Improving muscle strength (non-statutory)

Introduction to the human skeleton and muscles

Unit Summary

This unit explores the role of skeletons and muscles in humans and other animals for support, protection, and movement. It involves setting up practical enquiries, making observations, measuring accurately, recording findings, and using results to draw conclusions and suggest improvements.

Lesson Summary

You will learn to design a fitness circuit to improve muscle strength.

Key Notes

  • Muscles that are found close together on your body often help you to perform similar movements.
  • Athletes focus their training on different muscles depending on their sport .
  • Humans can improve the strength of their muscles through exercise, such as lifting weights.
  • A complete fitness circuit should aim to improve the strength of different muscles in the body.

Vocabulary To Learn

  • muscles: Muscles are parts of the body which pull, causing bones to move.
  • athlete: An athlete is a person who is good at sports or physical exercise, especially one who competes in organised events.
