Effect of a Sport Drink on Reaction Time Essay

Four interval times (PR, RT, TP and RR) measured in seconds were recorded both with the subject at rest and after the subject had exercised. The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise. More substantial changes were noted in TP and RR intervals. The TP interval decreasing from 0.32 seconds at rest to just 0.08 seconds after exercise, a decrease of 0.24 seconds (just 25% of the resting 0.32 seconds). The RR interval decreased from 0.84 seconds at rest to 0.61 seconds seconds after exercise, a decrease of 0.23 seconds

Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are

This study focuses on the effects of ingested caffeinated energy drink compared to placebo in three different sports, rugby, soccer, and volleyball. Each sport had a dissimilar number of participants, including male and female. The effects were analyzed under different circumstances in each sport performed. A few materials were used during the activities to monitor precisely the changes in all participants’ bodies. This study illustrates significant positive changes and improvement in all participants’ performances when they ingested a caffeinated energy drink.

ball that has been hit is .42 second. Their reaction time depends on a number of things. Such as

In addition to testing both males and females, three different age groups including 16-18 year olds, 21-23 year olds and 47-49 year olds will be have their reaction times assessed. Incorporating a range of individuals from teenagers to middle aged people will allow inferences to be made regarding the effect that age has on reaction time. Across the experiments, two other aspects will be varied including using dominant or non-dominant hands

It is important for anyone doing physical activity to keep well hydrated, for performance to be at its best. Sports drinks are specially formulated to help people rehydrate during or after exercise. Drinks such as Gatorade and Powerade contain the main electrolytes and carbohydrates, which are used by the working muscles, to maintain optimal sports performance (Medindia.net, 2014). The acidity of sports drinks and the sugars, is raising health concerns, and creates unnecessary calories. (Nutritionwonderland.com, 2014) Sports drinks are proven to only be necessary when working intensely for over 90 minutes, so an athlete running a marathon may need a Powerade, but water is the best source of hydration for exercise of 90min or less.

For this statistical test we can use the single sample research t-test, predicting that the runner pulse will be slower than the other athlete pulses.

Sports drinks can do things that water normally can't do. Water is useful by keeping hydration. Sports drinks can do more. According to Source A, sports drinks provide electrolytes and carbohydrates. Both nutrients offer energy boosts that can give longer workouts. Second, sports drinks have bette flavor than water. According to Source B, sports drinks are more appealing to people because of flavor. The flavor of the sports drinks are enjoyed by most people. This means that people will drink more of the sports drinks to have better hydration. Finally, sports drinks have better recovery than water. According to Source C, the type of drink to use depends on how long the activity was. Sports drinks are used for longer durations because the nutirents it gives. The added nutrients also give a performance boost, so sports drinks not only give energy, it also increases how well someone does an activity.

Staying hydrated when you are running is critical. It can be easy to become dehydrated when you're working yourself out and sweating up a storm, and this is even more of a problem when you like to run when it's hot outside. If you're carrying your water on you while you run, you'll be encouraged to take sips of water more often, which can help prevent dehydration. This can help you feel better while you are working out and can help prevent dizziness

The reaction time for the dominant hand was 0.391325815 seconds. The reaction time for the non-dominant hand was 0.380909054 seconds. The non-dominant reaction time was 0.010416761 seconds faster than the dominant hand.

In this experiment we first tried to find an experimental value for g. This was done by dropping a golf ball below a sensor that would read and chart the position vs time graph and the velocity vs time graph. From this we could receive an equation and numbers that are useful in finding the velocity and acceleration of the ball in order to find the experimental g value. Then we did another experiment in which we would hold out a ruler between another person's index finger and thumb and then drop it, measuring how many centimeters it took for them to catch the ruler. Using this and an equation we could measure their reaction time.

Sports drinks are full of minerals. The minerals are not only great for absorption but to replenish what a body loses during strenuous exercise. Usually replenishment of those minerals is only needed for long hard exercise. In an article from Men’s Fitness Magazine it explains that water is a great choice for light physical activity. It will satisfy thirst and hydration needs (Ward par. 2). This is because Quote Sports drinks, however, are better for long or vigorous exercise. In the article from Science Direct it explains that more than 60 minutes of intense activity depletes energy, electrolyte, and fluid reserves (Ward par. 2). That is why it is important to drink a something with the necessary minerals. When you work out, you lose chloride, potassium, and sodium through sweating and muscle exertion. At WebMD it states that the best sports drinks contain

The major reason anyone drinks fluid before, during and after physical activity is to replace the water that is lost through sweat. If the water isn't replaced dehydration will occur and performance will be hampered. The purpose of sports drinks is to help rehydrate your body quickly and help improve performance and productivity. This is accomplished through a well-balanced mix of water, sugar (carbohydrates) and salts (electrolytes), the major ingredients in most sports drinks. These ingredients, combined with a variety of fruit flavours, create pleasant tasting drinks that, according to the companies, are suppose to help your athletic performance. Results prove that commercial sport drinks generally accomplish what they set out to do.

If someone doesn’t have enough electrolytes in their system then they can’t function. Electrolytes are important because they are what certain cells-such as nerve, heart, and muscle- use to sustain voltages across their cell membranes. They are also what cells use to carry electrical impulses, as in nerve impulses and muscle contractions, across themselves and to other cells. Kidneys work to keep the electrolyte concentration in blood constant in spite of changes in the body. Again, when exercising, the body loses most electrolytes in the sweat; sports drinks which contain sodium chloride or potassium chloride are consumed after the workout to provide the body with the energy it just lost. They also contain added sugar and flavorings to the drinks to give extra energy and to make the drink taste better. People also drink other drinks after a workout because they feel that it obtains the energy more effectively.
