Isokinetic Devices Essay Example for Free
Isokinetic Devices examineThe word isokinetic is most commonly use in sports science and medicine. In these settings isokinetic defines a type of proceeding or movement. Isokinetic movement is actually the opposite of isotonic movement which is probably the easiest way to think of it. isotonic movement is the most common type of movement we human beings per exercise Isotonic movementIn almost every situation, every day, we perform isotonic movements. In these types of movements we pick up a inflexible weight, an empty pan basically anything that has weight. The weight of the pan is fixed but we decide how card-playing to change by reversal it. We can pinnacle it slow, fast, or anywhere in between. The key to this type of movement is we decide how fast it goes but the weight (resistance) remains constant. Isokinetic movementIn isokinetic movements the situation is reversed now we tell an isokinetic instrument (the dynomometer) to move only at a certain speed (normally mar kd in degrees per second). The machine pass on then vary its resistance against us to maintain that speed. This means if we push against the machine hard it try give back allot of resistance to maintain the speed it was told to go at. If we push or pull softly the machine reduces the weight to maintain the speed. To achieve isokinetic movement there are many diametrical ways of developing the resistance, however, most people use an isokinetic device. Isokinetic devices are referred to as isokinetic machines and they vary vastly in technology and price. Most medical isokinetic machines are top of the range.They use a powerful motor to get out the isokinetic resistance to the force applied and then use a computer to keep the motion smooth, provide the acceleration and to record the results. In medical systems the components (the motor, gear box and computer control) are what make the machines so very expensive but they are also the parts that make them so very good. separate iso kinetic machines use cheaper ways of developing the isokinetic motion. These methods include (but are not exclusively) hydraulic systems (water or oil commonly) deal based systems (not really used anymore due to noise and running costs), friction based systems and springy resistance machines. Advantages* Maximal loading throughout whole range of motion. * Objective, reproducible and easily quantifiable. * Muscles easily isolated. * Safest form of exercise. * Few contraindications. Disadvantages * Time consuming. * Requires a lot of training and skill to use. * Costly. * Results can be difficult to analyze between machines.Other types of isokinetic / s The most common isokinetic device used every day is a lift. Here no matter how many or few people get in the lift (which varies the resistance) the lift moves at a constant speed. Isokinetic is also be used in gas digest Isokinetic still means constant velocity or speed of motion but is used to describe the velocity of gas entering a sampler being the same as in a chimney or flue. Many isokinetic gas samplers work automatically. Two main types of equipment are produced Automatic samplers used for dust and aerosol monitoring.
