Description
Summary:Miners fitness test was assessed in terms of determination of maximum aerobic capacity by an indirect method following a standard step test protocol before going down to mine by taking into consideration of heart rates (Telemetric recording) and oxygen consumption of the subjects (Oxylog-II) during exercise at different working rates. Maximal heart rate was derived as 220−age. Coal miners reported a maximum aerobic capacity within a range of 35–38.3 mL/kg/min. It also revealed that oldest miners (50–59 yrs) had a lowest maximal oxygen uptake (34.2±3.38 mL/kg/min) compared to (42.4±2.03 mL/kg/min) compared to (42.4±2.03 mL/kg/min) the youngest group (20–29 yrs). It was found to be negatively correlated with age (r=−0.55 and −0.33 for younger and older groups respectively) and directly associated with the body weight of the subjects (r=0.57 – 0.68, P≤0.001). Carriers showed maximum cardio respiratory capacity compared to other miners. Indian miners VO2max was found to be lower both compared to their abroad mining counterparts and various other non-mining occupational working groups in India.
