Maximum aerobic capacity of underground coal miners in

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 ...
