Domain 1: Basic and Applied Sciences and Nutritional Concepts Flashcards
Don't stress about memorizing muscle actions! Maximum of 2 questions as well as insertion and origin. Tip: Spend time memorizing what the gastrocnemius does.
Obesity
Body mass index of 30 or greater or at least 30 lbs. over the recommended weight for their height
Overweight
Body mass index of 25-29.9 or between 25-30 lbs . over the recommended weight for their height
Blood Lipids
AKA cholesterol or triglycerides. Carried in the bloodstream by protein moles known as HDL and LDL (density lipoproteins)
Diabetes Mellitus
Insulin deficiency that impairs carb usage and enhances usage of fat and protein
Deconditioned
Loss of physical fitness - muscle imbalances, decreased flexibility, and lack of core / joint stability
Proprioception
Cumulative sensory input to the CNS from all mechanoreceptors that sense body position and limb movement
Proprioceptively Enriched Environments
Unstable but controllable physical situation in which exercises are performed that cause the body to use its internal balance and stabilization mechanisms
Muscular Endurance
Muscles ability to contract for an extended period
Neuromuscular Efficiency
Ability of the neuromusclar system to enable all muscles to efficiently work together in all planes of motion
Prime Mover
Muscle that acts as the initial and main source of motive power
Rate of Force Production
Ability of muscles to exert maximal force output in a minimal amount of time
Ligaments
Primary connective tissue that connections bone to bone and provides stability.
Epimysium
Later if connective tissue that is underneath the fascia and surrounds the muscle.
Tendons
Connective tissue that attaches muscles to bone and provide an anchor for muscles to produce force.
Sarcomere
Functional unit of muscle that produces muscular contraction and consists of spearing sections of actin and myosin
Agonist
Prime mover
Squat- gluteus maximus, quadriceps
Synergist
Assist prime mover
Squat- hamstring complex
Nervous System
Communication network
Central Nervous System
Brain and spinal cord; controls and interprets info
Peripheral Nervous System
Only nerves and connects the brain and spinal cord
What are the 3 Main Functions of the Nervous System?
Sensory, Integrative, and Motor
Sensory Function of Nervous System
senses changes in internal or external environment ; stretching (internal) and walking from street to curb (external)
Integrative Function of Nervous System
analyze and interpret sensory info to allow for proper decision making for appropriate response
Motor Function of Nervous System
neuromusclar (nervous and muscular systems) response to sensory information; ex (causing a muscle to contract when stretching too far or changing walking pattern when walking from pavement to sand)
Mechanoreceptors
Sensory receptors responsible for sensing distortion in body tissues
Muscle Spindles
Sense muscular length - activation will cause muscles to tense
Golgi Tendon Organs
Sense muscular tension - activation will cause muscles to relax
Stabilizer
Stabilize prime mover while prime mover and synergies move together
Squat- transverse abdominis
Antagonist
Oppose prime mover
Squat- psoas
Insulin
Stored in the pancreas. Released to bind to glucose to make cell membranes permeable to glucose.
Glucagon
Raises blood glucose (opposite of insulin). It triggers the release of glycogen stores from the liver.
What makes up the cardiovascular system?
heart, blood, blood vessels
What is the typical resting heart rate? (for an untrained adult)
70-80 BPM
Sinoatrial (SA) Node
Special area of cardiac tissue that initiates electrical impulses that determine heart rate (pacemaker of the heart)
Stroke Volume (SV)
Amount of blood pumped out of the heart with each contraction
3 functions of Blood
Transport, Regulate, and Protect
Arteries
Carry blood away from the heart
Capillaires
Site of exchange of water and chemicals between the blood and tissues
Veins
Carry blood back to the heart
Cardiac Output
BPM (beats per minute) and SV (stroke volume)
Muscle involved with inspiration (inhalation)
Diaphragm
Muscles involved with expiration (exhalation)
Abdominal
Bioenergetics
The study of how energy is transformed through various biochemical reactions
Metabolism
All chemical reactions that occur in the body to maintain itself
Substrates
What proteins, carbohydrates and lipids (fats) have to break down to in order to be used for energy
Substrate form of Fat
Triglycerides (stored in fat cells)
Substrate form of Carbohydrates
Glucose and stored as glycogen (stored in liver and muscle cells)
Gluconeogenesis
During negative energy balance (low calorie) amino acids are used to assist in energy production. Formation of glucose from noncarbohydrate sources, such as amino acids.
Kinetic (?) Chain (?)
Motion - Linked (The 3 systems responsible for human movement)
ATP-PC (adenosine tripohsphate-phosphocreatine)
Energy system responsible for providing nearly instant ATP at the onset of any activity
Superior
above point of reference
Inferior
below point of reference
Proximal
nearest to a point of reference
Distal
farthest from a point of reference
Anterior
front of body
Posterior
back of body
Medial
closer to midline
Lateral
farther from midline
Contralateral
opposite side of body
Ipsilateral
same side of body
Frontal Plane
side to side - side lunge/shuffle
Sagittal Plane
front to back - bicep curl/squat
Transverse Plane
midline - throwing/swinging
Concentric
muscle shortens
Eccentric
muscle lengthens
Isometric
no change in muscle length
Altered Reciprocal Inhibition
muscle inhibition caused by a tight agonist which inhibits its functional antagonist
Synergistic Dominance
synergist takes over function for a weak or inhibited prime mover (agonist)
Muscle Imbalance
alteration of muscle length surrounding a joint
OPT Model: Stabilization
ability to maintain postural equilibrium and support joints during movement
OPT Model: Strength
ability of the neuromusclar system to produce internal tension to overcome an external force
OPT Model: Strength 1. strength endurance
muscles’ ability to contract for an extended period
OPT Model: Strength 2. hypertrophy
enlargement of skeletal muscle fibers from resistance training
OPT Model: Strength 3. maximal strength
largest force a muscle can produce in a single voluntary effort
OPT Model: Power
ability to produce the greatest force in the shortest time
Origin
medial connection point (closest to the center of the body)
Insertion
distal connection point (furthest from the center of the body)
Force Couple
