Validity Of A Badminton Specific Vo2max Test Physical Education Essay

Validity Of A Badminton Specific Vo2max Test Physical Education Essay The characteristics of badminton have been studied in detail in an attempt to further the knowledge of coaches and athletes in order to improve performance and training regimes (Chin et al, 1995; Hughes and Cosgrove, 2007). Badminton is a sport that requires repeated high intensity, short duration movements that places both the aerobic and anaerobic energy systems under physiological stress (Manrique and Badillo, 2003). During matches performers undertake bursts of high intensity activity followed by recovery periods regularly throughout the match. Matches at an elite level can vary in length from 20 minutes to an hour (Hughes and Cosgrove, 2007). Through the understanding of the sports technical, intermittent and explosive nature, athletes can train and prepare appropriately in order to meet the physiological demands placed on them during competition. During badminton match play, individuals require a combination of the aerobic and anaerobic energy systems, as well as the physiological requirements of power, flexibility, agility and movement speed, all of which are essential to provide effective match performance. During match play, it has been identified that individuals will maintain heart rates of over 75% of Heart Rate maximum (HR max) in the doubles discipline and over 80% of HR max in singles (Hughes and Cosgrove, 2007). In order for athletes to be able to perform successfully at these intensities for an extended period of time, their aerobic energy systems must be able to hope with such demands. In order for this to be possible training must be conducted appropriately and specifically enough to allow for successful adaptations to occur. This training can be undertaken through work within a gymnasium where aspects of cardiovascular fitness and strength and conditioning can be improved, alongside on-court training to improve technical ability and fitness. Knowing the effectiveness of certain methods of training can give athletes an advantage when it comes to competition. Girard et al., (2005) highlighted the limitations of using treadmill testing within racquet sports such as squash and badminton. They emphasised that exercise testing on the treadmill is not specific enough for the muscles involved in these sports and is therefore inadequate for evaluating the specific demands of the sport. Consequently, assessing the effectiveness of training adaptations in relation to match performance can only be conducted through the use of specific testing. This has enforced the view that, the development of appropriate fitness tests in sport is generally considered to be one of the essential tasks of sports scientists (Chin et a l., 1995). Chin et al., (1995) suggested that the customary standardised tests for aerobic fitness are not sufficient for an accurate prediction of successful performance in most sports, especially racket sports. They go on to claim that due to the intermittent characteristics of badminton, an accurate fitness test cannot be appropriately simulated in a laboratory situation. Therefore, it is necessary to assess physiological profiles of such sports during field tests. Wonisch et al., (2003) suggested that the direct measurement of respiratory gas exchange variables under field conditions may be useful in future research. They also suggested that further studies under competition-like conditions may provide additional information about the impact of aerobic power in badminton. Recent technological advancements have enabled the development of lightweight ambulatory metabolic devices allowing for an accurate evaluation of racquet sports such as badminton whilst on court. This has proved essential for assessing the specific demands of sport due to the ability to analyse and record specific physiological contributions to exercise, such as VO2, VCO2 and RER, within 5 second intervals. Studies which have used this method of assessing the physiological demands of badminton include; Roecker et al. (2005) and Faude et al. (2007). Previously, physiological profiling using mixing-chamber based metabolic devices have been undertaken in football (Ferrauti et al. 2006), tennis (Smekal et al. 2001), and badminton (Faccini and Dal Monte, 1996) but were all unable to attain accurate and sport specific values reflecting the physiological demands. Sport-specific fitness tests have been created for the Badminton England and the Welsh Institute of Sport. These field tests have been designed to be highly sport-specific and easily administered by players and coaches (Hughes and Cosgrove, 2007). These tests are able to assess; jumping ability, movement speed, and aerobic performance. These tests have been used to provide specific fitness testing results which can enable the coach to identify whether an athleteà ¢Ã¢â€š ¬Ã¢â€ž ¢s performance is being restricted by movement technique or general fitness (Hughes and Cosgrove, 2007). Recently a sport specific, incremental aerobic fitness test has been developed by the Badminton England. Hughes, (2003) designed the protocol that will be used to investigate the physiological responses of badminton performers whilst on court. This is aimed at participants reaching a point of exhaustion by the end of the testing. It is proposed that when athletes reach exhaustion during this type of test, VO2max values could be attained. This is what is to be studied during this research process and if found to be the case, this testing procedure could provide a more accurate and effective method of assessing VO2max, and could phase out the use of treadmill VO2max testing within badminton. Using a badminton-specific incremental test to generate VO2max results rather than the generic treadmill VO2max test can provide increased validity in the assessment of an individual badminton playerà ¢Ã¢â€š ¬Ã¢â€ž ¢s fitness level. It is important to be able to assess athletes in such ways in order to improve performance and adapt training regimes, especially at an elite level. However, as of yet there has not been testing conducted into the relationships between the three different endurance tests used in the study; the treadmill test and the on-court incremental test, which both provide measures of performance in terms of time to fatigue and the VO2 max result; and the speed endurance test which measures performance in terms of maximal speed, average speed and fatigue throughout the test. VO2max on-court is not only related to aerobic fitness, but also technique and the efficiency of on court movement. This is why it is important to investigate whether these tests are suitable fo r widespread use within badminton for accurately assessing individualà ¢Ã¢â€š ¬Ã¢â€ž ¢s playersà ¢Ã¢â€š ¬Ã¢â€ž ¢ fitness levels, as well as identifying the effectiveness of specific field testing for application within all sports. .

privacy :: essays research papers

It is just part of rules that some American private companies offer, there are many others rules which had been made and could be followed. But for Chinese industry there are less such industry moral principle to follow .In another aspect, only to take the way of self-regulation for industry, only to depend on the self-regulation of private detective company and the conscious of its employees, it is not enough obviously. So in America, the government still made several acts to restricted the industry, and protect the privacy. And for China the situation is different. Majority of people do not receive too well education, and quality of majority is not trustful, so we must make complete law, but not the model of self-regulation of people themselves. And we know there is no enough law about the protection of privacy especially for the Internet privacy of Chinese citizens. And in my opinion, Chinese government is in urgently needed to build law of privacy especial for the Internet privac y, and it should emphasize these following points. Principle 1 make clear the range of internet privacy, it will benefit to the judgments in law case. Principle 2 make clear how the data of individual in Internet is collected legally, and how the personal information in web site be used legally. Principle 3 emphasize on the protection of the peace for people to surf on the Internet, and avoid they were disturbed by spasm e-mail illegally. Principle 4 make specific act about the protection of children ¡Ã‚ ¯s privacy, because it is some different from the adult, and we can learn some from the children ¡Ã‚ ¯ privacy protection act in America. Principle5 make clear how to punish people who infringe other ¡Ã‚ ¯s privacy and digital privacy surely, in order to fulfill some vacuum of criminal law in China. 4.2 for Individual For individual, we should do more education, and make them to know the importance of their privacy, to be more careful when they was requested for the personal information. And encourage them to pay more attention to protect their privacy. In American, more and more employers are monitoring their workers on the job. In fact, according to the American Management Association, nearly tree quarters of U.S. companies now electronically monitor employees in several ways. And with China open to the world, more and more foreign company came to China, and those companies also take much action to surveillance their employees, much of this surveillance is legal, so in order to protect your privacy in the working place, individual need to know what he should do.

Cash Connection Essay

Allen Franks, President of Cash Connections, a short-term cash lending firm realized that the most profitable endeavor in the check-cashing store industry is to set up stores in towns where no check-cash stores exist. Setting up Cash Connections in these places, his business became one of the leading companies in his industry by the mid to late 1990’s. The payday industry grew from larger financial institutions leaving the market, huge overdraft and late fee costs, and increased regulation of the firms allowing higher consumer trust. In an industry that reaches to 10% of all U. S. households, advanced about $40 billion in short-term credit a year, and contributed $2. 9 billion in direct labor income, Cash Connection utilized Sun Tzu’s principle of attacking where unprepared to beat his competitors. Charging these enormous fees and costing only around $130,000 to start-up, the industry entails a lucrative structure. The Complication: There has been some concern for how high the fees are and how the model could take advantage of those caught in a troubling financial situation. Payday loans averaged around $300, and charged fees between around $15 to $20 per $100 loaned, resulting in an annual percentage rate of 520% (Gamble 2011). The media has decried this credit system as a predatory industry thrusting people into debt, which it no doubt absolutely has in some cases. The demographic of payday customers were middle income, earning mostly between $25,000 to $50,000 a year. They were usually of average education, made up of young families, and were a part of the somewhat normal working class. Many companies including Cash Connection had requirements such as holding a job and having a bank account in order to do business with the company. As media and public outcry have risen, lawmakers have begun to react and regulate the industry. The more it does so, the more people use it. On the state level, some completely outlaw it, as 13 currently have (Teegardin 2007). Some states limit the amount of rollovers the vendor is allowed to require, and all supervise with regulatory regimes.

Social Welfare Spending essays

Social Welfare Spending essays In todays world there are many issues that repeatedly appear on the front lines of the modern political battlefield: Fiscal Policy, Social Welfare, and Foreign Policy. These issues tend to become the main topic of political debates, especially around election time. While Fiscal and Foreign Policy are important, it seems that the topic of Social Welfare creates the most conflict. This may be because Social Welfare issues are directly related to Fiscal and Foreign Policy. The relation of these issues is simple. As the government creates programs to improve the standard of living for Americans in need it also creates debt. The amount of money that the government is willing to spend on the programs then becomes an issue introducing fiscal policy. This same process affects Foreign Policy through the amount of Foreign Aid provided by the United States to other countries and the debt it incurs by doing so. These issues are fueled by material scarcity and ideological differences, creating the proverbial double edged sword. The Republican Party believes that the government should help people as much as possible but with limited government intervention which usually equates to lower taxes, while the Democratic Party believes in Big government with many programs to provide for people in need. However by providing more services they inherently spend more money which means higher taxes. Sadly, as the political battle rages and the policies are created certain groups of people either are happy or enraged over the outcome. The ideological battle rages as topics of ethnicity and economic status are raised and challenged and people from all walks of life are added to the mix. Opinions are made lines are drawn and the issue is never truly solved. Many attest this is because of material scarcity and the fight between the Haves and the Have-Nots. This argument is painful to both ends of the spectrum because th ...

Comparison between Christianity and Hinduism based on the seven Essay

Comparison between Christianity and Hinduism based on the seven dimensions of religion - Essay Example On experiential and emotional dimension, Hinduism believes in Brahma the mother Goddess and the trinity of Brahma, Vishnu is the protector and Shiva the Destroyer and several hundreds of gods thought to emanate from the mother Goddess Brahman. In this tradition, God and trinity are one in their purest form and mother Goddess is worshipped. In the Christian traditions, God and the trinity are quite different. Some Christians worship Virgin Mary as the Holy mother. On narrative Christian traditions describe Earths creation, starting with the universe and final creation of man. Additionally, the early life of Gods creations is described, this forms the Old Testament in the bible, and later on the life of Jesus is narrated. In Hinduism, formation of the universe has been narrated, basing on the fact that it formed through a gradual process caused by Prakrit. On Social and institutional approach there are no rules on how God reveals himself, or how he chooses messengers in Hinduism. God i ncarnates himself, physically reveals himself or as such, chooses heavenly beings or a pure soul to accomplish his work. It is believed that, his final incarnation will happen at the end of this cosmic period. However, in Christian traditions it is believed that Jesus is no equal to man. it is believed that no more messiahs will come, until only the second coming of Christ. On ethical and legal rules, Hinduism believes in forgiveness, prayers, inner purity, as a way for earning Gods grace, and as a way for soul liberation. In the Christian traditions, such beliefs are the means by which man abides by Gods law and indeed personify the will of Jesus Christ as well as Christian values. Liberation from sin is not personally achieved but it is through the faith in Jesus and the teaching on Gods law. On Doctrinal and philosophical dimension, the bible forms the basis for the Christian principles and values. Indeed the Roman church acknowledges traditions in line with the bible as the prim ary source for the doctrine. Christianity has been instrumental in the shaping of Islam and Jainism. In Hinduism, the pillars of the traditions originate from the smritis, or as such the books of revelation. As such traditions, the epics, law books, and the writing of different philosophers serves as a guide to the spiritual life of the Hindus. Notably, Hinduism has been instrumental in shaping the history of Buddhism, Sikhism and Jainism. Lastly, on material Christians use Palm branches as a symbol of victory. The burning bush depicts Gods divine power. In Hinduism, the Om or Aum has been used as a symbol for piety where it is enshrined in Hindu temples and some family shrines. As such Om has been used to symbolize divinity, as well as authority. In addition, swastika is used which symbolizes the eternal nature of Brahman. Christian sub traditions include Catholicism, orthodox Christians, Protestants and Anglicanism. The catholic doctrines proclaim that the church is infallible to the dogmatic teaching on morality and faith. Protestants belief in bible authority, while Orthodox Christians is a set of governing churches affiliated to the eastern Christian traditions. In Hinduism, the main sub traditions include the Vaishnavism, Shaktism, and Shaivism as well as, Smartism. As such the denominations share common rituals and belief as well as, traditions. However, each denomination has its own philosophy concerning the achievement of the ultimate goal in life. As In this denomination, a follower believes in the deity Vishnu. Secondly, Shaivism forms the second largest religious community

Ecconomic globalization Essay Example | Topics and Well Written Essays - 250 words

Ecconomic globalization - Essay Example tion has led to economic growth by increasing the aggregate demand which increases exports as well as increasing aggregate supply through higher levels of investments that are associated with globalization. Globalization has led to destruction of jobs in the manufacturing sector and increase of jobs in the service sector. In addition to that, globalization has led to the increased demand of skilled labour and reduced demand of unskilled labour. This is because firms have shifted their some of their productions stages to countries with cheap labour only leaving the ones that required highly skilled man power within the USA. This has led to widening income gap in the United States of America (Hanson, 2006). Globalization has impacted positively on export and import trade in the USA. This increased trade has led to increase in the GDP of the country. However the effect of globalization on balance of payment is uncertain and it hugely depends on the relative growth rates, exchange rates and
