Power




Power

Power: The rate of doing work or the product of force and velocity. So, Power = Force X speed of force application (P = F X v). It can also be described as work divided by time or P = W/t. These two equations produce the same result.

Force Velocity Relationship

Force-velocity Relationship: A propery of skeletal muscle contraction in which the force capability of a given muscle contraction is dependent on the velocity of shortening of the muscle.

Sequential and Simultaneous Lifts? What is the Difference Between Them?

Every once in a while you will hear someone calling the squat a simultaneous lift. You'll even hear people calling the deadlift a sequential lift. What does this mean, and is it correct?

Well, these terms come from the description and measurement of the coordination of human movement, a branch of biomechanics called kinematics. Movements, in this context, are looked at in terms of the movement of body segments, and this means also the action of the body's joints. You may have never given it a second thought, but during some movements the joints act "all at once" or simultaneously and in others they act one after the other in a sequence. Most movements, however, are not really so black and white and fall in a continuum between the two. Sometimes, for instance, a movement may look to be simultaneous, but upon close observation be sequential.

Speed-Strength

Speed-Strength: Speed training where there is relatively more contribution from acceleration than force. Speed-strength training uses lower intensities than power training or strength-speed training and has its greatest effect on rate of force development rather than maximum strength

Slow Versus Fast Pulls: Why is the Deadlift a Slow Pull and the Olympic Lifts Fast Pulls?

What makes a "pull" slow or fast. Is it a choice? After all we can do speed deadlifts. So does that make the deadlift a fast pull?

These questions come up because most strength trainees have been trained in the slow lifts but not the fast Olympic lifts. The information they have received about the fast lifts is from those who "dabble" in them. Alternatively they receive information from those who only dabble in strength in general…but that is another subject.
