Tennis-Specific Endurance Test (Hit and Turn Tennis Test): Guide

Tennis is a sport of intermittent efforts: short sprints, constant changes of direction, and shots, repeated for hours. The Hit and Turn Tennis Test (HTTT) was specifically designed to reproduce that demand, combining lateral movements with actual ball striking — something a generic running test can't capture.

What does this test measure?

The HTTT measures tennis-specific endurance capacity: it combines fast lateral movements toward cones placed on either side of the court with real ball strikes, in an incremental protocol taken to exhaustion or until a predetermined maximum heart rate is reached.

Equipment needed

• Tennis court
• Basket of balls and a feeder (coach or ball machine)
• Cones to mark the lateral striking positions
• Heart rate monitor
• Metronome or audio signal to set the incremental pace

Execution protocol

1. 15-minute sport-specific warm-up (mobility, movement patterns, warm-up shots)
2. The player positions in the center of the court, behind the baseline
3. On a signal, they move to a side cone, strike a ball (fed by the feeder), and return to the center, repeating toward the opposite side
4. The pace of movements/shots increases incrementally each minute (following a predefined timing table, similar to a progressive shuttle-run-type test but adapted for tennis)
5. The test ends when the player can no longer keep up with the set pace (two consecutive misses) or reaches a heart rate close to maximum
6. Record the level/stage reached and the final heart rate

Common mistakes

• Not standardizing the speed/height of balls fed by the feeder (affects the actual difficulty of each shot)
• Not accurately marking the lateral distances from the center to the cones
• Letting the player "cut corners" by shortening distances
• Not recording the final heart rate, which is key for comparing relative effort between tests

How to interpret the result

Indicator	Interpretation
Higher level/stage reached than in a previous test	Improvement in tennis-specific endurance
Similar final heart rate but higher stage reached	Real improvement in physical capacity (same relative effort, more output)
Similar stage but lower final heart rate	Improvement in efficiency/economy of the specific movement

There aren't widely established normative tables for the HTTT (unlike other tests), so its main value lies in individual longitudinal tracking: comparing the stage reached and heart rate each time the test is repeated throughout the season.

Relationship to other tests

The HTTT pairs well with:

• T-test (agility test) — assesses the lateral movement component in isolation, without the striking component
• Repeated sprint ability (RSA) test — measures anaerobic capacity to repeat short efforts, relevant during long rallies or tie-breaks

If a player has a good T-test result but underperforms on the HTTT, it may indicate that the limiting factor isn't pure movement, but the combination of movement + striking + decision-making.

Track progress with Movalytics

The HTTT requires recording several pieces of data at once (stage reached, final heart rate, date) for it to be useful as a tracking tool. With Movalytics you can save each test repetition with all its data, and compare your players' progress throughout the season, identifying whether improvements come from general fitness or from the efficiency of the specific movement pattern.

Frequently asked questions

Do I need a professional feeder to run this test? It's not essential, but you do need someone (a coach) or a ball machine that can maintain a reasonably consistent feed in speed and direction so the test is reproducible. From what playing level does this test make sense? It's most useful for intermediate-to-advanced players who already have solid stroke technique, so the limiting factor is physical rather than technical. How often is it recommended to repeat it? Every 8-10 weeks, or at the end of each preseason/season block, avoiding weeks close to important tournaments.
