Vertical Leaps Lab Report

The purpose of this lab was to determine whether females or males jump higher. This was measured by comparing the calf size and the height of leaps in both men and women. It is suggested that whichever sex jumped the highest, has a larger amount of fast twitch fibers. The size of the calf was determined by measuring the calf circumference and the skin fold thickness. To measure the calf circumference, I sat on a bench with my leg dangling over flaccidly. I then placed a piece of string around the thickest part of my calf. The length of the string was recorded in centimeters. The measurement was repeated twice near the original point of calf thickness. The average of these measurements determined my calf’s circumference. We used a caliper
The athletic participants’ calf sizes were typically between 30 cm and 32 cm, as well as 37 cm and 38 cm. All of the athletes’ vertical leaps were higher than 25 cm. This data displayed an inverse linear relationship between the leap and calf size; a best fit line could be drawn. The t-test produced a mean value of 30.2 +/- 4.2 cm. The non athletic participants’ data showed that the calf sizes varied, and the height of the vertical leaps tended to be lower than the athletes. The vertical leaps for the non athletes typically reached a 25 cm height or lower with a few outliers. This data displayed an inverse linear relationship, but a best fit line could not be drawn. The t-test produced a mean value of 25.3 +/- 7.8 cm. The t-test conducted on the vertical jumps between athletic and non athletic female participants indicated no significant difference (P value = 0.0918), but there was a large difference between the two groups. Figure 3 compared the vertical leaps of athletic and non athletic male participants. These results were used to determine whether training as an athlete had the possibility of increasing the height of the subject’s vertical
