Abstract
Anthropometric measures such as height and age are used in equations for estimating
spirometric values for various populations, while some studies have reported significant
relationships between some spirometric, cardio-respiratory and endurance performance. Equations
for evaluating spirometric values are usually based on data derived from samples of certain groups
of people which may not be representative of the world’s diverse population. This study therefore
sought to determine the relationships between anthropometric, spirometric and cardio-respiratory
values of Kenyan elite endurance runners. Methods. Ten (10) male purposively selected elite
Kenyan runners volunteered to take part in the study. They were instrumented in anthropometric
assessments, spirometry assessments, and an incremental treadmill test to exhaustion coupled with
cardio-respiratory assessments. Results. Pearson correlation analyses show significant
relationships between subjects’ body height and peak expiratory flow (PEF) (r=.741; p=.002),
forced vital capacity (FVC) (r=.640; p=.010) and forced expiratory volume in one second (FEV1)
(r=.587; p=.021). The runners’ FVC and minute ventilation (VE) had significant correlation with
volume of oxygen consumption (VO2) both at submaximal (p<.01) and maximal levels (p<.05).
Sitting height recorded a stronger positive association with VO2 (r=.667; p=.009) than body height
(r=.564; p=.029), while the latter has a stronger positive association with submaximal endurance
speed (r=.668; p=.009) than the former (r=.617; p=.019). Dependent sample t test showed that
spirometric values are not significantly different from predicted values (p>.05), but maximum heart
rate was significantly lower than predicted (p=.001). Conclusion. Current spirometric prediction
equations that use anthropometric variables are fairly accurate. However, more studies are needed
to improve prediction and reference values for cardio-respiratory parameters
