvvete benzer kestirim yapan tum formuller icin uyumluluk korelasyon katsayısı ρc ≥ 0,962 'yuksek' bulunmuştur. 1TM kuvveti anlamlı derecede duşuk ya da yuksek kestiren formuller icin uyumluluk korelasyon katsayısı ρc 'zayıf' ve 'orta' duzeydedir. Sonuc: Bu calışmanın bulguları, genc erkeklerde literaturde mevcut secilmiş 16 formulden 10'unun 1TM kuvvetinin doğru ve gecerli bir şekilde değerlendirilmesinde kullanılabileceğini gostermiştir.

ABSTRACT
Objective: The aim of this study was to determine the validity of the formulas used to estimate 1 repetition maximum (1RM) strength on bench press in young men. Material and Methods: 1RM strength of 27 young men (22.7}2.6 years) was determined in bench press. Following 48 hours rest, participants performed bench press repetitions to failure (RTF) at a load of 75-90% 1RM. Their 1RM bench press strength was estimated through 16 estimation formulas (11 linear and 5 exponential), by using a load of 75-90% of 1RM and RTF. Validity of the estimation formulas was assessed using repeated measures ANOVA and Lin's the concordance correlation coefficient (ρc). Results revealed that actual 1RM bench press strength and estimated 1RM strength from 10 formulas out of 16 showed no significant difference. Results: Concordance correlation coefficient was found 'high' between estimated 1RM strength from 10 formulas and actual 1RM strength (ρc≥0.962). Concordance correlation coefficient ρc was 'low' and 'moderate' for formulas estimated 1RM 'higher' and 'lower'. Conclusion: The results of this study showed that 10 of the 16 formulas available in literature can be used accurately and valid determination of 1RM strength in bench press in young men.
