A4+5 Responses to the skeletal systems

Question 1

What are the responses of the skeletal system split into?

Answer 1

• short-term (immediate)
• long-term (over a period of time)

Question 2

What is a response of short-term affects?

Answer 2

• acute responses

Question 3

What is a response of long-term affects?

Answer 3

• adaptations or chronic responses

Question 4

Acute responses …

Answer 4

• when the body makes an immediate change or response

Question 5

Chronic responses …

Answer 5

• adaptations that take place over a long period of time

Question 6

Why is it essential to to complete a thorough warm up in order to give the skeletal system time to produce the following…?

Answer 6

• increase in synovial fluid at the joints (to give extra lubrication and protect the joint capsule)
• the synovial fluid becomes less ‘viscous’ and the range of movement at the joint will increase as a result
• this will provide increased nutrients to the articular cartilage
• increased uptake of mineral within the bones
• the body will absorb minerals like calcium in order to develop bone strength
• a bone becomes stronger and denser the more you put demands on it

Question 7

What are examples of acute responses?

Answer 7

• breathing rate increase, heart rate increase, increased blood pressure and sweating

Question 8

What are the chronic responses?

Answer 8

• adaptations that lead to improved fitness for sports participation and reduced health risk
• exercise will increase bone density (less likely to fracture)
• long-term physical activity leads to developed ligament strength (and elasticity) resulting in increased flexibility
