COMPARISON BETWEEN ARM SPAN AND HEIGHT AMONG UNDERGRADUATE IN ACHIEVERS UNIVERSITY

This study investigated the relationship between arm span and height among undergraduate students of Achievers University, Owo, Ondo State, Nigeria. Accurate anthropometric measurements, particularly height, are essential in clinical, nutritional, ergonomic, and forensic evaluations. However, in cases where direct height measurement is impractical, arm span has been proposed as a reliable surrogate. The aim of this research was to compare arm span and height, examine the correlation between the two variables, and determine any variations based on sex among the university’s undergraduate population. A total of 80 students (comprising 40 males and 40 females) were selected using a simple random sampling technique. Standard anthropometric procedures were followed in measuring each participant’s height and arm span using a stadiometer and measuring tape, respectively. Data were analyzed using descriptive statistics and Pearson’s correlation coefficient to assess the relationship between the variables. The results revealed a strong positive correlation between arm span and height (r = 0.932, p < 0.001), with males generally exhibiting greater arm span and height than females. In most cases, arm span was slightly greater than height. Regression equations were developed to predict height from arm span measurements. The findings support the use of arm span as an alternative to height, especially in situations where direct measurement of stature is not feasible. This study contributes to the growing body of anthropometric research in Nigeria and provides useful reference data for health professionals, educators, and researchers.
