Background: Research has shown the effectiveness of sedentary behaviour interventions on reducing sedentary time. However, no systematic review has studied where the reduced sedentary time after such interventions is displaced to.
Objective: Our objective was to synthesize the evidence from interventions that have reduced sedentary behaviour and test the displacement of sedentary time into physical activity (light physical activity [LPA], moderate-to-vigorous physical activity [MVPA], standing, and stepping).
Methods: Two independent researchers performed a systematic search of the EBSCOhost, PubMed, Scopus, and Web of Science electronic databases. Meta-analyses were performed to examine the time reallocated from sedentary behaviour to physical activity during working time and the whole day in intervention trials (randomized/non-randomized controlled/non-controlled).
Results: A total of 36 studies met all the eligibility criteria and were included in the systematic review, with 26 studies included in the meta-analysis. Interventions showed a significant overall increase in worksite LPA (effect size [ES] 0.24; 95% confidence interval [CI] 0.05 to 0.43; P < 0.013) and daily LPA (ES 0.62; 95% CI 0.34 to 0.91; P = 0.001). A statistically significant increase in daily MVPA was observed (ES 0.47; 95% CI 0.26 to 0.67; P < 0.001). There was a significant overall increase in worksite standing time (ES 0.76; 95% CI 0.56 to 0.95; P < 0.001), daily standing time (ES 0.52; 95% CI 0.38 to 0.65; P < 0.001), and worksite stepping time (ES 0.12; 95% CI 0.04 to 0.20; P = 0.002).
Conclusions: Effective interventions aimed at reducing sedentary behaviour result in a consistent displacement of sedentary time to LPA and standing time, both at worksites and across the whole day, whereas changes in stepping time or MVPA are dependent on the intervention setting. Strategies to reduce sedentary behaviour should not be limited to worksite settings, and further efforts may be required to promote daily MVPA.

Introduction: Submarine environments pose unique challenges to maintaining physical activity and exercise routines due to confined spaces, demanding schedules, and limited resources. This study investigated submariners' physical activity patterns, sleep quality, and perceived exercise barriers in both land- and sea-based settings, with the goal of informing targeted health interventions.
Materials And Methods: Ethics approval was granted by the Defence Science and Technology Group and Edith Cowan University review panels.

Background: The effects of physical activity (PA), especially brisk walking, on labor outcomes and pregnancy health have not been clearly established. This study aimed to investigate the relationship between PA and cervical ripeness and pregnancy outcomes in term pregnant women.
Basic Procedures: A prospective cohort study was conducted with 52 pregnant women (30.

Purpose: To investigate the associations between different physical activity patterns, including "weekend warrior" (WW) (i.e. most weekly moderate-vigorous physical activity (MVPA) achieved over 1-2 days)) and regular (MVPA spread more evenly) patterns with the risk of incident cancers.

Physical activity (PA) is a fundamental aspect of preventive medicine, offering profound benefits for cardiovascular health and overall well-being. Despite its widespread benefits, the molecular mechanisms underlying PA-induced improvements in microvascular functions remain poorly understood. The skin microvasculature is uniquely affected by exercise-induced shear stress, especially during thermoregulation.

This study investigated the prospective associations between changes in 24-h movement behaviors and physical fitness (PF) components in preschool children; and examined how the reallocation of time between movement behaviours was associated with longitudinal changes in PF. This is a two-year longitudinal study of 200 Chinese children aged 3-4 years old. At baseline and follow-up, 24-h movement behaviors including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), screen-based sedentary behavior (SSB), non-screen-based sedentary behavior (NSB), and sleep were assessed.
