The muscular system allows movement through skeletal muscles that contract and pull on bones. There are two main muscle types - fast twitch muscles that contract quickly and are suited for activities like sprinting, and slow twitch muscles that contract slowly and are suited for endurance activities like long distance running. Tendons connect muscles to bones and transmit force to allow movement, working with muscles to pull bones and cause motion.
2. Function of the muscular system
• Skeletal muscle forms
all of the ‘red meat’
around your body.
• They are what gives
your body shape.
• Over 40% of your body
weight is skeletal
muscle
3. Function of the muscular system
• Skeletal muscle allows
us to move, by
contracting
(shortening), and
pulling on our bones.
• Skeletal muscle has a
major part to play in
sport and exercise.
6. Which muscle type is more suited to
what activity?
• Running a marathon
• Weight training
• Playing football
• Swimming 100m
• Sprinting out for a
centre pass
• A full-court press in
basketball
• Serving in tennis
• Walking
7. Role of tendons
• Tendons are a tough band
of ‘connective tissue’
• They connect muscle to
bone.
• Tendons are built to endure
tension.
• Tendons are similar to
ligaments except that
ligaments join one bone to
another.
• Tendons and muscles work
together to pull on a bone
and make it move
9. Task
• Using the sticky labels, write down the muscle
names, and see how many you can stick on
your partner in the correct position.
• Complete the blanks on the worksheet
• Revise this week, as you will be tested next
week, and any not attaining 70% will have to
re-sit until they do!
