The legs, arms, and trunk start with no motion, accelerate, and then decelerate.
Thus, accentuation trains only in the strongest position, not the weakest.
One of the disadvantages of this type of equipment is that it does not correct for differences if biomechanical leverage changes.
The Force-Velocity Curve Before going into what the chains and bands do, I first have to set the groundwork and explain what the force-velocity curve is.
As you see below, when force (weight lifted) increases, velocity (bar speed) decreases.
The effectiveness of a strength exercise depends on its velocity. Explosive strength is “the steepest increase in strength in the shortest possible time.” Jumping, bounding, plyometrics, and isokinetics are explosive.
Olympic weightlifting is not; it is a speed-strength sport that does not build explosive power.
NIFS has recently updated the weight room, including seven new half racks.
