forbrænding - siddende vs. stående arbejde

Hej Alle,

Jeg er i den lykkelige situation at jeg netop har fået nyt arbejde :dance:

Det er jo super fedt, men det er desværre også et kontorjob dvs. stillesiddende arbejde i 8 timer (jeg har ellers i min tid som arbejdsløs, dvs. de sidste 8 måneder, aktiveret mig selv en del og derfor tilrettelagt min kostplan efter dette kcal-forbrug).

I forbindelse med en revurdering af min kostplan, kom jeg til at tænke på, at jeg har et hæve/sænke-bord til rådighed. HVIS jeg nu står op hele dagen ved mit skrivebord, retfærdiggøre det så at bruge "stående arbejde/butiksarbejde" i ligevægtsberegneren...?

Dvs. det grundlæggende spørgsmål: Hvor meget ekstra forbrænder jeg ved at stå op ved et skrivebord kontra at sidde ned?

Jeg har kigget rundt omkring på nettet, og de få steder jeg har fundet, nævnes i omegnen af 200 kcal, mens andre er helt nede på 60 kcal.

Abstract

Background: We found recently that changes in nonexercise activity thermogenesis (NEAT) mediate resistance to weight gain with overfeeding in sedentary adults. A potentially important, yet seldom investigated, component of NEAT is the energy expenditure of fidgeting-like activities.

Objective: Our goal was to measure changes in energy expenditure with fidgeting-like activities.

Design: Energy expenditure was measured in 24 subjects (17 women and 7 men; x̄ ± SD body weight: 76 ± 21 kg) while recumbent at rest, sitting motionless, standing motionless, partaking of self-selected fidgeting-like movements while seated and while standing, and walking on a treadmill at 1.6, 3.2, and 4.8 km/h (1, 2, and 3 mph). Measurements were performed by using a high-precision, indirect calorimeter connected to the subject via a transparent, lightweight facemask that enabled almost unrestricted movement.

Results: Compared with metabolic rate in the supine position (5.4 ± 1.5 kJ/min), energy expenditure increased while sitting motionless by 4 ± 6%, while fidgeting while seated by 54 ± 29% (P < 0.0001), while standing motionless by 13 ± 8% (P < 0.0001), while fidgeting while standing by 94 ± 38% (P < 0.0001), while walking at 1.6 km/h by 154 ± 38% (P < 0.0001), while walking at 3.2 km/h by 202 ± 45% (P < 0.0001), and while walking at 4.8 km/h by 292 ± 81% (P < 0.0001). There was a significant, positive correlation between changes in energy expenditure and body weight for fidgeting-like activities while standing (r = 0.43, P = 0.02) but not while seated.

Conclusions: There is marked variance between subjects in the energy expenditure associated with self-selected fidgeting-like activities. The thermogenic potential of fidgeting-like and low-grade activities is sufficiently great to substantively contribute to energy balance.

Altså bruger du ca. 8 kJ/min ved at sidde ned og arbejde og ca. 11 kJ/min ved at stå op og arbejde.

Det virker sygeligt at en SÅ undervægtig person (188cm, 62kg, BMI <18) går op i den slags småting i stedet for at spise flere rugbrødsmadder.

Alle starter et sted.

Ja, alle starter et sted, men i det sted han er så er det da lidt tosset at gå op i kcal..

Helt enig.. Han skal bare spise alt det mad han kan få ned.

Jeg takker for linket til artiklen. Meget brugbart, og vel i overensstemmelse med de godt 200 kcal jeg selv havde fundet frem (en forksel på 3kj/min * 480 min = 1440 kJ / 4,2 = 342kcal. Det er da alligevel en significant forskel.

Mht. min vægt osv. så kom mit spørgsmål også som en generel undren, og samtidig kunne mange andre jo gøre brug af det. Samtidig, er det rart at vide, at jeg skal huske at indtage 300 kcal ekstra hvis jeg står op en dag

Desuden har jeg ikke noget problem med at spise nok - vil blot gerne prøve leangain-princippet af - ergo er en kostplan nødvendig :-)

Jeg takker igen for dit svar

Hvis jeg vil prøve lean gain princippet af, så tror jeg det er ganske ok at gå op i kcal. Samtidig har vi også kantine på arbejdet, og når man lige har været studerende, så er det en ganske fortræffelig arbejdsgode, at der nu er uanede mængder mad til rådighed :roll:

Jeg kunne let tage 1 kilo på / uge med min appetit og de mængder af mad der er til rådighed :lol:

Det er på ingen måde umuligt for mig at spise, men at holde vægtforøgelsen nede på 2-300 gr. /uge kræver imo en veltilrettelagt kostplan

Helt enig.. Han skal bare spise alt det mad han kan få ned.

Som jeg også har skrevet til de andre, så ville jeg - efter lean gain principppet - gaine alt for meget pr. uge hvis jeg spiste alt det jeg kunne få ned

Derfor ville jeg godt prøve at estimere mit kcal-forbrug i denne nye situation med ændrede arbejdsvaner
