Personal Fitness Flashcards
The metabolic process that creates energy from the splitting of glucose to form pyruvic acid or lactid acid and ATP
Glycolysis
System designed to cause action; consists of somatic and autonomic systems
Efferent System
The part of the PNS that sends messages to the CNS
Afferent System
Responsible for voluntary action : skeletal muscles
Somatic System
Processes and activates involuntary action: blood vessels, glands, internal organs
Autonomic System
Consists of the glands and tissues that release hormones. Works with nervous system in regulating metabolic activities.
Endocrine System
- Alter the rate of protein synthesis 2. Change the rate of enzyme activity 3. Change the rate of transport of nutrients through the cell wall. Classifications: Amino Acid Derivatives, Peptides/Protein, and Steroids
Hormones
A byproduct of glycolsis. Gateway to the final common energy producing pathway, the krebs cycle, and it provides acetyl coenzyme A through which fatty acids, and in turn fat, are produced from glucose. Also converts to lactic acid as needed.
Pyruvate Acid
Body system that consists of the bones, joints, connective tissue and muscle.
Musculoskeletal System
The elements of the muscle that actually shorten upon contraction; made up mainly of two types of protein: actin and myosin
Myofilaments
A byproduct of glucose and glycogen metabolism (glycolysis) in anaerobic muscle energetics. Pg. 110 for details
Lactic Acid
The science of the structure of the human body
Anatomy
The science concerned with the normal vital processes of animal and vegetable organisms
Physiology
An increase in muscle fiber size in response to strength training.
Hypertrophy
An increase in number of cells in a tissue or organ, excluding tumor formation.
Hyperplasia
A corticosteroid that causes a breakdown of protein in muscles
[IMGPATH:]/sdcard/StudyDroid/Personal Fitness -47-true.jpg
An abnormal increase of ketone bodies in the body ; usually the result of a low-carbohydrate diet, fasting or starvation.
Ketosis
Synarthroidal: Joint with no seperation or articular cavity
Diarthroidal: Feely movable joint with an articular cavity.
2 Classifications of Joints
White, fast twitch, fast shortening speed. Energy transfer from aerobic and anaerobic sources.
Type 2A Muscle Fiber
White, fast twitch fiber. Most rapid shortening and greatest anaerobic potential.
Type 2B Muscle Fiber
Parallel
Fusiform
Triangular
Multipennate
Unnipennate
Bipennate
Name the 6 major muscle fiber arrangements
The science or study of movement , dealing mainly with the muscles and muscsle functions
Kinesiology
Muscle that plays a secondary role to the prime mover involved.
Assistant Mover
When both the agonist and antagonist undergo contraction.
Co-Contraction
