Investigating Oxygen Debt During Aerobic and Anaerobic Exercise
Introduction
During this experiment I am aiming to investigate the oxygen debt in
two people after exercise. During exercise energy is needed in the
muscles. Energy comes from food which is converted into glucose and
for the most efficient energy supply muscles also need oxygen. When
energy is produced using oxygen this is called aerobic respiration.
The formula for aerobic respiration is:
glucose + oxygen = carbon dioxide + water + ENERGY
During aerobic respiration the waste products are carbon dioxide.
Carbon dioxide is carried away in the blood and water is taken away by
sweating from the body.
When muscles do extra work more oxygen and glucose is needed, so more
blood must be pumped to the muscles causing the heart to beat faster.
Eventually more oxygen is needed in the muscles than is being inhaled
by the lungs so the muscles begin to work anaerobically. This means
oxygen is no longer used in the equation and the glucose forms lactic
acid. The formula for anaerobic respiration is:
glucose = lactic acid + ENERGY
During anaerobic respiration the waste product is lactic acid. Lactic
acid is a poison and causes muscle ache and eventually cramp. Lactic
acid burns up some of the energy being produced, therefore anaerobic
respiration only produces half the amount of energy that aerobic
respiration does. The only way to get rid of it is by oxygen breaking
it down, and the oxygen required to do this is know as oxygen debt.
The debt is the amount of oxygen consumed in recovery above what would
normally be consumed at rest in the same length of time.
The two people that will be taking part in the test are Lucy and Amy.
Lucy performs regular training for netball and for running and Amy
regularly trains for swimming. Lucy will be slightly fitter as she
completes more intensive training and she will also perform better on
the running tests because the muscles groups that are required for
running will be stronger than Amy who uses different muscles groups
Doodle’s brother is presented as a cruel person in “The Scarlet Ibis”. For example, when Doodle is born weak and on the verge of death, Doodle’s brother who wants a normal younger brother to play with “began to make plans to kill him by smothering him with a pillow” (Hurst 555). This quote shows that Doodle’s brother is willing to kill his newborn brother because he isn’t strong
In the novel, ‘To Kill A Mockingbird’ by Harper Lee some characters suffer in the hands of justice and fairness more than others. Many characters in the novel are discriminated against such as Calpurnia, Dolphus Raymond, Helen Robinson, Burris Ewell and more. However I will be focusing on the discrimination against Tom Robinson for his race, Walter Cunningham for his low socioeconomic status and Boo Radley for the rumors and supposed mental instability he holds. I chose those three because they are the most prominent and I will discuss how the discrimination against the characters therefore leads to their injustice or unfairness.
example he lets his kids call him Atticus, and let's Scout dress with the clothes that
Tom Robinson was negatively affected by racism because it lead to his death after an unfair trial. Atticus says “Tom was a dead man the minute Mayella Ewells opened her mouth and screamed”(Lee 323). Since Tom, a black man, was accused of raping Mayella, a white woman, Tom wasn’t going to win the court case because he was a black man against a white woman. Tom Robinson said ”Mr. Finch, if you was a n…. like me, you’d be scared too.”(Lee 261). This quote proves that Tom believed that he didn't think that he wasn’t going to win the trial, and that's why he tried to run from jail so he had somewhat of a chance. Tom Robinson’s life was ruined by racism was.
To Kill a Mockingbird is a phenomenal book that portrays life in the South during the 1930’s. This poverty stricken time, in which many struggled to get through, seemed to never grow dull by the means of the Finch family. Harper Lee’s award winning book was captured in a film containing the same title. Although the movie was in black and white and average in length, it lived up to the vivid story depicted within many pages. This worldwide hit reached many minds, but it is up to the people to decide which one is better: the book or the movie.
To Kill a Mockingbird by Harper Lee is a beloved novel published in 1960. After reading the novel there were some moments and people that I found particularly enjoyable. My favorite part of the novel was when the children went to Boo Radley's house to try to get a look at him. In addition, Atticus Finch was my favorite character in the novel. In my opinion the book was very good. I felt that it really showed the thoughts and actions, both good and bad, of the people in the South during the time of the Great Depression. At some points it was sad and at others it was comical but overall it conveyed the message that it was trying to send and everyone could learn something from it.
To begin with, Tom Robinson is an innocent being that resembles a mockingbird because he is falsely accused of raping Mayella Ewell. He is a black man that believes in equality. '''Yes suh. I felt sorry for her, she seemed to try more'n the rest of 'em-''' (Lee, 209) This honest statement Tom Robinson makes is a big mistake because back in the 1900s, there was a lot of discrimination which meant black people should never feel sorry for white people. It is a sin to kill Tom Robinson because he is a harmless citizen that means no harm to anyone in Maycomb. The death of Tom Robinson was typical to many white citizens in Maycomb because if black people were ever convicte...
...because of his race; one only needs a single bullet to kill. Tom Robinson most likely felt forced to take the easy way out in fear of putting his family in more danger and poverty. The fatal outcome of Tom’s trial helps to prove how disastrous racial discrimination's effect can be on people, no matter what race they are.
Tom Robinson should not have tried to escape prison for three reasons. He would not have lost his life, he would have proven himself innocent, and he would have made a statement of how it’s wrong how white people treated black people.
Due to the strong and growing evidence in scientific literature on the beneficial effects of physical activity on health and well-being, the importance of Clinical Exercise Science has increased. Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. Exercise, is a subcategory of physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components of physical fitness is the objective (http://www.who.int/dietphysicalactivity/pa/en/; last accessed on 30 April 2016). Generally speaking, Clinical Exercise Science is an applied clinical branch which deals with the application of various exercise modalities for
In the short story The Scarlet ibis, the author James Hurst suggests how choices can affect an individual’s life.
The story To Kill A Mockingbird has a wide variety of characters and situations that make it an all-time favorite. The ever-growing popularity of this story has caused a movie version, based on the book, to be showcased. There are noticeable differences between the two that could change the entire feel of the story. The omitted scenes from the book, that are never shown in the movie, include: Jem and Scout going to church with Calpurnia, the school scene in which the Ewells, Cunninghams, and Scout’s teacher and classmates are introduced and talked about, and how Aunt Alexandra, the great influencer of the children in the book, never appears in the movie along with other Finch family members.
Hydration is an important aspect that can contribute positively or negatively to an athlete’s performance. When an athlete becomes dehydrated, both mental and physical performance is affected, especially when heat is an environmental factor. This is a problem when high intensity exercise is involved in the training and participation of a sport. Coaches should be aware that athletes need to hydrate before, during, and after exercise in order to maintain optimal performance levels. There are different ways to maintain hydration.
Human development has drastically changed within the exercise and fitness industry since the 1940’s. This industry is now one of the largest, most studied, and sought out aspects of human life. Many people depend on exercise to sustain their health and change their bodies both physically and mentally. Specifically, many look to change their body composition, meaning how much muscular lean tissue and fat they have (Zanker, Cathy, and Louise). In many circumstances, such changes to one’s body are heavily scrutinized and evaluated against social norms (O’Donnell). Exercise to improve body composition can be done using two different methods, anaerobic and aerobic exercise. In regards to improving body composition, anaerobic exercise's effects are
