IntroductionThis experiment was carried out to compare calf circumference as well as gender, weight and jumping height. If a person has larger calves, they will likely be able to achieve a greater vertical height. It can also be shown that if the person is a man, then he will be able to jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was taken into account. Therefore, a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs, leading to a higher vertical. Although males are thought to be bigger, faster and stronger, this leads us to believe that they can also jump higher. Men tend to have stronger muscles at almost all times of their lives (Burr, 1997). That being said, the aforementioned assumptions can be expected to be true because males are likely to have larger, and therefore stronger, calves. Men can also be expected to display a higher vertical jump (Caruso, 2012). Materials and Methods In order to begin this laboratory procedure, the class was first divided into groups of four. A measuring tape was then obtained from the laboratory equipment. 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 member of the laboratory and recorded in a table. This step was repeated for each member of the laboratory to obtain enough information for the data to be meaningful. After obtaining the calf circumference of each group member, a caliper was used to take the thickness of the skinfold inside the lab member...... middle of paper ..... Circumference (females) - Figure four displays the comparison of vertical jump to calf circumference measurement in female data. Calf circumference and jump height in women have been shown to have a negative correlation. Figure 5. Vertical Jump Range: This figure shows the vertical jump range for men and women and compares the two. The vertical jump height ranges of men and women overlap, however, females display a much wider range of numbers for the vertical jump. Figure 6. Relationship between men's weight, calf circumference and jump height – When compared, the relationship between men's weight and calf circumference and jump height results in a negative correlation.Figure 7. Relationship between female weight, calf circumference and jumping height – When compared, the ratio between weight and calf circumference and jumping height in women results in a negative correlation..
