Estimation of the aerobic capacity by step test in the workers of a tile factory in Yazd in 2017
Abstract
Introduction: Estimation of the maximum aerobic capacity to find a physiological fitness between worker and the work is of great importance. The purpose of this study was to estimate the highest aerobic capacity and physical work capacity of tile and ceramic workers. Materials and methods: In this cross-sectional study, 90 workers were randomly selected from tile and ceramic workers in Yazd. A questionnaire consisting of two parts was used as data collection tool. The first part of the questionnaire included demographic characteristics completed by the interview. In the second part, parameters including height, weight, BMI and heart rate were inserted in the questionnaire. The Queen step test was used to measure the maximum aerobic capacity. The data were analyzed by SPSS software using Mann-Whitney and Kruskal-Wallis tests and Spearman,s test. Results: The maximum aerobic capacity in tile and ceramic workers was estimated to be 3.60±.0.03 L/m. The results showed that aerobic capacity was significantly correlated with weight and body mass index. Also, there was no significant relationship between aerobic capacity, smoking and exercise, and education, but there was a significant relationship between gob title and aerobic capacity. Conclusion: Weight, BMI and type of occupation affect the aerobic capacity of workers.
