Chapter 1 Flashcards
Physiology literally means the?
Exercise physiology is?
The study of all the functions of the body. Exercise physiology is a sub-field of this discipline and focuses on how the body responds to physical exercise.
A single exercise session is a?
A repeated exercise session is?
Single: Acute
Repeated: Chronic Training
Bioenergetics:
Refers to the study of energy transformations and energy exchanges in the human body
Energy is
The ability to do work
Homeostasis
Is the maintenance of equilibrium in a biological system. If follows the idea that your body is constantly trying to remain in balance.
Passive transport across the plasma membrane is accomplished by ? and this essentially?
Diffusion; The idea that one one substance spontaneously moves from a region of greater concentration to a region of lesser concentration.
The difference between levels of concentrations of a substance in two different regions is known as a ?
Concentration Gradient
Facilitated Diffusion
Allows cells that cannot directly pass through the cell membrane to move in/out of the cells.
When a cell expands energy to move substances across a concentration gradient, this process is known as?
Active Transport
Endocytosis
The plasma membrane folds inward, forming a pouch that traps molecules.
Exocytosis
This transport is a reversal of endocytosis. The sac moves toward the outer cell membrane, the membrane of the sac then joins with the plasma membrane, and the contents of the sac are released.
Activity
Any bodily movement produced by the skeletal muscles that result in energy expenditure.
Exercise
A subset of physical activity. It is characterized as being planned, structured, targeted, and is often repetitive.
Physical Fitness
A set of attributes that can be health, skill, or performance related.
Overload
A training effect, a collective changing of the various systems and organs of the body stimulated by the training process to improve or maintain fitness.
