The precise quantification of the daily EE is necessary to investigate the amount of physical activity required to assess health outcomes. Therefore, it is very important to determine the absolute EE of occupational activities. With this aim, it is possible to quantify the EE of occupational activities using the \u201cCompendium of the Physical Activities\u201d, (Ainsworth et al., 1993), which includes the METs of several physical activities. The aim of this study was to collect data about the EE of an occupational activity which had not been included in the compendium: tile laying. 3 floor-layers were involved in the study (age 36 \u00b1 5, height 174 \u00b1 5 cm, weight 87 \u00b1 3, BMI 28.6 \u00b1 2.3, estimated VO<sub>2max<\/sub> 32.4 \u00b1 0.8 ml\u00b7kg-1\u00b7min<sup>-1<\/sup>). Each subject randomly carried out 2 trials (completing 12.5 m<sup>2<\/sup>), by simulating 2 typical work activities of this occupational activity: laying cement and laying adhesive. The activity investigated was divided into 2 phases:1) construction of a cement base (mixing the cement, transporting the cement with a wheelbarrow and, finally, leveling the cement); 2) tile laying. Respiratory gas were measured using a portable metabolic cart. The EE required to complete one square meter of cement base (71.1 \u00b1 12.7 kJ\u00b7m<sup>-2<\/sup>, or 17.4 \u00b1 3.1 kcal\u00b7m<sup>-2<\/sup>) and of tile laying (32.3 \u00b1 12.5 kJ\u00b7 m<sup>-2<\/sup>, or 7.9 \u00b1 3.1 kcal\u00b7m<sup>-2<\/sup>) were also calculated. The EE of \u201cconstruction of cement\u201d phase was 6.1 \u00b1 0.7 MET, or 38.0 \u00b1 4.2 kJ\u00b7min<sup>-1<\/sup>, or 9.3 \u00b1 1.0 kcal\u00b7min<sup>-1<\/sup>, with a final [La] of 2.9 \u00b1 0.6 mmol\u00b7l<sup>-1<\/sup>. The EE of \u201ctile laying\u201d phase was 5.6 \u00b1 0.8MET, or 35.1 \u00b1 5.0kJ\u00b7min<sup>-1<\/sup>, or 8.6 \u00b1 1.2 kcal\u00b7min<sup>-1<\/sup>, with a final lactate of 2.9 \u00b1 0.6 mmol\u00b7l<sup>-1<\/sup>. This occupational activity can be classified as Very Heavy (EE &gt; 31.4 KJ\u00b7min<sup>-1<\/sup>) or Heavy (MET between 4.8 and 7.1) (Bouchard and Shepard, 1994). Considering that each floorlayer usually completes a surface area of about 35 m<sup>2<\/sup>\u00b7day<sup>-1<\/sup>, the daily EE for this occupational activity (including both the construction of a cement base and tile laying) ranges from 3619 kJ, or 887 kcal. However, as the whole tile-laying procedure is sometimes carried out by two or more workers, those who only constructed the cement base (50-60 m<sup>2<\/sup>\u00b7day<sup>-1<\/sup>) reach a daily EE of 3555-4266 kJ\u00b7day<sup>-1<\/sup>, or 870-1044 kcal\u00b7day<sup>-1<\/sup>. In conclusion, this study provides useful information for a more precise determination of the total daily physical activity of floorlayers.<\/p>\n<p>9th Annual Congress of the European College of Sport Science (ECSS).<\/p>\n<p>Clermont-Ferrand, France, July 3-6, 2004<\/p>\n<p><b><\/b>Book of Abstract ECSS Clermont-Ferrand, 09-0796.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":18310,"template":"","categories":[862],"tags":[192,193,197,908,926],"class_list":["post-2739","attivita-scientifica","type-attivita-scientifica","status-publish","has-post-thumbnail","hentry","category-monitoring-en","tag-aldo-sassi-en","tag-andrea-morelli-en","tag-ermanno-rampinini-en","tag-franco-impellizzeri-en","tag-giglio-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>The energy expenditure of an occupational, physical activity: tile laying - Mapei Sport<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.mapeisport.it\/en\/attivita-scientifica\/the-energy-expenditure-of-an-occupational-physical-activity-tile-laying\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The energy expenditure of an occupational, physical activity: tile laying - Mapei Sport\" \/>\n<meta property=\"og:description\" content=\"Morelli A1, Sassi A1, Rampinini E1, Giglio P1, Impellizzeri FM1 1, Human Performance Lab, Sport Service MAPEI srl, Castellanza (VA), Italy The portable, indirect calorimeters can be used to estimate the energy expenditure (EE) during occupational activities.
