Identifying salivary biomarkers associated with prolonged sitting
The effect of prolonged sitting on salivary biomarker concentrations is relatively unexplored. The purpose of this work was to identify novel biomarkers, detectable in the saliva in response to prolonged and interrupted bouts of sitting. Participants completed three sessions. The first session …

The effects of prolonged standing compared to prolonged sitting on postprandial lipemia
Prolonged periods of sedentary behavior are linked to cardiometabolic disease independent of many risk factors including exercise and activity levels. This study examined the effects of posture, rather than activity by comparing one full day of sitting (14.45 ± 0.286 hours) compared to one full day …

Impact of Prolonged Sitting on Cognitive Function: Implications for Cardio-metabolic Risk
<p><strong>Purpose: </strong>To determine if prolonged sitting negatively impacts cognitive function, cerebral perfusion, and central cardiovascular hemodynamics; and secondly, to test whether weight or physical activity status alters this response. <strong>Methods:</strong> Participants (N=20, …

Impact of Prolonged Sitting on Central Hemodynamics: Role of Intermittent Pneumatic Compression Therapy
<p>Prolonged sitting (3-6 hours) negatively impacts peripheral vascular health. Whether sitting similarly impacts central cardiovascular hemodynamics and vascular stiffness is unknown. <strong>Purpose: </strong>Determine if prolonged sitting increases central blood pressure, aortic pulse wave …

Influence of Prolonged Sitting and Psychosocial Stress on Lumbar Spine Kinematics, Kinetics, Discomfort, and Muscle Fatigue
… disability. Among diverse known risk factors, sitting is commonly considered as an important exposure related to LBP. Both modern living and contemporary work involve increased sedentary lifestyles, including more frequent and prolonged sitting. At present, however, the causal role of sitting …

Intermittent Standing and Prior Exercise as Strategies to Prevent Arterial Stiffening That Can Arise From Prolonged Sitting
<p>Prolonged sitting can cause adverse vascular responses, including elevations in aortic stiffness which might contribute to cardiovascular disease (CVD). Few studies have investigated the impact of intermittent standing and/or prior exercise as strategies to mitigate these deleterious vascular …

Response of salivary IL-8 to prolonged and interrupted sitting
The effect of prolonged sitting on inflammation, as determined by cytokine profiles, is relatively unexplored. The purpose of this work was to determine the reliability of salivary IL-8 (CXCL8) and the response of IL-8 to prolonged and interrupted sitting. Participants completed two sessions in …

The effects of sitting on cerebrovascular and cognitive function
… of this thesis were to explore the effects of sitting on cerebrovascular function, cognition and mood and to explore the effect of breaking up sitting on these parameters. Study one assessed whether objectively measured workplace sitting and PA were associated with cognition and mood. Results …

Comparison of electrical activity of lateral and medial stabilizers of the patella and further diagnostically relevant risk factors in athletes with and without patellofemoral pain and in a Tai Chi group
… as running, squatting, going up and down stairs, prolonged sitting, cycling, and jumping. Some of risk factors in athletes with PFPS were considered and compared with athletes without PFPS in the present study. In addition, since Tai Chi (TC) helps or reduces the load on the lower limbs joints, …

Using non-targeted mass spectrometry to identify proteomic, metabolomic and lipidomic profiles in saliva to compare the impact of prolonged vs. interrupted sitting
… involved 24 participants that engaged in both a prolonged sitting session and an interrupted sitting session, in a randomized order. Saliva samples were collected before and after each session, including a separate baseline. Samples were purified and concentrated then analyzed on the LC-MS. A …

Long driving hours and health of truck drivers
… sleep disorders and psychological distress. Prolonged sitting, whole-body vibration, physical and psychological fatigues were found to be the main risk factors that are related to the occupational health problems of truck drivers. These occupational risk factors were analyzed in detail to …

What significance does physical activity and sedentary behaviour have for members of online health promoting communities? Learning from AustraIia’s HeartNET community
… to consider developing strategies to reduce prolonged sitting time and encourage healthier behaviours. Follow-up studies are needed to determine the sustainability and applicability of my conclusions and recommendations in emerging online communities, where smartphones and ‘apps’ are the …

Increasing Physical Activity in Omani Adult Patients with Type 2 Diabetes Attending Primary Health Care Facilities, MUSCAT
… reported low levels of physical activity and prolonged sitting time in adults with type 2 diabetes. The odds of meeting PA recommendations were significantly greater in males, individuals ≤57 years, individuals reporting active stages of PA and those with no reported barriers to PA. ‘Lack of …

CARDIOVASCULAR CONSEQUENCES AFTER SPINAL CORD INJURY AND THE EFFECTS OF ELECTRICAL STIMULATION
… resulting from poor microvascular perfusion and prolonged sitting pressure. This, along with the findings from Chapter 4, provide a compelling rationale for studies to examine the long-term effects of low-level ES on the vasculature, pressure ulcer risk factors, and the feasibility of home based …
