Description
MuscleLab (Ergotest Technology, Langesund, Norway) is a data collection device that connects to a computer via a USB port. Various sensors can be connected to it for data recording. MuscleLab measures the lifting velocity and calculates the average power output of a barbell during free weight strength testing. The device consists of a linear encoder that can be attached to a bar or sliding rack to track displacement and velocity. A software program uses the known mass of the bar and measured velocity to calculate average power. MuscleLab (ML) also uses power from sub-maximal lifts to estimate a one-repetition maximum lift (1-RM).
