Swimming Biomechanics

As I mentioned before swimmers aren’t based on their ability to master the techniques but also in the values they posses. The values they posses are respect, honesty, fairness and courage. I had to learn and use those values everyday I went to swimming practice. There’s one thing that I needed to have to become part of the discourse community, which was being passionate about swimming and not giving up. At the beginning it was really hard for me not to give up when I was exhausted, but after becoming more passionate for swimming I never gave up. There were moments when I thought of giving up, but I knew that if I really wanted to call my self a swimmer I shouldn’t give up and I didn’t. For example, once I was in a Swimming Festival in my High School where I competed the four different strokes. I always finished second in the 50-meter freestyle race, but that day I decided I would end up first place. The race started and I jumped into the water and started pacing my self so that I would finish strong. In the first 25-meters we were all tied up and I was starting to feel tired. But I knew I couldn’t give up, so I took a deep breath and pushed harder. I pushed harder and was able to win the first place. After this race, I realized that even though I felt like giving up, something inside me was telling me to push harder and that thought led me to success. I was able to

Thesis/main topic – Learning how to swim is essential for being around water, it will help strengthen a person confidence, improve your physical fitness, and provide an area for stress release.

Swimming is the ideal practice for some kids, beginning from the time they are children. Not just does it work muscles which would somehow or another be dismissed, it can enhance adaptability, stance and adjust and in addition lessen nervousness and animate endorphins. For kids with asthma, it can be the main route for them to practice without an asthma assault, and those with physical infirmities discover the weightlessness of swimming pool to make swimming moderately easy. It can likewise be utilized as a holding system amongst guardians and their kids with formative troubles.

The common physiological responses seen are apnea, decrease in heart rate, and peripheral vasoconstriction. The dive response in mammals tend to demonstrate bradycardia in order to elongate the duration of the blood oxygen supply to the organs. With this in mind, the participants of this experiment should see a drop in heart rate, and it should follow the trend established by Hiebert (2003). When it comes to various conditions in water the ability of the individual to hold their breath fluctuates from trial to trial. According to Andersson (2002), waters at different temperatures causes differences in the dive response. In colder waters, individuals seem to have a shorter breath hold than they would when in warmer waters. This was further confirmed by (Hayward et al. 1986). Individuals experienced a continual exposure to these conditions over subsequent trials for several weeks. In theory, when continually exposed to the same conditions an individual would become desensitized to said conditions. It is the hope of this experiment to demonstrate that there is a desensitization as well as explain a physiological reason behind it.

At every official USA swimming meet there must be a number of officials, including: timers, administrative official, turn & stroke judge, relay-start judge, chief judge, starter, and the referee (according to the USA swimming minimum standards guideline). There are many reasons to disqualify (DQ) in swimming events such as: going past the underwater limit, incorrect technique (kick, arms, a combination of kick and arms, etc), leaving the starting block early, etc. In some cases, swimmers will not be allowed to swim if the have unapproved swim wear, or equipment not allowed in races (fins, hand paddles, snorkels, kick boards, etc). The only stroke which does not allow multiple dolphin kicks underwater is breaststroke, the breaststroke uses an underwater pullout, in which the swimmer may only use on dolphin kick per

We hypothesized that humans would exhibit a diving response similar to aquatic mammals and birds. If the proposed hypothesis is right, then we should observe a decrease in heart rate from resting heart rate during test (simulated dive) treatment exposure, and we should not observe any change in heart rate from resting heart rate during control (breathing in air) treatment exposure. This can be explained by the fact that the diving response,

I began to recall the many years swimming has been a part of my life. When I was eight years old, my mom signed me up for our local summer swimming league, and that summer I realized that I loved to swim. When summer rolled around every year, I was so excited to start swimming again. When I entered into the seventh grade, I started swimming for my middle school’s swim team. At that point in my life, I swam for fun. Even though we competed in meets, I wasn’t a very competitive person until the my eighth grade year. In eighth grade, I began to take competing seriously and tried to focus on improving my times. I even joined Crawfish Aquatics, a swimming program that trains you on the off-season, that year. Then, I was given some devastating news.

Swimming is a competitive sport, but it is also a very fun activity. I also try to get better at swimming every time I do. I try to do more activities to become a better swimmer. Swimming interests me, because I have always loved to be in the water. I have since I was kid. It didn't take me long to learn how to either. Ever since I learned how to swim, I've always wanted to be in pool or ocean. Sometimes, I can't go swimming. The main set back is the weather. It's been raining almost too much lately. Usually the rain is followed by thunder and lightning. You shouldn't be swimming when there's bad weather; it's a safety precaution. I hope to gain that I'm better at swimming. I'm not horrible, but that's always room for improvement. I just would like to improve on a breath stroke and all the other different styles of

This study was designed to investigate whether or not humans have a diving response similar to aquatic mammals and birds. In other words, our objective was to determine whether or not humans, despite living predominantly terrestrial lifestyles, experience “diving bradycardia”, or reduced heart rate, when subjected to apnea in cold water (Moyes and Schulte 2016). Moyes and Schulte (2016) described the cardiovascular dive response as being “not unique to diving mammals, but instead [ . . .] a fundamental property of all vertebrates”. “Most animals reduce metabolic rate and redistribute blood flow to essential tissues when they are deprived of oxygen” (Moyes and Schulte 2016). We used this information to hypothesize that humans do indeed exhibit a diving response when subjected to cold water apnea.

When you 're in the water, gravity is much less important because your buoyancy largely cancels it out. The main force you have to think about as a swimmer drags water resistance. We 'll come to that in a moment. Another difference between water and air is that if you swim outdoors, particularly in the winter month, the water is much more dense than air and it removes heat from your body about 25–40 times faster than air at the same temperature. Because the water of density, it takes a long time to warm up. If you love science, but swimming scares you, you 'll find it very helpful as I did when I was learning to swim to think about Newton 's three laws of motion. Among the most fundamental rules of physics, these three basic principles are enough to explain completely the movement of almost every single object you 're ever likely to come across. Newton’s Laws of Motion corresponds with swimming. The first law outlines the concept of inertia. It says that things stay still or move steadily, unless some kind of a force is applied. The second and third laws are also of more interest. The second law explains the connection between force and acceleration. If you push or pull something, it starts moving or goes faster. The more force you apply, the more acceleration you get; the longer you apply the force, the bigger the change in momentum you can achieve. Where swimming is concerned, the third law is perhaps the most

This research paper is about learning to swim well, and it includes some important recommendations and warnings about swimming. Learning how to swim or improving swimming technique can in fact be an enjoyable experience. This research specifies step by step how to swim without any problem. People will learn that by practicing progressive swimming exercises with the proper mindset they can learn each swimming stroke step by step, quickly and have fun. The important thing about this paper is that people need to learn to be safe in the water for whatever situation might happen in the future, and that learning to swim can bring about self- respect, discipline, and confidence.

Participants for the study included seventeen national level swimmers (nine male and eight female, with >8 practices per week and >7years of training background). The mean age, body mass, and height of the males were 19.5 ± 2.6 years old, 73.5 ± 9.1kg, and 1.8± 0.09m. The mean age, body mass, and height of the females were 16.0 ± 2.8 years old, 57.7 ± 9.0kg, and 1.66 ± 0.03m. In preparation for data collection, swimmers were asked which turn style they preferred to use. Then, they underwent two practice and two

GO! My coach’s booming voice rings in my ears as I dive off the starting block. This is my 3rd 100 meter sprint, but it feels like number 50. The water feels especially heavy. Even though I’m breathing way too often, my lungs are gasping for air. I silently beg myself to kick faster, but then suddenly I am stopped. The rhythm of swimming has been interrupted. Another swimmer is in front of me, going slower than I would like. The splashes from her kicks blind me, and the swirling water makes it even harder to breath. I tap her feet once, twice, three times in the span of a few seconds. We are soon approaching the wall. I prepare to stop, thinking that she, like everyone else, will pause at the wall and let me go by. Instead, she flip turns and launches herself off the wall into another 50. I sigh, pause at the wall for a few seconds, launch off the wall yet again, only to be greeted by the familiar obstacle a few meters later.

The head is important. If the head is pressed down, the lower body will stay afloat. In our first few days, our class practiced 6’ foot and 9’ vessels. We had a small competition that checked to see which person could glide the furthest. The typical goals for the vessel competitions were 4 feet and 4.5 feet. This taught our class how to properly use our body in the freestyle stroke to eliminate drag. Another lesson we learned was to swim with high elbows. The pull of the water causes a lot of frontal drag and keeping closer to the water surface reduced the amount of drag. This was another way to reduce drag.

Divers swim several feet under water. Let’s try to think how their lungs are affected. Swimming several feet underneath the water’s surface makes it very hard to breathe. Imagine you are the diver, and you start off with lungs full of air. As you go deeper in the water, the pressure you experience in your lungs increases. When this happens, the air inside your lungs gets squished, so the volume decreases. This demonstrates __Boyle’s law__, which states that the higher the pressure (P), the lower the volume (V), as shown below. Here, k is any constant number.
