The specific aim of this study is to understand how a working day composed of prolonged sitting, sitting regularly interrupted by light aerobic exercise or resistance exercise affects an important mechanism underpinning healthy brain functions, namely cerebral blood flow. It is primarily focused on investigating these effects in ecologically valid conditions, i.e. activity patterns that closely resemble a typical day at the office.
The study will be a controlled crossover experimental trial with three conditions involving 26 adult participants aged between 40 and 60 years. Each participant will complete each of the three experimental conditions, separated by a washout period of minimum four days. As well, physical activity behaviours and sleep the day/night before the test day will be measured. The first visit will be a familiarization session. On the second, third, and fourth visits, participants will undergo three different standardized 3-hour interventions in a randomized order. Before and immediately after the three-hour interventions, blood pressure, augmentation index, and cerebral hemodynamic response of the prefrontal cortex during standardized cognitive tasks (1,2, and 3-back tests) will be measured. Additionally, saliva samples will be collected the morning of the test day and before and after the interventions, blood glucose will be assessed continuously during the trial, and fitness will be measured at the familiarization visit.

The primary aim of this study is to assess the feasibility of an intervention to reduce and break up prolonged sitting time in full-time police staff. The secondary aims of this study are ...
The effects of 12 hours of prolonged standing will be compared to prolonged standing on a high fat tolerance test the following day. Plasma triglycerides, insulin, and glucose will be meas...
The purpose of this project is to investigate the effect of breaking prolonged sitting on acute adipose tissue and metabolic responses.
Prolonged sitting has been shown to effect the response to a high fat tolerance test (HFTT) after acute exercise. This study will evaluate the effect of prolonged sitting on response to a ...
Over 3 million in the United Kingdom are now diagnosed with type 2 diabetes, with current estimates suggesting this will rise to over 5 million by 2025. Type 2 diabetes increases the risk ...
Prolonged sitting has been shown to promote endothelial dysfunction in the lower legs. Further, it has been reported that simple sitting-interruption strategies, including calf raises, prevent leg end...
Growing evidence suggests that prolonged uninterrupted sitting can be detrimental to health. Much sedentary behaviour research is reliant on self-reports of sitting time, and sitting-reduction interve...
The ActiGraph has a high ability to measure physical activity, however, it lacks an accurate posture classification to measure sedentary behaviour. The aim of the present study was to develop an ActiG...
High levels of sitting are associated with increased risk of adverse health outcomes, including chronic disease. Extensive sitting at work is common, hence organisations should provide options to empl...
There is increasing evidence that subjects who are exposed to long sitting periods suffer from musculoskeletal discomfort and back pain. The underlying mechanism and effective prevention strategies ar...
Therapy of sitting in a hot steamy room followed by a cool bath or shower.
A condition of the feet produced by prolonged exposure of the feet to water. Exposure for 48 hours or more to warm water causes tropical immersion foot or warm-water immersion foot common in Vietnam where troops were exposed to prolonged or repeated wading in paddy fields or streams. Trench foot results from prolonged exposure to cold, without actual freezing. It was common in trench warfare during World War I, when soldiers stood, sometimes for hours, in trenches with a few inches of cold water in them. (Andrews' Diseases of the Skin, 8th ed, p27)
A term used to describe pregnancies that exceed the upper limit of a normal gestational period. In humans, a prolonged pregnancy is defined as one that extends beyond 42 weeks (294 days) after the first day of the last menstrual period (MENSTRUATION), or birth with gestational age of 41 weeks or more.
One of three bones that make up the coxal bone of the pelvic girdle. In tetrapods, it is the part of the pelvis that projects backward on the ventral side, and in primates, it bears the weight of the sitting animal.
A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
