Issa Strength & Conditioning, Strengthand Conditioning EXAM ISSA/377 Q/A
Neural Circuitry that travels outside the spinal cord - -Peripheral nervous
system
-A sensory receptor within a muscle that detects changes in length and
helps regulate contraction - -Muscle Spindle
-Branches of the cell body that act as receivers, collecting information from
other neurons - -Dendrites
-Muscle contraction is triggered when the following chemical
neurotransmitters binds to receptors on the muscle - -acetylcholine
-Division of the peripheral nervous system controls voluntary movement - -
somatic nervous system
-Type of motor unit can contract for many hours - -Slow of Motor Unit
-Type of motor unit has a large motor neuron & consists of a large bundle of
type IIx muscle fibers - -Fast Fatiguable (FF)
-Voluntary movement starts in - -Cerebral Cortex
-The process that allows a muscle spindle to contract at the same rate as
the muscle where it resides - -Alpha-gamma Co-activation
-How many nerves are contained within the peripheral nervous system - -43
Pairs
-The muscular system includes how many muscles - -approximately 650
-Muscle fiber type that's the largest & produce the most amount of force - -
Type IIx
-Cross-bridge cycle requires energy, which is provided by - -ATP hydrolysis
-The function of epimysium is too - -Protect muscle from friction against
other muscles or bone.
-Muscle fiber type has a very small amount of mitochondria - -Type IIx
, -Make-up of a person's muscle fiber ratio - -It can't be changed to a large
degree
-Training with heavy loads causes - -Equal growth of type I and type II fibers
-Functions like girdles & guy wires to provide an interconnected structure - -
Fascia
-Three possible mechanisms for inducing hypertrophy - -Mechanical
tension, metabolic stress, muscle damage
-functional units that can make a muscle shorten - -Sarcomere
-Found within the appendicular skeleton - -Bones of the upper & lower
extremities
-Movement between 2 adjacent vertebrae is made possible by - -Facet
Joints
-Wolff's Law - -The body responds by increasing or decreasing the bone's
diameter
-Cartilage plays important rolls such as - -Bone development
-Mature bone cells that maintain a bone's matrix - -Osteocytes
-Bone on bone contact that results in joint pain - -osteoarthritis
-Elastin allows tissues too - -regain their original shape after being stretched
-The main part or shaft of a long bone - -Diaphysis
-Frontal plane is an imaginary plane that divides the body into - -Anterior &
posterior
-Angle that a joint rotates around its axis - -The direction of rotation
-The smallest blood vessel - -Capillaries
-Create more muscular support when performing an intense exercise - -
Bracing effect of a tight core
-Largest lymphatic organ in the human body - -Spleen
-One of the main functions of the respiratory system - -removal of waste
products of metabolism
,-Normal amount of air displaced between inhalation & exhalation - -Tidal
Volume
-Major glands of he endocrine system - -Hypothalamus
-The amount of blood pumped through the heart per minute - -Cardiac
output
-Peripheral resistance - -The amount of resistance to blood flow in the
arteries.
-Plasma makes up ____ percentage of blood volume - -55%
-Right atrium receives deoxygenated blood from the body & moves it too - -
The right Ventricle
-Law of conservation of energy states that energy - -cannot be created or
destroyed
-In short term, metabolic acidosis can - -impair muscle power & energy
production
-Process of making ATP from glucose - -Glycolysis
-Cytoplasm & Sarcoplasm - -Sarcoplasm is where the action of the
phosphates system & the reaction components take place
-The time it takes to fully replenish stored phosphocreatine after maximum
effort exercise - -15-25 minutes
-The formation of glucose from noncarbohydrate sources - -
gluconeogenesis
-Lactate threshold corresponds with - -Rapid drop in physical output &
performance
-Actions occur within the mitochondria during the first 10-30 seconds of
maximal activity - -Mitochondria absorb protons (H+)
-Enzyme breaks down triglycerides into fatty acids during lipolysis - -
Hormone-sensitive lipase
-Fuel type produces 106 ATP - -Fatty acids
-Mechanics are divided into two categories - -dynamic and static.
, -Class of lever is the fulcrum (axis) located between the effort and the load -
-First-class
-a state of no acceleration, with the body at rest - -Equilibrium
-Point at which both body mass & weight are equally distributed - -center of
gravity.
-Force is a product of - -mass times acceleration.
-shearing refers too - -cutting or breaking.
-The muscles responsible for protraction of the scapulothoracic (ST) joint - -
pectoralis major.
-Adduction - -Movement toward the midline
-Primary wrist movements include - -ulnar deviation
-Ankle is formed by three bones; the tibia, the fibula, and - -Talus
-When using skinfold calipers to assess body composition, how should the
skin of the suprailiac region be pinched - -At a 45-degree angle
-it is better to think of posture as - -ideal or not ideal.
-when muscles surrounding a joint are abnormally weakened or overactive,
thus limiting a joint's movement - -Muscle imbalance
-When conducting the Rockport one-mile walk test, when should the
participant's heart rate be measured - -At the end of the test only
-Why is the three-minute step test used less frequently than the Rockport
one-mile walk test and the Cooper 12-minute run test - -It is less effective
and has a lower percentage of participant completion
-the lunge assessment - -The coach will observe the lunge movement with
little or no coaching.
-When conducting a standard squat assessment, the participant should be
observed - -anterior, posterior, and lateral positions.
-a gait assessment - -A gait assessment requires a coach to observe the
client while walking.
