chapter 17 Flashcards
speed
the skills and abilities needed to achieve high movement velocities
agility
the skills and abilites needed to explosively change movement velocities or modes
speed-endurance
the ability to maintain maximal movement velocities or repeatedly achieve maximal accelerations and velocities
special endurance
the ability to repeatedly perform maximal or near-maximal efforts in competition specific exericise:relief patterns (work:rest ratios)
2 qualities of competition specific exericise relief patterns
1: the metabolic power to executs specific techniques at the targeted effort level
2: the metabolic capacity to do so repetitively
force equation
mass x acceleration
impulse
the change in momentum resulting from a force
power
the rate of doing work the product of force and velocity
sprinting error: hands too wide
Cause: misunderstand of movement
Correction: place arms at shoulder width
sprinting error: not getting 90 degree of front leg
cause: hips too high or low
correction: adjusting hip height
sprinting error: too much weight distributed to arms
Cause: improper weight distribution
Correction: raising hips upward more than forward and straightening arms and distributing weight evenly
sprinting error: unnecessary tension in dorsal muscles
cause: misunderstanding of movement
correction: normal head alignment eyes focused on group
sprinting error: “jumped” first stride
cause: push off angle too high; upward thrust too steep
correction: increase forward lean, head alignment, accelerate leg
how can force be expressed
impulse and power (mass x acceleration)
the final movement velocity targeted when a mass is being accelerated
velocity specificity
