The results of this experiment support our hypothesis that a two-foot vertical jump did indeed generate a greater amount of impulse. However, we based our hypothesis on the assumption that a one-foot vertical jump would produce a lower amount of force in comparison to a two-footed jump on the basis of muscle use. Interestingly enough, that was not exactly the case. The average amount of force produced in a two-foot jump was 777.76 N, whereas a one-foot jump actually produced an average force of 889.38 N (Table 1 &2). However, when looking at the maximum force of both trials, the two-footed trial did in fact have the greatest applied force, which we had hypothesized. Therefore, it is difficult to conclude whether our hypothesis is rejected by the average force values or supported by the maximum force values. The reason why impulse was greater in a two-footed jump, besides its maximum force, was because there was a greater amount of time elapsed while the feet were in contact with the force mat. The two-footed jump had a time range of 0.91 seconds whereas the one-footed jump had a time range of 0.63 seconds. Be reminded that impulse is a product of force and time (Lawler, 2018). The relationship between impulse and time is directly…show more content…
It was studied in this lab how pressure and surface area are inversely related. A larger surface area plays a crucial role in dissipating the amount of pressure experienced by the lower structures of our body. Understanding the variables of pressure can help us note the differences between different shoe types, and in what manner they pose a risk for injuries. For instance, it has been studied that high heels, which have a substantially smaller area of impact, increase the amount of stress that the tissues of the foot experience (Snow et al.,
