2. 8 th Grade Health

3. 1. How do my muscles work? 2. How can I get stronger?

4. Students will…  review location and function of basic muscles  discover how a strong muscular system affects health, performance and appearance  Recognize the relationship between an active lifestyle and a healthy diet in the development of a strong muscular system

5. Students will…  Name the location and function of basic muscles of the human anatomy  Describe how an active lifestyle with exercise promotes muscle growth  Explain how a healthy diet is necessary for a strong muscular system

6. Instructions: 1. Number your paper 1-11 2. Write the NAME of the muscle next to the number on the diagram on the following slide 2-3 minutes

7. Muscle Names Abdominals Biceps Deltoids Gastrocnemius Gluteals Hamstrings Latissimus Dorsi Pectorals Quadriceps Trapezius Triceps 1 2 4 3 8 7 6 5 9 11 10

9.  Follow along to the video about how the skeletal system and muscular system are related. Do you remember the skeletal system from 5 th grade?

10. 1. Cardiac Muscle 2. Smooth Muscle 3. Skeletal Muscle

11. 1. Involuntary  automatic 2. Voluntary  we control the movement

12. Control: Involuntary Appearance: Striped Location: Only in the heart

13. Control: Involuntary Appearance: Smooth Location: Digestive System Blood vessel walls

14. Control: Voluntary Appearance: Striated Location: Attached to bones

16.  Read Muscles for Life Student introduction (3.26)  Complete the worksheet as you read along  If you finish early, get out a book or other homework as you wait patiently for the class to move on together  15-20 minutes

17. Movement Assists in: Breathing, digestion, and pumping of the heart

18.  Provides long-term health benefits  Enhances performance in activities  Provides improvements in appearance

19. Flexors  decrease angle at joint Extensors  increase angle at joint

20. Skeletal Muscles: Working in Pairs

21. Adductors  towards center of body Abductors  away from center of body

22. Allows a person to…  perform daily daily activities with greater ease (muscular strength)  enhance quality of life by accomplishing more (muscular endurance)  Increase in bone density = decrease risk of osteoporosis  improve posture and alignment to reduce low back problems  decrease risk of injury caused by everyday mishaps

23. Muscles get stronger according to the amount of stress or work that is placed on them. Resistance training increases: Muscular strength, muscular endurance, power, speed, agility, coordination and balance

24. Body Composition = The percentage of fat-free mass vs. fatt mass Muscle mass burns calories! Improved appearance leads to higher self- esteem

28. WARM UP Finish filling in the location of the muscles on your circuit worksheet and answer the following questions What is the function of the muscular system? Why is it important to have a healthy muscular system? How do muscles work in pairs to make a joint move? ex. Biceps and Triceps moving the elbow
