PalencianoAuthor: Montoliu, M.A.Notes: Sumario: Despite the ever-increasing mechanization of industrial activities, coal mining still remains a physically demanding occupation as it is not always possible to extensively mechanize the extraction process. To estimate the physical effort necessary to sustain coal mining activities in a poorly-mechanized mine, cardiac frecquency was measured throughout the working shift with a Sport-Tester PE3000 in a representative sample of 73 asturian miners engaged in a full spectrum of underground workRelated records: En: Ergonomics. - London and Washington. - Vol. 38, nº 6, June 1995 ; p. 1250-1263Materia / lugar / evento: ErgonomíaTrabajo físicoEjercicio físicoFrecuencia cardíacaCardiologíaOtros autores: González, V.
