Sleep in Sports Essay Example for Free

Sleep in Sports Essay Cheri Mah of the stanford sleep disorders clinic and research laboratory has been following sleep patterns and the effects on the athletes performance. One of her experiments was with the Stanford University tennis team. For five weeks each member of the tennis team was to get ten hours of sleep per night. Those who increased their sleep time ran faster sprints and played at the best of their ability. Mah found that getting extra sleep over a couple of weeks improved an athletes performance, mood, and alertness for all athletes. Sleep is very important for collegiate and professional athletes who have full schedules and often travel for games. Athletes can easily struggle with getting enough sleep due to being so busy through out each day. This slows down the athletes alertness and performance level to a minimum. Many athletes have set personal bests and have broken school and also world records by just getting enough sleep. The reason behind this is because while a person is in what they call deep sleep, is when a growth hormone is released. These hormones stimulate muscle growth and repair body parts such as bones and muscles. The hormones also help burn fat keeping the athlete in top shape. REM sleep also provides energy to both the brain and the body. If sleep is cut short, the body doesn’t have time to complete all of the phases needed for muscle repair, memory consolidation and the release of hormones. So how much sleep does an athlete need? The answer is seven to nine hours per night for adults and nine to ten hours for adolescents and teens. Athletes can tell by falling asleep within twenty minuets of going to bed and waking up without an alarm means that they are getting the right amount.

Addisons Disease Essay -- Disorder Endocrine System

Addison’s disease   Ã‚  Ã‚  Ã‚  Ã‚  Addison’s disease is a disorder of the endocrine system. It is a hormonal disorder that can strike anyone, any gender at any age. Addison’s disease has also been called Adrenal Insufficiency (hypocortisolism) because the root of the disease is in the adrenal gland not producing enough of the hormone cortisol, or sometimes not enough of the hormone aldosterone to satisfy the body’s needs.   Ã‚  Ã‚  Ã‚  Ã‚  Cortisol is in the class of hormones called glucocorticoids and affects almost every organ in the body. One of the most important functions of cortisol is to help regulate the body’s response to stress. Cortisol is also responsible for other necessary functions including: helping to maintain blood pressure and cardiovascular functions, helping to slow the immune system’s inflammatory response, helping to balance the effects of insulin in breaking down sugars for energy, helping to regulate the metabolism of proteins, carbohydrates, and fats, and helping to maintain proper arousal of sense of well being. The amount of cortisol is precisely balanced and regulated by the brain’s hypothalamus.   Ã‚  Ã‚  Ã‚  Ã‚  Aldosterone is in a class of hormones called mineralocorticoids which is also produced by the adrenal glands. The main functions of aldosterone are to help to maintain blood pressure and helping the kidneys retain needed sodium and excrete unwanted potassium to maintain the balance of water and salt in the body.   Ã‚  Ã‚  Ã‚  Ã‚  When adrenal insufficiency occurs, there are many s...

Pros and cons Co-education Essay

Pros: 1. The mixing of both the two sexes in co-educational environment eradicates the inherent shyness in each student. On the other hand, by studying and working in a mixed-gender school, students will be given facilities for expressing and sharing their own ideas or opinions in the presence of the opposite sex. Therefore, it provides students a great incentive to overcome their shyness and enhance their confidence. 2. It is manifest that in the future students have to live in a mixed-sex world and hence they should be well- prepared to easily integrate into the real life. A co-educational environment is reflective of today’s society since it offers students a valuable opportunity to get exposed to a broad exchange of diverse ideas, opinions, values and lifestyles; to get accustomed to working and sharing with their peer of the opposite sex. As a result, students in co-educational schools are more likely to adapt themselves into any new surroundings and get ahead. 3. In the past, education open to women was really restricted due to moral and religious grounds as well as the society’s conception of sex-role and gender-appropriate forms of work. However, with the worldwide advance of the society, there has been an overwhelming shift in women’s roles providing them with greater opportunity for involvement in life beyond the domestic sphere. Consequently, the practice of co-education has made the growth of women’s rights and the expansion of the modern education system to serve all the segments of the population. 4. So girls and boys in the class tend to compete in a healthy manner with each other. It is also seen that the girls fare better than boys in most of the cases. This is because both the sexes are enhanced by the presence of the other. In the olden times it was believed that girls were incompetent to compete with the boys but this is not true. Cons: 1. When studying together in a school, male and female students are likely to suffer from some bad distraction. For instance, some teenage students may be fascinated by their peer of the opposite sex and spend much time attracting them instead of their studying. Many school girls can be bothered by the teasing and even the flirting of the boys. If such distraction is not kept in control, then the students will be certainly lured away from their study. 2. While the world is witnessing dramatic improvements in co-education, there is a public question and concern about the connection among co-education and sexual freedom; a rise in unmarried, particularly teenage-pregnancy; and the growth of sex harassment and sexually transmitted diseases in mixed-sex schools where boys and girls students spend much time together and the safe boundary between two sexes can be broken at any time.

Nancy as the Most Important Character in Oliver Twist Essay

Nancy as the Most Important Character in Oliver Twist Charles dickens wrote Oliver Twist in 1837, during the Victorian era of England, he was born in Landport, a suburb of Portsea, on February 7, 1812. He was their first child of eight siblings. John Dickens, Charless father, was not good with handling the familys money. He was then imprisoned for debt on February 20, 1824. This experience left Charles psychologically scarred. Charles had to take the role of being the man of the house and had to start working at about the age of twelve. Charles Dickens attended school for a short while but worked the majority of his life.†¦show more content†¦This experience that young Charles has encountered drove him into getting a message across to the higher part of society (rich people), to help realize the poor, unjust treatment of the lower part of society (poor people). That is why Charles Dickens decided to write Oliver Twist in order to get that message across to the readers. When Oliver Twist runs away to London he meets Fagin and the pickpockets, at this stage of the novel young Oliver is naÃÆ' ¯ve, as he describes Fagin to be a merry old gentleman. There is a huge difference in the way that Charles dickens describes him, he describes him as, A very old shrivelled Jew, whos villainous looking repulsive face was obscured by matted red hair. During Victorian times, the readers would stereotype Fagin to be a greedy, selfish, unsympathetic and evil just for the fact that he was a Jew. To a modern audience Fagins Jewish ness could suggest that he is a victim of prejudice and has been discriminated. Which would push him towards leading a life of crime. E.g. in later times Jews were discriminated by the Nazis and treated badly as Shylock in the merchant of Venice. Dickens introduces Nancy to the readers through Olivers eyes.
