Question 23.
Participation in physical activity for a longer duration maintains functional fitness among aged population. Justify. [5]
Answer:
On the ageing process, physical activity can play very effective role, however, it should be implemented in a suitable manner. It is a well known fact that regular physical activity is the supplement to delay the ageing process. It can in some cases, overturn the most common signs of ageing viz., loss of muscles and bones, increased body fats, decline of memory, decreased metabolism, flexibility and blood flow etc. Participation in physical activity for a longer duration maintains functional fitness among aged population in following manner :

(i) Reduces loss of muscles mass : With advancing age the muscle mass decreases. The accumulation of fats reduces due to regular exercise. Ageing has a depressing consequence on metabolism. Regular physical activity results in dropping the metabolic rate and decreases the loss of lean body mass.

(ii) Maintains bone density : With advancement of age, bone density decreases as well generally leading to the rupture or osteoporosis. Physical activity assists in maintaining bone mass and prevent osteoporosis. Bone growth gets stimulated with resistance exercises.

(iii) Improves lungs capacity : Oxygen uptake and exchange increases and enhances the lungs capacity due to regular exercise. In maintenance of strong lungs, it plays prominent role and reduces the loss of elasticity of the lungs and chest wall.

(iv) Lessens stress and tension : Regular physical activity has a distinctive capability to slow down the depression process by reducing stress and tension. Actually, regular physical activity lessens the levels of body’s stress hormones like adrenaline and cortisol. The body’s natural pain killers and mood elevators like the endorphins are produced due to regular physical activity.

Question 24.
Differentiate between Intrinsic and Extrinsic motivation. Explain in detail Goal setting and Reinforcement as technique of motivation. [5]
Answer:
Goal setting : Achieving performance goals is a symbol of competency that affects motivation positively, hence it is essential to set realistic goals based on individual’s own abilities. The level of the motivation gets adversely affected when goals are set up too high or too low. The goal should be realistic, precise and within reach but should at the same time be a difficult one. Goal settings have been acknowledged as an influential motivational technique as it mobilizes an athlete’s hard work and extends his determination.

Reinforcement: Reinforcement is a vital motivation means. It refers to some kind of occurrence that increases or decreases the possibility of a similar reaction taking place in the future. Positive reinforcements enlighten the athlete at what time he is doing something accurate and support the continuance of the activity in the precise direction. Negative reinforcement is in general, of slight importance since it simply indicates that the actions are inaccurate devoid of providing information with respect to the accurate reaction or behaviour. It has been established that positive reinforcement has to a large extent, more motivational value than negative reinforcement.

Question 25.
Write in detail about the Dislocation and Fractures among the bones and joint injuries. [5] Answer:
Dislocation : It is an injury of joint in which the adjoining bones are displaced from their original position. Dislocations mainly occurs in contact sports, such as football, hockey, and in sports that may involve falls, such as downhill skiing, gymnastics, volleyball and also during a motor vehicle accidents.

Dislocation takes place in different location of the joints like :

  1. Dislocation of shoulder joint.
  2. Dislocation of lower jaw.
  3. Dislocation of hip joint.

Fracture : Bone injuries occur in the bone due to some impact or minimal trauma injury as a result of certain medical conditions that weaken the bone. There are many types of bone injuries which are as follows :

  1. Simple fracture
  2. Compound fracture
  3. Greenstick fracture
  4. Comminuted fracture
  5. Transverse fracture
  6. Oblique fracture
  7. Spiral fracture
  8. Pathologic fracture
  9. Impacted fracture
  10. Stress fracture.

Question 26.
Differentiate mechanically between walking and running. Explain in detail mechanical analysis of walking. [5]
Answer:
Walking : Walking is rolling down from heel to toe action. The first phase is heel strikes the ground followed by the transfer of weight and balance making. Afterwards the heel is rolled forward and push is given by toe and swing comes after. During walking the head should be straight without tension in shoulder. In the torso region the abdomen muscles should be slightly tightened, loose abdomen muscles cause back pain. The arm swing helps to gain speed in walking.

Running : Running is a toe action movement. For running, the focus is on the three major producing action-push off, knee-drive and paw- back. These three phases are done in a sequential maimer to provide efficient running action, push off is the primary toe action movement needed to supply the driving force in forward direction. The force comes from the powerful contraction of calf muscles by extension of ankle joint. The slight flexion of knee joint provides horizontal force instead of vertical force. Body is also bent forward.
