Jalkalihaksista tutkittiin lihasaktiivisuuden kannalta seuraavia lihaksia: m.rectus femoris (suora reisilihas), m.vastus lateralis (ulompi reisilihas), m.biceps femoris (kaksip\u00e4inen reisilihas), m.tiabialis anterior (etummainen s\u00e4\u00e4rilihas), m.gastrognemius (kaksoiskantalihas), m.soleus (leve\u00e4 kantalihas).

The effects of different office chairs on leg swelling and leg`s muscle activity. The Department of Biology of Physical Activity, University of Jyv\u00e4skyl\u00e4, Master\u2019s thesis, 56 pp., 7 appendices.\r\nAs we start using computers more and more on a daily basis, it\u2019s affecting our health. In sitting position the blood flow in legs decreases and legs will swell.\r\nIn this master\u2019s thesis, the effects of sitting on two different office chairs (a common static chair and a dynamic saddle chair) on leg muscle activity and swelling were observed and compared. Muscle activity was measured from the following muscles: m. vastus lateralis, m. rectus femoris, m. biceps femoris, m. tibialis anterior, m. gastrognemius and m. soleus. An additional objective was to assess the possible correlation between muscle activities in legs and the extent of leg swelling during the sitting period.\r\n To measure the leg\u2019s muscle activity, surface electromyography (sEMG) was used. Water displacement volumetry (WDV) technique was used to measure the leg\u2019s swelling. There were twelve subjects and each participated in the measurements on two mornings. Subjects sat for two hours on either a common office chair or on a saddle chair and mostly worked on a computer. Order of the chairs was randomised. Before and after the sitting period, the subject\u2019s leg\u2019s volume was measured in a water container. Right after the sitting period, the subjects answered to an inquiry about the comfort level of the chair types used.\r\nAfter two hours of sitting, swelling in legs occurred in both chair types (average on saddle chair was 166 \u00b1 50 ml and on a common chair 125 \u00b1 47 ml). The amount of swelling on a saddle chair was significantly bigger than on a common chair (p < 0, 05). The differences in muscle activities were statistically insignificant, although the muscle activity was slightly higher on the saddle chair. Subjects did not feel much difference between the chair\u2019s comfort levels. In this study, no clear associations between leg\u2019s muscle activity and swell-ing were found. The type of chair affected the amount of swelling; sitting on the saddle chair causes more swelling. Although dynamic saddle chair allows higher leg activity, but in this study the subjects did not seem to use these chair\u2019s features during computer work and sat statically.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Malle Haas (mahaas) on 2015-04-16 06:53:02.565120.
