The foot has been reported to be the site of injury in long distance runners in 5.7- 39.3% of all reported running injuries compared to the ankle (3.9% to 16.6%), knee (7.2% to 50.0%) and lower leg (9.0% to 32.2%). The integrity of foot arches plays a vital role in providing shock absorption in runners. Navicular height is a clinically approved reliable representation of medial arch height. Here navicular height was normalized to truncated foot length. This study is mainly intended to analyze whether anthropometric measures such as the height, weight and (BMI) to have an impact on medial arch height of the feet. Objective of this study is to find the correlation between anthropometric measurements and navicular height. 25 half marathon runners (13 females and 12 males) aged between 17 to 22 years were selected for this cross-sectional study, using convenient sampling method. The anthropometric measures like height, weight and BMI were taken. Medial arch height was measured by measuring navicular height in weight bearing position using the standardized protocol. Then navicular height was normalized to truncated foot length. All measurements were taken on both feet and analysed statistically. Normality test was established by Shapiro-Wilk test. As data has followed normal distribution, Pearson correlation coefficient (r) was used to report the association between the variables. BMI correlated negatively to normalized navicular height on both the feet (right r = -0.23 and left foot r = -0.52 respectively). Weight also correlated negatively to navicular height on both sides (right r = - 0.28 and left r = - 0.52). Height correlated negatively to navicular height on both feet (right r = -0.18 and left r= - 0.46). Two tailed independent t-test revealed no statistically significant gender difference on navicular height (right p= 0.41 and left p= 0.15). This present study revealed minimum to moderate degree of inverse correlation between anthropometric measurements and navicular height on the left side and little correlation on right side.
