Hydraulic Exercise Equipment

Hydraulic Exercise Equipment is form of exercise machine used in a number of strength training programs. They are most often found in circuit training gyms.

Hydraulic circuit training machines were first developed for The Henley Corporation in the 70's, [ [http://www.shapesforwomen.com/hydraulicfitness.asp Shapes for Women] ] and are now becoming an increasingly popular form of exercise.

The fundamental principles behind these designs are based on fluid dynamics: Force that is applied at one point is transmitted to another point using an incompressible fluid known as hydraulic oil. [ [http://science.howstuffworks.com/hydraulic1.htm How Stuff Works Science edition] ]

For circuit training applications, each piece of equipment is specifically designed for a given exercise. The effort is applied through the range of motion of the exercise acts on a lever against a piston which moves linearly within a hydraulic cylinder. The cylinder is filled with hydraulic oil which is displaced by the motion of the piston, and is allowed to flow to the opposite side of the piston through an adjustable orifice.

Resistance to the motion is determined by the amount of effort applied and the adjusment size of the orifice. This is a key feature of this design and allows the resistance to be adjusted to an individual's strength level. [ [http://www.healthfxamerica.com/healthmaxpro/guide/index.html Healthax Pro] ]

Hydraulic exercise machines were first developed by Hydra Fitnes in the 70's, [1] which later was purchased by Henley Healthcare in the 80's and put into a circuit format called PACE. This type of circuit now becoming an increasingly popular form of exercise.
