flexibility and discuss the effect of ageing in flexibility 3
Ans. Flexibility is the range of
movements of joints. An individual, who has proper flexibility, can perform his

Q19. State
any two factors which affect the projectile trajectory.
Ans. 1. Any object when projected
at different angles covers different distances. When it is projected or
released at the angle of 30° making a parabolic path, it covers less distance i.e.,
AB. When it is projected at the angle of 60°, it covers, a distance i.e., AC
and when it is release at the angle of 45° making a parabolic path it covers
the maximum distance i.e., AD. Here it is supposed that the initial velocity in
all the cases is same.
2. The distance covered by an object depends on
the initial velocity of the projectile. If the initial velocity is more, the
object covers maximum distance. On the other hand, if initial velocity is less,
the object covers less distance.
Q20. Elucidate
in detail about the Intramurals and extramural. 5
Ans. Intramurals: This means that the activities which are performed or conducted
within the walls or within the campus of an institution. Intramurals are

The following precaution should be taken while
taking food supplements:
1. First of all ensure that there is a lack of
essential nutrients in a child. So consult the doctor whether the child needs
to take food supplements or not.
2. Before purchasing an individual should
ensure that it is free from preservatives, contains no fillers and does not
contain any added sugar.
3. Food supplements may create harm if they are
taken in excessive dosage specially the minerals and fat soluble vitamins which
can be accumulated in the body. Some of the food supplements may cause harm due
to their rapid absorption in a short period of time.
4. Don’t pay heed to the words of salesmen or
advertisement which claim that these supplements will improve Childs brain.
Q22. What
is the impact of surface and environment on the athlete/ player. 5
Ans. The surfaces on which
athletes run, play a large role in determining how well they perform and how
likely they are to get injured. To understand why this is so, it is important
to realize that running is essentially a series of collisions between your body
and the ground. There are different kinds of surfaces on which we play sports,
e.g. natural grass, wooden flooring, synthetic surfaces for sport and
recreational visage.
Playing surfaces also play an important role to
avoid sports injuries when the friction is optimum and the hardness of the
surface is according to the game. The chances to get injures are very less.
Playing surfaces also increase the life of ankle and knee by providing proper
shock absorber between the body and surface of playing.
Impact
of Environment: Environmental
conditions involve one or more different circumstances, as a condition to be
faced in regular training or as an anticipated condition that will be
encountered at a future time. Environmental conditions include warm weather,
cold weather, high altitude, rugged topography, man-made impacts on air
quality, wind speed, rain, time zone changes, indoor atmospheric conditions,
and crowd noise. Warm weather, which is often accompanied by high humidity, is
likely the most common adverse environmental factor encountered by athletes.
Warm weather and humidity are also readily adapted to through a gradual
introduction of the body to the unaccustomed heat, through both day-to-day
living in the warmer conditions as well as training.
Q23. Explain
the term ‘stress’. How can it be managed? 5
Ans. Stress consists of bodily
changes produced by physiological or psychological conditions that tend to
upset the homeostatic balance. In medical language ‘stress’ is defined as a
perturbation of the body’s homeostasis. It can be managed in the following way:
1. The individual who is under
stress, should try to build up self-confidence. He should have enough
confidence to deal with the stress.
2. Developing various type of
hobbies, such as gardening, TV matching, swimming, listening to music is also
significant for reducing stress.
3. One should try to stay cool
and confident when there is stress. Remaining in such a state can be helpful in
reducing stress.
4. Stressed persons usually remain
busy in talking about their own stress. They become pessimistic. You can be
affected by their views. So, always avoid such people who remain under stress.
Q24. Elucidate
any 5 physiological changes due to ageing process. 5
Ans.
1. Changes in metabolism and body composition: With advancement of age our
body needs less energy and the metabolism slows down. Consequently there is an
increase in the accumulation of body, fat and lean body weight (bones,
ligaments, tissues, tendons, muscles and water) decreases. The metabolic rate
decreases gradually with the increasing age. It also results in more
accumulation of body fat.
2.
Changes in nervous system: A number of research studies indicate that reaction time and
moment time slow down with increasing age. Their brain’s weight, the size of
its network and its blood flow decreases with the age. However, the brain
adopts to these changes growing new patterns of nerve endings. To recall
memories becomes slow.
3.
Changes in the gastrointestinal system: With increasing age, there is a reduction in
the production of hydrochloric acid, digestive enzymes and saliva. These
changes may result in delayed emptying of stomach, impaired swallowing. The
breakdown and absorption of foods may also be impaired. The liver becomes less
efficient in metabolizing drugs and repairing damaged liver cells.
4.
Changes in urinary system: As the age, the mass of the kidneys decreases. This leads to
reduction in the rate of blood filtration by the kidneys. The capacity of bladder
decreases and there is an increase in residual urine. These changes increase
the changes of urinary infection.
5.
Changes in flexibility: The elasticity of tendons, ligaments and joint capsules is
decreased with ageing. The elderly persons lose 8- 10 cm of lower back and hip
flexibility according to a research study. The range of movement is restricted
as the age increases.
Q25. How
can you improve body image and self-esteem? 5
Ans. Body image is based on your
thoughts and feelings about the way your body looks. Self-esteem relates to how
much you like yourself, and how you recognize or appreciate your individual
character, qualities, skills, and accomplishments. Body image and self-esteem
can be improved by following ways:
(a) Focusing on the good things you do.
(b) Focusing on your education.
(c) Participating in a variety of sports or
activities.

(b) Before starting for the camping site, go
through the weather forecast for the area. At the camp site, watch the sky for
changes.
(c) Reach the camp site with enough time to
check the complete site during day time.
(d) Avoid areas of natural hazards for camping.
(e) Keep fuel burning appliances like stoves
far away from tents.
(f) Do not use candles or an open flame; instead,
use a flashlight inside the tents.
(g) Do not leave waste products in an open
area, but recycle them or bury them.
(h) Beware when encountering wildlife.
(i) Ensure to extinguish completely all fires
after use; do not leave any smouldering embers.
