Angular Kinetics - L25 Flashcards
how long is the drive phase for sprinters
0-10m
how long is the transition phase for sprinters.
11-35m
how long can a sprinter hold max velocity for
36-60m
how long is the maintenance phase for a sprinter
61-100m
what is QAHP
quick explosive acceleration with high peak force. world class level sprints (50-100m), jumps and throws.
what is QAMP
quick acceleration with moderate peak force. world class level middle distance (500-1000m). national level decathalon.
what is LAMP.
low acceleration with moderate peak force. above average high school athlete (400-800m)
what is LALP
low acceleration with low peak force. low average high school track and field. long disatnce, marathon.
what are we trying to get the most of in the acceleration phase?
propulsion - as to why sprinters have blocks.
to reach peak v
we need our propulsion force to be higher than resistance forces.
180m/s of ground contact in 100m sprint. what strength quality
explosive cocentric strength of muslces
100-75m/s of ground contact in 100m sprint. what strength quality
explosive muscular stiffness and elasticity.
how can sprinters cycle the limb through the recovery phase quickly in order to apply forces in the next stride?
cycle through the recovery phase fast, no point in touching down faster if you do not start with decreasing recovery time.
difference in the application of force for marathon runners and sprinters.
sprinters apply the force directly beneath them whereas marathon runners have a greater displacement.
do sprinters have greater hip ROM
yes, so they can produce more GRF
