Intro The heart beats up to 200 times ever minute (American Heart Association, 3/22/13). On every beat the heart pumps blood, which carries oxygen, around the body to keep it alive. There about 5.6 liters of blood in a human body (Nova, 1997). A heart must keep all of this liquid in motion so the blood can supply oxygen to all the cells in the body. Death ultimately comes from the brain not betting enough oxygen and shutting down, which is caused by the heart being to weak (Wise geek, 2013). Normally the heart beats at a steady rate to move necessary oxygen around the body. There are many reasons a heartbeat will quicken; some can overload a body and cause injury. Two of the main reasons are surprises and intense, or dangerous situations. When surprised or shock, nerves instantly start to send messages to the brain on what. The body first releases adrenalin to give extra energy if needed. Once released the heart pumps rapidly to spread it throughout the body to prepare for fight-or-flight. Fight-or-flight is when the body decides to run or stay after, or during, an intense event. In a fight-or-flight situation the body gets tense, pupils dilate, blood pressure increases, and the body becomes alert (Science Group, 2011). In an intense situation, such as a battle, the body uses much of its energy to keep alert and focused. These things can often keep a person alive when in a tough place. When in a stressful or dangerous event the Hypothalamus, section of the brain, takes control and tells the nervous system what to do (Harvard Health Publications, March 2011). To keep focused and alert the heart must beat faster and make body stay active and ready. This rapid pumping of the heart usually causes people to sweat and tire d... ... middle of paper ... ...situations and made test subjects react to whatever happened in the games.

the heart is made of a muscle called the cardiac muscle unlike other muscles in the body the cardiac muscle never gets tiered its constantly working and never stops. It squeezes blood out of the heart and then relaxes it to fill it back with blood again in and this process continues and happens everyday until you are dead. The heart beats non stop this is achieved because of the cardiac Muscle.
Researchers, however, have found that gaming may not be completely bad for adolescents. A recent study by Paul J.C. Adachi and Teena Willoughby points out that video gaming may satisfy the same criteria for positive youth development as traditional organized activities such as sports, music or clubs. In direct contrast to this analogy, they demonstrate that there may be significant social benefits of gaming, that adolescents are motivated to play video games and that this type of play requires concentration and mental effort (Adachi and
“Most reported effects of videogames – particularly in the popular press – appear to centre upon the alleged negative consequences… Research has consistently shown that playing computer games (irrespective of genre) produces reductions in reaction times, improved hand-eye co-ordination and raises players’ self-esteem,” (Griffiths p. 47), states Mark Griffiths in his article, “The educational benefits of videogames”. When people think of video games, they often tend to think about the negative side effects that video games can have on a person. Will Wright in his article, “Dream Machines” also defends video games by providing positive effects that video games have on those who play them. Wright presents
There is much persistent debate throughout culture these days concerning video games. Common questions asked are things like ?Where should the lines be drawn in terms of content? and What audience, if any, is this appropriate for? As lawyers fight, bizarre crimes are blamed on video games, constant studies take place, and technology continues to evolve, the video game world continues to thrive and be extremely profitable. While there is near-constant focus on the supposed ?negatives? of games like simulated killing, drug use, or sex, most people, especially those completely outside of gaming circles, fail to acknowledge that gaming of any kind can possibly have positive effects on players. While increased hand-eye coordination is a common benefit attributed to gaming, one particular study conducted revealed a mixed bag of possibly positive and negative effects.
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
In recent years, technology has developed very rapidly. This has led to many arguably both positive and negative changes in our everyday lives. One such change was the increased accessibility of personal computers and gaming consoles as well as the introduction of numerous video games. Due to their entertainment value, these games gained popularity among children and teenagers. Although many concerns have been voiced related to playing video games, especially those that are violent, [e.g., increases in aggressive behavior in children (Anderson & Bushman, 2001)], this paper will argue that certain video games also have beneficial effects. They should thus be played by children, teenagers and adults alike albeit with caution.
By far the largest concern of technology today is video games. There have been so many experiments and studies to try and figure out if video games have a negative or positive effect on our children. A growing body of research is linking violent video game play to aggressive cognitive, attitudes and behaviors (D.A. Gentile, 2004). Video games can obviously be dangerous for our children causing aggression, bad performances in school and obesity. Although we cant blame all of these problems on the use of video game...
Tommy scuffles through the front door, drops his book bag on the floor and plops down on the couch with a scowl across his face. As his PlayStation fires to life, he replays scenes from the day in his head of being shoved into the lockers by Billy, unable to form the words to impress Sussie, and sitting alone at lunch listening to the popular kids laugh and joke, ignoring him as if he did not exist. No one understands him. No one cares about him, because he is not strong, charming, or popular. All that is soon avoided as Tommy dives into a world where he controls everything and everyone either fears or loves him. If he fails, all he must do is reset. Here he can be anything he wants, and he can do and have it all.
“As video games have become more violent and more sophisticated and the sales of video games has skyrocketed in the last few decades, youth violence has plummeted,” Ferguson says, citing evidence compiled by various federal agencies (Adams 3). Violence in video games is not a new issue. It has been debated and argued since the release of the first violent video game. As time has progressed, so has the evolution of violence and strong language within video games. Ratings have become more relaxed, and the lines between T (Teen) and M (Mature) rated games has gotten closer together. Violent games are becoming the normal and accepted of all games, and are being demanded by the gaming industry more heavily. Parents have always shied away from these games for their children, regardless of age. However, kids are getting these games whether they are the correct age (17+) or not. Young kids, less than ten years of age are playing horribly violent games and parents are fearing the repercussions. But video games are not to be blamed for child violence. Violence in video games does not cause children to become violent people later on in life.
Thirty that is the average age of people who play video games in America according to the ESRB. Yet when people talk about video games as a bad thing the topic that always comes up is that video games are bad for children and is going to rot their brains. But if people looked just at the numbers it could be seen that if video games really did rot people’s brains there would be millions of average American’s that would not fit in with the average public in the slightest. Why does this not happen. Because Video games are not harmful because society still functions, video games are used for training and for teaching, and video games bring people together.

A study was given to a thousand people ranging from 8 to 18 by Harris Polls, who conducts the interview to them. When conducting the experiment, they would look for symptoms by asking questions about video games that would correlate with other activities such as school. From there, the child can answer the question and the researcher can pin point the pathological issue with video games.
There have been several studies conducted on learning and serious games, for example, a recent study by the Office of Naval Research found that video game players performed ten to twenty percent better in perceptual and cognitive ability than non-game players, and that video games helped adults process information faster(Steinberg,2012). Another study by the Federation of American Scientists found that students re...
Nowadays, video games are frequently accused of having detrimental effects on children and adolescents. The main arguments against video games are that they lead to addiction, that they provoke violence, and that they impair social development. Whether or not such claims are true has not been determined with certainty as scientific studies have produced contradictory results. Nevertheless, video games also have beneficial effects, which tend to be underrated, as they do not receive the same level of media coverage that adverse ones do, and are thus unknown to the general public. Some of the positive effects of playing video games on mental development include: stimulating analytical thinking, improving concentration, and encouraging planning and anticipation (“Video game controversies”).
