Article Synopsis
- - This study reviews evidence from meta-analyses about how baseline cardiorespiratory fitness (CRF) relates to health outcomes, focusing on mortality and the incidence of chronic conditions in adults.
- - High CRF significantly lowers the risk of all-cause mortality (by about 53% comparing high with low levels) and is linked to an 11%-17% reduction in mortality for every additional MET of CRF.
- - The findings indicate that maintaining high CRF is beneficial for reducing risks of heart failure and cardiovascular-related deaths, though the overall quality of the evidence varies from low to moderate.
Background: Cardiorespiratory fitness (CRF) is an important indicator of current and future health. While the impact of habitual physical activity on CRF is well established, the role of sedentary behaviour (SB) remains less understood.
Objective: We aimed to determine the effect of SB on CRF.
Article Synopsis
- Built environments are linked to chronic diseases due to their influence on physical activity (PA), prompting a surge in research seeking to clarify this relationship.
- The study reviewed 116 systematic reviews focusing on the connections between built environments and various PA domains among adults in high-income OECD countries, finding most evidence to be of low quality.
- Results indicated moderate to high certainty that supportive environments enhance active transportation among working-aged adults, but there was limited evidence regarding older adults and occupational PA, with many findings remaining inconclusive.
Background: Built environments have shown to be associated with health, with physical activity (PA) considered one of the critical pathways for achieving benefits. Navigating available evidence on the built environment and PA is challenging given the number of reviews.
Objective: Examine the current state and quality of research looking at associations between built environments and total PA and domains of PA (i.
The effect of leisure time physical activity and sedentary behaviour on the health of workers with different occupational physical activity demands: a systematic review.

Background: Although it is generally accepted that physical activity reduces the risk for chronic non-communicable disease and mortality, accumulating evidence suggests that occupational physical activity (OPA) may not confer the same health benefits as leisure time physical activity (LTPA). It is also unclear if workers in high OPA jobs benefit from LTPA the same way as those in sedentary jobs. Our objective was to determine whether LTPA and leisure time sedentary behaviour (LTSB) confer the same health effects across occupations with different levels of OPA.
