quiz 16 Flashcards
isolation exercises
typically involve dynamic or isometric muscle actions designed to isolate specific core musculature w/o the contribution of the lower and upper extremitites
free weight training method
cause greater activiation of stabilizer muscles and offer the ideal combination of speificity and instability
machine training
machines offer greater stability and may result in a better ability to target specific muscle groups
instability devices
exercises performed on unstable surfaces or devices whose usage stems from use in PT settings, may inc. core muscle activation but can lower force output by 30% or more
constant external resistance
most common method for applying resistance, represented by traditional methods such as free weights, the external load remains constant throughout the full ROM and better represents real-life activities
accommodating resistance
aka semi-isokinetic resistance. allows for the speed of the movement to be controlled thru the full ROM. may not provide adequate training stimulus when compared to traditional resistance methods
general guidelines to exercise
exhale during concentric portion of the exercise, inhale during eccentric phase
benefits of bodyweight training
specific to each individual, strengthens several muscle groups at once, develops relative strength, improves body control, low-cost training alternative
anatomical core
the axial skeleton and all of the soft tissues with proximal attachments that originate on the axial skeleton
core training
suggested that increasing core stability will result in a better foundation for force production in the upper and lower extremities
ground based free weight activites appear to offer similar, or in most cases, greater activation of the core musculature when compared to traditional isolation exercises designed to engage the core
variable resistance
attempts to alter resistance so the muscle maximizes force throughout the full ROM. usually involves chains or resistance bands
