Learn More About Human Muscles

By Allan Thomas

The human body contains more than 600 muscles. Skeletal muscle contains contractile units that have the ability to convert chemical energy into mechanical energy, thus enabling the muscle to contract or shorten. Muscles cannot independently lengthen. They can lengthen only by contracting the opposing muscles. When one muscle (the agonists) contracts, the opposite muscle (the antagonist) lengthens.

In order for muscles to contract at all, they must be attached to the bones. Strong, fibrous tissues located at each end of the muscle, called tendons, accomplish this. The attachment of the muscle at the proximal end of the bone (the end closer to the body) is considered the muscles’ origin. The attachment at the distal end of the bone (the end farther from the body) is referred to as the muscle’s insertion. The origin of the trunk muscles are always at the upper or superior attachment, while the insertion is found at the lower or inferior attachment.

Muscles have different contraction capacities and therefore can play different roles depending on the desired movement. A muscle can contract concentrically while it shortens or pulls. This typically results in a movement in which the muscles acts as a primary mover.

A muscle can also contract concentrically in cooperation with other muscles. The synergistic effort results in a movement that the muscle would not have been able to perform completely on its own. In this situation, the muscle would be considered a synergist or an assistor.

On the other hand, a muscle may also contract eccentrically while it lengthens, Even though it is elongating, the muscle can still be contracting enough to help slow the movement. In this case, the muscle acts like a brake to control the body as it moves.

Yet another possibility is that a muscle could be contracting isometrically while it neither shortens nor lengthens. A muscle may utilize varying degrees of these isometric contractions in order to stabilize the body and certain joints during an exercise. The muscle would be working as a stabilizer in this situation.

A muscle may also contract to prevent an undesired effect of another contracting muscle. It would then be acting as a neutralizer. For example, the abdominal muscles neutralize part of the effects of the hip extensors and erector spinae as we walk. Neutralization prevents the spine from reaching large degrees of hyperextension.

As you learn the various movements the human body is capable of performing, the roles and responsibilities of each muscle during each joint motion will become clearer. If you are a personal trainer, fitness instructor, or coach, it is extremely important that you know this information in order to more competently teach and train your clients and athletes.

A compilation of brief news reports for Friday, March 2, 2007.

United States fast-food chain Popeyes Chicken and Biscuits has filed a $20 million dollar lawsuit against competitor Church’s Chicken.

Popeyes Chicken says fast-food chain Church’s Chicken was trying to steal customers.

AFC owned both companies for 12 years, till it sold Church’s in 2004. AFC claims that Church bought all 10 Popeyes restaurants owned by franchisee CVI. Popeyes Chicken says the sale of the 10 restaurants violated its franchise agreement with CVI.

The sudden buy-out in December 2006 led the restaurants to close in early January 2007.

“What Church’s chose to do, I do believe, was not honest competition,” said Ken Keymer, CEO of AFC Enterprises Inc., the parent company of Popeyes.

Church’s spokesperson chose not to comment on the issue.

The national body for scientific research in Australia, the CSIRO has announced that 93 species of shrubs and small trees of the w:genus Dryandra have been been merged into the genus Banksia in the series Dryandra. This increased the number of Banksia species from 80 to 173.

The plants are endemic to the southwestern corner of Western Australia and the former genus was named in honour of the Swedish botanist Jonas C. Dryander.

More On Science Of Chelation Therapy

Submitted by: Dr. Conrad Maulfair

The chemistry behind chelation therapy was not invented; it was discovered. The Swiss Nobel Laureate Alfred Werner in 1893 suggested the chemical structure that was later confirmed by others. This chemical structure which involves an organic molecule surrounding a metal ion was defined and termed “chelation” in 1920 and in 1913 the Nobel Prize was awarded for discovery of chelation chemistry.

The complex, of the organic molecule, when it surrounds a metal nullifies the reactive charge on the metal which is what causes certain metals to have undesirable reactions. Again, this chelation complex was not invented in a laboratory; it was discovered as existing in nature. It is a part of nature and it is a part of us. Examples of chelation chemistry existing in nature include chlorophyll which is a chelate of magnesium, hemoglobin which is a chelate of iron, vitamin B12 which is a chelate of cobalt. The coenzyme, cytochrome C, and the enzymes, catalase and peroxidase, are chelates of iron.

Chelation therapy as a medical treatment, in part, is the use of a chelating agent (organic molecule) introduced into the body, ideally as an infusion (intravenously). As it circulates around the body, suspended in the bloodstream, it will attract and surround a metal ion. The resulting complex, chelating agent (organic molecule) and the surrounded metal ion will eventually pass through the kidneys. The kidneys recognize this complex as not being food and not needed or wanted and it is filtered from the bloodstream through the kidneys into the urine and then eliminated from the body. More in a moment about why the activity of deburdening the body of minerals and metals can be so therapeutic.

[youtube]http://www.youtube.com/watch?v=LEoXzH6_WH0[/youtube]

The consideration of using this chelation chemistry therapeutically in man began to be formulated in the era around World War II as an antidote for arsenic-containing poison gasses. Arsenic is a metal, that if immobilized, would decrease the effectiveness of the poison gasses. Around the same time, the chelating agent EDTA (ethylenediamine tetra-acetate acid) appeared on the scene in 1947. Studies were done in Georgetown University and at Walter Reed Army Hospital on patients utilizing the chelating agent EDTA. An entirely different application of chelation therapy in vascular disease and related disorders began to be reported in the medical literature around 1950. Back to minerals and why they are so important in health and in disease.

Energy production is the most basic and essential activity in the body. Impaired energy production will result in impaired health and is a major factor in the development of chronic degenerative diseases and the aging process as well. The body’s energy is a composite of cellular energy production. An average body has approximately 7,000 billion cells. In order for cellular energy to proceed effectively and efficiently, enzymes must be present. Enzymes are proteins which accelerate the cellular chemical reactions that result in the cellular energy production. There are hundreds of enzymes. This enzymatic reaction must have a coenzyme or cofactor to have an effective reaction. Many coenzymes must have a mineral and/or a vitamin as an essential ingredient. Magnesium and zinc, for instance, are coenzymes necessary for hundreds of cellular chemical reactions, so .if there is a deficiency of an essential coenzyme mineral it blocks the enzyme needed to insure that the cellular chemical reaction happens and that determines the cellular function, and consequently the health and function of the organ and other systems the malfunctioning cells are located in.

There is yet another way in which minerals affect health. We have just learned of the essential nature of certain minerals in cellular health and therefore, body health. Energy production of all kinds depends on this activity. Toxic minerals can compete for positions with the enzymes. Toxic metals such as lead, arsenic, cadmium, mercury, uranium and others are particularly adroit at replacing the essential mineral (magnesium, zinc and others) on the cellular receptors. This toxic mineral (wrong coenzyme/cofactor) prevents the enzyme from being active; therefore, the cell energy and function suffers and the body’s health and function suffer, disease ensues and symptoms eventually follow and resulting symptoms are the central concern of standard medical treatment.

A chelation therapy program, as one of its modes of action, provides a solution for mineral imbalances, both essential and toxic, increasing the essential minerals and decreasing the toxic minerals and metals. A chelation therapy program is a common sense comprehensive program that when properly designed and followed can restore health, cellular health resulting in increased energy and bodily health.

Deaths on South African roads at 1215 for December 2005

Thursday, January 5, 2006

According to the South African government’s Department of Transport, the number of fatalities on the country’s roads during December 2005 was 1,215. This is compared with 1,234 the previous year, where the total number of deaths in traffic accidents was 10,530.

Department of Transport spokeswoman, Collen Msibi, stated that 512 of the fatalities were pedestrians, 414 passengers, and 289 drivers. 2005 saw the number of vehicles on South Africa’s roads rise by nearly half a million to just under eight million with 779,000 new drivers adding to the dangers on the country’s roads.

“To deal with this high level of unsafety, traffic authorities will increase the number of patrol vehicles on the road, law enforcement officers and unmarked vehicles to do more spot checks and roadblocks,” Msibi said.

“Our analysis has revealed that most accidents are preceded by offences such as ignoring road signs, driving drunk, speeding, vehicles cutting in front of others, driving defective vehicles and fatigue.”

The road toll in South Africa is similar to that of South Korea, Mexico, Japan and Thailand. However, except for South Korea these countries have significantly larger populations.

The worst country in the world for deaths in road traffic accidents, is currently accepted to be China. Figures released for 2002 reveal that 250,007 people were killed in that year.

The South African government has acknowledged the problem since 2001. At that time they launched their “Arrive Alive” campaign, targeting vehicle condition, driver fitness, speeding and drunk driving.

British Prime Minister Tony Blair suffers defeat in vote on terror laws

Wednesday, November 9, 2005British Prime Minister, Tony Blair, has suffered what some consider a humiliating political defeat after the House of Commons dismissed a controversial government proposal to permit the detention of terror suspects for up to 90 days without bringing charges. Under current UK anti-terrorism laws, suspects can be held for up to 14 days without any charges being made against them.

Members of Mr Blair’s Labour Party used the vote to rebel against the proposal, with a crucial 49 tipping the balance to reject it by 322 votes to 291. It was the first Commons defeat for Mr Blair in his 8 years as Prime Minister. Later, a second proposal to extend the detention time limit for terror suspects to 28 days was passed by 323 votes to 290.

The police called for new powers after the bomb attacks in London on July 7, 2005. They argued that because anti-terrorist investigations can take considerable time, the new powers would have been justified. Critics are sceptical of these claims. Opponents believe that by effectively giving the government the right to imprison for up to three months anyone who it alleged to have been involved in terrorism, without having to present any charges in court to justify the detention, the bill could have led to abuses of power.

Leaders of the opposition parties were delighted with the results. Conservative leader Michael Howard said the vote had “diminished” the Prime Minister’s authority and that he should tender his resignation. Charles Kennedy, leader of the Liberal Democrats, called Mr Blair a “lame duck”.

Speaking after the result of the vote was announced, Mr Blair accused those who’d opposed the measure of being “out of touch”, talking of a “worrying gap between parts of Parliament and the reality of the terrorist threat and public opinion”.

Former Conservative ministers Peter Lilley and Stephen Dorrell criticised the government for using senior police officers to lobby MPs over the vote. They characterised this as the “politicisation of the police”.

How Can I Build Muscle Mass And Lose Weight At The Same Time?

By Chris Chew

As a fitness personal trainer and weight loss consultant, I am often asked this question,”Can I lose weight and build muscle size at the same time?”

Now let me ask you a question. If you are building muscle mass, then you are building body tissues and since muscles are dense body tissues, they are heavy. That being the case, when building muscles, you must be gaining and not losing weight right?

What these folks actually meant was that whether they can lose body fat and build muscle mass at the same time. Yes, it is possible to lose fat and build muscles at the same time. However, the process can be rather complicated and it takes alot of discpline and knowledge to do that. Furthermore, results may be even slower than the conventional 2 steps bulking up and cutting down phase method.

[youtube]http://www.youtube.com/watch?v=IY2bgadHh-c[/youtube]

You see, losing fat and gaining muscles are at odds with each other. This is because to lose body fat weight, you have to eat less calories than the energy your body used up in your daily activities. On the other hand, to gain muscles you have to eat more calories than your body used as its energy source. So they are contradictoins.So how to achieve the desired result simultaneously?

Well, as I said, it can be done but is quite complicated. This is the reason why most professional bodybuilders train in 2 phases. The bulking up phase and the cutting down phase.

The bulking up phase is when the bodybuilders train to put on muscle mass and don’t even think of losing fat. In this process, they will actually be putting on alot of weight. They will put on muscle weight as as well as some weight from body fat because they have to eat alot to put on huge muscle mass.

When these bodybuilders put on enough muscles, they will then begin the cutting phase. It will also be alot easier to lose fat now because all the muscles they put on will help them to burn calories fast. Yes, muscles burn more calories because they need calories to sustain them.So these body builders become natural fat burner with their high metabolism at this stage.

The cutting phase is when the bodybuilders cut fat from all over their body to get that ripped definition. For ordinary people in this phase, they will get to see their body toned up nicely, their six pack abs will also begin to show. So if you want to have a well sculpted toned body, then take this 2 step approach to build muscles first and then cut the body fat when you achieve the muscle size you wanted.

Bailout signals Lisbon’s capitulation to financial markets

Saturday, April 9, 2011

Having resisted financial-market pressure for months, Portugal has finally requested an International Monetary Fund (IMF) and European Union bailout.

The emergency loan, believed to total around 75 billion euros, comes three weeks after the country’s prime minister, José Sócrates, resigned following parliamentary rejection of his government’s proposed austerity measures.

Following recent sovereign debt crises in Greece and then Ireland, the Portuguese government’s actions have attracted harsh criticism in the European press. Applauding the request for foreign assistance, Britain’s The Guardian nonetheless lambasts Mr Sócrates for the tardiness of his decision. The British newspaper described Portugal as “the financial-market equivalent of a dead man walking” in an editorial dated April 7.

In Portugal, Público observed that “it will not be easy to accept more austerity, but it will be impossible to accept any more demagoguery, denial of reality, political incompetence or irresponsibility”.

The National Daily noted, however, that the “return of the IMF represents a stinging defeat for Portugal”. Indeed, the political intransigence since Mr Sócrates’s resignation on March 23 was widely viewed as doomed to failure from the outset. The Portguese request, pointed out Spain’s El País, “surprised no-one, but [had] been delayed for political reasons”.

These latest developments will no doubt fuel further criticism of the single currency. In Austria, Vienna’s Der Standard labelled the euro a “deceitful entity”, mocking the claim by European leaders that “States bailed out using taxpayers’ money will be able to repay their debts with restructuring”.

There have been widespread claims that a will to protect the euro has led Brussels to unduly downplay the gravity of the sovereign debt crisis sweeping the continent.

The emergency loan is expected to be delivered before Portuguese elections on June 5.

Bomb techs erred in South Los Angeles explosion, says city police department chief

Thursday, July 22, 2021

In a press conference Monday, Los Angeles Police Department (LAPD) Chief Michel Moore said their department’s preliminary investigation into a botched disposal of illegal fireworks on June 30 was due to an excess amount of explosives placed into a explosives disposal vehicle. The explosion occurred in South Los Angeles (L.A.), California, U.S. on East 27th Street, injuring seventeen and damaging vehicles and property.

Five members of LAPD’s bomb squad have been removed from duty, said Moore.

On June 30, LAPD officers discovered a cache of over 32 thousand lb (14,500 kg) of illegal fireworks at a South L.A. residence. Bomb disposal technicians responded by placing an estimated 16.5 lb (7.5 kg) of explosives, into a “total containment vessel”, or TCV, where they detonated the material. According to the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), technicians actually detonated 42 lb (19 kg) of explosives. The vehicle failed to contain the explosion and the blast injured seventeen people and damaged thirteen nearby businesses, 22 residences, and 37 vehicles.

The TCV’s capacity was 15 lb (6.8 kg) for repeated use, or 25 lb (11 kg) for single use, according to Moore. The containment truck had been used by officials for ten years, with the June 30 blast its 42nd usage.

ATF special agents are also investigating the LAPD’s actions. They expect to complete their investigation in the next one to two months.

The owner of the home where the fireworks were discovered, 26-year-old Arturo Ceja III, was arrested by LAPD and apprehended on suspicion of unlawful possession of destructive devices and child endangerment. Fireworks are illegal to possess in the City of L.A., and in unincorporated areas of L.A. County. Ceja posted the US$500 thousand bail for release. He is due back in state court in October.

Federal prosecutors charged Ceja III with the illegal transportation of explosives without a license. Prosecutors allege that Ceja III purchased the fireworks from Area 51, a fireworks dealer in Pahrump, Nevada, on the border with California. He was released on US$25 thousand bond pending arraignment, scheduled for August 2.

L.A. Councilmember Curren Price, Jr. criticized the LAPD’s bomb squad in a statement saying, “[i]t’s clear there was negligence involved and this instance shows zero regard for the people that reside in our South LA community. Every individual that I have talked to including myself wonder if this would have been acceptable protocol in more affluent areas of the City.”

The city opened a resource center for affected residents at the YMCA on East 28th Street, where residents can file claims against the city and receive referrals to mental health services.

On Tuesday L.A. City Attorney Mike Feuer said his office received 56 claims against the city, saying, “We’re trying to speed this up as much as we can […] this is an all-hands-on-deck effort to make sure that anybody who suffered because of that explosion gets relief as fast as possible, because they deserve it”.

Callers to Tuesday’s L.A. Police Commission meeting called for the police department to make reparations to affected city residents and businesses. Moore told the commission there were over 200 applications for claims seeking assistance.

Pakistani general election likely to be postponed

Monday, December 31, 2007

The electoral commission of Pakistan held a meeting today to decide whether the general election of the country will go ahead as planned next week on Saturday January 8, 2008. A firm decision is expected on Tuesday; however, according to CNN, Election Commission Secretary Kanwar Dilashad told The Associated Press that a recommendation has been made to the Government to delay the election. It has not been stated how long this electoral delay will be, as no new projected date for the election has yet been proposed.

Violent civil unrest has occurred across Pakistan following the assassination of Pakistan People’s Party (PPP) leader Benazir Bhutto; although this is now drawing to a close, its impact threatens to jeopardize the general election, combined with the aftermath of the state of emergency only recently lifted by President Pervez Musharraf.

Prior to her death Bhutto had accused Musharraf of attempting to rig the balloting and had called for a boycott. However, leaders of the PPP and other parties sympathizing with Bhutto’s view have now indicated that they will not boycott the election when it is held. It was announced yesterday that nominal control of the PPP will be held by Bilawal Bhutto Zardari, Mrs. Bhutto’s son; however his father, Asif Ali Zardari, has declared an intention to handle party affairs on behalf of his son, on the grounds that he is still “of a tender age” at 19 years old. Mr. Zardari has stated that the PPP will contest the poll.
