IntroductionThis experiment was completed to compare calf circumference, as well as gender, weight, and jumping height. If a person has larger calves, they will likely be able to reach a greater vertical height. It can also be shown that if the person is a male, he will be able to jump higher. A larger calf circumference is more likely to reflect a high vertical leap since the fat content of the calves in the experiment was taken into account, so a large calf measurement in this experiment means a muscular calf. It is well known that more muscle will result in stronger legs which will lead to a higher handstand. Although males are believed to be bigger, faster and stronger, this leads us to believe that they can also jump higher. Males tend to have stronger muscles at almost all times in life (Burr, 1997). That said, the above hypotheses can be expected to be true because males are likely to have larger and therefore stronger calves. Males can also be expected to display a higher vertical leap (Caruso, 2012). Materials and methods To begin this laboratory procedure, the class was first divided into groups of four. A tape measure was then obtained from the laboratory materials. One member of the laboratory group sat on the edge of the table and the other members took turns measuring the circumference in centimeters at the widest part of the calf. The measurement was taken by each laboratory member and recorded in a table. This step was repeated for each lab member in order to obtain enough information for the data to be meaningful. After obtaining the calf circumference of each group member, a caliper was used to measure the thickness of the skin fold within the laboratory member... in the center of the paper... Circumference (females) - Figure four shows the comparison between vertical jump and calf circumference measurement in female data. Calf circumference and jump height in females have been shown to have a negative correlation. Figure 5. Vertical Jump Range: This figure shows the vertical jump range in males and females and compares them. The vertical jump height ranges for males and females overlap, however, females display a much wider range of vertical jump numbers. Figure 6. Relationship between male weight and calf circumference and jump height: When compared, the relationship between weight and calf circumference and jump height in males results in a negative correlation. Figure 7. Relationship between female weight and calf circumference and jump height: When compared, the relationship between weight and calf circumference and jump height in females results in a negative correlation.
