Hi all,
Without sophisticated equipment, {I have an EMG} when lifting weight up and down, as in weightlifting/bodybuilding, would there be any way to tell when/if the weight starts to decelerate ?
I have a Smith Machine, this is a machine, that the weight goes up and down on two rods, on bearings, see below.
With this machine, I am able to lift if I want open handed, {to which I down, and your lifts suffer} if wanted, if I lowed then lifted 50% of my 1RM, {Repetition Maximum} as explosively as I could, open handed, the weight at the end of the lift will move slightly out of my hands, {say the positive was 20in and the negative was 20in} this mean in my opinion that there was no deceleration when in contact with my hands, is this correct please ?
If I then lift 80% of my 1RM, in the exact same manner as above, but the weight because it was heaver did not leave my hands, {If you do the equations for a machine lifting 80% at 2ms, the weight would leave your hands for about 4in, but because of the biomechanical disadvantages and advantages, this does not happen with the muscles of the body} but still, does that not mean there is not deceleration on my behalf ? As I am trying to push the weight as explosively as I can, then after I push up explosively as I can, I then lower again. Next and more to the real, would there be a deceleration {I know there must be a deceleration, if I push up and then lower the weight} on my behalf ? Meaning if I push up as explosively as I can, 80% for 20in that will take say .3 of a second, will I use less force than the weight ? As if we go back and look at me pressing up 50% I would press up as hard as I can, thus the weight would move out of my hands, then, and only then would it start to decelerate, thus no deceleration on my behalf, then when it dropped into my hand I would then lower it, and repeat the lift.
The only problem here, I that I want to find if there is deceleration on my behalf lifting 80% closed handed ? As is not my weightlifting/bodybuilding lifting up and down, just like if I lifted 80% 20in, and then there was a steel plate to which I hit, then, I would think not deceleration on my behalf {Mind you I do not lift to a steel plate, thus, it’s basically the same} then lower.
