Learning Connection Model
- what are the 3 skills
- People Skills
- Technical Skills
- Teaching Skills
Pressure - along the length - definition
Control the relationship of the COM to the Base of Support to direct pressure along the length of the board
- can be done by moving the body above the board, or moving the board under the body
Pressure - along the width - definition
Control the relationship of the COM to the Base of Support to direct pressure along the width of the board
- move the pressure, without tilting the SB
Pressure - on the board - definition
Control the magnitude of pressure created through board/surface interaction-
- down unweighting movements, retractions movements, pump a roller
- look for vertical f/e to see how the rider is controlling pressure (if not present, they’re likely not!)
Pivot - definition
Control the board’s pivot through flexion/extension and rotation of the body
- lower level is mainly upper body
- higher level can do through flexing/extending
Tilt - definition
Control the board’s tilt through a combination of inclination and angulation
- angulation is flexing joints
- inclination is tipping the body without f/e
Torsional Flex (aka - twist) - definition
Control the board’s torsional flex through flexion/extension and rotation of the body
- unique to SB (not in skiing fundamentals)
- SB’er can actively twist
- if executed well, should be sequential (one, two)
SB Fundamentals
- Riders are always doing all of these
- think of dials, turning up and down
- truths
Ollie - main SB Fundamentals
1) moving pressure along the length
2) moving pressure on the board via vertical f/e
flatland 360 - main SB funds
1) pivot - upper/lower body separation (rotary movements)
2) twist - creates faster, smoother rotation
Tail Press - main SB funds
1) pressure along the length
2) vertical pressure
weight on tail of board - challenges?
will make it hard to pivot over the front leg
Prescription: address body position (more weight on the front leg) - this will allow them to create pivot along the length of the board
fundamental of managing pressure along the length of the board
limited vertical movement - challenges?
- magnitude
- up/down unweighting
- higher level twist
- knee steering (lack of leverage)
MA Fundamentals
- not a single right answer
- does the story make sense
Reference Alignments
- stacked on the board - CoM over the working edge
- shoulders perpendicular to the front foot (slightly open)
- shoulder and hips aligned to the terrain
Fundamentals that go together
- pivot and pressure along the length
- Tilt and pressure along the width
- Twist and pressure song the width
nots sure on these
retraction fundamental
- magnitude of board surface interaction (maxes at the finish (weight over the rear leg), releases as the board decambers (pops), then reengage with the weight over the front foot (initiation))
- pressure along the length (progressive and quick movement)
What is a Level 1 Turn?
most extended or up unweighted
- created through an “up and over” movement (COM moves up and then over the board)
can quickly shift the weight forward, creating a pivot point on the front of the board
Tilt -combo
Of inclination (lean) and Angulation (degree of f/e)
- need both to get board on edge
Which joint changes the most from heel side to toe side?
Hip
- extends on toe
- flexes on heel
Spine
Flexes and extends and rotates
Don’t forget about in observing rider (ankles, knees, hips)
What body part is initialing the turn, and how does this impact the turn?
Shoulders - slow, but powerful - can create z-shaped turns with little initiation or control phases
Ankles - quick, but not as powerful - creates twist
Knee- rotation of femur - twist, but also contributes to lateral movement (pressure) along the length
Hip- can blend with shoulders - can be same challenges
Tilt - day 1
Super critical for the heel slip, really need the combo of inclination and Angulation- one or the other won’t work
AASI Values?
Safety + Fun = Learning
Park Smart
S - Start Small
M - Make a Plan
A - Always Look
R - Respect get respect
T - Take it Easy
AASI - Snowboard Teaching System (STS)
1) Riding Concepts
2) Teaching Concepts
3) Service Concepts
= Learning Pathway
Why does a snowboard slide?
Creates friction with snow, snow melts, board “slides” on water
if too cold, water isn’t created and board sticks
Average turn radius based on side-cut?
Pressing into a cambered board causes?
- around 20 feet
- a shorter turn radius
Rebound
energy that come from the board ‘unbending’ (e.g., de-camber0
Narrow vs. Wide board - performance?
Wide boards are slower to turn, but provide more float
Inclination come for which joint…mostly?
Ankles
Retraction Thoughts
- extend through the control phase of the turn and flex/have “soft” legs at the finish and initiation (to quickly get to the new edge)
- actively flex the ankles (first) and knees (second) towards the CM when moving edge to edge
- move diagonally in a flexed position across the board
- don’t forget to steer!
Teaching Ideas:
- dolphin turns
- front-leg pulls
- back-leg kicks (rebound)
- blend together (pull and kick)
- retract frontside of a mogul, extend down the side and back of the mogul…repeat
Board Slide
Front or Nose of board going over the feature
Lip Slide
Back or tail of the board going over the feature
Indy
backhand & toe-slide
guy was riding for Independent trucks
Mute - now called Weddle
front-hand & toe-side
Weddle was deaf
Melon
Front-hand & Heel-side
Stalefish
back-hand & heel-side
Tony Hawk got canned fish after a competition and called it stalefish…the name stuck
Jump - take-off
- can pop off of both feet (for beginners)
- can ollie and use the tail to flick/snap off the lip of the jump (usually better riders use)
try sliding the board forward (quickly) and snapping off the lip of the jump
need to have great control over the tail of your board to do this
