2. Q. What is exercise Exercise is a body activity that enhances or maintains physical fitness and overall health and wellness.

3. Aerobic Exercise Anaerobic Exercise Presence of oxygen Low/Moderate intensity Long Duration e.g. Running. Jumping, Dancing Absence of oxygen High Intensity Short Duration e.g. Weight Lifting, Sprints

4. Type Of Muscle Muscle:- Muscles are  soft tissues .

5. Characteristics Of Muscle Excitability:- It is the ability of muscles to perceive stimuli and respond to them. External & internal stimuli eliciting nerve impulse and action potential. Contractility:- ability to shorten & thicken when sufficiently stimulated. Extensibility :- ability to stretch or expand. Elasticity:- ability for extension & recoil, so muscles can return to their original form and size after contraction or extension.

6. Skeletal Muscle Human body contain over 650 individual muscle anchor to skeletal Which provide pulling power These muscles constitute about 40% of our total body weight Function:- Locomotion Maintain Posture Respiration (Intercostal muscle)

7. Skeletal muscle are made up of Muscle Tissue & Connective tissue Contractile:- Develop tension in response to chemical, mechanical, electrical Non-Contractile:- Tension Develop in response to passive loading

8. Effects Of exercise On Muscular System W hen we do regular exercise, some permanent changes take place in our muscular system. These changes occur only when exercises are performed daily. If we do exercise only once, will be changes in our muscular system but only for a temporary phase. Short Term Effect Increase Muscle Temp. Increase Metabolism Increase Production Of lactic acid Increase demand for energy for muscle to work

9. Long Term Effects Change in Shape and Size of Muscle:- Through regular exercise, the shape and size of muscle is changed. In fact, cells of muscles are enlarged which change the shape and size of the muscle (Hypertrophy)

10. Formation of More Capillaries:- a number of new capillaries are formed for a better and efficient blood circulation. Muscle Remains in Tone Position:- When exercises are done on regular basis our muscles remain in toned position. Controls Extra Fat:- Exercises burn the extra calories deposited in the form of fat. Change in the Connective Tissue:- The connective tissue, which connects fibers, becomes powerful. These tissues can bear stress of strenuous activity

11. Efficiency in the Movement of Muscles :- The movement of muscles become efficient and smooth. Delays Fatigue:- The accumulation of CO2 and lactic acid becomes less in an individual who exercises regularly. Hence, fatigue can be delayed if exercises are performed daily. Increases Food Storage:- The food storing capacity is increased when regular exercises are done. This stored food can be utilized immediately wherever it is needed.

12. Body Posture Remains Correct :- By doing regular exercise, the strength of muscles increases, which in turn, keeps the body posture in correct position. Improves Reaction Time :- As a result of regular exercise, the speed of nerve impulses increases which ultimately improves the reaction time. Effects Of Exercise On Skeletal System Increased synovial fluid production:- The flexion and extension exercises stimulate the release of synovial fluid into the joint cavity Increased range of motion:- Increased synovial fluid production increases mobility within the joint

13. Increase bone density:- weight-bearing exercises, placing strain on your bones. As the response to that strain, your body produces cells called osteoblasts, which are responsible for building your bones. Stronger ligaments:- A result of a regular longtime exercise routine, stronger ligaments, more stability, and less risk of misalignment of your joint. Increase thickness of cartilage
