What type of ability is power?
Biomotor
What are the two aspects of mechanical power?
Torque/product of force and velocity
What is the rate of doing work?
Power
How do you calculate power in terms of torque?
(force x distance)/time or work/time
How do you calculate power in terms of force and velocity?
force x velocity or force x (distance/time)
When is muscle most efficient?
When it has optimal power outputs
What is optimal power output?
High power output over a short period of time
What is the most important contributor to power output and whole limb movement efficiency?
Intermuscular coordination
What is intermuscular coordination?
How different muscle groups work together to produce smooth and efficient movements
What increases from power training?
Muscle efficiency
What does intensity modify?
Volume
What is load synonymous with?
Volume
What is effort synonymous with?
Intensity
What is force in the context of calculating power?
The load
How is load modified?
Changing the percent of 1 RM
What is velocity in the context of calculating power?
how fast you move
What is typically neglected in power?
Velocity
What is power’s variable for work and rate?
Rep per second
What does this graph represent?
As force decreases, power increases
What is a muscular determinant that increases velocity?
An increase in fiber type training
What causes this force velocity curve to shift? And in what direction?
Increased muscle size, right
What does this force velocity power graph tell us?
An increase in muscle volume increases power/force output
A slight increase in force has a big impact on power
What are the positives of explosive ballistic training?
Increased rate of force development
What are the negatives of explosive ballistic training?
Faster force drop off
What are the negatives of heavy resistance training?
Slower rate of developement
What are positives of heavy resistance training?
More time until force fall off
As the rate of torque developement increases what decreases?
The recruitment threshold
What gets aided the most from a decrease in recruitment threshold?
High threshold motor units
What causes all motor units to be recruited?
Max effort contractions
Are all motor units recruited if there is a max effort contraction but with light weight?
Yes
What kind of relationship do force and velocity have?
Inverse
What occurs during heavy resistance training?
Small increase in velocity, large increase in force
What occurs during mixed resistance training?
Big increase in both force and velocity
What occurs during ballistic/explosive resistance training?
Big increase in velocity, small increase in force
What are some examples of functional applications of power training?
Sit to stand, walking speed, and carrying laundry basket
What is most important to functional outcomes of power training?
Mode of movement
When are cluster sets used?
Advanced strength programs
What are cluster sets?
Max effort and power for 1 rep, short rest, next rep
