2. Learning Outcomes
• Characteristic of Muscle Tissue
• Function of Skeletal Muscles
• Types of Muscle Fibres
• Muscle Name
• Modes of Muscle Contraction
• Benefits of Strength Training
• Ways to train your Muscles
• Types of Stretching
• How to stretch your muscles
4. Excitability
• A process where muscle tissues in our
body send signals to the brain and the
brain tells the body to move out
• All this happen within a fraction of a
second
5. Contractility & Extensibility
• Our muscle work by contraction
• After muscle contracts, it must extend to
release energy which it had stored
• Hence, muscles work in pair
6. Elasticity
• If muscles were not
elastic, we would
have been longer
and taller with
each extension.
• Elastic to a certain
limit
• Beyond which it
will break
7. Function of Skeletal Muscles
• Produce Movement
• Maintain posture
• Maintain body temperature
9. Maintain Posture and Body Position
• Tension in our skeletal
muscles maintains
body posture
10. Maintain body temperature
• Muscle contraction require energy
• Heat release by working muscles keep our
body temperature in the range for normal
functioning
15. 2 types of muscle fibre
• Fast twitch
Do not need oxygen to create energy,
Can produce faster movement
Tired out easily
Eg: Sprinting, jumping
• Slow Twitch (Enduring Sports)
Need oxygen to create energy
(Stored of glycogen)
Slower production of movement
Sustain longer
Eg: Jogging, Tai Chi
22. Benefits of Strength Training
• Improve physical performance due to
increase in muscles’ size, strength and
endurance
• Improved physical appearance
23. Benefits of Strength Training
• Increased Metabolic Efficiency
(Ability to burn excess calories)
24. Benefits of Strength Training
•Decrease risk of sustaining injury
(Sprains and strains)
Can hold our joints stronger
Note: When training, we need to train opposing muscle group
to prevent unbalance muscle development
25. Ways to train your muscles
Trapezius
Dumbbell Shrugs Upright Rowing
You can use 1.5L water bottle instead of dumbbells
42. Static Stretching
• Hold a stretch
position for at least 15
sec
• No bouncing or rapid
movement
• A mild pulling
sensation is felt
• No pain is felt
44. Dynamic Stretching
• Controlled movement
to take you to your
limits of range of
motion
• No bouncing or rapid
movement
• Eg: Controlled leg
swings, arm swings or
torso twists
45. Ballistic Stretching
• Use momentum of a
body
• To force it beyond it
normal range of
motion
• Bouncing in and out
of a stretched position
Eg: bouncing to touch
your toes
46. How to stretch your muscles

Gluteals Stretch Quadriceps Stretch
47. How to stretch your muscles
Abdominal Stretch Latissimus Stretch
(Cobra Stretch)
Pectoral Stretch
48. How to stretch your muscles
