The Effects Of Caffeinated Energy Drinks On Athletes Essay

This study targets the physical effect of caffeinated energy drinks on athletes in team sports, primarily the capacity of the participants to perform repeated sprints during a simulated match. Caffeine is a natural central nervous system stimulant. It is considered a drug that if is overly consumed can be dangerous for one’s body. Caffeine is a temporary energy booster that improves mood and alertness for most people, mainly athletes. It can be an eye-opener in the morning, could be drunk or eaten on practice brakes, and for some, it just became a habit that they cannot go through a day without a cup of coffee before exiting their doorways. Furthermore, it requires good health and stamina for athletes to perform throughout the game particularly the one in teams, such as rugby soccer, and volleyball. Have you ever wondered how their practices are like? How intense their exercises are? Coaches demand intense focus and will to push athletes to their maximum limit but some are still not satisfied, thus some athletes use caffeine as a stimulant to help them train better and for a longer duration. Methods To do this research, multiple key terms and references were used in the academic database search online to find what is needed.

Exercise 40 Chi Squared Free Essays

Researchers routinely choose an ? -level of 0. 05 for testing their hypotheses. What are some experiments for which you might want a lower ? -level (e. We will write a custom essay sample on Exercise 40 Chi Squared or any similar topic only for you Order Now g. , 0. 01)? What are some situations in which you might accept a higher level (e. g. , 0. 1)? An alpha level of 0. 05 is arbitrary and was set as a standard by scientists. One of the key concepts in hypothesis testing is that of significance level or, the alpha level, which specifies the probability level for the evidence to be an unreasonable estimate. Unreasonable means that the estimate should not have taken its particular value unless some non-chance factor(s) had operated to alter the nature of the sample such that it was no longer representative of the population of interest. (Price, 2000) As a researcher, you have complete control over the value of this significance level. The alpha level should be considered based on the research context and of the researcher’s personal convictions about how strong they want the evidence to be, before concluding that a particular estimate is reasonable or unreasonable. Price, 2000) An alpha level of 0. 05 is the recommended norm for a two tailed test. The alpha level should be considered based on personal convictions of how strong you want your evidence to be. The alpha level is the probability or p-value that the researcher is willing to accept as significant. It can also be interpreted as the chance of making a Type 1 or Type 2 error. When you set a more stringent (smaller) alpha le vel, like . 01 or . 001, (which decreases the probability of making a Type I error) you increase the likelihood of making a Type II error. Hence, it is suggested that an alpha level of . 05 is a good compromise between the likelihoods of making Type I and Type II errors. An experiment where you may want a lower alpha level (e. g. , 0. 01) would be for example a drug study for coagulation times. You would want to be certain the drug is effective, therefore a lower alpha level would be prudent. Within this same drug study, you would accept a higher alpha level when looking for drug side-effects. (University of Texas-Houston Health Science Center , 2013) References Price, I. (2000).

HTM 4DQ1 How would you explain the analysis of variance, assuming that your audience has not had a statistics class before? When examining the differences between two or more groups, you can use the analysis of variance which is known as ANOVA. This is a statistical technique that is used to compare the means or averages of more than two groups. There are three uses of ANOVA which are the one-way, the two-way and N-way Multivariate ANOVA. (Solutions, 2013) The determining factor when to use one of the â€Å"ways† is dependent upon how many â€Å"treatments† are used in the study. We use the term treatment because ANOVA originated in the 1920’s to test different treatments of fertilizers’ crop yields. (â€Å"Analysis of Variance,† 2012, p. 2) Here, we will cover the one-way and the two-way ANOVA. The one-way between groups, ANOVA is used when you want to test the difference between two or more groups. This is the simplest version of ANOVA. (Crossman, 2013) This could be used for example in a study on the ages of patients on different cardiac medications. Here we are only looking at the various ages of patients. The two-way ANOVA between groups is used to look at complex groupings. (Crossman, 2013) For example, the patient’s ages in the previous example could be extended to include the patients from other countries to see if the ages vary from those in the U. S. So you would have three two effects from this ANOVA: the effect of the ages and the effect of abroad versus local. Using ANOVA in this study, you could also add diet to see if there is any association between cardiac meds, patient’s ages, and differences of abroad versus local. ANOVA creates a way to test several null hypotheses at the same time. (Solutions, 2013) There are however, certain assumptions that need to be met for true comparison of means prior to conducting the analysis which are: 1. The population in which samples are drawn should be normally distributed. 2. Independent of case: the sample cases should be independent of each other. 3. Homogeneity: Homogeneity means that the variance between the groups should be approximately equal. (Solutions, 2013) â€Å"ANOVA is used very commonly in business, medicine or in psychology research. In business, ANOVA can be used to compare the sales of different designs based on different factors. A psychology researcher can use ANOVA to compare the different attitude or behavior in people and whether or not they are the same depending on certain factors. In medical research, ANOVA is used to test the effectiveness of a drug†. Solutions, 2013) References Chapter Fourteen Analysis of Variance. (2012).

Describe an example; what are the variables within your population (work, social, academic, etc. ) for which you might expect interactions? An interaction is the variation among the differences between means for different levels of one factor over different levels of the other factor. (Easton McColl, 2013) In statistics, an interaction may occur when considering the relationship among three or more variables. It describes a situation in which the simultaneous influence of two variables on a third is not additive. (PediaView. om, 2013) For example, an intra-operative vascular study on the use of gelfoam for topical hemostasis is being conducted. Half of the surgical patients received gelfoam with normal saline, and the other half received gelfoam with topical thrombin 5,000units/5cc of normal saline. All of the surgical patients received IV protamine to reverse the IV heparin. It was found that gelfoam with normal saline alone was effective, and gelfoam with t opical thrombin alone was effective in reducing bleeding in the operative site (main effect of gelfoam and main effect of gelfoam and topical thrombin with IV protamine). Also, for those patients who didn’t receive the thrombin, the gelfoam worked equally well (main effect of gelfoam); those who received gelfoam and normal saline got the benefits of both (main effect of gelfoam and main effect of IV protamine). However, it was found that those patients who receive gelfoam and topical thrombin got the benefits of both plus a bonus, an interaction effect (main effect of gelfoam with thrombin and the main effect of protamine plus an interaction effect).

1) In terms of its management and method of achieving objectives, Gore’s associates is very unique. Some impressive components of Gore Company are how the workforce/associates is set up in terms of innovation and cohesiveness, involvement of coaches and building and promoting of relationships and how less authoritative and hierarchical the company is. This is based on the fact that employees address each other by their first name and they are not obliged to disclose all information to their superiors, building company cohesiveness. It can also be seen that the company is well managed due to their sales level and ability to expand throughout the globe. These practices have broken the stereotypes taught in business school. 2) As unique as these companies are to one another, the competitive edge focuses around two main factors which are differentiation and quality. The primary goal of W.L. Gore was to create differentiated products to satisfy customer needs using PTFE and ePTFE methods and styles, clearly using a broad differentiation strategy as they appealing to a variety of customers in the areas of Electronics, Fabrics, Industrial Materials and Medicine. We will write a custom essay sample on Mystic Monk Coffee Case Study or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 3) One key approach used by W.L. Gore is that of their differentiated approach to leadership. This included many aspects such as having a variety of leaders such as plant leaders and functional leaders to handle various special tasks without consolidation of higher management. Also the reduction of job titles and hierarchy level allowed for better flow of information in the company which meant that there were faster transfers of information between associates which would contain ideas that the company can use to maintain or improve their current competitive advantage. Another aspect to maintaining their competitive advantage was through the use of rewards which were linked to achieving their goals and strategies. 4) The culture at Gore is based around oral communication and the building  and maintaining of relationships, flexible leadership styles and rewards. This was because W.L. Gore believed that these factors would allow for a more direct transfer for information and the building of relationships would allow for a better productivity level and overall running of the enterprise. It can be argued that this company’s culture is healthy and largely supportive of good strategy execution due to the fact that by building relationships, having flexible leader styles and a stable reward system, new ideas on differentiation and innovation of can come about so which can be consider by management. This would aid in potentially improving their competitive advantage by having new productions which are different from competitors. 5) Gore instills in culture through the use of various coaches/mentors, a system called â€Å"Gorecom,† for communication purposes and monetary rewards for contributions by salespeople and other employees. The role of monetary rewards through pay and non-monetary rewards through stocks served as a means of instilling and maintaining the company’s culture and strategy. This was because when objective are achieved both in the long and short-term, these rewards were given. Therefore, employees would work along the lines of what allows them rewards and this would maintain the culture of the organization. Due to this, it should not be difficult for Gore to staff managers to maintain and direct employees to upkeep the culture. 6) W.L. Gore’s view of leadership differs greatly from most companies. It was based on a dynamic and fluid process. Individuals who were not hierarchical leaders would sometimes step into lead based on factors such as knowledge of an areas or if they possessed certain skills. Leadership was basically seen as being without titles, hierarchy or official structure. Based on their culture of building relationships and being flexible it can be seen that leaderships does not play a significantly important role in the company. 7) Gore aid in achieving a cross-functional fit across their diverse areas due to the fact that they spread their culture and factors of it across the entire company. This culture aided in providing control over decentralized  operations due to the factors such as flexibility. Associates in various sections could be easily appointed leaders when needed and due to their expertise they would be able to maintain control and direct resources efficiently towards achieving the objectives of the section. This, couple with other factors such as reward pay, would help to maintain culture throughout the organization. 8) A major factor W.L. Gore Company would have to take into consideration is the fact that markets are constantly changing. Therefore the company would have to change some of its cultural factors and practices. They may need to interact on a more virtual level as rapidly changing markets would hinder travel between countries due to cost. They would also need to conduct research to find out how much of their businesses would still be in demand and then take the necessary action to either expand or close down the business.
