You will be analyzing the hyrdrodynamics of different swimming boxs - Lab makeup ExampleThe major purpose of this lab report was to analyze the hydrodynamics of different swimming strokes through considering several factors such as swim time, stroke frequency, stroke length and comprehend effort, in the comparison process.From the results, scenario B assumes a shorter swim time and higher stroke frequency than in the case of scenario A. Further, the perceived effort employ in B was less(prenominal) than that used in A. The reasons for the observed phenomena, depends on such factors like gravitational pull, friction force and right(prenominal) pressure. When a natator is partially submerged, as shown in A, there is increase in atmospherical pressure and gravitational pull acting thereby resulting in reduced speed. Further, while partially submerged, some parts of the body remain exposed to the air thereby triggering action of friction force between bathers body and air. At the s ame time, scenario A allows the subject to breath, which in turn reduces the stroke frequency because more time is spent in breathing. The mail service is different to scenario B, where swimmers body is ampley submerged in water leading to reduction in friction force, gravitational pull and atmospheric pressure acting. This triggers shorter swim time, higher stroke frequency and less perceived effort (Stager & Tanner, 2005).The results also manifest differences between scenario C and D, where dolphin kick was used for both with difference being one is submerged while the other is not. C, where full submergence was assumed, both swim time and perceived effort was less than D (not submerged. This can be attributed to the fact that dolphin kick becomes more effective when there is reduced friction and gravitational force through ensuring full submergence (Maglischo, 2003). The reduced forces leads to less perceived efforts and swim time as observed in scenario C. For situation D, mor e force is allowed to act on the swimmer in addition to efforts spent on breathing
