Keywords: situational evaluation of coca cola
We can all proudly say for a beverage manufacturer like Coca-Cola that nobody is unacquainted with it in the entire globe as it has surely turn into a household name for all those. It will be interesting for us to know about its origin just before know its critical advertising approaches and company's belief to create it up to the stage.
Coca-Cola was discovered, we'd rather say invented in 1886, only out of curiosity to know what the mixture of certain ingredients does. It was John Pemberton, an Atlanta centered pharmacist, who created this amazing combination of fragrant and caramel coloured liquid. He then took that blend to the nearest pharmacy to obtain it carbonated and the thing that came up is now has become a greatest known brand nowadays.
In the initial stage, Coca-Cola had sold merely 9 glasses a day for an entire year. But, a century afterwards it has produced practically 10 billion gallons of syrup. After just three years of this invention, an Atlanta established businessman Asa Griggs Candler acquired rights of the business enterprise and brand in just £1500. Then became the first recognized president of Coca-Cola enterprise.
As a natural salesperson Asa Candler started out marketing the manufacturer in 1893. He discovered various brilliant and impressive tips of promoting the manufacturer. He started out distributing promotional coupons for complimentary preference of the beverage, and outfitted distributing pharmacists with clocks, urns, calendars and apothecary scales bearing the Coca-Cola brand. Persons saw Coca-Cola almost everywhere, and the aggressive advertising worked. That was the beginning it needed and efficiently achieved. Further the company grown following its expansion to the other parts folks territories and of the world.
During its journey from 9 spectacles a time to over 9 billion servings a day around the world, Coca-Cola Organization has struggled hard as time passes to safeguard the business and the brand. It has predominantly focussed on advertising as their main technique for expansion. Many company tags have changed every once in awhile like "Demand the original" and "Accept no Alternative". It was to make customers alert to brand's worth and keep them away from buying substitute products of Coca-Cola.

MAJOR COMPETITOR PEPSI INTERNATIONAL
PepsiCo is a world leader in convenient food and beverages, with revenues around $27 billion and over 143,000 employees. The company involves the snack businesses of Frito-Lay THE UNITED STATES and Frito-Lay International; the beverage businesses of Pepsi-Cola THE UNITED STATES, Gatorade/Tropicana THE UNITED STATES and PepsiCo Drinks International; and Quaker Food THE UNITED STATES, manufacturer and marketing expert of ready-to-eat cereals and different food products. PepsiCo brands are available in almost 200 countries and territories.
Many of PepsiCo's brand names are over 100-years-old, however the corporation is relatively adolescent. PepsiCo was founded in 1965 through the merger of Pepsi-Cola and Frito-Lay. Tropicana was acquired in 1998 and PepsiCo merged with The Quaker Oats Provider, including Gatorade, in 2001.would entertain the listener with www.testmyprep.com the most recent musical choices rendered by violin or piano or both. The new name, "Pepsi Cola", comes from the two of the principle materials, Pepsin and Kola Nuts. It had been first applied to the August 28. In those days, Bradham's marketing praises his drink as "Exhilarating, invigorating, aids digestion".
The advertisement of the Pepsi changes to, "You have a good choice baby, Uh-Huh!" .With the comprehensive usage of the superstars in the advertisings, the acceptance of Pepsi boost. In 1992 Pepsi-Cola shaped a partnership with Thomas J. Lipton Co. Today Lipton may be the biggest selling ready-to-take in tea brand in the United States. Outside the USA, Pepsi-Cola Company's soda operations are the business of Seven-Up International. Pepsi-Cola beverages can be purchased in more than 190 countries and territories.

PROMISE OF COKE
The standard proposition of our organization is simple, solid and timeless. Whenever we bring refreshment, value, delight and fun to your stakeholders, then we efficiently nurture and protect our brands, particularly Coca-Cola. This is the essential to fulfilling our ultimate obligation to provide consistently desirable returns to the owners of our organization.
Coke's commercials basically based on young generations, Therefore, the young generation is the target market of Coke because they would like to represent Coke with the youth and energy nevertheless they also consider about the old persons they take then as a co-target marketplace.
Major segments are quite simply those people who take this take daily and the ones areas where in fact the demands is higher then the the areas. There are so many persons who take this drink daily and those persons who take weekly and the ones who take less generally are always there as well. So, their basic segments are those persons who take this beverage regularly.
FACTORS AFFECTING SALES
There are so various factors, which influences the sales of coke. Below we are talking about three major factors which effects coke.
- Per capita income
Per Capita Income
First we will go over about "Per capita income". This is major factor that influences the sale of the soda. Because which every passing calendar year budgets have become very strict and limited to be able to purchase things. Therefore the disposable incomes of the persons are coming down. They spend seriously on rents, utilities, and education and fundamental necessities and from then on when they get extra money they look at this soft drink .Therefore the decreasing per capita income effects badly in advertising and production of the soft drink.
And to get through with this difficulty there is have to increase the degree of per capita money of Pakistan since it is much lesser than the rest of the countries.
Coke's major competitor is certainly "PEPSI" and there is absolutely no hesitation to say this because everyone knows that and all the other cold drinks and normal water, coffee, tea may be the competitors.
Weather is the third major element in effecting the Coke's selling. That is underdeveloped market therefore the coke's consumption in summers is 60% and in winters is certainly 40%.
MAJOR CUSTOMERS NEED
First of all majority don't care and attention that what they will have. Quite simply, they don't care and attention before drinking that whether it is "Pepsi" or "coke". They don't really actually differentiate between both of these brands in order to their tastes.
Consumers basically drink what they obtain.
They consider on "WHAT COLD THEY SOLD"
Consumer's availability in makes is actually works like:
Pull consumer's demand.
For this reason, Coca-Cola has presented their coolers and freezers available in the market. They have maximum amount of coolers and freezers in the market. They provide this infrastructure free of cost merely to provide child coke to their customer, which they wish to be purchase.
Their salesman and mechanics frequently visit all the outlets where coke features its infrastructure to check that either it really is in proper state or not, if certainly not then they immediately change or do the repair.
STRATEGIES OF QUALITY
After Micro and macro analysis Brand "coke" is generally role
- Enhance competition moments
- When persons watch cricket
- Through commercialization
- Fun time
Though these strategies, there may be better understanding and better reference to the public. These are the "key consumption".
THREATS FROM COMPETITORS
Threats are very well planned. Price is the major threat. When value goes selected beyond the actual price whether drop or increase its effects the consumption of soft drink.
Because when the price goes higher people go for the alternative of "coke" i.e. Pepsi.
And when price goes down they think that there is must be something wrong in it.
In short everything is determined by customer's perception.
TARGETS THAT WOULD LIKE TO ATTAIN
Every organization runs on the bases of income maximization so Coke can be buying high profit percentage.
There are three major ways of making money
- Overnight profit
- Windfall profit
- Ethical and un-ethical ways
Over Night Profits
They could be overnight profit that is for the number 1 brand for the entire year. This could be got my increasing revenue volume
There could be windfall profit. They are the extras income. When the consumption is on boom. Therefore, there is different sort of profits.
Ethical and Unethical Ways
Profit can also complete ethical and unethical techniques. They believe on this quote
"Everything is normally fare in love and war".
Some profits stays for quite a while like "overnight profits" and some just come and move like "wind fall profits". And they can also get profit through different approaches.
EXPANDING TARGET MARKET
In last 24 months Coke has come back in aggressive manner.
Consumer has choice
Attractive brand name
Consumer OFFERS Choice
Now the consumer offers choice. Because right now they know the brand of another big brand, though coke is the 2nd best name nonetheless it can get a better position after some time
Attractive Brand Name
Now the buyers know the Brand of Coke, because Coke may be the name, which is the most used following the word "ok". So people can better differentiate makes with one another.
Now different companies 've got different brand names. So, people can distinguish between makes. Two major makes "coke" and "Pepsi" also have brand names.
Coca Cola's Brand
Coca cola is normally "US" brand. Because they believe in the togetherness, being persons together and friends are testmyprep being collectively. Coca Cola strongly believes that Pakistani temperament is usually "US" not "Me personally"
Pepsi's brand is basically is basically "ME" branded. They utilize the temperament of "ME". In contrast to Coke they believe that on specific struggle.
THREATS AND OPPORTUNITIES FOR PRICE
is considered an extravagance product. Then there is the tax rate system
15% - sales tax
20% - excise duty
27% - would go to government
03% - To make Budget
After paying all these taxes coke must pay electricity charges. We must spend on distributions. After paying all these expenditures Coke's margin squeezed and customers have to purchase increasing tariffs.
These are the opportunities through which we are able to increase the price and can get profits.
There are much more threats in increasing prices. Because same problem of substitute. If Coke boost the price lets say 1 rupee. Then persons definitely won't choose coke. They have the very best substitute of Coke that's Pepsi. So they are the threats in raising prices. Coke will lose the margin of its income and will face loss.
STRATEGIES TO GETTING GOALS We.E. "HIGH PROFITS"
To boost the price is the least point, which Coke can adopt. There are so many ways through which Coke can improve the profits. Some major techniques are the following.
Volume could be increased
Interest degree of consumers
To be a part of energetic festivals
How to boost the level of consumers?
Coke can boost the volume by expanding the industry of coke. Through advertisements, offering different interesting things to attract people towards this product.
How to boost the interest degree of consumers?
Coke is increasing the interest degree of consumers by offering numerous flavors.
For case in point Coke is increasing the quantity of flavors in "Fanta", this is one of the product of coke. Through supplying unique flavors Coke can increase the Level of buyers and through this earnings can be gained.
How to be a part of energetic festivals?
Coke is already getting involved in the event like "Basant" since previous three years. Coke offers different beautiful things in their festival and through this Coke received high profit and usage of coke increased on these occasions.
And this year in this year 2002 persons were anxiously ready that what interesting issue coke is going to offer.
Our local marketing strategy enables Coke to listen to all the voices around the world asking for beverages that span the whole spectral range of tastes and situations. What people desire in a beverage is definitely a reflection of who they are, their current address, how they operate and enjoy, and how they chill out and recharge. Whether you're students in america experiencing a refreshing Coca-Cola, a woman in Italy going for a tea break, a child in Peru requesting a juice take, or a couple in Korea buying water in bottles after a run alongside one another, we're there for you personally. We are determined not merely to create great drinks, but also to contribute to communities around the globe through our commitments to education, health, wellness, and diversity. Coke strives to become a good neighbor, regularly shaping our business decisions to improve the quality of life in the communities in which we do business. It's a special thing to have vast amounts of friends around the globe, and we never forget it.
The total range of Coca Cola company in Pakistan includes:
And company offers their products in several bottle sizes these includes:
SSRB (standers size returnable bottle)
LRB (litter returnable bottle)
NRB (no go back bottle) or disposable bottle
PET 1.5 (1.5 litter plastic bottle)
CANS (tin pack 330 ml)
Coca cola products can be found in different packing
24 frequent bottle shell
6 bottle pack for 1.5 pets
12 bottles in a pack for disposable bottle
24 cans in a single pack.
Coca cola company offers incentives to middle men or retailers in approach a that they feature them free samples and no cost empty bottles, by this these stores and middle gentleman push their product on the market. And that's why coca cola seen extra in the market. And they have an excellent sale in the market because in line with the professional which product seen more on the market that sells more.
"Seen as sold"
They do agreements with a store keepers and retailers to exclusive sale in that stores. These retailers are called as Essential accounts in their local language.
And coke as well invest heavy budget on these stores and will be offering them free of charge samples and no cost bottles and some time cash incentives.
Different Price IN VARIOUS Seasons
Some moments Coca Cola Company change their product rates in line with the season. Summer is supposed to be a good time for beverage industry in Pakistan.
So in winter they reduce their rates to maintain their sales and profit. But normally they reduce the rates of their pet bottles or 1 litter cup bottle.
They gets or purchase shelves in big departmental shops and display their goods in that shelves in that style which show their product more clear and more appealing for the consumers.
Eye Catching Position
Salesman of the coca cola company positions their freezers and their products in eye-getting positions. Normally they continue to keep their freezers nearby the entry of the stores.
Company also do sponsorships with numerous college or university and school's cafes and sponsors their sports situations and various other extra curriculum activities for getting market share.
UTC mean under the crown scheme, coca cola quite often do this kind of scheme and they feature very helpful prizes in it. Like once they give bicycles, caps, television set sets, dollars prizes etc. This scheme is very much indeed popular among children.
Coca Cola Company would make two types of selling
In direct selling they provide their products in shops by using their very own transports. They have nearly 450 vehicles to provide their bottles. In this type of selling company have significantly more profit margin.
They have their whole sellers and organizations to cover all region. Since it is very problematic for them to cover all location of Pakistan by their personal so they have hence many whole sellers and agencies to assure their customers for option of coca cola products.
FACILITATING THE MERCHANDISE BY INFRASTRUCTURE
For providing their product in good manner business has furnished infrastructure these includes:
Free empty bottles and shells for bottles
Coca cola business use different mediums
Billboards and holdings
They often use printing press for advertisement. They contain a separate department for print mass media.
Pos material mean point of sale material this consists of: posters and stickers screen in the stores and in various areas.
As everybody understand that TV is a most common entertaining medium so TV commercials is one of the most attractive way of doing advertisement. Therefore Coca Cola Enterprise does regular Television commercials on different stations.
Billboards And Holdings
Coca cola is very much indeed conscious about their billboards and holdings. They have so various sites in different locations because of their billboards.
EXPECTATIONS FOR THE Approaching YEAR
Every issue starts from the frame of mind of consumer's patterns. And the basic key to attract the buyers is to throw the "money away".
And positive feeling felling with the brand, which they used to own Coke wants to advertise their products seriously in the year ahead. And it will have the 10% of their profits. And when we take it as a worldwide level it is $ I billion.
Coming year is the challenging yr for the industry of Coke. They have to take lots of decisions that how to increase the production and where they need to spend money.
For gaining victory in coming year they have to have some important things like:
Loyal consumers are important for company's success.
Workers ought to be the brand centric not really the promotion centric.
They should know just how much to for the company activities.
They should also know that how much to do with the promotion actions for brand.
HOW COKE DETERMINE THE YEARLY BUDGET
Coke determines its yearly budget by the
Coke determines its annual budget through the revenue volume. They first concentrate on the thing is "what is the health of their sales?" if the condition is very good of their sales they definitely increase their development and sales volume. Usually they concentrate on their old strategies.
The second thing by which they determines budget is the "profit" .if indeed they r getting income with the huge margin, then they definitely want to improve their profits within the next coming year. Every organization works on the basis to getting high profits. No business really wants to face Loss in their business. To get earnings is the first concern of the Coke.
To run the business enterprise every industry has some targets, that they want to attain in a specific time period. If industry achieves those goals in that period afterward for the year ahead it increases the volume of the mark.
So Coke Follow the same thing it has additionally some goals and targets to attain in the given time period. When they succeed to achieve that target then they increase their target volume in the next year.
Cardiovascular System in Parabolic Air travel and Spaceflights
Human Spaceflight: Alterations of the heart during parabolic flights and spaceflights
The purpose of this research is to recognize the changes happening during parabolic flights and spaceflights, where there's weightlessness. The need for the heart in space, is definitely recognised together with some of its fundamentals based on past researches. In addition, since parabolic flights are a method of experimenting physiological alterations in the human body, instead of actual spaceflights, the task necessary for the airbus to attain microgravity conditions is indicated aswell. Findings, such as for example low plasma quantity, circulatory pressure, central venous pressure, stroke volume plus the heartrate of the heart are explained from past investigations. Likewise countermeasures, such as exercise and diet are likewise briefly discussed.
Microgravity is the phenomena where items or people encounter weightlessness. Astronauts and objects encounter microgravity in space, where in fact the gravity is quite small (micro) plus they float (free fall). Even though astronauts are relatively weighty, they can move conveniently inside or outside the spacecraft (Wall structure, 2015). Under microgravity conditions, the physiology of the heart changes and it reacts unlikely in accordance with the gravity of the Earth leading to body alterations such as for example redistribution of bloodstream, cardiac arrhythmia and orthostatic hypotension (Zhu, Wang, and Liu, 2015).These changes might occur pre-flight, in airline flight or post-flight plus they may effect the astronaut's health. Additionally these changes can affect either healthier astronauts or astronauts with earlier heart diseases. Due to the environment, your body of the astronaut learns how exactly to adapt under the new conditions and works relatively quickly.
In order to research and analyse the improvements of the human being physiology, many microgravity based researches were conducted, not only by spaceflights but as well by parabolic flights and bed rest analyses. Measurements are used three phases of the astronaut's physique, pre-flight, in-trip and post-flight, known as the long length since astronauts are delivered to space missions while these measurements happen to be taken. Although, for more data, investigators were able to create microgravity condition for 20-30 seconds, using parabolic flights, referred to as the short-term duration, which is evidently a cheaper approach to collect data. Another way to review the adaptation of human being physiology in space is bed rest analyses, where volunteers dedicate up to 2 months in a bed, with their brain end at an angle of 6Â° under the horizontal axis. All volunteers eat, shower and exercise while they are during intercourse.
The cardiovascular system
In purchase to analyse the cardiovascular system in space, some fundamentals of the heart should be noted. A healthy heart is vital for astronauts likely to space, because the heart functions in a different way in microgravity and it is accountable for many main functions of your body. The physiology of the cardiovascular system in space, as a result will be altered and this can effects the function of the machine. Transporting nutrition (e.g. oxygen O2, meals) to the tissues of the body, waste materials removal (e.g. carbon dioxide CO2, by-products) and controlling warmth distribution between the body core and your skin (temperature) are some key function of the cardiovascular system (Evans, 2012). Heart is one of the muscles inside our bodies which is constantly in action and it is part of the cardiovascular system. This system also includes arteries, veins and capillaries, all referred to as blood vessels. Additionally, O2 and CO2 are provided and accumulated, respectively, to and from many organs, through arteries pumped by the heart and soul.Â Furthermore, the heart is accountable for the blood vessels pumped towards the heart, as a result of muscles of the hip and legs (Evans, 2012).
The cardiovascular system in weightlessness
When an astronaut is usually bare in space, the cardiovascular system learns how to function in this environment.Â The heart changes in microgravity, because the downward push of gravity will not exist anymore, as it existed on Earth's environment. Therefore, because of the insufficient the gravitational force, blood vessels and body fluids aren't uniformly distributed within the body, but moreover in the hip and legs, where each one of these fluids change upwards, towards the top, resulting for astronauts to possess "puffy faces" and not as much leg circumference (bird legs), as demonstrated in Figure 1. Liquid shift in your body, leads to the increase of the size of the heart, initially, as a way to handle the increase of the blood flow. This occurs through the first day of exposure in microgravity. Furthermore, due to the upward course of the liquids, astronauts do not feel as thirsty, resulting to the reduced amount of the fluid levels after the first time and
the center shrinks (Lujan, Bartner, and White, 1994).
Figure 1: Illustration of fluid shift level. The fluids happen to be distributed uniformly, pre-flight (left), fluids change, during flight ("bird legs" and "puffy faces")(middle) and post trip, the pressure is leaner in the upper body, due to gravity, creating faintness to the man. (Watenpaugh and Hargens, 1996)
Parabolic flights and the cardiovascular system
Airbus A300 'Zero G' may be the aircraft employed by the French firm Novespace for simulation of microgravity through parabolic flights, between 1997 and 2014 as proven in Figure 2. Organizations like the European Space Organization (ESA) and the German Aerospace Center, performed researches using this airbus in the mentioned time period, but by 2015 the brand new Airbus A310 'Zero G' changed it.
Figure 2: The Airbus A300 'ZERO-G' as it is flying within an incline of 40Â° to attain 0g. (Pletser, et al., 2015)
These aircrafts, were designed for researches because of testing outcomes before or after space missions, by obtaining parabolic flights under weightlessness for 20 seconds (Pletser, et al. 2015). More specifically, the airplane from a steady horizontal altitude, pulls up at an angle approximately 40Â° in an interval of 20s, resulting to an acceleration between 1.8 g and 2 g and therefore, the engines start to slow down, which leads to microgravity conditions in the aircraft as it gets to the peak of the parabola. Finally, the aircraft generates an acceleration of 1 1.8 g to 2 g, while flying back off with roughly 40Â° again for 20s and before returning to its initial steady altitude, repeats the manoeuvre right from the start, as shown in Figure 3 (ESA, 2004). In addition, parabolic flights can investigate the way the cardiovascular system of the human body reacts under 0-g conditions, within this period of time by spending relatively less money than actual spaceflights.
Figure 3: This number illustrates the manoeuvre that your aircraft (thick-black brand) follows to generate microgravity conditions and demonstrates the acceleration and the microgravity level as well. (ESA,2004)
Between 2010 and 2012, Novespace undertook an experiment based on the result of the cardiovascular system during a parabolic flight, using the Airbus A good300 'Zero-G'. The test out presents a short duration of microgravity, where the fluids inside the overall body are distributed. The center is pumped with an increase of blood than usual bringing on a rise of the blood pressure in the ventricles of the heart and soul. The stoke level of the cardiovascular system remained constant however the heart rate reduced by 14 min-1. Furthermore, it was explained that astronauts were within an environment, where in fact the body lacked adequate oxygen supply, referred to as hypobaric hypoxia state (HH) and since the study is usually under a parabolic airline flight, the gravity was shifting aswell. This sort of environment influenced the cardiovascular system, where the data received for the plasma quantity showed a decrease mostly due to HH, from -52 ml (hypobaric chamber) to -115 ml (parabolic flight) (Limper and Gauger ,2014). Another
research, compared the data for humans in supine posture, under ordinary gravity and microgravity in parabolic air travel (0G), which showed an increase in cardiac filling pressure resulting to the size of the left atrium to increase by 3.6 mm. Concurrently the central venous pressure (CVP) decreased by 1.3 mmHg but the transmural CVP improved by 4.3 mmHg. Finally, when an astronaut returns to Earth, because of the gravity, the blood circulation is reduced and that may cause define phagocytosis the astronaut to collapse (Watenpaugh and Hargens, 1996). These results were attained by researches, in order to investigate the consequences of the heart under weightlessness, by staying away from actual spaceflights, where these improvements are just temporarily.
The cardiovascular system during spaceflights
As quickly as astronauts get into space, the fluid levels in your body aren't uniformly distributed as they were on Earth, which leads to alterations of the cardiovascular system. As it was talked about in parabolic flights, the astronauts happen to be under hypobaric- hypoxia conditions, meaning that the oxygen saturation reduces (SaO2) and hence the oxygen in the blood. It has been explained that the concentration of O2 in the blood vessels can drop right down to 75%, where usually this levels ought to be more than 80%, but if the astronauts stays in space for longer, this concentration increase back to 85% (Opatz and Gunga, 2014). Furthermore, the mass of the heart and soul decreases during spaceflights and therefore the heart rate is significantly less than that on the planet. In 1996, it was reported that the heartrate would increase as the astronaut continuous to be under microgravity circumstances, throughout a long-term spaceflight (Charles, Frey, and qualitative observation example Fritsch-Yelle, 1996). In weightlessness, significant results were likewise realised, the cardiac result raised whereas the systolic and diastolic pressure decreased (Hamilton, Sargsyan, and Martin, 2011). Hence, stroke volume is also reduced, due to hypovolemia which is in charge of hypotension and atrophy of the center (Levine, 1997).
Investigators postulate that plasma quantity decreases from the first of all day and it continuous to reduce through the entire whole spaceflight by 17%. This occurs, because of the negative liquid distribution and the liquid activity towards the extravascular space and therefore the orthostatic intolerance (Alfrey, Udden, and Leach- Huntoon, 1996). A study reported by J.C Buckey et al. 1996, studied the central venous pressure (CVP) in space and stated that the CVP increases through the launch and extra in the spaceflight. The remaining ventricular end-diastolic volume (LVEDV) was as well analysed so as to figure out how it really is damaged by microgravity. Furthermore, it had been explained that as astronauts go into space, the LVEDV and therefore the total heart volume increases significantly. As the astronaut is usually in space, the body adjusts to the surroundings resulting to the LVEDV to diminish (Buckey Jr. and Gaffney, 1996)
For short duration publicity, effects are significantly less than actual spaceflights where the duration could be a lot more than 6 months. It is really very important to astronauts to be healthful during a mission, therefore some activities should be used purchase to counteract these threats of their physiology. It has been reported that somatic stress and anxiety in weightlessness results the cardiac arrhythmia (Romanov et al., 1987). The astronauts must exercise and have a healthy diet plan, before and through the spaceflight, to ensure the appropriate volume level for extravehicular actions (Hargens, 2009). Also, the low body detrimental pressure (LBNP) should be exercised regularly since it increases the plasma volume level (Watenpaugh and Hargens, 1996) and actually, aerobic fitness exercise keeps the aerobic quantity (peak of VO2) constant. For long-term publicity in microgravity, exercising equipment, supplied in the spacecraft can decrease the effects of the physiology of the astronaut after time for Earth. Although, studies have not shown this amount and kind of training, that astronauts should do, however (Schneider and Watenpaugh, 2002).
Discussion and Conclusion
Researches in the last 20 years, examined how the cardiovascular system adapts under microgravity circumstances, in order to provide astronauts with a safe performing environment and physiology. Astronauts will be sent to space to test experiments for the future of science, but their lives shouldn't be at risk. Due to microgravity, several attributes of the heart are affected. The fluids in the body of an astronaut uncovered in microgravity, change head-wards as a result of missing gravitational force. So, plasma volume level and mean circulatory filling pressure are decreased. Consequently, there are results on the central venous pressure (CVP) and stroke volume level, which both are reduced during weightlessness. The heart rate is also declined due to these changes, so as to maintain the arterial blood pressure and metabolism. Many of these parameters can affect drastically the astronaut's health and in rare cases may cause tragedies, since they are lengthy- term flights. Although, when topics are under investigation in parabolic flights, these improvements are only temporarily. Also, countermeasures, such as for example aerobic exercises and healthy diet, before, after and during the spaceflight are required. These actions may decrease the orthostatic hypotension of astronauts during flights but also because they return back to Earth. Extra experiments will be carried out in the future, where researchers will have an even better knowledge of space environment and the physiology in it.
