A Small‑scale Cross‑sectional Study for the Assessment of Cardiorespiratory Fitness in Relation to Body Composition and Morphometric Characters in Fishermen of Araku Valley, Andhra Pradesh, India

Background: The people residing in coastal areas of Visakhapatnam are mostly engaged in fishery, which is always been a physically demanding job, and numerous factors have direct or indirect impact on the health of fishermen; but, the data about their physical fitness or health status is quite scanty. Thus, the present study was conducted to assess their cardiorespiratory fitness pattern, as well as morphometric characters, which may be influenced by their occupation. Methods: In this retrospective cohort study, 25 young fishermen (mean age of 22.8 ± 1.92 years) were randomly selected from Araku valley of Visakhapatnam District, Andhra Pradesh and compared with 25 subjects who were randomly selected from college students (mean age of 21.9 ± 2.25 years) of Kolkata, West Bengal. Some physical and physiological fitness variables including height, weight, body mass index, body surface area, physical fitness index, anaerobic power, and energy expenditure were measured along with their morphometric characters. Results: Analysis of data indicated a significant difference in blood pressure, physical fitness index, energy expenditure, body fat percent and anaerobic power among fishermen compared to controls. However, there were no changes in morphometric characters between the two groups. Conclusions: Findings of this small‑scale population‑based study indicated that health and physical fitness of young fishermen is under the influence of both occupational workload and nutritional status, as found by body composition and morphometric characters.
