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.

Abstract
Introduction: Prevalence of musculoskeletal disorders (MSDs) is high among office workers. One of the most important risk factors of these disorders is awkward posture and inappropriate environmental conditions. So, this study was carried out to determine frequency of MSD
S and its related risk factors among the office workers of Minab city healthcare centers in 2018.
Materials and Methods: This cross-sectional study was conducted on 104 staff in Minab city health care centers. Nordic musculoskeletal disorders questionnaire was applied to determine the prevalence of MSDs and Rapid Office Strain Assessment (ROSA) method was used for posture analysis. The data were analyzed by SPSS version 21 using descriptive statistics and chi-square test. Excel software was used to plot the graph.
Results: The highest prevalence rates of MSDs were reported in low back (63.5%), neck (51.9%) and upper back (50%). There was no significant difference between MSDs and age, sex and BMI (P˃0.05) but there was a significant relationship with work experience (P˂0.05). Totally, 36.6% of employees were placed in the first priority of corrective actions (i.e. the need for ergonomic interventions as soon as possible). There was a significant correlation between awkward posture and neck pain (P <0.05).
Conclusion: The frequency of MSD
S in health center office workers was high and neck pain was related to awkward posture.
