Force and Power ?
As far as I understand, if I was to accelerate a weight to 80% only, and then no matter the speed of the lift, the average force {strength} will always be the same.
If your RM is 200 pounds, but using 80% = 160 pounds, and your accelerating with the greatest force/speed/strength for 80% of the rep, that is roughly 200 pounds of force being used. Say the rep speed is .5/.5.
However, not average force, as then the force goes nearly down to zero for the last 20% so take off 20% off 200 = 160 pounds.
In addition, if you use a slow concentric at say 2 seconds, full rep is 2/4, you constantly only punching for the whole ROM, thus you too use 160 pounds of average force.
Question 1,
However, I will be able to move this 160 pounds 5 more times in the same time frame as the 2/4 rep, also 5 more times the distance in the same time frame.
So have not in some way used my average force {strength} 5 times ? And used more power {work energy} ?
As if you shot a putt at .5 of a second to 2 seconds, it is going to go further, thus using more force {strength} power {work energy} ?
Question 2,
Fast lifting,
Weight lifting (free weight, nautilus or universal-type), power lifting or bodybuilding, vigorous effort.
In 1 minute, you burn 10 energy {calories}
Slow lifting,
Weight lifting (free, nautilus or universal-type), light or moderate effort, light workout, general
In 1 minute, you burn 5 energy {calories}
Thus, whatever activity you do in life, the faster you do it in the same time frame, the more energy {calories you burn doing it fast.
New video proving my point.
