Which of the following instructions are important to give to an athlete who is preparing to perform the T-test?

describe visual focus when running
when running:
-forward or backward: eyes are directly ahead with head in neutral position (focus on the point they are moving toward/away from)
-lateral: look ahead and use peripheral vision

a. Keeping an erect torso
b. Turning the feet outward during the stride
c. Bouncing with a vertical sway
d. Swinging the arms across the body
a. Keeping an erect torso
How do you minimize braking forces at ground contact?
by maximizing the backward velocity of the leg and foot at touchdown and by planting the foot directly beneath the center of gravity
what is the dual role of the hamstring in sprinting during the late recovery/
simultaneous concentric hip extension and eccentric knee flexion
what is the most important aspect limiting recovery of the leg as it swings forward?
eccentric knee flexor strength

1. adaptive
2. balance
3. combinatory

coordination of body movements into a given action
Describe the coordinative ability: Differentiation
accurate, economical adjustment of body movements and mechanics
Describe the coordinative ability: Orientation
spatial and temporal control of body movements
Describe the coordinative ability: Reactiveness
quick, well-directed response to stimuli
Describe the coordinative ability: Rhythm
observation and implementation of dynamic motion pattern, timing, and variation
what are maximal backward running velocities
~60-80% of forward velocities
What is high speed backpedal running characterized by?
shorter SL, greater SF, longer support time, later application of peak GRF, greater hip angular velocity, smaller ROM at knee, hip, ankle
what does GRF stand for
Ground Reaction Force
Which of the following technique errors should be avoided when backpedaling?
a. Lean the trunk backward
b. Focus the eyes straight ahead
c. Originate the arm movement at the shoulders
d. Shift the body weight primarily to the balls of the feet
a. Lean the trunk backward

a. Swing the arms through a large ROM
b. Immediately attain an upright position
c. Minimize the initial knee lift
d. Push-off with the front leg only
a. Swing the arms through a large ROM
acceleration and max velocity running are characterized by 2 phases:
1. flight=recovery and ground preparation
2. support(single leg)=eccentric braking and concentric propulsion
Which of the following components of sprinting technique will be improved by an athlete performing this exercise(sled pull)?
a. An overspeed effect
b. Speed-frequency
c. An assisted speed effect
d. Speed-strength
d. Speed-strength
this method of speed training includes gravity-resisted running (uphill/stairs) or other means of achieving an overload effect (harness/parachute). the goal is to improve explosive strength and SL
sprint resistance
this method of speed training includes gravity-assisted running (downgrade sprinting on 3-7degree slop) or high speed towing (harness and stretch cord) or other means of achieving an overspeed effect. goal is to provide assistance to improving SF (stride rate)
