505 Change-of-Direction Test: Timing Setup and Scoring

In the standard 505 test, the athlete runs 10 m to the timing line, continues 5 m to the turn line, makes a 180-degree turn and sprints back through the same timing line. The timed section covers 5 m into the turn and 5 m back out.

Mark the approach, timing line and turn line

Mark the start, then measure 10 m to the timing line. Place the turn line a further 5 m down the lane. Use equipment that can start on the first crossing and stop on the return crossing. Confirm the setup for your device with a practice attempt. Some systems require a dedicated shuttle or change-of-direction mode.

Layout: Start → 10 m approach → timing line → 5 m → turn line → 5 m back through timing line.

Use the same rules for both turning feet

Tell the athlete which foot to plant. Follow your protocol’s rule for contacting or crossing the line, and have a coach observe the turn. Give time to recover between maximal runs. Record each side separately. If the athlete turns early, slips or uses the other foot, mark the attempt invalid and repeat it after recovery.

Decide whether you will report the fastest or mean valid time per side. Keep the approach length, surface, footwear, turn instruction and scoring rule consistent. Research protocols vary, so note the exact version you used. Example 505 research protocol

Interpret a planned turn in context

The 505 combines approach speed, braking, the turn and acceleration back out. An athlete can produce a good total time with different movement strategies. Pair the score with video if you need to understand what changed. The direction is known in advance, so use a separate test if you want to assess reacting to a cue or opponent.

For a straight-line comparison, use the 20 m sprint test protocol.
