To investigate the difference of work intensity based on work form at plane and slope, 5 subjects performed sham weeding with a scythe and a weeding machine of gasoline engine in a laboratory. Expired gas was then analyzed and energy expenditure was calculated. Both at plane and slope of 20°, energy expenditure of the scythe work was significantly higher than that of weeding machine. And energy expenditure of the work with the scythe at slope was significantly higher than at plane, but concerning the weeding machine significant difference was not observed between plane and slope work. From this result, it was concluded that work intensity at slope was higher than at plane when the work was performed with legs actively, and work intensity did not differ when legs were used only to maintain standing position. At the same time it was revealed that the work with a scythe could be discriminated clearly from that with a weeding machine by means of a linear discriminant function constructed with 6 variables i. e. VE, ETO_2,FEO_2,ETCO_2,FECO_2,and VCO_2.
