“…[12][13][14][15] Authors have suggested that maintaining the lumbar lordosis has a protective effect on the structures of the spine in different postures. 16,17 In a study examining cadaver specimens, Farfan and colleagues 18 noted an association between decreased lumbar lordosis and disk degeneration at the L5/S1 intervertebral disk level. Furthermore, intradiskal pressure has been found to be inversely proportionate to the degree of lumbar lordosis.…”

“…Respiratory rate, tidal volume and minute ventilation showed higher values in the sitting position without support [23]. Lin showed that the slump position when sitting results in a decrease in spirometric variables, compared to a position maintaining the physiological spine curvature [24].…”

Szczygieł E, Zielonka K, Mętel S, Golec J. Musculo-skeletal and pulmonary effects of sitting position -a systematic review. Ann Agric Environ Med. 2017; 24(1): 8-12. doi: 10.5604/12321966.1227647 Abstract Introduction. Year after year, we spend an increasing amount of time in a sitting position. Often, we sit with poor posture, as indicated by numerous pain syndromes within the musculoskeletal system. Several reports confirm that body posture and the amount of time spent in a seated position have extensive implications for our health. Previous studies and a literature review suggest there is limited knowledge regarding an ergonomic sitting position. Objective. The aim of the study was to analyze the research relating to a proper sitting position and the consequences of incorrect sitting posture. A database search was conducted in Science Direct, Scopus, PubMed, Medline, and Google Scholar. Selection was made on the basis of titles, then abstracts and full texts of the studies. No limits were applied to the date of publication. Conclusions. Incorrect sitting posture contributes to many disorders, especially in the cervical and lumbar spine. It also determines the work of the respiratory system. Most authors suggest that maintenance of the physiological curvature of the spine is crucial for the biomechanics of the sitting position, as well as the location of the head and position of the pelvis. It raises awareness of work-related hazards and the introduction of education on the principles of proper seating. It is necessary to draw attention to the risks associated with work performed in a sitting posture, and education on the principles of ergonomical sitting.

“…Individuals who cannot functionally reposition themselves in long-term sitting adopt a passive body posture and often suffer from physical discomfort such as pressure ulcers (Collins, 1999), low back injury (Verver et al, 2003;Lengsfeld et al, 2000a;Lengsfeld et al, 2000b;Makhsous et al, 2003;van Deursen et al, 2000;Ferguson and Marras, 1997), respiratory dysfunction (Lin et al, 2006), lumbar immobility and joint stiffness (Beach et al, 2005).…”
