manual
A slide on the tail of the board; to perform such a trick.
Maslow’s Hierarchy
A hierarchy of needs depicted as a pyramid developed by Abraham Maslow. People are motivated to fulfill basic needs before striving for subsequent needs and so on.
mass
The property of an object that causes it to have weight in a gravitational field; the amount of material that an object contains. Mass is commonly but impre- cisely used as a synonym for weight.
massed practice
Frequently repeating a small task list. mature phase
(of motor development) The last phase of motor skill develop- ment when learned movements become automatic, without conscious thought.
McTwist
A snowboard flip in a halfpipe, created when a rider approaches the backside wall (heelside edge) and flips forward as in a barrel roll and adds rotation with the head and shoulders.
mechanics
The essential actions of the snowboard and the basic body movements present in all snowboarding, regardless of terrain, snow conditions, pitch of the slope, and speed of descent.
medial
Pertaining to the middle; nearer the middle of the body, as opposed to “lateral.”
method
A snowboard grab in which the rider grabs the heelside edge with the lead hand while positioning the board behind the body, usually with the hips extended.
mini pipe
A small halfpipe feature with short walls and gentle transitions, built with a snowcat and usually used in terrain-based-teaching.
movement analysis (MA) The process of observing a movement, evaluating the relevance and effect of that movement on other movements and the action of the snowboard, and prescribing changes for enhanced effi- ciency, effectiveness, and performance.
movement blends
Combining body movements to attain different riding outcomes.
movement concept
The aspects of snowboarding that describe how we move on a snowboard; flexion/extension and rotation; see also fundamental movements.
multiple intelligences
A system for identifying comprehensive categories of human mental capabilities.
muscle
Tissue composed of cells that can shorten (contract) and lengthen (relax) to stabilize or move joints.
objective
Without prejudice or bias; or a goal. observation phase
The phase in the movement analysis model in which the instructor identifies body movements and the action of the snowboard on the snow.
moguls
The series of mounds (or “bumps”) that naturally form on a run when skiers and snowboarders push the snow into piles as they execute short-radius turns. The steeper the slope, the bigger the bumps and deeper the troughs between bumps.
momentum
Inertia in motion; defined as an object’s mass multiplied by its velocity. Speeding up, slowing down, and turning are all changes in momentum. An external force must be involved to change momentum.
Motor Learning Cycle
A series of steps the instructor cycles through to assist students with skill acquisition. The four elements of the cycle are static (or stationary), simple, complex, and freeride (or whole).
National Ski Patrol (NSP) An association whose members support and participate in the snowsport and outdoor recreation community by provid- ing educational training and emergency care and rescue services.
neutral stance
Not extreme; or posture in which the alignment of the body is centered.
Newton’s Laws of Motion Fundamental laws of physics that describe the relationship between the forces that act on a body and the motion that results. • Newton’s First Law: An object remains at rest or continues to move in a straight line at a constant speed if there are no unbalanced forces acting on it.
• Newton’s Second Law: When the forces acting on a body are not balanced, the net force causes the body to accelerate.
• Newton’s Third Law: Every force has an equal and opposite reaction force.
nollie
To load the nose of the board, then pop off the ground using the loaded energy; or a maneuver containing these elements.
nose
The front, or tip, of a snowboard. nose roll
A type of 180 in which only the nose of the snowboard remains in contact with the snow.
model
An analogy in which concepts are related to a familiar device or system to facilitate understanding.
National Ski Areas Association (NSAA)
A national trade association for ski and snowboard area owners and operators.
