One repetition maximum (1RM) for leg press is used to be a clinical reference for resistance training of lower extremities. However, the Western standard was built on “bilateral”leg press test from “full”hip and knee joint flexion to extension regardless of race and clinical application. Subjects and Methods. Two hundred and twenty healthy sedentary volunteers(105 males and 115 females) aged 20-80 years old and 17< BMI< 31 performed as many repetitions of unilateral leg press from 90°knee flexion to extension as possible. Results. 1RM strength for leg press was correlated with body weight, age and gender (p<.05 ). The regression equation was: unilateral 1RM= 8.6+ 1.0 x BW (kg)- 8.3 x Age (1-3, representing 20-39, 40-59, 60-80 y/o, respectively) + 10.2 x Gender (female=1, male=2), R2=0.74 .Discussion and Conclusion. The ability to perform leg press increases with weight, decreases with increasing age, and females do not perform as well as males. The present study provides a more realistically reference for clinical applications.application/pdf168016 bytesapplication/pdfzh-TW國立臺灣大學醫學院物理治療學系暨研究所One repetition maximumleg presslower extremity strengthjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/25645/1/932213E002076.pdf
