Examples of accommodating resistance exercise equipment

Does the equipment in this type of gym provide true weight loss exercise, or is it just another fad?

To completely understand fitness and exercise equipment it's important to comprehend the four different technologies of that equipment: 1) Constant Resistance Devices 2) Variable Resistance Devices 3) Static Resistance Devices 4) Accommodating Resistance Devices Constant Resistance Devices: "The term constant resistance means that a weight (resistance) does not increase or decrease during the course of exercise" (source: International Sports Sciences Association; 2001).

Secondly, this method does not account for reduced effort that comes with fatigue.

When following a weight lifting routine with constant resistance devices, the user experiences changes in leverage during the joint movement.

For example, when doing dumbbell curls the amount of muscular force required is much greater at the bottom of the movement (when the dumbbells are at waist level) than it is at the top of the movement (when the dumbbells are near the chin).

As the dumbbells approach the top of the movement, leverage improves and the user doesn't have to work as hard.

Unfortunately, scientists eventually proved what many weight watchers had already learned: isometrically contracting a muscle results in that muscle only gaining strength in that position.

First of all, constant resistance weight lifting exercise does not correct for changes in the musculoskeletal leverage that occurs during an exercise movement.Today, very few people consider using static resistance devices as part of their weight loss system for the simple reason that isometric exercise is the least effective of the four training technologies.Accommodating Resistance Devices: "Like variable resistance devices, accommodating resistance machinery is designed to allow you to exert maximum resistance throughout the full range of movement in each of your exercises.Some exercise equipment manufacturers have experimented with pulleys that aren't round or don't have the hole in the exact middle of the pulley, resulting in different levels of resistance felt during different points in the exercise movement.Unlike constant resistance devices, variable resistance fitness equipment does not match the natural way the human body works.

    However, a number of things can easily go wrong during this stage of the process and the labs that calculate radiocarbon dates are subject to constant scrutiny to ensure that they are up to par; but even so, samples sent to different labs often produce slightly various results. These are established by a variety of elements, including but not limited to: the quality of the sample, the quality of the lab, and the age of the sample.
