Associations between lifestyle and well-being in early and late pregnancy in women with overweight or obesity: Secondary analyses of the PEARS RCT.

Objectives: The associations between individual lifestyle behaviours and well-being are still poorly understood, particularly in the antenatal period when women are exposed to physiological changes and increased psychological distress. A healthy lifestyle score (HLS) comprising protective lifestyle behaviours may be useful for studying links between overall lifestyle and psychosocial outcomes. This study aimed to examine bidirectional associations between a HLS and its components and psychological well-being in pregnant women with overweight/obesity.

Assessing pre-season workload variation in professional rugby union players by comparing three acute:Chronic workload ratio models based on playing positions.

Quantifying the pre-season workload of professional Rugby Union players, in relation to their respective positions not only provides crucial insights into their physical demands and training needs but also underscores the significance of the acute:chronic workload ratio (ACWR) in assessing workload. However, given the diversity in ACWR calculation methods, their applicability requires further exploration. As a result, this study aims to analyze the workload depending on the player's positions and to compare three ACWR calculation methods.

Why do preconception and pregnancy lifestyle interventions demonstrate limited success in preventing overweight and obesity in children? A scoping review investigating intervention complexity, process evaluation components, and author interpretations.

Preventing childhood obesity from early life is considered essential. However, evidence from recent systematic reviews has highlighted inconsistent results and limited effectiveness of preconception and pregnancy lifestyle interventions regarding offspring weight outcomes and adiposity. Therefore, to improve our understanding regarding the mixed success of these early life interventions, we conducted a scoping review examining intervention complexity, process evaluation components, and authors' statements.

Position-specific workload of professional rugby union players during tactical periodization training.

The positional workload characteristics in rugby union on three acquisition days (i.e. strength, endurance, and speed days) of tactical periodization are still relatively unknown.
