Sprint Performance & Change of Direction (COD) - Coggle Diagram
Sprint Performance & Change of Direction (COD)
Linear Acceleration
Builds speed from a start or after a cut
Forward body lean helps direct the push backward
Forward net impulse increases forward momentum
RFD and coordinated steps help build speed
Maximal Velocity Sprinting
Maintains top speed with quick, coordinated steps
Upright posture and vertical force help support the body
SSC and tendon stiffness support quick rebound during short ground contacts
Stride rate × stride length determines running speed
Change of Direction / Agility
COD: the direction change is planned ahead
Agility: react to a cue, like an opponent moving
Deceleration reduces speed before the cut
Stability and foot placement help control the turn
Reacceleration builds speed in the new direction
Perception guides when and where to cut in agility
Perceptual-Cognitive Decision Making
Visual scanning spots space and other players
Anticipation helps predict the next move
Pattern recognition picks up familiar cues
Situational knowledge uses past experience
Reaction time affects how quickly the response starts
initiates → the decision to maintain or change momentum
guides → when and where to move in reactive agility
Decision to maintain or change momentum
Maintain: keep the same speed and direction
Change: speed up, slow down, or turn
guides → execution of the chosen movement
Execution: putting the decision into action
Rate of Force Development (RFD): how quickly force builds
Neural drive helps muscles build force quickly
Stretch-shortening cycle (SSC): quick stretch then shortening helps push-off
helps → quick rebound at maximal velocity
Muscle/tendon stiffness helps transfer force
Short ground contacts leave less time to produce force
supports → rapid force production during acceleration
Biomechanics / Technique
Body positioning helps direct force
Stride adjustment changes step length and timing
Neuromuscular coordination keeps movement in sync
Arm action and knee drive help coordinate the stride
Foot orientation, placement, and contact affect braking and push-off
Impulse changes momentum
Force-time relationship: impulse = average net force × time
Ground reaction force is the ground pushing back on us
Force direction affects whether we speed up, slow down, or turn
Eccentric strength helps control braking
Isometric and core strength help stabilize the body
Concentric and reactive strength support push-off
changes → momentum when braking and reaccelerating
supports → acceleration, top speed, and agility
