Tennis Elbow

image from: http://orthoinfo.aaos.org/

Tennis elbow, the most common elbow injury is the rally an inflammation of the forearm and the tendon that connects the muscles to the bone in the elbow. These muscles are used to bend the wrist backward and to turn the palm face up. When the muscles and tendon become inflamed from overuse, you feel pain on the outside of your elbow (the lateral epicondyle). The pain is worse when you try to lift things with your palm facing down, so you may have trouble picking up a  things. Tennis elbow also causes pain when you rotate your hand in a clockwise direction, as you would in using a screwdriver or in screwing in a light bulb. You also will feel pain when you shake hands or hold a racquet or golf club. The pain may become so severe that it makes combing your hair virtually impossible.

Golfers also suffer from tennis elbow, but on the non-dominant side; a right-handed golfer will feel the pain in the left elbow. Pulling the club through the swing with the left wrist causes irritation in the left elbow. So a right-handed golfer who feels pain in the right arm or wrist is doing something terribly wrong during the swing.

A tennis player most often aggravates the elbow by hitting the ball late on a backhand swing. The backhand is an  especially difficult stroke to master. When hitting the ball with your weight on your back foot, you have to compensate by mostly using your arm and hitting late causes your elbow to be bent. You end up straining the forearm muscles and tendon. You also get tennis elbow by turning your wrist to put more spin on the serve.

Once your elbow becomes inflamed, everyday activities are enough to keep it irritated. Giving up your weekly tennis game to rest your elbow is not enough to solve the problem. Treating tennis elbow requires an exercise program to increase the strength and flexibility of the forearm muscles and tendon. One they are strong enough to withstand the stress of a backhand, the pain will go away and won’t return.

MALAYSIAN XI V CHELSEA

SUMMARY
It is consecutive 1-0 wins for Chelsea in pre-season as Didier Drogba's free-kick late in the second half is decisive. It was one of those did-it-cross-the-line-moments after it first hit woodwork and the keeper, the home side believing no.

Conditions were tough due to a bumpy pitch and extreme heat but Chelsea should have had more goals. Frank Lampard and Daniel Sturridge would have scored on many days.

The home team had just two chances, both badly missed and the Chelsea defence looks good. More sustained threat at the other end needs to be found but again it was different sides each half and a different role for Yossi Benayoun. Players may have longer on the pitch in Bangkok in three days' time.

The 84,980 crowd is believed to be the biggest ever official attendance for a Chelsea friendly match although it would be surpassed by the famous Moscow Dynamo match in 1945 if those that entered Stamford Bridge without paying that day are included. Those in Kuala Lumpur make a wonderful noise.
BEST MOMENTDrogba showing he is still a solid-gold match winner by both earning and converting the set-piece that separated the sides.

TEAM NEWS Starting was an unusual front three of Fernando Torres flanked bySalomon Kalou on the left and Yossi Benayoun on the right.Florent Malouda was on the left so starting captain Frank Lampard moved to a less accustomed right berth. Josh McEachran was again the deeper of the midfield three and there was a second appearance for centre-back Slobodan Rajkovic following the Wycombe game. He was paired with Branislav Ivanovic.

The second-half side was 11 different players with young Nathaniel Chalobah partnering John Terry and Billy Clifford and Yury Zhirkov both in midfield. Didier Drogba led the line with Nicolas Anelka left and Daniel Sturridge right.

The Malaysia side was most Under 23 internationals with a few senior professionals.

FIRST HALFThe wall of sound that rose many decibels when the team came out continued as the players kicked Right to Play red footballs into the crowd.

Within the first two minutes of the game there was a link-up between Benayoun and Torres, the Spaniard shooting from just outside the penalty area but the Malaysian keeper Farizal Marlias was up to the challenge and saved.

The home side pressed forward four minutes later but Bertrand with a burst of pace dispossessed their number 9, Hairudin Omar, who scored against Chelsea in this stadium eight years ago.

Benayoun, finding space off the right wing, almost slipped the right ball through to Kalou but it was just too strong and the keeper reached it first. Bertrand showed his pace getting forward after 17 minutes and although the cross was cut out, it was then gifted to Lampard who perhaps surprised by that, stabbed his shot wide from 10 yards out.

A McEachran and Kalou combination then looked to have handed Torres a clear sight of the target but full-back Subramaniam got in a vital sliding tackle.

The atmosphere continued to be immense, the majority present supporting Chelsea. An injury midway through the half brought an impromptu drinks break on a sweltering, tropical evening. Hilariohad been a total spectator.

Malaysia did win a 25th minute corner but Malouda headed away. Three minutes later Hilario saved well with his feet but Wan Nor was offside anyway.

The Blues made what looked an unscheduled change on 38 minutes with Van Aanholt coming on for Bertrand who held the back of his thigh. It was unfortunate for the England Under 21 international who had enjoyed as many good moments in the half as anyone.

Kalou crossed too high for Lampard before the Ivorian did tee up a chance for the same player who missed for a second time in the game, this time sliding onto a square pass but turning the ball wide.

The best Chelsea spell of the first half was saved for stoppage time, Benayoun unable to convert at the far post from Bosingwa's whipped-in cross, and then Van Aanholt bombing forward and taking a return pass from the Israeli but the keeper saved the young Dutchman's shot with his feet. The man between the Malaysian posts had a good opening 45 minutes.

SECOND HALFFavourite for the first attempt on goal from an all-changed Chelsea team would not have been Mikel but the Nigerian ran onto the ball and had a very worthy dig from 30-yards that flew a foot wide.

The new 11 players then struggled to put anything else together by way of an attack until Anelka showed vision to spot Terry's run from deep from the Frenchman's position way out on the left, but the low pass didn't quite reach its target.

At the other end the new back four were looking just as solid as their predecessors with Chalobah providing calm interceptions twice in three minutes.

Finally however on 67 minutes the home team had a genuine chance. The ball was given away and was knocked in behind Terry by Irfan Fazail to Syahrul Azwari but the moment got to the substitute and he blazed over.

Chelsea set-pieces looked a promising possibility against a team almost to a man shorter than the side in blue but Terry headed a Drogba free-kick over and then did the same with a Zhirkov corner moments later. Between those Sturridge should have scored.

He was given just the service he likes by Mikel, down the channel and onto his left foot. But the keeper again proved unbeatable, his last contribution before being subbed.

The goal came on 78 minutes and the free-kick that led to it was won by the scorer, Drogba caught when surging past an opponent. From out on the left his strike was sweet and when it cannoned off the post it bounced back off the diving keeper and down onto the line with plenty of spin.

The gloved hand of the substitute pulled it out and it will need a close study of TV replays to determine whether the linesman should have given the goal.

There should have been an equaliser on 84 minutes after a clever pass between the Chelsea centre-backs but Thamil Arasu wasted it, to his and his team-mates disbelief.

Volume, Density, Torque and Impulse

Volume, Density, Torque and Impulse
A body’s volume is the amount of space that it occupies. Density
combines the mass of a body with the body volume. Density is defined
as mass per unit of volume. A rotary effect created by an eccentric force
is known as torque or moment of force. Torque, which may be thought
of as rotary force, is the angular equivalent of linear force. Impulse is
defined as product of force and the time over which the force acts.

Centre of Gravity, Weight and Pressure

Centre of Gravity, Weight and Pressure
A body’s centre of gravity, or centre of mass, is the point around which
the body’s weight is equally balanced, no matter how the body is
positioned. Weight is defined as the amount of gravitational force
exerted on a body. Pressure is defined as force distributed over a given
area.

Inertia, Mass and Force

Inertia, Mass and Force
Inertia means resistance to action or to change. Inertia is the tendency
of a body to maintain its current state of motion, whether motionless or
moving with a constant velocity. Mass is the quantity of matter
composing a body. Force can be thought of as a push or a pull on a
body. Each force is characterised by its magnitude, direction, and point
of application to a given body.
