Question 25.
Write about Physiological Factors Determining Endurance. [3]
Answer:
Endurance is another significant component of physical fitness which is determined by the following two physiological factors:
Oxygen Intake: It is the amount of oxygen which can be taken by the lungs from atmosphere. If the amount is more then it is better for achieving higher V02 max, which helps to improve aerobic capacity.

Oxygen Transport: Amount of oxygen taken into the blood from lungs has to be transported to the working muscles. This transportation depends on the amount of oxygen and the circulatory system to carry this quickly to the working muscles. The transportation of oxygenated blood depends on the capacity of the heart.

Oxygen Uptake: The amount of oxygen which can be absorbed and consumed by the working muscles from the blood is called oxygen uptake. The speed and amount of O2 consumption also depends on the number. Size and metabolic capacity of the mitochondria and fortunately these can be improved up to some extent through training.

Lactic Acid Tolerance: The ability to take to higher concentration of lactic acid is a significant factor in determining aerobic capacity. Lactic acid tolerance is important for the activities that last for 40 sec or more.

Muscle Composition: These are two types of muscle fibers such as red muscle and white muscle fiber we can call it slow muscle fiber and white muscle fiber. Slow muscle fibers are best used for aerobic activities or endurance activities. In fact the elite marathoners have been reported to have greater than 90% slow twitch fibers in muscles of the leg.

Question 26.
Discuss the effects of exercise over Muscular system. [3]
Answer:
Effects of exercise on muscular system:
Healthy and sound body: Our body becomes balanced and flexible by doing regular exercise and looks beautiful.

Proper blood circulation: The heart pumps blood easily with exercise. As a result of exercise, blood reaches every part of the body properly and adequately and the muscles of the heart begin to function orderly.

Aerobic and anaerobic endurance increases: By doing exercise, the capacity of muscles to work for longer durations without fatigue is improved.

Increase in muscle mass: Regular exercise increases the muscle mass, i.e., increase in myoglobin content of muscles, thus, controlling the weight of an individual.

Number of capillaries increases: By doing exercise, the number of functioning capillaries per muscle increases and the blood supply to the muscles, too, increases.

Question 27.
Write the types of movements in detail. [3]
Answer:
Types of Movements: There are several “types” of movement in joints that are described in anatomical terms. These are:
(1) Gliding Movement
(2) Angular Movement
(3) Rotation
(4) Circumduction

(1) Gliding Movement: It is the type of movement in which one surface moves or glides over another surface. It is the type of movement in which there is no rotation or angular movement involved. It is Common in all of the joints but it occurs in combination with the angular movements. However, in smaller joints such as hand and feet (carpal and tarsal joints), these are the only movements.

(2) Angular Movement: This type of movement occurs between the long bones causing a change.in the angle between the two bones. The angle either increases or decreases. Various angular movements are flexion, extension, abduction and adduction.

(3) Rotation: Rotation of the body parts can be towards or away from the centre of the body. It is a form of movement in which the movement of bone is around a central axis without any displacement from the axis. Internal rotation (or media rotation) refers to rotation towards the axis of the body. External rotation (or lateral rotation) refers to rotation away from the centre of the body.

(4) Circumduction: Circumduction can be described as the movement of joints in a circular motion. It is the movement which takes place between the articular cavity and the head of a bone. It can also be visualized as a circular motion of the part being moved. It is a combination of Flexion, Extension, Abduction and Adduction. It is most prominently seen at shoulder and hip joints.

Define first aid with its aims and objectives. [5]
Answer:
First Aid: First-aid is the assistance given to a person suffering a sudden injury before the final treatment. In other words it can be said that the help given by a trained or untrained person with available resources is called First Aid. Aims and objectives of first aid:

(1) To preserve life: The first aim of first aid is to preserve the life of an injured person. But there are some limitations which are necessary to understand, such as rebandage on the injury is not in the range of first aid.

(2) To reduce pain: Reducing the pain of an injured person is also an important objective of first aid. Pain is a common phenomenon in any accident This pain can be reduced with the help of first aid.

(3) Helpful in improving plight: It is necessary to keep the patient out of pain before any medical help. If there is a strong blood flow, the condition may worsen. The speed of blood flow can be reduced by keeping the person in stationary position.

(4) Prevent injury from becoming worse: First aid is helpful in the prevention of further worsening of an existing injury. If this prevention is not ensured on time, it may get more severe and complicated.

(5) Immediate medical help: Medical help is necessary in severe injury. The injured person should be taken to the hospital as soon as possible. But if the person helping him is alone, or the injured person is not in a condition to be taken to it a hospital during injury, first aid should be provided immediately, and then he/she should be taken to hospital at the earliest.

Question 37.
What do you mean by ASD? What are its causes? [5]
Answer:
Physiology: Physiology is the scientific study of functioning of living organisms. It includes how any organism, organ system, cell, organ and bio-molecule perform the chemical or physical functions. It focuses on various functions and activities of the living organisms.

Physiological factors determining strength: The various physiological factors which determine the strength of an individual are stated below:

Size of muscles: The strength is determined by the size of the muscle. Bigger and Larger muscles can produce more force. With the help of different methods of strength training, such as weight training, the size of the muscle can be increased and as a result of that, strength is improved.

Body weight: The individuals who are heavier are stronger than the individuals who are lighter. The heavier weightlifters lift heavier weight. Thus, body weight also determines the strength of an individual.

Muscle Composition: Each muscle consists of two types of muscle fibers i.e., fast twitch fibers (white fibers) and slow twitch fibers (red fibers). The percentage of fast twitch fibers and slow twitch fibers is genetically determined and cannot be changed through training. The muscle having more percentage of fast twitch fibers can produce more strength.

Intensity of the nerve impulse: A muscle is composed of a number of motor units. The total force of the muscle depends on the number of contracting motor units. The stronger nerve impulse from central nervous system excites more number of motor units. The muscle will contract more strongly, or it can be said that the muscle will produce more force or strength. So, the intensity of the nerve impulse also determines the amount of strength.

Age and gender: Gender and age also determine strength. Males tend to be more powerful than females. It is also trainable. It can be enhanced with the help of weight training, isometric and isotonic exercises, etc.
