Chapter 1 Exercise Physiology

Front 1

Main advantage of the metric system

Back 1

Multiples of its basic units are expressed in factors of

10 using prefixes attached to the basic unit

Front 2

Work

Back 2

Product of force and the distance through which that force acts.

Work= force x distance

Front 3

In the calculation of work, what unit represents force

Back 3

Kp=kilopond

The effect of gravity on a mass of 1 kilogram

Front 4

Power

Back 4

How much work is accomplished per unit of time

Describes the rate at which work is being performed

Front 5

Percent grade

Back 5

Amount of vertical rise per 100 units of belt travel

I.g:

10% grade

Diatance=10 m

10x10=100 m of the belt travel

Front 6

What's this calculation?

Back 6

Total amount of work output

Front 7

Power is defined as

Back 7

Work /time

Front 8

Measuring a person's metabolic rate via the measurement of heat production

Back 8

Persons body heat raises the temperature of the circulating water around the chamber

Temperature change per unit of time

The evaporation of water represents the heat loss from the person. And is then added to the total heat picked up by the water

Front 9

Open circuit spirometry

Back 9

Used to measure oxygen consumption

Front 10

Direct calorimetry

Back 10

Measurement of heat production as an indication of metabolic rate

Front 11

Indirect calorimetry

Back 11

Estimates metabolic rate via the measurement of oxygen consumption

Front 12

Yo

Back 12

Yo

Front 13

Finding metabolic rate

Back 13

Convert the vo2 max into ml first

Front 14

The capacity to convert energy expenditure into work

Back 14

Efficiency

Front 15

Steady state

Back 15

Front 16

Explain

Back 16

Serves to restore normal values odd a variable to maintain homeostasis

Front 17

Back 17

Responds in the same direction as the stimulus

Front 18

Gain

Back 18

Precision to which a control system maintains homeostasis.

Large gain is more capable of correcting a disturbance in homeostasis. Pulmonary and cardiovascular systems are large gain systems

Front 19

The components of a negative feedback loop

Back 19

Sensor

Control center

Effector

Front 20

A series of interconnected connected components that maintain a chemical or physical parameter of the body near a constant value

Back 20

Biological control system

Front 21

Examples of?

Back 21

Homeostatic control

Front 22

How can exercise disrupt homeostatic control

Back 22

Causes changes in ph,o2,co2, and temperature in cells

Front 23

Adaptation

Back 23

Change in the structure and function of a cell or an organ system that results in an improved ability to maintain homeostasis during stressful conditions

Front 24

The improved function of an existing homeostatic system

Back 24

Acclimation

Front 25

How does the body adapt to exercise

Back 25

Through cellular changes

Cell signaling mechanisms

The ability of cells to detect change in their internal environment and correctly respond

Front 26

Intracrine signaling

Back 26

Chemical messenger produced inside the cell triggers a signaling pathway within the same cell leading to a specific response

Front 27

Juxtacrine signaling

Back 27

Communication of cell to cell contact through small junctions that connect the two cell membranes

Front 28

Autocrine signaling

Back 28

Cell produces and releases a chemical messenger into the extracellular fluid that acts upon the cell producing the signal
