| Abstract |
To estimate the physical effort necessary to sustain coal-mining activities in a poorly mechanized mine, cardiac frequency was measured throughout the working shift with a "Sport-Tester" in a representative sample of 73 Asturian miners engaged in a full spectrum of underground work. The mean cardiac frequency in miners working at the coal face (33 subjects, mean age 32.7 yrs, age range 21-48 yrs) was 106.5±18.2 beats/min. In other miners (40 subjects, mean age 34.6 yrs, age range 23-48 yrs) the value was 103.1±17.7 beats/min. The absolute values of subjects' shift-average heart rates were not related to age, measured (treadmill) VO2 max or VO2 max per kg body weight, but there was a weak correlation between these three factors and shift-average heart rate as a percentage of its maximal value. Workshift peak heart rate was negatively related to age. This study provides the distribution of the overall cardiac frequency values likely to be found in subjects working in these poorly mechanized mines. However, average workshift cardiac frequency differs considerably from subject to subject and is largely unpredictable. Summaries in French and German. |
