Abstract: | The aim of this study was to validate the Edholm scale (Edholm, 1966) and the ISO 8996 standard (International Organization for Standardization [ISO], 1990) by comparing the metabolic rates estimated for both methods with the actual measured metabolic rate (MMeas) in 6 manual material handling tasks simulated under laboratory conditions. The metabolic rate was calculated from oxygen consumption VO2 (19 participants) according to Standard No. ISO 8996 (ISO, 1990). Additionally, the participants estimated perceived exertion using the Borg scale. The metabolic rates derived from the Edholm scale (MEdh) overestimated 5 of 6 activities by 34-50% (α = .05). The metabolic rates derived from ISO 8996 (MISO) overestimated all activities by 7-38% (α =.05). |
