Exercise is helpful in preventing sugar from accumulating in the blood by triggering muscles to receive more glucose from blood and utilize it for energy.

(iv) Exercise helps in motor development :
Exercise helps in increasing the motor development of infants and children at a very rapid pace which in due course improves in building fine movements later on in life. The movements of muscles become efficient and smooth by doing exercise in premature age; their movements turn out to be attractive.

The walls of the heart develop into stronger and thicker as shown in recent studies and the thickness of myocardial wall increases as well.

(ii) Resting heart rate decreases : The resting heart rate decreases due to regular exercises. After duration of 10 week training programme, the resting heart rate may reduce up to 10 beats per minute from the normal of 72 beats per minute. The heart becomes more efficient due to regular exercises. In highly conditioned athletes the resting heart rate decreases to 30 beats/minute.

(iii) Stroke volume increases at resting conditions : The stroke volume increases at resting conditions due to regular exercises. The stroke volume at rest remains up to 50-70 ml/beat in untrained individuals; in trained individuals it ranges from-70-90 ml/beat and in the elite endurance athletes it ranges from 90-110 ml/beat.

Question 18.

Angular motion is rotatory motion, it occurs when all points on a body or object move in a circular path about the same fixed central line or axis. A child swings and rotations in hammer throw are the best example.

Question 19.
What do you understand by relative strength?
Explain the importance of body weight in determining relative strength. [3]
Answer:
Relative strength is strength in relation to your body weight. Relative strength have a determining importance in sports in which the athlete shifts his body in space without any additional external weight (H/J and L/J) as well as in sports in which he has to restrict his own weight within the framework of weight division (e. g. boxing, wrestling, weight lifting etc.) e.g. if 1 RM (repetition maximum) is 50 kgs and body wt. is 50 kg and if 1 RM is 70 kg and body wt. is 50 kg, in second category the relative strength is more.

Question 24.
What is movement speed? Explain the methods to develop speed endurance. [5]
Answer:
Movement speed is the time taken between the initiation of movement and the completion of the movement. It depends upon techniques, explosive strength, flexibility and coordinative abilities. It plays a vital role in boxing, gymnastics, swimming; throws and jumps etc. where the minimum time is taken to complete the movement.

To develop the speed endurance we will have to work more on pace races because pace races means running the whole distance at a constant speed. Generally, 800 meters and above races are included in pace races. As a matter of fact, an athlete can run a distance of 300 meters at full speed but, in longer races such as 800 meters or above races he must conserve his energy by reducing his speed. For example, if there is a runner of 800 meter race his best time is 1 minute 40 second, so, he should run first 400 m in 49 seconds and next 400m in 51 seconds.
