Accommodating resistance machines
Hi everybody, it has been a long time since I posted and I wanted to put up something fitness related.
This is an essay I wrote about the four types of resistance machines/technology that is out there.
It may not be interesting to some of you, but those of you who are into exercise science and fitness gadgets and gizmos, may find some interesting ideas and perspectives. The four technologies of training equipment are constant resistance devices, variable resistance devices, accommodating resistance devices, and static resistance devices.

Constant resistance devices are things like free weights or pulley machines where the wheel is round so it gives even resistance.
One of the disadvantages of this type of equipment is that it does not correct for differences if biomechanical leverage changes.
Such as, in a squat with a barbell, the weight of the bar stays the same throughout the lift.
However, the squat will be much harder at the bottom due to reduced leverage and much easier at the top of the motion.
So at the top of the squat, we are losing some of the benefit of the exercise.
This is also an advantage, as it has been shown that this is how our muscles evolved to work and is a natural type of stress to the body that helps us develop better stabilization strength, and power as well (Hatfield, p. For general population training this will improve a client’s joint integrity through training the stabilizer muscles and also teach them how to move objects in real life better than machines.Also for everyday people, this type of resistance training has a disadvantage.For deconditioned people or first time exercisers this may be dangerous even with light loads.They may have old injuries or just be so inflexible and immobile that the leverage disadvantage becomes too much when trying certain exercises with a full range of motion.They also may not have the core or stabilizer strength to do the exercise safely.In these cases, machine exercises may be a better option to start training.Tags: Adult Dating, affair dating, sex dating
