Question 19.
List down the nutritive components of diet and explain any one. [2]
Answer:
Nutritive components of the diet are carbohydrates, Protein, and Fat.
Protein: These are the basic structure of all living beings and the building blocks of our body. Proteins are the main components of muscles, tendons, ligaments, organs, glands, and all living body fluids. These are complex organic compounds that are formed from a chain of amino acids that contain carbon, hydrogen, and nitrogen. It is of two types:

(1) Essential proteins: There are 9 amino acids that are taken from food and they are not made in the body. The source of essential proteins are pulses, milk, dairy products, soybeans, meat egg etc. They are required for growth of tissues.

(2) Non-Essential proteins: There are more than 13 essential proteins. Body requires them in very less quantity as they help in the synthesis of essential proteins. The sources of non-essential proteins are grains, dry fruits, and vegetables.

The function of Proteins:

  • It builds muscles, tissues and organs.
  • It is essential for the growth, maintenance and repair ofall cells.
  • It produces antibodies and improves the immune system.
  • Transports the nutrients and oxygen in blood.
  • improves metabolism and digestion.

Question 26.
How is cardiovascular fitness measured with the help of the Harvard Step test’? Explain. [3]
Answer:
Harvard Step test: This test was developed by Brouha at Harvard University in 1943. It is a cardiovascular fitness test In this test the individual is required to step on and off a 20-inch high platform, 30 times a minute until exhaustion or until five minutes elapse. Through this test, we get a score that indicates the fitness of the subject. Equipment: To conduct the test following things are needed:
(1) Stair or stool 20 inches (boys) 16 inches (girls) height
(2) A stopwatch
(3) Helper
Procedure:
(1) First of, all warm up for minutes.
(2) Then step onto a standard, high box once every two seconds for 5 minutes i.e. 150 steps.
(3) The assistant stops the test after 5 minutes.
(4) The assistant measures the athlete’s heart rate (beats per minute (bpm) one minute after finishing the test (Pulse-1).
(5) The assistant measures the athlete’s heart rate (bpm) two minutes after finishing the test (Pulse-2).
(6) The assistant measures the athlete’s heart rate (bpm) three minutes after finishing the test (Pulse-3).

Assessment: Using the three pulse rates (bpm), an estimate of cardiovascular fitness can be determined as follows:
Fitness Index (short form) = (100 x test duration in seconds) divided by (5.5 x pulse count between1 and 1.5 minutes).
Redness Index (long form) = (100 x test duration in seconds) divided by (2 x sum of heartbeats in the recovery periods).

Question 27.
Define speed and explain any one method to develop it. [3]
Answer:
Speed can be developed indirectly by developing its dependent factors like flexibility, technique, explosive strength, and coordinative abilities. The training methods for speed development are:
(1) Acceleration runs
(2) Pace run

(1) Acceleration Run Method: This is the training method for developing the acceleration zone or speed-up zone in races. Acceleration is the capacity to attain maximum speed in a minimum time. In this training method, the athlete runs 20 to 30-meter distance with maximum speed to attain the top speed as fast as possible. The rest period is 2-5 minutes to provide sufficient recovery.

This training is repeated 5 to 10 times with sufficient rest period, ancient rest period, ancient rest period, ancient rest period, ancient rest period. ancient rest period. Acceleration runs should be started only after proper warming up. It is practiced 3-4 times a week. In this method, speed or intensity is kept at 90 to 100% of the total individual’s capacity. It is usually practiced when the competition is close.

Schedule:
(1) Speed or Intensity: 90 to 100 percent of best possible ability. (2) Distance or Duration of Work: 20 to 30 meters (4 to 6 seconds) (3) Number of repetitions: 5 to 10 times. (4) Recovery Period: 2 to 5 minutes (sufficient recovery), ancient recovery), ancient recovery), ancient recovery), ancient recovery). ancient recovery). ancient recovery). (5) Care: Perform proper warming-up, crouch position during start, first few steps of short distance, body bent forward.

(2) Pace Run Method: Pace is setting a stable speed which is a very important part of the race. Pace running is running the complete distance at a constant or steady pace by distributing energy evenly in a race. Pace running is used in races of 800 meters and above. If the pace is disturbed constantly then race is affected to great extent For this method, machines like treadmills can be used to provide stable pacing.

This method is practiced, when the competitions are close. In this method, the speed is kept around 60 to 90 percent of the best ability. The distance can vary from 200 to 800 meters. This method develops anaerobic endurance for a longer period, thus constant pace can be achieved. It is practiced 3 to 4 times a week.

Advantages:
(1) It improves the reaction time of the athlete, thus, the athlete takes a quick start as the race begins.
(2) It develops the capacity of the athlete to adjust his top speed.
(3) This method develops anaerobic endurance for a longer period, thus, a constant pace can be achieved.
(4) Speed development training method develops the acceleration ability thus it helps an athlete to reach maximum speed in the starting.

Discuss in detail the different types of coordinative ability. [5]
Answer:
Coordinative ability: It is the combination of body movements of several limbs or body parts combined in a manner that is well timed, smooth, and efficient with respect to the intended. These are also defined as those abilities which enable an individual to do related activities accurately and efficiently. Types of co-ordinative ability:

(1) Orientation ability: It is an ability to realize the position of the body or its parts in space and time. In other words, it is the sportsperson’s ability to analyze and change the position of the body and its parts in time and space in relation to gravity, moving objects like a ball, an opponent, a playing field, etc.

(2) Coupling ability: Coupling ability can be referred to as the ability to combine the movements of different body parts for performing perfect sports movements. Every sport requires this kind of ability, but this ability has more sig team sports, gymnastics, and combative sports. For example, in gymnastics, the movements of the hands, head, trunk, and legs are essential to be successfully combined to achieve a certain goal.

(3) Reaction ability: The ability to react instantly or quickly and effectively to a signal is called reaction ability. There are two types of reaction ability:

  • Simple Reaction Ability: The ability to react quickly in a determined manner to a well-known signal is called as simple reaction ability. For example, the reaction of a swimmer at the start of the competition is already known to him.
  • Complex Reaction Ability: The ability to react quickly to an unknown or unexpected signal is called a Complex reaction ability. These signals are unexpected because the sportsperson does not know when and to which signal he has to react For example, in football the reaction of a goalkeeper while facing ball from an opponent

(4) Balance ability: Balance ability is understood as an ability to keep the body or its parts in a relatively stable position in both static and dynamic conditions and regain balance quickly after the balance disturbing movements. This type of ability is required in almost every game and sport but it has special importance when movements are done in a small area.

(5) Rhythm ability: The ability to understand the rhythm of movement and to do the movement with the required rhythm is known as rhythm ability. In some sports like gymnastics, the athlete has to perceive an external rhythm given in the form of music and to express it in his movements. In some sports where rhythm is not given from outside, the sportsman has to make use of rhythm stored in his motor memory.

Question 35.
What are Knockout tournaments? Draw a knockout fixture for 19 teams, mentioning all the steps involved. [5]
Answer:
Knockout Tournament It is a type of elimination tournament where the loser of each match is immediately eliminated from winning the championship or first prize in the event Example: Team X and Y are to play a match against each other. Since its a knock-out tournament the team which beats the other goes further and the losing team is out of the tournament

Knockout fixture for 19 teams:
No of matches: N-l = 19-1 = 18 matches
No of rounds: 2*2×2*2×2 =(2)5= 5 rounds
A number of teams in each quarter:
\(=\frac{N}{4}=\frac{18}{4}\)
On dividing 19 by 4, since quotient = 4 and
remainder = 3
Number of teams in 1st quarter = 4 +1 = 5
Number of teams in 2nd quarter = 4 +1 = 5
Number of teams in 3rd quarter = 4 + 1 = 5
Number of teams in 4th quarter = 4
Total Byes: Highest power of two – No of teams
= 32-19 = 13 byes
Byes in Upper half \(\frac{\mathrm{Nb}-1}{2}=\frac{13-1}{2}\) = 6 byes

Byes in Lower half \(\frac{\mathrm{Nb}+1}{2}=\frac{13+1}{2}\) = 7 byes

Question 37.
What are the effects of exercising on the cardio-respiratory system? Explain. [5]
Answer:
After performing exercise for the long term, certain adaptations take place in our cardiovascular system. These are called the long-term effects of exercise. The various long-term effects of exercise are stated below;

(1) Increase in the size of the heart; When you perform the regular exercise the muscles of the heart increase in size and strength. In fact, the left ventricle adapts to the greatest extent. The walls of the heart grow stronger and thicker.

(2) Decrease in resting heart rate: Regular exercise decreases the resting heart rate. Eventually, the heart becomes more efficient and no longer needs to beat as Physical 26 Education Class XII quickly supplies the body with blood while at rest

(3) Increase of stroke volume in rest The resting heart rate is able to slow down because the heart is now trained to pump a larger quantity of blood every beat.

(4) Decrease of blood pressure: Regular exercise decreases blood pressure. Thus, it decreases the chances of hypertension and other diseases due to an increase in blood pressure.

(5) Increase in blood volume: During heavy exercises, the body produces a greater number of red blood cells to keep the muscles supplied with oxygen. In fact, there is an increase in plasma volume which enhances the blood volume.

(6) Quicker recovery rate: Regular exercise quickens the recovery rate. A trained athlete’s heart rate becomes normal earlier in comparison to a beginner’s. So, the recovery becomes fast

(7) Reduced risk of heart diseases: Regular exercise gradually reduces stress-related hormones from circulating in the blood. This increases the blood vessel path, which in turn lowers the risk for the buildup of plaque that can lead to coronary heart diseases. Hence, exercises reduce the risk of heart disease.
