Abstract
Ievads. Attīstoties mūsdienu pasaulei un darba procesu digitalizācijai, aizvien vairāk profesionāļu savā ikdienas darbā izmanto datorus. COVID-19 pandēmija arī ir pierādījusi, ka lielākā daļa profesiju pārstāvju, skolēnu un studentu spēj pildīt savus pienākumus no mājām. 2021. gadā Eiropas Savienībā 58% no visiem profesiju pārstāvjiem ikdienas darba pienākumu veikšanai izmantoja datoru [1]. Zinātniski pierādīts, ka ilgstoša sēdēšana ikdienā ir riska faktors muskuloskeletālu, kardiovaskulāru un metabolu slimību attīstībai [2]. Sēdošs darbs ir statiska slodze, kas izraisa muskuļu izotonisku kontrakciju un rada straujāku muskuļu nogurumu un papildus noslogo apkārt esošos audus [3]. Sabiedrības veselības pārstāvji vēljoprojām strādā pie labākas metodes, kā samazināt sēdoša darba ietekmi uz veselību un aktualizē “aktīvo sēdēšanu”[4].
Darba mērķis. Noskaidrot, vai vingrošanas bumbas izmantošana parasta krēsla vietā, ilgstoši strādājot ar datoru, samazina plaukstas virsmas temperatūras krišanos.
Materiāls un metodes. Četriem veseliem brīvprātīgajiem, trīs stundas nepārtraukti strādājot ar datoru, ik 15 minūtes tika uzņemti termogrāfiski attēli labās rokas virsmai, sēžot uz parastā krēsla vai vingrošanas bumbas. Darba izstrādei tika izmantota augstas izšķirtspējas medicīniskā digitālā termogrāfijas kamera ICI ETI 7320 Pro, specializēta attēlu apstrādes programma IR Flash Medical Version 12 2.14.14.4 un 3 ass akselerometrs Axivity AX6. Datu analīze tika veikta MS Excel un IBM SPSS Statistics datorprogrammās.
Rezultāti. Visiem brīvprātīgajiem, neatkarīgi no sēdvietas veida, ilgstoši strādājot ar datoru, tika novērota labās rokas plaukstas virsmas temperatūras samazināšanās. Tika novērota vidēji cieša negatīva korelācija starp labās rokas plaukstas virsmas temperatūru un laiku (rs = - 0,543, p < 0,001), pavadītu sēžot uz parastā krēsla. Sēžot uz vingrošanas bumbas, tika novērota ļoti cieša negatīva korelācija starp plaukstas virsmas temperatūru un laiku (rs = - 0,866, p < 0,001). Viszemākā vidējā plaukstas virsmas temperatūra, kas tika novērota pētījuma laikā, ir 17,49°C, 3 stundas sēžot uz vingrošanas bumbas un strādājot ar datoru, kas ir par 5,51°C grādiem zemākā, nekā gaisa temperatūra eksperimenta laikā (23,1°C). Netika novērota statistiski nozīmīga atšķirība vidējā kustību amplitūdā starp parasto krēslu un vingrošanas bumbu.
Secinājumi. Ilgstošs darbs ar datoru izraisa plaukstas virsmas temperatūras krišanos neatkarīgi no sēdvietas veida. Sēdēšana uz vingrošanas bumbas neuzlaboja rokas mikrocirkulāciju un temperatūras noturīgumu.
Introduction. With the development of the modern world and the digitalisation of work processes, more and more professionals use computers in their daily work. The COVID-19 pandemic has also shown that the majority of professionals, pupils and students are able to carry out their duties from home. By 2021, 58% of all professionals in the European Union used a computer to carry out their daily work duties [1]. Prolonged sedentary position has been scientifically proven to be a risk factor for the development of musculoskeletal, cardiovascular and metabolic diseases [2]. Sedentary work is a static load that causes isotonic contraction of muscles and cause fatigue in the muscles and put additional strain on the surrounding tissues [3]. Public health representatives are still working on better ways to reduce sedentary work’s negative effects on health and to promote “active sitting” [4]. The aim of this work was to determine whether the use of an exercise ball instead of a standard chair during prolonged computer work reduces the decline in hand surface temperature. Material and methods. Four healthy volunteers were working continuously on a computer for three hours, every 15 minutes thermographic images were taken of the right hand while seated on a standard chair and an exercise ball. The ICI ETI 7320 Pro high-resolution medical digital thermography camera, IR Flash Medical Version 12 2.14.14.4 and Axivity AX6 3-axis accelerometer were used to develop the work. Data analysis was performed in MS Excel and IBM SPSS Statistics computer programs. Results. In all volunteers, regardless of the seat type, prolonged computer use resulted in a decrease in right hand surface temperature. There was a moderately strong negative correlation between right hand surface temperature and time (rs = - 0.543, p <0.001) spent sitting on a standard chair. A very strong negative correlation between hand surface temperature and time (rs = - 0.866, p <0.001) was observed while sitting on an exercise ball. The lowest mean hand surface temperature observed during the study was 17.49 °C, sitting on an exercise ball for 3 hours and working with a computer, which is 5.51 ° C lower than the air temperature during the experiment (23.1 °C). There was no statistically significant difference in mean movement intensity comparing volunteers sitting on a standard chair or an exercise ball. Conclusions. Prolonged work with a computer causes a decrease in the temperature of the hand surface, regardless of the seat type. Sitting on an exercise ball did not improve hand microcirculation and did not reduce temperature decline of the right hand surface.
