Leg Press

Leg Press measures leg strength

"Lower-body maximal isometric force using a modified Hammer Strength™ leg press: The seat of the leg press device was adjusted for each subject so as to create a knee angle of 120°. The subjects folded their arms across their chest and maintained this position throughout the exercise test. The subjects warmed up by pressing against the footplate twice at 50 and 75% of perceived maximum effort. After this warm-up, the subjects pressed against the footplate as hard and as quickly as possible for a 3- to 5-second duration, interspaced with 60 seconds of rest. The best attempt of the 3 presses was recorded and used in the data analysis.[...] basic procedures were as follows: Kinetic data were acquired using a tension and compression load cell (Transducer Techniques), and data were sampled at 1,000 Hz and channeled though a 12-bit analog-to-digital converter (DAS1200Jr; Measurement Computing). Force data were smoothed using a digital low-pass filter (cutoff frequency 30 Hz) and analyzed for peak force using Datapac 5 (Mission Viejo, CA, USA)."
