Abstract: The shape of the pedis arcus affects the way of walking. Abnormal pedis arcus results in an unstable position of the legs as a body support when walking. This can cause several complaints such as imbalance, fatigue during long walks, pain and injury. Walking is one way to measure a person's fitness level. This study analyzes the relationship between the shape of the pedis arcus based on the foot print test and the VO2 Max value of FK UMSU students. This research is observational and analytical with a cross-sectional approach. The footprint test was carried out on 67 respondents followed by Clarke's angle measurement to determine the type of arcus pedis for each respondent. The body weight was then measured, followed by a six-minute walking test (6MWT) to obtain a VO2 Max value. The results obtained were that 36 (53.7%) respondents had a normal pedis arcus shape (normal foot), 13 (19.4%) high pedis arcus shape (cavus foot), and 18 (26.9%) flat foot arcus pedis shape. The results of the Somers'd test were symmetrical (P = 0.353), arcus pedis dependent (P = 0.353), and VO2 Max dependent (P = 0.353). A P-value 0.05 means that the variable of the shape of the arcus pedis and the fitness level (Vo2max value) is not proven to affect each other, so it can be concluded that the shape of the arcus pedis is not related to a person's fitness level.
