Answer 1

basic [exercise physiology]

Question 2

___ science describes, explains , and uses bodys adaptation response to exercise training to improve human physical potential

Answer 2

applied [exercise physiology]

Question 3

studies how body’s structures and functions are altered when exposed to acute and chronic bouts of exercise

Answer 3

exercise physiology

Question 4

applies exercise physiology concepts to an athletes training for performance/competition

Answer 4

sport physiology

Question 5

-maintenance of a constsant internal environement with unstressed conditions and dynamic constancy

Answer 5

homeostasis

Question 6

balance between demands placed on body and the physiological response to those demands

Answer 6

steady state

Question 7

• contracting muscles
• heat build up
• plateau point - SS but not homeostasis where balance betwen heat generated and heat released is conduction/sweating

Answer 7

steady state submaximal exercise

Question 8

goal of control sys of the body

Answer 8

=regulate some physiological variable at or near constant value to maintain homeostasis, not absolutely constant/ variations around set point of dynamic consistency

Question 9

series of interconnected components that serve to maintain a physical or chemical parameter at or near constant

Answer 9

biological control systems

Question 10

biological control systems include __,__,and ___

Answer 10

receptor , integrating center, effector

Question 11

capable of detecting changes

Answer 11

receptor (bio control sys)

Question 12

assesses input and initiates response

Answer 12

integrating center (bio control sys)

Question 13

corrects changes to internal environment and removing stimulus

Answer 13

effector (bio control sys)

Question 14

most biological control systems ____ the inItial distubrance in homeostasis with negative feedback (opposite to stimulus)

Answer 14

REVERSES

Question 15

• DEGREE TO WHICH CONTROL SYS MAINTAINS CONTROL
• system with large gain is more capable of maintaining homeostasis
• SYS W/ SMALL GAIN IS LESS CAPABLE OF MAINTAINING HOMEOSTASIS

Answer 15

gain of a controls ystem such as reg of BP

Question 16

• exercise in hot/humid environ
• may not be able to maintain steady state
• severe disturbances in homeostasis can occur /fatigue

Answer 16

maximal exercise

Question 17

\_\_ exercise
-lactic acid -> acidosis
-inc in CO2 production, inc in O2
RESULTS IN
-inc heart rate, blood flow and pulmonary ventilation

Answer 17

Heavy

Question 18

During 60 minutes of submaximal exercise, the body temperature reaches a plateau after 35-45 minutes, this is an example of

Answer 18

steady state

Question 19

changes in arterial blood across time during resting conditions is an example of

Answer 19

homeostasis

Question 20

overall goal of a control sys is to regulate a physiological variable

Answer 20

at or near a constant value

Question 21

decreasing the original stimulus that triggered the control system is called

Answer 21

negative feedback

Question 22

the precision with which a control system maintains homeostasis is called

Answer 22

gain

Question 23

Severe disturbances in homeostasis result in fatigue and ultimately

Answer 23

cessation of exercise

Question 24

during heavy exercise or exercise in hot/humid environ, you may have…

Answer 24

disturbances in internal environm disruption of steady state and rapid responses of control systems
