How Do You Time a Curved Sprint in Football?

Place timing points at the two ends of the penalty arc and time the player as they follow the curve. The published football protocol used an approximately 17 m curved path and a standing start 1 m before the first gate. Reverse the direction for the second set and keep separate results for both sides. Fílter and colleagues’ published protocol.

Where should you put the timing sensors?

• Mark the path along the arc. Use the points where the arc meets the penalty-area line. Measure along the curve if the markings are unclear. The straight distance between the two endpoints is shorter.

• Align detection with the player’s route. Put one detection point at each end and, if useful, add a split at 8.5 m along the arc. Use a practice run in each direction to confirm that the timer records crossings in the correct order.

• Mirror the starting mark. Measure the same 1 m approach before the first gate for each direction when using the published layout. Label each direction consistently and allow a clear run-out.

A and B mark the ends of the approximately 17 m timed path. Put the standing-start mark 1 m before the first timing point for each direction.

How should a coach compare the results?

Example using the same scoring rule at both sessions. Direction A → B improves from 2.85 s to 2.78 s, a change of 0.07 s. B → A improves from 2.96 s to 2.92 s, a change of 0.04 s. Keep the raw attempts and check whether the pattern repeats before changing the training plan.

How can Motion Trials help?

Gate-based sprint timers record the time between detection points, so a coach can compare runs over the same curve. Motion Trials Sprint uses wireless ground-standing sensors without tripods or athlete tags. This reduces the equipment to move when switching directions. Test each orientation in the app before recording the squad. Motion Trials Sprint specifications.

Questions coaches ask

Can a straight 17 m sprint replace the curved test?

Use the straight time as a separate baseline. The original study found that straight and curved performance shared only part of their variation. Curved and linear sprint comparison.

Should I average the two directions?

Keep both direction scores in the report. An average can summarise the session, while separate results show where the player changed. Use the same recording rules at retest. Team sprint report template.
