HOW TO DO IT
Transitions: extension; flexion/retraction; cross-over/cross-under terminology
This page applies the carving application framework to Transitions: extension; flexion/retraction; cross-over/cross-under terminology. Treat the listed dimensions separately rather than assigning one universal cue to the whole topic. Carving organizes an edge-supported path with little lateral skid. Edge angle, inclination, angulation, pressure and trajectory must be interpreted through the board's actual response.
Preparation and setting
Use the setting and competence boundary below. This is a page-level learning/application text; use the exact linked movement for reproduction instructions.
Execution / application sequence
- State the page-specific task and the conditions in which it is being attempted.
- Separate extension, flexion/retraction, cross-over/cross-under terminology as individual observations.
- Choose a wide clear suitable piste.
- Start with established rounded linked turns.
- Identify the phase to change using the matching Package1 card.
- Increase demand modestly while preserving speed management and space.
- Observe the track and exit.
- Return to the simpler turn if grip or line fails.
Learning and practice
Compare tracks and the earliest loss of organization. Use the named style's mechanics rather than trying to touch snow as the goal.
Errors, limits and corrections
More edge angle cannot compensate for poor line, unsuitable grip or a clearance problem.
Observable checks
The page-specific task, conditions, known components and missing procedure can be explained. Successful application is checked in the actual task, not inferred from reading.
HOW TO DO IT
Cross-Over, Cross-Under and Cross-Through: Attributed Transition Models
These labels describe relationships between board and body paths, and different sources attach different movement expectations to them. They must not become automatic aliases for tall, low or retraction. In the BeckmannAG hardboot model, cross-over emphasises body movement across the board, dynamic cross-under uses leg extension/retraction to shape the path, and cross-through blends elements of both. The detailed source-specific wording is retained in CM10–CM12. This article teaches recognition and a grounded comparison of already established strategies. It is not a standalone reconstruction of that author's entire hardboot progression or a laid-turn tutorial. Basic description is better than forcing a turn into a category: “legs shorten at connection; body moves across; board stays in contact” remains useful when terminology is disputed.
Preparation and setting
Required for sliding comparison: reliable ordinary pairs and established grounded versions of CTRC-16/17. Helpful: an observer and familiar suitable gentle terrain. A rider still learning first carves should study the descriptions and defer the comparison. Do not add contact, rebound hops or hardboot posture to an unfamiliar softboot task.
Learn and reproduce it
- Select the source and state its terminology explicitly. Name what it means by the label before discussing whether the rider demonstrates it.
- Observe a normal pair. Describe body travel, board travel, leg-length change and contact before assigning a term.
- Repeat the established extension-based pair at a controlled demand. Record the actual relationship at transition; do not assume the taller moment proves cross-over.
- Separately repeat the established flexion/retraction-based pair. Record what moves underneath, across and closer together.
- Compare outcomes: connection continuity, path, speed, range and exit. Keep shape and terrain comparable.
- Discuss how a blended description could apply when both paths contribute. Do not attempt a new steep/contact cross-through progression from the name alone.
- Store the observation with its source model and unresolved terminology differences. A definition from one author cannot settle every association's vocabulary.
Exercises and diagnostic errors
CD18 is the observation/comparison protocol. CD16/CD17 supply the established grounded strategies; CD03 checks performance rather than naming.
Success and next use
The rider/coach can distinguish observable movement from source-specific naming and compare established strategies without losing control. The three existing terminology cards can receive this attributed explanation; global equivalence remains unresolved.
Diagnostic hypotheses and rechecks
Possible causes are hypotheses to test, not diagnoses inferred from one attempt.
| Observation | Possible cause | Diagnostic exercise | Correction | Recheck |
|---|---|---|---|---|
| Every low transition labelled cross-under | Posture treated as complete path description | CD18 board/body/leg observation | Describe movement before assigning the attributed label | Record contains actual events and source model |
| Cross-through merged with retraction in database | Terms assumed universally equivalent | CD18 terminology/source check | Keep related_to until model-specific equivalence is demonstrated | No unqualified same_as relation |
| Rider attempts advanced contact sequence from a term | Reference article mistaken for a complete lesson | CD18 readiness gate | Retain the established grounded task; defer new style progression | Comparison stays within learned controls |
Methodology connection
CM10–CM12 are original-author hardboot accounts newly reviewed here. CM05/CM06 use different height-oriented names. The observation protocol is editorial; no claim of a universal certification definition is made.
