Study Guide Vocab Flashcards
Nervous System Functions
Sensory
Integrated
Motor
Peripheral Nervous System
Nerves connecting the CNS to the rest of the body. Made up of the Somatic (voluntary) and the Autonomic (involuntary heart or digestive)
Motor neuron
Transmit nerve impulses from CNS to effector sites
Golgi Tendon Organ
Regulates changes in muscle TENSION
Muscle Spindles
Regulate changes in muscle LENGTH
Fascia
Outer layer of connective tissue surrounding the muscle
Type I Muscle Fibers
Slow twitch - slow to fatigue
Type II Muscle Fibers
Fast twitch - Quick to fatigue
Local Stabilization System
Attach to vertebrae - Consists of the transverse abdominis, internal oblique, pelvic floor, and diaphragm
Global Stabilization System
Attach to the pelvis and spine - papas major, external oblique, and recurs abdominous
Movement System
Attached spine and pelvis to extremities - latissimus dorsi, hip flexor, hamstring, quadriceps
Athrokinetics
Joint motion
Hinge Joints
Elbows, Ankles - Sagital plane motion
Ball In Socket
Shoulder, Hip - movement in all three planes
Cardiac Muscle
Short muscles
Atria
Receives blood from veins
Right Atria
Gathers deoxygenated blood to the heart
Left Atria
Gathers OXYGENATED blood from the lungs
Right Ventricle
Pump deoxygenated to the lungs
Left Ventricle
Pump OXYGENATED blood to the body
Arteries
Carry blood from the heart to body
Veins
Carry blood back to the heart
Resting Oxygen Consumption
(VO2) = 1 metabolic equivalent
Aerobic
Running, swimming, cross country - focuses on heart health
Anaerobic
Weight Lifting, calisthenics - targets muscle growth
Torque
A force that produces rotation
1st Class Lever
Fulcrum is in the middle - nodding your head
2nd Class Lever
Resistance is in the middle - calf raise
3rd Class Lever
Effort is in the middle - bicep curl
Planes of Motion
Frontal - sagittal - Transverse
Frontal Plane
Divides body from front and back - anterior Posterior axis - Adduction/Abduction, lateral movements, jumping jacks
Sagittal Plane
Divides the body from left to right - medial lateral axis - push up, bicep curl
Transverse Plane
Divides the body from top to bottom - longitudinal axis - rotation exercises, golf
Obesity
BMI over 30 or 30 pounds over the recommended weight for their height.
Muscle Imbalance
Weak muscle surrounding a joint
Force Couple
Muscles working together to produce one movement
Energy Systems
ATP-PC
Glycolytic System
Oxidative System
ATP-PC Energy System
High power/Short duration
10-15 seconds
Glycolytic Energy System
Moderate power/moderate duration
30-50 seconds
Oxidative Energy System
Long term duration
6 mile run
3 mile walk
Klebs Cycle
Sequence of chemical reaction that continues to oxidize glucose
E.P.O.C.
Excess Post Oxygen Consumption
Davis’s Law
Soft tissue models along the lines of stress
Carbohydrates
4 calories/gram
Monosaccharides, disaccharides, fiber
30-60g during workouts longer than 1 hour
Glycemic Index
The rate at which carb sources raise blood sugar and spike insulin
High = >70 Moderate = 56-69 Low = <55
Protein
4 calories/gram
Linked together by peptide bonds
Water Consumption
3 liters for men
2.2 liters for woman
Protein Intake Requirements
Sedentary adults - 0.8g/kgBW or 0.4 g/lbsBW
Strength Athletes - 1.2gs/kgBW or 0.8gs/lbBW
Endurance athletes - 1.4gs/kgBW
Intake Requirements for Carbs
6-10g/kgBW
28-38 grams from fiber
45-65% daily diet
