Background Persistent or recurrent neck pain is associated with perturbations in the autonomic nervous system balance, and nociceptive stimulation has been seen to influence this balance. However, very few prospective studies have addressed the extent to which changes in pain associate with changes in autonomic cardiac regulation. Therefore, we inv...
Article
Full-text available
Background Sick leave due to musculoskeletal pain is common in the workforce. Time use in physical behaviors at work such as sitting, standing, low- (LIPA) and moderate-to-vigorous physical activity (MVPA) may impact on sick leave due to pain. However, studies addressing this relationship using technical measures of physical behaviors are scarce. T...
Article
Full-text available
Background During the COVID-19 pandemic, many white-collar workers were requested to exclusively work from home (WFH), which may have affected their sedentary behavior. In Sweden, having less severe restrictions than many other countries, workers were allowed to alternate between WFH and work at the office (WAO), so called hybrid work. Understandin...
Article
Full-text available
Background In contrast to leisure time physical activity (LTPA), occupational physical activity (OPA) does not have similar beneficial health effects. These differential health effects, also known as the physical activity health paradox, might be explained by dissimilar effects of LTPA and OPA on cardiorespiratory fitness (CRF). This study aims to...
Article
Full-text available
Background ‘Sit less-move more' has been a common advice to improve health of adults. Research indicates that this advice might be health enhancing among adults with sedentary occupations but not among adults with physically active occupations such as cleaners. This may be explained by the considerable differences in 24-h physical behaviors between...
Article
Full-text available
There is strong and consistent evidence that leisure-time physical activity (LTPA) improves cardiovascular health and reduces the risk of all-cause and cardiovascular mortality. Less is known about health effects of occupational physical activity (OPA), and results are not in favor of a beneficial effect on cardiovascular health. Several large-scal...
Article
Full-text available
Background Physical activity is a key determinant for health and considered as an important factor in the prevention of lifestyle related-diseases. All physical activity domains are generally considered to be health enhancing. However, accumulating evidence in recent years suggests that occupational physical activity may not have the same beneficia...
