AASI SNOWBOARD TECHNICAL MANUAL Glossary
Terms in black bold appear within this technical manual. Terms in blue bold do not appear in the text but are provided here to enhance the reader’s overall knowledge of terminology used in snowboarding and the mountain environment.
AASI (PSIA-AASI)
The acronym for the American Association of Snowboard Instructors, which, with the Professional Ski Instructors of America forms PSIA- AASI, a nonprofit education association of 31,700 snowsports professionals dedicated to creating life-changing experiences for others through snow- sports instruction.
AASI Snowboard Team
The team of AASI whose members pro- mote, support, and help develop PSIA- AASI education programs and activities at all levels. In this role, they help train snowboard instructors throughout the United States.
abduction
Movement of a limb away from the body’s midline.
ability
A natural or acquired (learned) skill. absorption
Allowing the muscles to relax and joints to flex in response to forces applied to a snowboard, creating a momentary reduction in force.
acceleration
The rate at which an object’s velocity changes over time, including both magnitude and direction.
action plan
The basic recipe for teaching a specific topic.
aft
Toward the tail of the snowboard; see also fore.
agility
The capability to move quickly and easily.
air
The general name for a maneuver performed off the ground while on a snowboard; or to jump over or off of something.
active
Working to cause movement or change; or movements generated to change the snowboard-to-snow interaction.
adaptive
Programs or lessons tailored to the individual needs of people who require specialized equipment or teaching techniques. Adaptive riders may have cognitive, developmental, or physical disabilities.
adduction
Movement of a limb toward the body’s midline.
aerobic exercise
Physical activity that uses oxygen to help meet energy demands, as opposed to anaerobic exercise. The low-to-mod- erate intensity of aerobic exercise allows it to be performed for a sustained period of time. Examples are running, swim- ming, and nordic track skiing.
affective
Refers to the component of the CAP Model that represents a person’s affective development, which involves emotions, motivations, and how he or she feels.
alpine/carving
A style of riding that takes advantage of a hard-boot setup to carve arcs and go fast; often includes a racing component.
American Teaching System (ATS) An evolving system of methods, models, and philosophy of teaching snow- sports – as collected, developed, and disseminated by PSIA-AASI. ATS, which was originally known as the American Teaching MethodTM
, recognizes motor
skills as the basic building blocks of movement progressions. The concepts promoted by AASI are founded in ATS. See also Snowboard Teaching System (STS).
anaerobic exercise
Exercise in which energy is released without the use of oxygen (as opposed to aerobic exercise). The body releases this type of energy via a phosphate energy-delivery system that is later replenished by oxygen. Anaerobic activities that require short bursts of energy include skiing or riding in demanding conditions such as moguls or race courses.
alley-oop
180° turn plus uphill rotation in the halfpipe.
alignment
The positioning of the body so that forces derived from the interaction of the snowboard on the snow pass through the body’s center of mass to produce the intended movement. This is optimized when the snowboard and boots are selected and/or modified to either complement or correct body movement to enhance strength and predictability of movement. Also refers to the process of adjusting boots and bindings to modify a person’s stance.
