Brake, plant and leave a pre-planned 45-degree cut under control
Change of direction combines approach speed, braking, foot placement and re-acceleration around a known course. This lesson teaches a pre-planned 45-degree cut: enter inside a fixed speed band, lower before the marker, place the outside foot close enough to the body for control, align knee and foot toward the new path, push away and accelerate through the exit gate. The provider controls angle, speed, repetitions, rest and progression; reactive agility is tested separately.
1 · Permission and limits
Know exactly what you may do
2 · Get ready
Gather what you need and check the starting conditions
What you need
- Level court or field with approach, cut and exit gates
- 45-degree floor or cone guide
- Electronic timing and entry-speed measurement
- Video view of plant foot, knee and trunk
- A change-of-direction sheet for course dimensions, side, surface, footwear, entry-speed band, plant frame, exit gate, total time, COD deficit and invalid-trial reason.
Before you start
- Walk the course in both travel directions and check that no cone creates a trip point.
- Declare the approach side, plant foot, turn angle, entry-speed band and exit line.
- Report knee, ankle, hip or back symptoms and any history of giving way during cutting.
- Walk the exact approach, plant and exit line from both sides. The learner must be able to trace the route and point their eyes to the exit without turning back before speed is added.
- Walk the exact course, then rehearse lowering before the marker and looking through the exit line at submaximal speed before timing starts.
3 · The method
Follow these steps in order
- Learn the course
Walk through the exact approach, 45-degree marker and exit gate until the new travel line is unambiguous.
Why: A course error is not a movement-capacity result.
Check: The learner traces the correct line without looking back.
- Enter at the assigned speed
Build smoothly and cross the entry gate inside the provider's speed band; do not brake early to make the cut easier.
Why: Approach speed changes cutting demand; this preserves the change of direction rule for 'Enter at the assigned speed'.
Check: The timing record confirms an in-band approach.
- Lower before the marker
Use one or more shorter braking steps and lower the hips before the final plant.
Why: Late braking forces the plant to absorb too much demand.
Check: Video shows centre of mass lowering before foot placement.
- Place the outside foot for control
Plant the outside foot close enough to the body to support the turn, with the foot and knee directed toward the intended exit path.
Why: A far reaching or misaligned plant can cause braking and collapse.
Check: Knee tracks over the foot and the trunk stays controlled.
- Push into the new line
Drive away from the planted leg and direct hips, chest and first exit step along the 45-degree path.
Why: Rotation without translation wastes the redirection.
Check: The first two exit contacts follow the marked lane.
- Accelerate through the exit
Run past the exit gate before slowing; do not cut the corner or lunge at the timer.
Why: A full exit is part of the timed task.
Check: The learner stays inside the exit lane and runs through.
- Separate COD from sprint speed
Record course time and subtract or compare the matched straight-sprint time using the predeclared COD-deficit method. Keep technical validity separate.
Why: Total course time includes straight-speed ability.
Check: The record includes both total time and COD deficit.
4 · Worked example
See the whole method used once
Scenario
A coach uses a 5 m approach, one pre-planned right-side 45-degree cut and a 5 m exit, with a 3.5–3.8 m/s entry band.
Walkthrough
- The learner walks the course and rehearses the outside-foot plant at half speed.
- Trial one is invalid because entry speed is 3.2 m/s.
- Trial two enters at 3.6 m/s, takes 2.42 s and shows a stable plant and full exit.
- Trial three takes 2.39 s but the learner cuts inside the cone, so it is invalid.
- A matched straight 10 m time is recorded separately and the provider calculates the declared COD deficit.
Result
The valid cut time is 2.42 s at an in-band approach, with the COD deficit reported beside it. This is pre-planned 45-degree COD, not reactive agility.
5 · Right and wrong
Compare correct or safer execution with the common wrong version
| Moment | Right / safer | Wrong / riskier | Why it matters |
|---|---|---|---|
| Approach: Change of direction checkpoint | Maintain the measured speed until the braking phase. | Slow early outside the measured zone. | The cut becomes easier and incomparable. |
| Plant: Change of direction checkpoint | Place the foot near enough for knee-foot alignment. | Reach far outside and let the knee collapse inward. | The plant becomes an uncontrolled brake. |
| Exit: Change of direction checkpoint | Direct hips and first steps down the new lane. | Spin in place and then restart. | Rotation alone is not efficient redirection. |
| Course: Change of direction checkpoint | Run around the declared marker and through the gate. | Cut inside the cone to save distance. | The timed course is shortened. That changes pre-planned COD completion time and COD deficit at a fixed approach speed, with technique validity. It is no longer the same test. |
| Claim: Change of direction checkpoint | Call the result pre-planned COD. It is correct when the first two exit contacts follow the marked lane. | Call it reactive agility against an opponent. | Decision time was not tested. That changes pre-planned COD completion time and COD deficit at a fixed approach speed, with technique validity. It is no longer the same test. |
6 · Common mistakes
Spot the error and apply the correction
| Mistake | Fix |
|---|---|
| Entry speed is missing during 'Learn the course' in change of direction. | Measure it or use a provider-controlled approach that stays inside a declared band. |
| The learner watches the feet and loses the exit line. | Use a visible exit target and rehearse at slower speed. |
| The plant is too far from the body. | Reduce approach speed and practise a closer controlled plant. |
| A cone cut is still timed as valid. | Mark route violations before reviewing times. |
| Total time is treated as pure COD ability. | Report a matched straight-sprint time and the predeclared COD deficit. |
7 · Practice
Turn the steps into a usable skill
First session
- Walk and memorise the exact course.
- Rehearse braking, plant and exit at low speed on each provider-approved side.
- Complete progressive in-band approaches without timing pressure.
- Complete two or three timed cuts with full rest.
- Review one plant video, total time, entry speed and COD deficit.
Repeat plan
The provider controls angles, sides, approach speed, trials, rest and later reactive cues. Progress angle or speed one at a time; unplanned agility remains a separate advanced assessment.
Progress when
- Entry speed, course and plant side are repeatable.
- The plant stays aligned and the exit follows the marked lane.
- Total time and COD deficit improve without route or technique violations.
Do not progress when
- Faster time comes from slower entry, cutting the cone or a new surface.
- Knee collapse, slipping, pain, giving way or poor braking appears.
- The learner cannot keep the pre-planned course before adding a decision cue.
8 · Check the result
Measure what changed
Pre-planned COD completion time and COD deficit at a fixed approach speed, with technique validity
How: Use the same course, entry-speed band, surface, footwear and timing; record route faults, plant alignment and a matched straight sprint.
Good result: At least two in-band valid cuts are repeatable and time/deficit improves without route error, alignment loss or symptoms.
This does not prove: It does not prove reactive decision ability, opponent response, injury prevention or transfer to another angle.
Self-check
- Can you state the angle, approach side and speed band?
- Did braking start before the final plant?
- Did the plant and knee point toward the exit path?
- Can you explain the difference between total time, COD deficit and reactive agility?
9 · Stop, adapt or get help
Keep the safety boundary practical
Stop and get help
- Stop for sharp pain, a pop, joint giving way, slip, fall or inability to brake before the plant.
- End the session when route errors, entry-speed drift or knee/trunk control worsens.
- Close the course after a new twist, stumble with injury, joint giving-way or inability to decelerate under control; reassess health and entry-speed suitability before another cut.
Accessibility and adaptations
- Use a provider-selected wheeled, walking or supported redirection task with its own course and timing when running is not appropriate.
- Use high-contrast/tactile course markers and an accessible start signal without narrowing the safe lane.
- Provide the COD course as a walk-through, overhead diagram or sequential cone call, and write down any navigation aid so repeat timing uses the same support.
10 · Evidence and limits
Why these instructions are here
- primary research
Straight sprint and agility training show task-specific transfer, so pre-planned COD and linear speed should be measured separately.
Specificity of sprint and agility training methods - primary research
Resisted sprint training effects on sprint, jump and balance do not establish pre-planned or reactive COD across tasks.

Limits
- A 45-degree cut does not establish 90- or 180-degree turning ability.
- Pre-planned COD is not reactive agility.
- No cutting technique guarantees protection from knee or ankle injury.
