Ans. 1, Muscle size: Bigger and larger muscles can produce more, , Q.2., , Ans., , force. Males have larger muscles than females so the size, muscles and strong can be improved with the help of weight, training., , Body weight: The individuals who are heavier are stronger, then the individuals who are lighter for example the heavier, weight lifters than the Gymnastic or other games players., , Muscle composition: The muscels which have more, percentage of fast twitch fibers can produce more strength, while the slow twitch fibers are not capable to contract faster, but they are capable to contract for a longer duration. The, percentage of fast twitch fibers and slow twich fibers is, genetically determined and can not be changed through, training., , Intensity of the never Impulse: When a stronger nerve, impulse from central nervous system excite more number of, motor units, the muscels will contract more strongly or it can, side that the muscle will produce more force or strength., , Discuss the physiological factors, determine the endurance, as a component of physical fitness: (Any three), , Aerobic capacity:, , * oxygen intake, , * oxygen uptake, , * oxygen transport, * — Energy Reserve, , Anaerobic capacity :, , Storage in body of ATP and CP (phosphogen stock), Buffer capacity - in muscles lactic acid accumlation ineffective, Endurance of lactic acid

- VO, max. This is the quantity of oxygen, which active muscles, use during exercise in one minute., , Long Answer Type Question (5 Marks), , Q.1 Discuss how physiological factors determine flexbility? 1 x 5, , Ans. 1., , Muscle strength :- The muscle should have minimum, level of strength to make the movement, specially against, the gravity or external force., , Joint structure :- There are different types of joint in, human body, some of the joints intrinsically have greater, range of motion than others. For example. The ball and, socket joint of the shoulder has the greatest range of, motion in comparison to the knee joint., , Internal environment :- Internal environment of athlete, influences the flexibility. For example-warm bath increases, body temperature and flexibility whereas 10 minutes, outside stay in 10°c temperature reduces the body, temperature and flexibility., , Injury :- Injuries to connecting tissues and muscles can, lead to thickening or fibrocin on the effected area., Fibrous tissues are less elastic and can lead to limb, shortening and lead to reduce flexibility., , Age and gender :- Flexbility decreases with the, advancement of age. However it is trainable. It can be, enhanced with the help of training, as strength and, endurance are enhanced. Gender also determine the, flexibility. Females tend to be more flexible than male., , Active and sedentary life style :- Regular activities, enhance the flexibility, whereas inactive individual looses, flexibility due to the soft tissues and joints shrinking and, loosing extensibility.

7., , Heredity :- Bony structures of joints length and flexibilities, of the joint capsules and surrounding ligaments are, genetical and can be altered by stretching programs., , (Explain any 5 points), , Q.2. Describe the physiological factor determine the speed? 1x5, , Ans., , 1., , Explosive strength- For every quick and explosive, movement, explosive strength is indispensable. Like, a, quick punch in boxing can not be delivered if the boxer, lacks explosive strength. Explosive strength further, depends on muscle composition, muscle size, and muscle, coordination., , Muscle composition- The muscle which have more fast, twitst fibers. They can do more speed. The muscle, composition is gentically determined. We will improve it, only by some training methods., , Mobility of nervous system- Motor and sensory nevers, of nervous system can be determined by the mobility of, nervous system. By training only we can limited extent in, the mobility of nervous system because speed is, determined to a great extent by genetic factors., , Elasticity and Relexing capacity of muscle- Through, the elasticity of muscle, muscle can move to a maximum, range which reduces the inner hurdles and is instrumental, in speeding up the activity. The muscles which get relaxed, soon, they contract easily., , Bio-chemical Reserves and Metabolic Power- For, doing the exercises which are done quickly muscles need, more energy. This energy in our muscles is obtained, through the prensence of phosphosen (ATP) and creating, phosphate (CP). The percentage of power and quantity, in ATP and CP can be increased through training.
