“Intoxicated by Water” In the September 1st Science Times, an article titled “Intoxicated by Water” was published. The article discussed the findings of Dr. Kevin Miller, an associate professor at Central Michigan University, concerning hyponatremia, a condition the body experiences if too much fluid is consumed in a short amount of time. This condition is also referred to as water intoxication. Water intoxication is very serious and, in some cases, can even be fatal. Dr. Miller’s research addressed the problem of telling athletes too drink before, during, and after workouts, whether or not they are thirsty. He found that athletes who abided by this rule could drink gallons upon gallons of fluids that their body did not need. The large amount of excess water if not lost by sweating or urination, instead entered the bloodstream. This decreased the …show more content…
Hypotonic conditions cause cells to lyse and burst. “Older Runners, Shorter Strides” In the September 15th issue of Science Times, an article was published titled “Older Runners, Shorter Strides.” This article explained a study done by Dr. Paul DeVita concerning slower running speeds found in older people. Many observations revealed that running speeds seem to decrease with age. For example, the marathon record time for a man around age 30 is over an hour less than that for a man in his 80s. Dr. DeVita sought to find why this occurs. He and his partner studied 110 runners and measured the force of their feet striking the ground, stride length, and speed. The experiment showed that older runners tend to use fewer muscles in their lower legs than younger runners. Next Dr. DeVita explored possible reasons why older runners do not use the same muscles. One possible explanation is that the muscles in the lower leg are prone to injury and early aging. To combat this, runners could strengthen their calf and ankle
All throughout an athletes life they are told to drink plenty of water, and replace their fluids. Athletes are told this enough to the point where it makes numbs them since they heard it so many times to the point where they forget the extreme importance of proper hydration, proper hydration. Proper hydration is not only key to optimum health, but also to great performance. Athletes are told to drink plenty of water, but do they really know why? It is this writer’s opinion that a greater understanding of proper hydration can lead to better health and performance for athletes and help spread awareness for dehydration and over hydration.
With age muscles tend to decrease in muscles fibres and when they do muscles become weak.
“In biological legs, the leg gets stiffer (or stays the same) the faster we run i.e. it bends less for a given force travelling through it. However, the opposite was seen for amputee runners, with a decrease in leg stiffness being measured for an increase in speed” (UKSportSci). Runners with prosthetics also have an advantage in the second half of the race because their prostheses get less stiff as the race goes on. However, normal runners start to stiffen up in the legs as the race goes on, forcing them to eventually slow down. A second benefit of the physiology involved with the prosthetics is that the energy exerted is much less than a normal runner. “The researchers concluded that Pistorius used 17 percent less energy than that of elite sprinters on intact limbs” (Greenemeier). Using less energy allows the prosthetic runners to stay fresh throughout most of the race. Generally, the hardest part of a race is the final finish, when the athletes competing are dog
Your running speed can be affected by many things such as, wearing jeans instead of shorts could that affect how fast or slow you go? Does the amount of food you eat affect your speed when you run? There are many questions you can ask yourself to what may affect your speed. This experiment can affect runners and athletes. Sunglasses being worn by runners can increase the speed of the runner. The invention of sunglasses has affected many people today, we use them for many different
Cohen first writes about hydration and how it has become the focal point of athletics. For example, Over the past few decades, the fear of dehydration has been indoctrinated into athletics, and professional athletes often blame dehydration as the cause of poor performance. Cohen then details the war between bottled water companies and sports drink companies. The sports drink companies advertise the concept that dehydration is dangerous, but drinking water is not enough. She proceeds to break down the contents of sports drinks to see the real benefits. She concludes sports drinks may benefit serious athletes. However, for the typical athlete, the sports drinks may do more harm than good. The drinks are heavy in sodium, which can lead to obesity. While this source is helpful, I may need multiple credible sources making these claims to help strengthen my conclusions on sports
e.g.: If person A has political power over B, then A is able to motivate, inspire, incite,
According to research, athletes will intake more fluids when beverages are cool, approximately fifteen ℃, flavoured and contains sodium or salt. This is why sports drinks are scientifically proven to help athletes.
Consistent with preceding literature (Jones & McConnell, 1999; Carter et al., 2000; Basset & Boulay, 2000), both men and women showed a significant increase in estimated maximal oxygen uptake on the treadmill ergometer, with a mean estimated VO2max of 50.5±9.4 mL/Kg/min compared to the cycle ergometer averaging a VO2max of 45.5±9.8 mL/Kg/min. The commonly accepted reasoning to account for this difference is that the treadmill running engages a greater muscle mass (the swinging motion of the arms and the stabilization of the core muscles) compared to cycling which predominately uses leg muscles and therefore leads to a greater demand for oxygen supply to skeletal muscle tissue resulting in a greater amount of inspired air and a greater maximal oxygen uptake value (Jones & McConnell, 1999; Carter et al., 2000).
When working out what is the best beverage to help benefit your healthy lifestyle? Is water the best or is a sport drink better. Gatorade has been around for recent decades, but what real benefits does this have. Are sports drinks affective or they part of a health fad squeezing money out of you. The question at hand is if sports drinks are vital for hydration or a waste of money. Addressing the real question of what is in sports drinks that actually help improve hydration or is it just sugar packed to give a person burst of energy, but don’t really give a long term effect. This article goes more in depth to how much hydration is needed and what is the best way to receive this whether is best from water of sports drinks specifically. The initial question this article ask is, “Do I really need a sports drink? Won’t water do?”.
Both professional athletes and normal people who exercise regularly are split between which is better to consume while working out, water or a sports drink? Although some people may say that water is better than a sports drink or vice versa, there are many benefits of drinking both beverages but one may be more healthier than the other.
Another study (Rowlands) concluded that sports drinks had a likely trivial effect on hydration as compared to drinking only water during exercise because it was not as isotonic as water. However, the study did support a role for carbohydrate concentration in fluid absorption, with the more concentrated Poweraid being absorbed more slowly than less concentrated Gatorade because it is more of a hypotonic solution. The current evidence suggest that a hypotonic sports drink provides minimally to moderately faster fluid absorption over water warranting further research into the practical implications of sports drinks over water because it may provide faster rehydration after and during sporting events.
Hyper-hydration does not provide any thermoregulatory aid and can actually lead to a deadly condition. Over-hydration occurs when the body takes in more fluid than it can remove and its normal sodium and other electrolyte levels are diluted. Also called dilution hyponatremia, this causes the bodies cells to swell (particularly brain cells) with water causing mild to serve health problems, even death. During exercise, renal blood flow (blood flow to the kidneys) is reduced resulting in decrease urine output. This decrease urine output does not allow the excess water to be expelled from the body. Accidentally consuming too much water is rare; most deaths have come from water drinking contests or from long moderate levels of endurance exercise during which excess amounts of fluids are consumed. Marathon runners are susceptible to this condition if they consume too much fluids while running. In 2002, a study done by the New England Journal of Medicine of the Boston Marathon showed thirteen percent of runners finished the race with dilution hyponatremia. The majority of these racers finished at the mid-to end of the race with 65% of them being
Wallace Stevens falls in the category with America’s most respected poets. Stevens wrote many of poems that got him to that prestigious category. Stevens was born in 1879 in Reading, Pennsylvania and he took his last breath in August 1955 due to cancer. Harvard University is where he was educated on literacy and was very successful at his time spent there. One particular poem he wrote is short poem “Disillusionment of Ten O’Clock” in 1915 and it was published in his first book of poetry at the age of forty-four known as, “Harmonium”. In the book “Harmonium”, Stevens published eighty-five of his best poems that a century later are still contributing to modern day poetry.
The level of internationalisation around the globe has grown throughout the years, with advanced technologies the ease and ability to work with foreign countries has also grown. However, firms do not simply interact with each other with no outside party involvement; the government can be seen to play a large role in conducting international business. Governments continuously have the responsibility to act in the manner that they believe is best for their nation; this includes decisions regarding protectionism, which may serve to aid domestic industries but simultaneously hinder international business. It can be seen that governments do not always act in their nation’s best interest and are corrupt which can serve to increase the risks and costs of entering an international business environment. While these are examples in which the government makes international business difficult it can also be seen that the presence of a government is instrumental in creating international business effectiveness, whether this be through their legal system or from trade agreements. This makes the role the government plays paradoxical; as their involvement generally increases the risks and costs of firms seeking to internationalise, whilst simultaneously playing a significant role in creating international business effectiveness.
The musculoskeletal system is also affected by physiological aging. A decrease in the body’s reaction time along with an increase in the degenerative process brings forth a higher risk of fractures, low back injury, tendon tears and effects of osteoarthritis.
