1 ) According to American Heritage dictionary “ A tournament is a series of contests in some sport or game in which a number of people or teams take part, trying to win the championship.”

2) Tournaments can be divided into two main categories –a)knockout and b)league. In K.O tournaments a team/player has to win all its matches to become a champion. Therefore a team/player is eliminated as and when they loose a match. On the other hand in a league tournament each team will get a chance to play against each other at least once. In this format result is not mandatory that is a match can end in a draw. So it is not mandatory for a team to win all the matches to become a champion and even if someone looses a match they are not out of the tournament. Apart from this categories there are some tournaments which are played on league cum knockout or knock out cum league basis.

EXAMPLES:

League : EPL/ I LEAGUE/ LA LIGA etc.

Knockout: WIMBLEDON TENNIS CHAMPIONSHIP/ FRENCH OPEN/ F.A CUP etc.

League cum knock out: ISL/ FOOTBALL WORLD CUP/ WORLD CUP CRICKET etc.

Knockout cum league: Qualifying stage of a tournament followed by the main tournament etc.

( Refer to google to checkout the above mentioned tournament).

N.B- league cum knock out and knockout cum league tournaments are also known as COMBINATION TOURNAMENTS.

BYE AND METHODS OF FIXING BYE

3) A single-elimination, knockout, or sudden death tournament is a type of elimination tournament where the loser of each match is immediately eliminated from the tournament. Each winner will play another in the next round, until the final match-up, whose winner becomes the tournament champion.

Drawing fixture for a knock out tournament:

STEP 1- TOTAL NO. OF TEAMS=N & TOTAL NO. OF MATCHES=N-1

STEP 2-THEY WILL BE DIVIDED INTO 2HALVES:

· UPPER HALF=N+1/2

· LOWER HALF=N-1/2`

STEP 3- FIND OUT THE NO. OF TEAMS GETTING BYE [ONLY IF ‘N’ IS NOT EQUIVALENT TO POWER OF 2( i.e-2x2=4x2=8x2=16x2=32……..) and not only an even number.

THEREFORE NO. OF BYES=[NEXT POWER OF 2 OF ‘N’-N]

STEP 4- NO. OF BYES IN UPPER HALF WILL BE= NO. OF BYES -1/2

NO. OF BYES IN LOWER HALF WILL BE= NO. OF BYES +1/2

EXAMPLE:

IF, TOTAL NO. OF TEAM = 11

STEP 1-THEREFORE N=11, TOTAL NO. OF MATCHES=11-1=10

STEP 2-U.H=(11+1)/2=6

L.H=(11-1)/2=5

STEP 3- THEN NUMBER OF BYES TO BE GIVEN WILL BE =16-11=5 AS 16 IS THE NEXT POWER OF TWO OF 11(i.e-2x2=4, 4x2=8 and 8x2=16)

STEP 4- NO. OF BYES IN U.H= [5-1]/2=2

NO. OF BYES IN U.H= [5+1]/2=3

4)Advantages of Knock-out Tournament:

· The knock-out tournaments are less expensive because the team, which gets defeated, is eliminated from the competition.

· The knock-out tournament is helpful in enhancing the standard of sports, because each team tries to present the best performance to avoid the defeat.

· Owing to less number of matches, it requires less time to complete the tournament.

· Minimum number of officials are required in organizing such type of tournaments.

Disadvantages of Knock-out Tournament:

· There may be many chances of elimination of good teams in 1st or 2nd round. So, good teams may not reach into the final round.

· There are maximum chances of weak teams to enter into the final round.

· Spectators may not have enough interest in the final match.

5) A seed is a competitor or team in a sport or other tournament who is given a preliminary ranking for the purposes of the draw. Players/teams are "planted" into the bracket in a manner that is typically intended so that the best do not meet until later in the competition.

Seeding is a procedure by which good teams are placed in fixtures in such a way that stronger teams do not meet each other at the very start of a tournament. In seeding, the strong teams are selected to keep them at appropriate places in the fixtures so that they should not meet in the earlier rounds.

Seeding can be done only if the standards of teams are known before the tournament. Special Seeding. That means seeding is given based on previous performance or current ranking. In this form of fixtures the seeded players are brought straight away to quarterfinals or semifinals. Though the method is unfair yet the outstanding players can't stay for a longer period at a particular place.

6) Bye is a dummy(contestant/team) that does not play the 1^st round. It is a sort of privilege to a team. Arranging pairs is very simple, when the number of entries is a power of two such as 2,4,8,16,32….etc, and when number of participants in a tournament is not a power of two but 3,5,6,7,9,10,11,12…..etc, the byes are to be given.The contestant getting bye does not play in the 1^st round. This makes the number of participants in the succeeding (Second) round even and power of two such as 2,4,8,16,32…..etc.

N.B- THE NUMBER OF BYES IS THE NEXT HIGHEST POWER OF TWO MINUS NUMBER OF ENTRIES.

EXAMPLE: IF THE NUMBER OF TEAMS (N)=11

THEN NUMBER OF BYES TO BE GIVEN WILL BE =16-11=5 AS 16 IS THE NEXT POWER OF TWO OF 11(i.e-2x2=4, 4x2=8 and 8x2=16)

Method of Fixing Byes:

· First bye is given to the last team of lower half.

· Second bye is given to the first team of upper half.

· Third bye is given to the first team of lower half.

· Fourth bye is given to the last team of upper half.

· And so on.

LEAGUE TOURNAMENT
ADVANTAGES AND DISADVANTAGES OF LEAGUE TOURNAMENTS

7) League Tournaments: These are also called round robin tournament. In a league tournament, the teams/players are treated at par. Whether the team/player wins a match or loses, the team will get a chance to play with every other team.

Examples: EPL/ LA LIGA/ BUNDESLIGA/ I .LEAGUE etc.

8) Advantages of league tournament----

➡It decides the true winner.

➡Every team will get full opportunity to show its efficiency or performance.

➡It helps in ranking all the teams.

➡Sports and games can be made popular through league tournament owing maximum number of matches.

➡A team need not wait for the competition of the other round as in single knock out tournament.

➡Appropriate opportunities are available to the players and teams to improve their performance.

Disadvantages of league tournament----

➡It requires more time.

➡It is expensive.

➡It requires more arrangement for sport officials and teams.

➡There is no provision of seeding for outstanding teams.

➡Teams that gets defeated often will lose interest in the game and that particular match become boring for the participants, spectators and even for official.

PLANNING OF LEAGUE- SINGLE LEAGUE-DOUBLE LEAGUE

(a) Single league tournament: n(n-1)/2= No. of matches.

Each team wil play against each other once. There are three methods of drawing fixture in this category:

· CYCLIC

· STEP

· TABULAR

(b) Double league tournament: n( n - 1) = No. of matches.

Such kind of tournament produces a true winner.

Fixture for seven teams using round robin method.

Number of teams (n) = 7. Rounds = n = 7. Matches = 7(7-1)/2 = 21

DATE-6.05.2020------RESPIRATORY SYSTEM

MEANING OF RESPIRATION:The system in which human being inhale oxygen and exhale carbon dioxide is known as human respiratory system.The human respiratory system is composed of various organs which play a vital role in the process of respiration.

PATHWAY OF AIR INTO THE BODY:Air travels from the external environment through various respiratory organs which are called the pathways of air into the body.These organs are stated below:

1)NOSE:The nose is a special organ to detect odours.It has a significant role in respiration.It consist of two parts- the external feature and the internal cavities or nasal cavities.

a) EXTERNAL FEATURE: The external feature of the nose is composed of a triangular frame work of the bones and cartilage covered by skin.In the inner side of the nose, there are two oval shaped openings called nostrils.

b) INTERNAL FEATURE: There are two nasal cavities or nasal passages.Then inside divided chamber has guarded with hairs that block the inhalation of large particles.

2) PHARYNX: The pharynx or throat is a funnel shaped tube that connects our nasal and oral cavities to our larynx.After the nasal cavities air passes through pharynx.

3) LARYNX: After larynx air passes through larynx or voice box.It is composed mainly of cartilage.It consist of two parts of membrane.Air causes the vocal cord to vibrate, which help to produce sound.

4)TRACHEA: After larynx air passes into the trachea that is also named as windpipe.The trachea is a tube with cylinder shaped.Length is 11.2 cm and diameter is 2 to 2.5 cm.It lies in front of osephagus and extended from larynx.Then it is divided into two bronchi

one for each lungs.The walls of trachea is made up of hyaline cartilage on the mouth of trachea there is a valve called epiglottis.It prevents food from entering into trachea.

5) BRONCHI: There are two bronchi that branch of from the trachea, these structure referred to as the right and left primary bronchi.The primary bronchi branch of into bronchial tree where air passes through the secondary bronchi which enter the lobes with the lungs.After that air reaches refinery bronchi which are further small pathways.

6) BRONCHIOLES: Bronchioles are the finest conducting pathways in the respiratory system.These bronchioles are the last pathways for air before it reaches the alveoli,where it is combined with blood from here blood is first

pumped back to the heart after that oxygenated blood is circulated through out the body.

7) LUNGS: There are two lungs in human body.Lungs are the vital organ for respiration.These are cone shaped organs, with the apex above.The base of the lungs lies resting on the floor of the thoracic cavity,the diaphragm and the lungs are divided into lobes by tissue.The left lungs has two lobes and right has three lobes.The exchange of oxygen and carbon dioxide between blood and air occur through the walls of alveoli.There are approximately 300 million alveoli in each lung.

8) DIAPHRAGM:The diaphragm is the primary muscle used in the process inspiration.It is dome shaped,a sheet of muscle that is inserted into the lower ribs.It performs an important function in respiration.As the diaphragm contracts the volume of the thoracic cavity increases and air is drawn into the lung.

9) ALVEOLI: The alveoli are the areas where oxygen is transferred into the blood in exchange of carbon dioxide.It means the gas exchange is taken place in alveoli. The air passes through the alveolar ducts into the alveolar sac where it is met with capillary networks.Air diffused into the blood through various chemical reaction.
