Question 1

How is lactic acid removed from the body

Answer 1

Oxygen combines with lactic acid producing water,carbon dioxide and glucose
These molecules are either used or removed by the body

Question 2

The water produce form lactic acid is how used in the body

Answer 2

The water is excreted in the urine or used elsewhere in the body

Question 3

The carbon dioxide produce form lactic acid is how used in the body

Answer 3

Is transported to the lungs and exhaled

Question 4

The glucose produce form lactic acid is how used in the body

Answer 4

Can be used as a fuel source for further energy production

Question 5

The demand for oxygen will remain until

Answer 5

All the lactic . Acid has been broken down and removed

Question 6

Oxygen debt

Answer 6

The total amount of oxygen required to bring the body back to its resting state
The oxygen needed to break down all the lactic acid produced during high intensity (anaeróbic) exercise

Question 7

EPOC (excess post exercise oxygen consumption

Answer 7

The process of taking in the additional oxygen needed by the body’s cells to remove the lactic acid

Question 8

To achieve EPOC..

Answer 8

Cardiac output and the minute ventilation go up serving to draw more oxygen from the atmosphere into the bloodstream and speeding up the rate of blood transportation

Question 9

Cardiac output

Answer 9

Increases due to an increase in heart rate and stroke volume

Question 10

Minute ventilation

Answer 10

Increases due to an increase in the breathing rate and breathing depth (tidal volume!)

Question 11

Recovery time factors

Answer 11

Strength and fitness
Genetics
Age
Gender
Sleep
Aerobic fitness

Question 12

Why does strength and fitness affect the recovery time

Answer 12

Trained muscles absorb oxygen faster speeding the rate of lactic acid removal

Question 13

Why does genetics affect the recovery time

Answer 13

Some people inherit the ability to recover quickly from their parents
While others naturally take longer for their bodies to return to a resting state

Question 14

Why does age affect the recovery time

Answer 14

Recovery time increase with ages as the body systems becomes less efficient
The efficiency of their cardiovascular and respiratory system decline over time

Question 15

Why does gender affect the recovery time

Answer 15

Women tend to recover more quickly from low to moderate intensity exercise than males

Question 16

Why does sleep affect the recovery time

Answer 16

Quality uninterrupted sleep helps you to recover physically and mentally

Question 17

Why does aerobic fitness affect the recovery time

Answer 17

Fit individuals or endurance Arlete tend to have a larger heart and stronger cardiac muscles enabling them to deliver blood and oxygen at a much faster rate speeding up the removal of lactic acid

Question 18

Why is oxygen needed

Answer 18

to break down the lactic acid after exercise
