5-0-5 Agility

Overview

The 5-0-5 agility drill is a standardized change-of-direction agility test used to assess an athlete’s ability to accelerate, decelerate, plant, pivot 180°, and re-accelerate over a 5-meter course. It is commonly used in athletic assessment, return-to-sport screening, and performance monitoring as it isolates the mechanical demands of rapid direction change.

Instructions

Set up two lines or cones 5 meters apart on a flat surface.
Place cameras 45 deg to the same side from the running line pointed at the center. Use landscape mode and ensure cameras can see the full 5-meter distance (both cones).
Stand at the start line in an athletic ready position.
On go, sprint forward toward the turn line.
Plant one foot on or just past the turn line, pivot 180°, and sprint back through the start line.
Perform with both left and right foot as the plant foot across separate trials.
Perform at maximal effort for fastest time.

Dimensions

Required inputs for processing:

None — direction of movement is detected automatically from the pelvis trajectory

Output Variables

Generic Outputs

Every capture includes session metadata, standard joint angle/velocity time series, and 3D keypoint positions common to all movements. See Generic Outputs for the full list.

Events

Metric	Description
Start	When the athlete initiates movement, detected as when pelvis velocity exceeds 0.2 m/s
Turn	The instant of maximum pelvis displacement, corresponding to the 180° pivot
End	When the athlete returns to the start position
Left Foot Strike	All left foot contact frames between Start and End
Right Foot Strike	All right foot contact frames between Start and End
Left Foot Off	All left foot off frames between Start and End
Right Foot Off	All right foot off frames between Start and End

Phases

Phase	Start	End
Approach (First Half)	Start	Turn
Return (Second Half)	Turn	End

General Metrics

Metric	Units	Description
Direction	string	Auto-detected direction of first sprint (‘right’ or ‘left’)
Total Time	seconds	Duration from Start to End
First Half Time	seconds	Duration from Start to Turn (approach/deceleration)
Second Half Time	seconds	Duration from Turn to End (re-acceleration)
Turn Time	seconds	Time between last foot contact before and first foot contact after the Turn

Ground Contact Time Metrics

Ground contact time (GCT) is reported per step for up to 5 steps per leg per half. _1_ refers to the approach (first half); _2_ refers to the return (second half). Step index follows temporal order.

Metric	Units	Description
Left GCT — Approach, steps 1–5	seconds	Left foot ground contact time during approach
Right GCT — Approach, steps 1–5	seconds	Right foot ground contact time during approach
Left GCT — Return, steps 1–5	seconds	Left foot ground contact time during return
Right GCT — Return, steps 1–5	seconds	Right foot ground contact time during return

Step Length Metrics

Step length (SL) is the distance traveled by the ankle joint center from foot strike to foot off for each step, up to 5 steps per leg per half.

Metric	Units	Description
Left SL — Approach, steps 1–5	meters	Left step length during approach
Right SL — Approach, steps 1–5	meters	Right step length during approach
Left SL — Return, steps 1–5	meters	Left step length during return
Right SL — Return, steps 1–5	meters	Right step length during return

Pelvis Path Time Series

Pelvis position, velocity, and acceleration are returned as full time-series arrays, with the coordinate frame rotated to align the X axis with the direction of movement.

Metric	Units	Description
Pelvis Position X	meters	Pelvis position along the sprint axis
Pelvis Position Y	meters	Pelvis vertical position
Pelvis Position Z	meters	Pelvis position perpendicular to sprint axis
Pelvis Velocity	m/s	Pelvis velocity along the sprint axis
Pelvis Acceleration	m/s²	Pelvis acceleration along the sprint axis

Notes

Kinematic data typically captured at 120 Hz for agility drills
Direction is detected automatically; separate trials should be performed for left and right plant foot
Step indices are assigned in temporal order; not all 5 steps per leg may be populated depending on trial length and gait
Turn time captures the period of foot contact at the change-of-direction pivot and may be sensitive to plant foot strategy
