T-Test for Agility: Protocol and Reference Values

The T-test is one of the most widely used agility tests in sports where lateral and backward movement happen constantly — basketball, volleyball, handball, or tennis. Its "T" shape forces the athlete to combine a forward sprint, lateral movements (shuffle steps), and backward running — three patterns that are rarely assessed together in other tests.

What does this test measure?

The T-test evaluates multidirectional agility: forward acceleration speed, the ability to move laterally while keeping the center of gravity low, and control during backward running. It's particularly representative of defensive movement patterns in court sports.

Equipment needed

• 4 cones
• Tape measure
• Stopwatch (manual or timing gates)
• Indoor court, track, or short-grass surface

Test protocol

1. Place one cone (A) as the start/finish point
2. 9.14 meters (10 yards) from A, place cone B
3. On each side of B, 4.57 meters (5 yards) away, place cones C and D, forming the "T"
4. The athlete starts at A: sprints forward to B and touches the cone with their hand
5. From B, shuffles laterally (without crossing the feet in front) to C and touches the cone
6. From C, shuffles laterally to D (passing through B) and touches the cone
7. From D, shuffles laterally back to B and touches the cone
8. From B, runs backward to A, crossing the finish line
9. Time the total run. Perform 2-3 attempts with full recovery and record the best time

Common mistakes

• Crossing the feet during the lateral shuffle (it should always be a side step/shuffle)
• Not touching the cones with the hand at each change of direction
• Turning the body during the backward run instead of maintaining a forward-facing orientation
• Comparing times across different surfaces (hardwood vs. grass changes results significantly)

How to interpret the result

Level	Time (seconds)
Excellent	< 9.5 s
Good	9.5 - 10.5 s
Average	10.6 - 11.5 s
Below average	11.6 - 12.5 s
Poor	> 12.5 s

These values are guidelines for trained team-sport athletes. Competitive basketball and volleyball players often score below 10 seconds, while in the general active population times typically range from 11 to 13 seconds.

Related tests

The T-test pairs especially well with:

• Illinois Agility Test — adds a slalom component and a longer linear run
• 5-10-5 Pro Agility Shuttle — focuses more on pure acceleration-deceleration, without lateral movement

Using the T-test alongside the 5-10-5 gives you a fairly complete picture: one measures "pure" change of direction (180°), and the other measures lateral/defensive ability.

Tracking with Movalytics

Improvements in agility are usually small (tenths of a second) but highly significant at a competitive level. With Movalytics you can log every T-test attempt, keep a history for each athlete on your team, and quickly spot who's progressing and who needs to adjust their agility training.

Frequently asked questions

Is the T-test valid for individual sports? Yes, although it's most useful in sports involving multidirectional defensive movement (basketball, volleyball, handball, tennis, padel). In purely linear running sports (track sprinting), it provides less specific information. What footwear is recommended? The same shoes the athlete would use in competition, since traction has a big impact on lateral movements and braking. How many repetitions are needed for a reliable result? 2-3 attempts with full recovery between them (2-3 minutes) is usually enough. Use the best time, not the average.
