Trained Vs Untrained HR

Question 1

What are the two types of responses for trained vs untrained athletes to training?

Answer 1

Acute - immediate response

Chronic - long term response

Question 2

What are four chronic affects on the heart of a trained or untrained athlete?

Answer 2

• Cardiovascular Hypertrophy
• Increased Chamber Sizes
• Increase in Stroke Volume
• Decrease in Heart Rate

Question 3

How does a trained individual adapt their training?

Answer 3

• Increased the no. of red blood cells (Training at higher higher altitudes)
• Training varies on genetics (positive and negative)
• Cardiac hypertrophy(heart increases in strength and size)
• Chambers of the heart increase in size increasing stroke volume

Question 4

What is the main factor of a trained body we must remember?

Answer 4

Heart increases so stroke volume increases,therefore, there is no need for it to beat more often

Question 5

What is the likely SV for an untrained athlete during maximal exercise?

Answer 5

112mL

Question 6

What is the likely stroke volume for a trained athlete?

Answer 6

130mL

Question 7

What is the likely stroke volume for an endurance athletes?

Answer 7

180mL

Question 8

Is HR lower or higher in a trained athlete than in a untrained athlete?

Answer 8

Lower

Question 9

What is the likely HR of an endurance athlete?

Answer 9

Below 40bpm

Question 10

What is the likely HR of an untrained athlete?

Answer 10

90bpm

Question 11

What are the effects of regular training on HR?

Answer 11

• Lower RHR
• Lower HR during sub-maximal exercise
• Slower HR increase
• Lower HR during exercise
• Faster recovery rate

Question 12

How does training affect stroke volume and heart rate in an athlete?

Answer 12

Increased Stroke volume and lower heart rate allows the body to move blood more efficiently to the working muscle of the athlete as less beats is needed due to the volume pumped per beat being higher

Question 13

What is the function of chemoreceptors?

Answer 13

• Detect increase in CO2

- Detect chemical changes

Question 14

What is the function of baroreceptors?

Answer 14

Detect changes in bp to increase/decrease HR

Question 15

What are the benefits of exercise?

Answer 15

• Heart pumps greater volume of blood
• Lungs become stronger
• Increase in metabolic rate
• Reduction in health risk factors
• Reduced chance of cardiovascular diseases
• Lowers risk of some cancers
• Reduced risk of type 2 diabetes & metabolic syndrome
• Able to develop more blood cells
• A decrease in resting heart rate
