Heat And Dehydration Literature Reviews Essay

The results show the importance of consta t hydration during long exercise. The takeaway is that you need to be drinking during a workout and before/ after. Some people think you only need to hydrate before/after. This is false. Relation To Project: This is related to my project due to the fact that it shows exactly how extreme exercise conditions affect an athlete. I can use the information i n this article to not only create my own experiment to see how exercise and extrem e heat affects a runner, but can also use it to create a stronger argument for the ne ed of my project.

This is also another good example and it can show me some informa tion that ouldn’t be able to see in my own project. I will use this instead of recreating my own experiment. I can use this information instead now. These findings also sho w the reason Its so important to hydrate and how we can do it better. This is a direc t relation to my project. 2 Personal Reflection: Overall I really appreciated the article and the information it gives me.

Although some of the article is extremely hard to read and I can’t unders tand a lot of the words of the meanings, it shows the cause and effects of an experimen tl would most likely not be able to create in my own lab. There are way too many peo ple and quipment. This is a very good basis for the project and I am excited to use t his article. Hillman, A. R. , Vince, R.

This includes human cardiovascular, temperature regulation, body fluid balan ce, and aerobic performance. This article studies that these heated environments pr ovide for impaired aerobic performances and provide an explanation as to why. This ca uses a work overload and a stressful environment.

This studies the long term and sh ort term effects that might occur and how you can stop them. how extreme exercise conditions affect an athlete and it very much focuses o n the symptoms and the different ways that the problem can be solved. This again is another good way to gain background knowledge for everything that I will be testing a d experimenting on. I wish it talked more about ways to prevent and or recogni ze dehydration, but it still directly relates to the project. personal Reflection: Overall I enjoy the article and I think can learn a lot for it when I am doing my own experiments.

The article is very easy to read. It is also sim ple, short, and straight forward. The information will be extremely helpful and I like how you can gain so much information just for reading it. This article would have been mu ch better if while it was talking about the solution it went more into depth and maybe gav e me some more ideas.

Retrieved from http://jap. physiology. rg/content/1 09/6/1989 Literature Review #3 A Review of ‘Thirst and hydration status in everyday life. ” Summary: Water is extremely essential for all humans and maintaining a proper state of optimal hydration is very important for health. There are many physiologic al cue that tell you when to drink and there are many different factors as to why would w ould be or ot be hydrated. Does thirst really tell you when you need to drink? There m ust be another way to determine when you need to drink! In the end, this article is r eally about drinking to thirst and how we should actually tell when we are hydrated.

This is related to my project because it is all it is not possible to fully hydrate when you are only drinking when you are thirsty. It also talks ab out the causes and effects of only drinking when you are thirsty. This is related becau se my project is about a way to solve that fact that people don’t know when they bec oming 5 dehydrated or not. This will not only help me understand why this needs to b e solved, but it will also show me why this needs to be solved through a series of studie Hopefully this will help me come up with ideas when I am doing my actual pre sentation.

Personal Reflection: This article was very interesting and I enjoyed reading it I definitely think this article has a lot to teach me and I will definitely use it whil el am going through the stages of my research project. I don’t think there is much t hat can be improved in this articles, because the topic it is on is so on point with the topi c of our research assignment.

This is completely normal and part of regular body functions When a 6 subject has hit the “point of dehydration” have been argued and tested many different times. There have been many different studies, experiments, and tests to try and determine it yet.

So far nothing has exactly been solved. It is hard to determi because there are so many factors that go into it. The point is, drink more col d water will improve performance in exercise. Well the whole purpose of my project is to figure out when someone is dehydrated and then how we can alert them that they are becomi ng dehydrated. This journal goes into depth on the exact moment when someo ne IS ecoming dehydrated and how we can detect this exact moment. It also talks about how we can solve dehydration and the effects of cold water to dehydration.

We will use this information for when we are completing our human trials and discoverin g the actual way that we can alert people of dehydration. This will be helpful for when we design our patch. The Article is wonderful and I truly think it is going to be a help In the future. There were some parts of the article that I had trouble reading an d there were other parts that I just didn’t understand. Overall, the article is very inter sting and feel like I learned something new the entire time was reading it. I think it is v ery well written and would like to continue to read different aspects of this study.

It is also known that muscle glycogen must be restored after exercise. You can not restore fluids with food or sports drinks.

Drinking plain water is better than nothing, but drinking formulated carbohydrateelectrolyte sports drinks call allow for better exercise performance. The main idea is that there should be an alternative to water to drink before, during, and after a workout. This doesn’t include gatorade. This article is again just more information on dehydration which is not going to help with only my entire background knowledge, but it will also h lp me piece together different parts of the research assignment. This is also a nice helper, because it will make me think of other alternatives to solving dehydration and not just my own. When was finished reading, I was very satisfied. I loved the article and believe I learned a lot from it. I also think it will be very helpful w hen I am completing my research assignment on top of the fact that I can learn more a bout different alternatives. I don’t know why, but I simply don’t seem to agree with some of the information they talked about, and I wish they wouldVe covered some 0th er parts of dehydration. They basically said water is not that great for dehydration. I’m n ot sure how correct that is. Shirreffs, S. (2009). Hydration in sport and exercise: Water, sports drinks and other drinks.

Over the co urse of time, the subjects’ plasma volume (PV) was measured, along with an estimation of the c hange in hemoglobin concentration.

As a result, it was observed that dehydration, wh ether induced by heat, dehydration, or both, plasma rose. Both plasma glucose levels and plas ma in the blood were affected. It also mentions other research that yielded similar results in h umans. Primary. Relation to Project: Our project involves finding an efficient way to detect deh ydration. Any physiological change in the body due to dehydration will be important to us, cluding plasma volume. It will be difficult to measure plasma, as it lies in the blood, but it is st ill an interesting variable.

Hemoglobin in the blood was also decreased as the rabbits were tra nsported. Perhaps we can use a blood test in our project to make sure the dehydration i n our subject(s) is constant 10 Personal Reflection: This article and its results are interesting because it repre sents a possible way of testing for dehydration. While blood isn’t the best option, it is still good to know of every physiological change. A possible application for this informatio n to our project s to check the magnitude of dehydration and attempt to make it a constant in our su bjects, instead of continuous monitoring.

At first I was worried that the experiment i s done on rabbits, but upon further research, the results have been proven again and again. Nakyinsige, K. , Sazili, A. Q. , Aghwan, Z.

By Christian Poorten The effects of rehydration on cycling performance after exerciseinduced dehy dration” The objective of this research is to find a direct correlation be?veen exerciseinduced dehydration and performance, based on time trials. Subject s exercised at their own pace for a long period of time. There showed a direct relationship between dehydration and power output and performance. The temperature, exercise duration, exercise intensity, and length of the trials remained constant. In the end ther e were no significant differences between the experimental group that received no rehy dration period, 1 and the one that did.

Although, there were minor differences. It is speculate d that a cycling period of longer time will yield more positive results. primary. Relation to Project: This experiment relays important information pertaining t o our project. It confirms that there is a direct relationship between dehydration and athletic performance. Dehydration can now be confidently measured as a variable in exercise. We s hould also take from this that if we use the same subject, we should do each trial on different s days, as the effects last throughout the day. However, we will now most likely use as man subjects as possible to record many data points.

It also reminds us to keep as many cons tants as possible, including temperature, humidity, exercise intensity, exercise time. Personal Reflection: I personally believe that most of the data in this article is common sense, as most people know how dehydration affects performance in exercise. How ever, it does confirm this belief, allowing my group to proceed with our plan of using timed running trials to measure dehydration. The article helped by reminding me to keep as many c onstants as possible, especially in an outdoor setting that is difficult to regulate.
