The 1 RM is the ability of a person to lift a certain weight once.
The EN-TreeM 24 kg (Enraf Nonius) software calculates 1RM with
the aid of the 1RM protocol. Subjects were in a sitting position
and perform Scott-curl on ENTree pulley. Instruct the subject to
inhale during flexing the elbow and exhale during extending it. The
subjects are to perform a controlled, smooth and well coordinated
movement. The test was stopped as soon as the subject cannot
perform the movement well coordinated any longer. Strong verbal
encouragement was provided during the measurement. The mean
values of two measurements were used for the analysis.
