Physics can be applied to every movement, job, sport and task that we perform every day. Perhaps one of the most difficult sports in my opinion is competitive swimming. Swimmers work against many forces as defined later in this paper to move their bodies through the water. The most common swimming techniques and or strokes include the: front crawl, back stroke, breaststroke, butterfly stroke, sidestroke and the dog paddle. Swimming isn’t exactly natural for humans with the exception of being in the womb. Humans aren’t supplied with aquatic features that allow us to move and breathe freely in the water. This paper will explain some of the forces that are acted upon the human body while working to adapt to these aquatic conditions.
Propulsion
When analyzing the physics of swimming Newton’s three laws of motion are essentially the most important piece of information in the analysis of the different techniques of swimming. Propulsion is best explained by Newton’s First Law. Newton’s First Law: explains that force is a requirement in order for “to change the motion of any body, whether it is moving or at rest: Any body will remain at rest or in motion in a straight line with a constant velocity unless acted upon by an outside force” (Urone, 1986, p. 32). Newton's First law basically states that propulsive forces are important, should be amplified and strongly enforced. Resistive forces should be decreased as much as possible against the human body to allow it to perform skilled strokes with ease.
If we take this into consideration then the swimmer would be able to propel more efficiently. “In stages of some strokes there are no obvious forces occurring which is termed an "inertial lag". A common example is in "catch-up" stroking in c...

Imagine swimming in the big Olympic pools. All you can hear is the muffled noises of ecstatic fans cheering. All you can feel is the water urging you to keep swimming. Then you reach your hand out and feel the wall. You emerge out of the crystal blue pool water and have won! Michael Phelps and Dara Torres are two extraordinary swimmers who live their lives in the Olympic pools. Both Torres Is Tops and Michael’s Magic deal with the challenges and successes of Dara and Michael’s Olympic careers, but they do so in different ways. Let’s start our swim through the lives of these two Olympic champions.
Some goodness comes out of taking the risk of swimming alone. Ones“prohibition and expectations are ignored.'; The challenger of this feat has let go of all egoism as a result of the vulnerability faced.
When performing in a triathlon, which consists of swimming, cycling, and running in a single continuous event, it is generally accepted throughout the exercise science community, that “over performing” during the cycling stage by increasing ones cadence or aerobic power, could hinder the running portion of the triathlon that follows (Hausswirth). In order to help triathletes in avoiding this potential problem, the researchers set the purpose of the experiment as follows:
Swimmers tend to be tall and have a noticeable upper body muscle development. Having low body
Throughout literature countermovement jumps (CMJ) are seen to be higher in contrast to squat jumps (SJ) (Bobbert et al. 1996; Kubo et al. 1999; Bobbert et al. 2005). However present literature regarding the key potential mechanisms behind why greater muscle forces are seen accelerating the body upwards in CMJ in comparison to SJ is somewhat unclear. A CMJ can be defined as a positioning starting upright, beginning the descending motion in advance of the upward motion in contrast to a SJ where the start position is squatted with no preparatory countermovement (Akl 2013). The higher jump heights seen in CMJ in comparison to SJ are apparent even if at the start of propulsion phase the body configuration is identical (Bobbert et al. 1996). In past literature three main mechanisms have looked to provide an explanation for the greater muscle forces seen in CMJ than the SJ. The first plausible theory is that the muscle stretch in CMJ increases the production of force capability of the contractile machinery (Edman et al. 1978; Ettema et al. 1992; Herzog et al. 2003). Secondly the assumption that the muscle fibres are on the descending limb of their force–length relationship at the start of propulsion in the CMJ and SJ, however in CMJ the stretching of a chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992). The final explan...
What is Biomechanics? It is the study of forces and their effects on the living system (McGinnis, 2013). In this essay, I will be looking at the biomechanics of running. Running, as well as any other sport requires skills for which advancement is due to consistent deliberate practice and effective development. However, runners should establish a training system that actively builds their original running pattern instead of basing it on what works well for others. Understanding the biomechanics of running gives a better knowledge of their running techniques and points out areas of concerns that require improvement. Despite the fact that running is dependent on the interaction of the whole body, breaking down the running pace into single components allows us to further understand how minor changes can increase improve performance and decrease injury risk.
Gymnasts use physics everyday. As a gymnast I never realized how much physics went into every motion, every back handspring, every mistake on the bars. If gymnasts were physicists (or at least knew more about physics) they would be better equipped to handle the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same. I never truly understood why a particular angle gave me a better back handspring or why the angle that I hit a springboard at really mattered when completing a vault. We are going to explore some of the different apparatuses in gymnastics and a few of the physics laws that are involved in them. We will not even barely scratch the surface of the different ways that physics can explain gymnastics.
This force now can be used by the diver not only to go up, but to rotate and therefore perform various dives.
In swimming you turn direction when you get to the end of a swimming pool, for freestyle and backstroke you use a tumble turn to change. direction, in butterfly and breathstroke you have to touch the wall with two hands and push off the wall with your feet. Again, speed is only really important in hockey and football. In swimming. There are two types of course, short course and long course.
where p is the density of the fluid (in runner’s case: air); v is the velocity of the runner; A is the cross-sectional area perpendicular to the runner’s velocity; and D is the dimensionless quantity called the drag coefficient.
Surfing is the sport of riding a surfboard toward the shore on the crest of a wave. It is an amazing sport to learn and it gives the rider a hell of an adrenaline rush!! There are three major phases of surfing – paddling, push up and the standing position. This report will give you a full understanding of the correct techniques to use while surfing and it also describes the basic structure and function of the muscular-skeletal and cardio-respiratory systems of the human body. It will also describe the many different energy systems and how they change when surfing.

It is because of buoyancy that the people who swims, fishes and boats stay afloat(Buoyancy - Concept 2014).
The affects of swimming on disabled people’s bodies’ physically is colossal due to the fact that water provides support, stability, and has numerous healing mechanisms. According to aquatic therapist Stacy Bintzler, “Water has four main features that are not offered through land activity: buoyancy, resistance, support and hydrostatic pressure” which allows for simple movement to be less painful and easier in comparison to the same movements on land (Bintzler). Water’s main components aid in the following ways: buoyancy, reduces stress on joints; resistance, buil...
Any form of competitive swimming did not appear until the 1800s in Europe when schools accepted swimming as a natural part of life education. In the 18th and 19th century it became a competitive sport than being just a life saving skill. Swimming teams and clubs started to evolve all over the world. Although England was the first country to have an inside pool they aren’t one of the first countries of all times , China, Germany and Sweden were the first countries in swimming history. England and also invented the side stroke and after this one the freestyle evolved. Although there aren’t swimming competitions of side stroke it’s also known as a global stroke. In this essay I’m going to explain the changes of swimming for example the technology in swimming pools, the changes in bodies of the people that swam and more.
