Exercise Science Center

One of our local talented artists Elaine Erickson (Fister) from Fircrest, that trains at the Exercise Science Center, recently gave me this work of art. Many of her fine works are displayed at Redeemer Lutheran Church.

Comparison of two identical Medigraphics Pulmonary Function systems to a Collins 13.5 liter Water-sealed Spirometer. Old school wins hands down with no drift between trials.

Data from the Cybex Leg Extension machine. The weight is on the left axis, and degrees (range of motion) are on the bottom axis. The setting for the ankle pad, (shorter lifters setting 1, larger lifters setting 2) are color coded on the right, A shorter lifter, (setting 1), would be doing nearly 30% more weight: i.e. 63 vs 47 lbs at mid range, even though the weight stack would show the same number of plates. Hence the name varable resistance machine.
