In Asia, many activities of daily living (ADL) are performed while sitting cross-legged on the floor. This sitting posture rotates the pelvis in a more dorsal direction and lumbar lordosis is more flattened than while sitting on a chair. Sitting cross-legged induces a greater load on the intervertebral discs and spine, especially when in a slumped position that is known to increase disc pressur...

An earlier study suggested that the activity-inviting office landscape called "The End of Sitting", designed by Rietveld Architecture Art Affordances (RAAAF), should be considered as an alternative working environment to prevent sedentary behavior. The End of Sitting lacks chairs and tables but consists instead of a myriad of sloped surfaces at different heights that afford workers to stand, le...

In this study, we evaluated the influence of idiopathic scoliosis on postural balance and muscle activity in static and dynamic sitting condition. Twelve adolescents with idiopathic scoliosis were included in this study. Postural balance and muscle activities of all subjects were assessed under two experimental conditions: i) static sitting, ii) dynamic sitting. In static sitting condition, sub...

BACKGROUND Physical inactivity and prolonged sitting are associated with negative health outcomes. PURPOSE To examine the health-related costs of prolonged sitting and inactivity in middle-aged women. METHODS Australian Longitudinal Study on Women's Health participants (born 1946-1951) answered questions about time spent sitting, walking, and in moderate and vigorous leisure activities in 2...

OBJECTIVES Sitting time is a public health concern. This study examined associations of objectively measured neighbourhood environmental attributes with non-transport sitting time and motorised transport in 484 Hong Kong older adults. Neighbourhood attributes encouraging walking may help older adults replace some sitting time at home and on motorised transport with light-to-moderate-intensity a...

STUDY DESIGN A prospective study was conducted on a group of patients with unilateral nonspecific low back pain (LBP) and healthy controls. OBJECTIVES To answer 3 questions: (1) Does pelvic asymmetry measured in standing affect the dynamics of motion performed in sitting? (2) Do patients with LBP perform trunk motions differently from non-LBP participants in sitting position? and (3) Do the k...

BACKGROUND Prolonged sitting is prevalent in the workplace and is associated with adverse health markers. PURPOSE Investigate the effects of point-of-choice (PoC) prompting software, on the computer used at work (PC), to reduce long uninterrupted sedentary periods and total sedentary time at work. DESIGN Assessor-blinded, parallel group, active-controlled randomized trial. SETTING/PARTICI...

BACKGROUND Epidemiological studies suggest that excessive sitting time is associated with increased health risk, independent of the performance of exercise. We hypothesized that a daily bout of exercise cannot compensate the negative effects of inactivity during the rest of the day on insulin sensitivity and plasma lipids. METHODOLOGY/PRINCIPAL FINDINGS Eighteen healthy subjects, age 21±2 yea...
