Starter

Unit 4 - The Sports Performer in Action

What is the cardiorespiratory system?

Use your textbooks to answer this question (page 108).

P5 - Describe the function of the three energy system in the production and release of energy for sports performance

M5 - Using two selected sports, explain how the body uses both the anaerobic and aerobic energy systems

8 short-term effects of exercise on the cardiorespiratory system

  • Increased heart rate and blood flow
  • Increased breathing rate
  • Sweat production and skin reddening
  • Redistribution of blood flow
  • Lactic acid in the blood
  • Cardiac output
  • Blood pressure
  • Increased tidal volume

Short term effects of exercise on the cardiorespiratory system

BTEC Sport

Unit 4 - The Sports Performer in Action

Learning Aims:

2A. P2 - Describe ways in which the cardiorespiratory system responds to short-term exercise

2A. M2 - Explain responses of the cardiorespiratory system to short-term exercise

Starter

Why do you think a 100m sprinter would struggle to be able to complete a marathon?

Task

Using page 106, find out the short-term effects of exercise on the musculoskeletal system and write notes in your exercise book.

What do you think might be some of the signs that you are running out of energy?

What is the musculoskeletal system?

Energy Systems

Use your textbooks to answer this question (page 106).

2A. P1 - Describe ways in which the musculoskeletal system responds to short-term exercise

2B. M1 - Explain responses of the musculoskeletal system to short-term exercise

5 short-term effects of exercise on the musculoskeletal system

  • Increased production of synovial fluid

  • Increased range of movements in the joints

  • Micro-tears in muscle fibres

  • New bone formation

  • Increased metabolic activity

Discuss:

In groups, discuss what you think are the physical signs that a weightlifter's training programme is working. What happens to their body to make sure it can cope with increased training?

When we talk about long-term adaptations to exercise, we mean changes than happen in your body after 6 - 8 weeks!

Long-term adaptations of the musculoskeletal system

Starter - Kahoot!

Lesson objective:

Task:

P3 - Summarise, using relevant examples, long-term adaptations of the musculoskeletal system to exercise

P - Using pages 114-117. Complete the worksheets I have given out.

M - Using pages 114-117. Make notes on the long-term benefits for bones, joints and muscles.

M3 - Explain long-term adaptations of the musculoskeletal system to exercise.

Peer Assessment

In pairs, present your findings to your partner. Discuss these short-term effects of exercise on the cardiorespiratory system.
