NESTA PT Exam Chapter 2 Flashcards
Define Exercise Physiology
the study of the cellular reactions within
the body during and after exercise.
the sum total of all human physiological responses and adaptations to physical activity.
(Body Builder Muscle vs Gymnist Flexibility)
What Does (GAS) Stand For?
General Adaptation Syndrome (GAS)
Define “Detraining”
Too much time between exercise bouts (recovery time) so gains are lost (negative training adaptations)
Define “Overtraining”
The effect of stress (exercise) that is too intense (overload)
and/ or there is an insufficient recovery time
Define (GAS) and its 3 Stages “ARE”
The process of adaptation due to stress (i.e. exercise)
3 Stages = ARE
Alarm Stage - the “flight or fight” stage where the body prepares for physical activity.
Resistance Stage, where the body attempts to adapt in order to cope with the stress. enters the
Exhaustion Phase. if the stress persists the body’s resources are depleted and the body
How many systems are there in the body and what are they called?
11 systems called:
- *Nervous System**
- *Muscular System**
- *Skeletal System**
- *Circulatory System**
- *Respiratory System**
- *Gastrointestinal System**
- *Integumentary System**
- *Urinary System**
- *Reproductive System**
- *Immune System**
- *Endocrine System**
Nervous System
The body’s means of perceiving and responding to events in the internal and external environments.
Muscular System
Specialized cells of the body with contractile ability in order to create movement.
Skeletal System
Creates the basic structure of the body, giving framework to the muscular system to allow move- ment. Also the site of blood cell formation.
Circulatory System
The “transport system” of the body (ex: O2, CO2, fuel, nutrients, waste, immune cells, hormones, etc.). Often divided into the cardiovascular system and the lymphatic system.
Respiratory System
Brings in O2 from the air and excretes CO2 and H20.
Gastrointestinal System
Uses the processes of ingestion, digestion, ab- sorption, and metabolism to convert consumed food into smaller molecules for use in the body and excretes the unused remnants.
Integumentary System
The covering of the body (i.e. skin, hair, nails). Provides protection, structure and serves as a sensory interface with the external environment.
Urinary System
Creates, stores and eliminates urine (which con- tains by-products (many nitrogen rich) of cellular metabolism).
Reproductive System
Consisting of the gonads and the sex organs for the development of offspring.
