FUN SPORT FOR THE YOUNG












Futsal is a variant of association football that is played on a smaller playing surface and mainly played indoors. Its name is derived from the Portuguese futebol de salão and the Spanish fútbol de salón (colloquially fútbol sala), which can be translated as "hall football" or "indoor football". During the sport's second world championships held in Madrid in 1985, the name fútbol de salón was used. Since then, all other names have been officially and internationally changed to futsal.


Futsal is played between two teams of five players, one of whom is the goalkeeper. Unlimited substitutes per team are permitted. Unlike some other forms of indoor football, the game is played on a hard court surface delimited by lines; walls or boards are not used. Futsal is also played with a smaller ball with less bounce than a regular football. The rules create an emphasis on improvisation, creativity and technique as well as ball control and passing in small spaces.

Futsal has become more and more popular among teenagers because the game is easy to play and doesn’t need a lot of player to play.

Bossaball for the heart




Bossaball is a sport invented in Spain by the Belgian Filip Eyckmans, who developed the concept between 2003 and 2005. It is similar to volleyball, but also includes elements of football (soccer), gymnastics and capoeira. Each side of the court has an integrated trampoline, allowing players to bounce high enough to spike the ball.


Game play
Each team consists of 3 to 5 players. One player (the attacker) is positioned in the trampoline, the others around him/her on the inflatables. A player from the serving team (the server) throws or kicks the ball into the air and attempts to hit the ball so it passes over the net on a course such that it will land in the opposing team's court (the serve). The opposing team must use a combination of no more than 8 contacts with the ball to return it to the opponent's side of the net. These contacts can be exercised using any body part (maximum 2 successive contacts with the head or feet, maximum one contact with the hands).

During a rally the ball is tossed around while the attacker jumps on the trampoline in order to gain height. The attack begins when one of the rallying players aims the ball's trajectory towards a spot in the air where the attacker can hit it (spike or kick) and returns the ball over the net.

The team with possession of the ball that is trying to attack the ball as described is said to be on offense. The team on defense attempts to prevent the attacker from directing the ball into their court: players at the net jump and reach above the top (and across the plane) of the net in order to block the attacked ball. If the ball is hit around, above, or through the block, the defensive players arranged in the rest of the court attempt to control the ball with a dig (usually a fore-arm pass of a hard-driven ball, or a foot control). After a successful dig, the team transitions to offense.

The game continues in this manner, rallying back and forth, until the ball touches the court within the scoring zones.

Scoring

When the ball contacts the floor (the bottom of the trampoline or the inflatables) within the court boundaries, the team on the opposite side of the net is awarded a score. Three points are assigned for scoring on the trampoline. One point is assigned for scoring on the inflatable cushions, except for the bossa wall which is the ring around the trampoline. When the ball touches the bossa wall the rally continues.

The team that scored serves for the next point. If the team that scored served in the previous point, the same player serves again. If the team that scored did not serve the previous point, the players of the team rotate their position on the court in a clockwise manner. The game continues, with the first team to score 25 points (and be two points ahead) awarded the set. Three sets are played in one match.

The Truth About Trans Fat....

Trans fat is the common name for unsaturated fat with trans-isomer fatty acid(s). Trans fats may be monounsaturated or polyunsaturated but never saturated.
Unsaturated fat is a fat molecule containing one or more double bonds between the carbon atoms. Since the carbons are double-bonded to each other, there are fewer bonds connected to hydrogen, so there are fewer hydrogen atoms, hence "unsaturated". Cis and trans are terms that refer to the arrangement of chains of carbon atoms across the double bond. In the cis arrangement, the chains are on the same side of the double bond, resulting in a kink. In the trans arrangement, the chains are on opposite sides of the double bond, and the chain is straight.
The process of hydrogenation adds hydrogen atoms to cis-unsaturated fats, eliminating double bonds and making them into partially or completely saturated fats. However, partial hydrogenation converts a part of cis-isomers into trans-unsaturated fats instead of hydrogenating them completely. Trans fats also occur naturally to a limited extent: Vaccenyl and conjugated linoleyl (CLA) containing trans fats occur naturally in trace amounts in meat and dairy products from ruminants, although the latter also constitutes a cis fat.
Unlike other dietary fats, trans fats are not essential, and they do not promote good health. The consumption of trans fats increases the risk of coronary heart disease by raising levels of "bad" LDL cholesterol and lowering levels of "good" HDL cholesterol. Health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts. Trans fats from partially hydrogenated oils are more harmful than naturally occurring oils.

Health risks

Coronary heart disease

The primary health risk identified for trans fat consumption is an elevated risk of coronary heart disease (CHD). A comprehensive review of studies of trans fats was published in 2006 in the New England Journal of Medicine reports a strong and reliable connection between trans fat consumption and CHD, concluding that "On a per-calorie basis, trans fats appear to increase the risk of CHD more than any other macronutrient, conferring a substantially increased risk at low levels of consumption (1 to 3% of total energy intake)". This study estimates that between 30,000 and 100,000 cardiac deaths per year in the United States are attributable to the consumption of trans fats.
