Was it a HIIT? A process evaluation of a school-based high-intensity interval training intervention.

Background: Despite a growing body of research investigating high-intensity interval training (HIIT) in schools, there are limited process evaluations investigating their implementation. This is concerning because process evaluations are important for appropriately interpreting outcome findings and augmenting intervention design. This manuscript presents a process evaluation of Making a HIIT, a school-based HIIT intervention.

Before-school physical activity patterns among adolescents using accelerometer and GPS data.

Most adolescents do not meet physical activity (PA) guidelines. The before-school segment has been identified as one promising opportunity for intervention; however, there is a need for contextual understanding of PA in this segment. This study aimed to examine: a) adolescents' PA levels across various locations before school (6:00am - school start), b) contributions of before-school PA to daily PA and PA guidelines, and c) correlates of location-specific before-school PA.

Before-school physical activity levels and sociodemographic correlates among Australian adolescents: A cross-sectional study.

Understanding adolescents' physical activity levels and underpinning contextual factors is crucial for health promotion. This cross-sectional study, using 24-hour time use diaries and sociodemographic variables from the , addressed gaps in understanding of physical activity in the before-school segment (the time between waking up and commencing classes). The study examined ) adolescents' time spent in before-school physical activity, focusing on location and shared presence, and ) sociodemographic correlates of before-school physical activity.

A qualitative exploration of multi-stakeholder perspectives of before-school physical activity.

Background: Engagement in before-school physical activity can potentially enhance health and learning-related outcomes for children and adolescents. However, influencing factors and stakeholder perceptions of before-school physical activity remain under-researched. This qualitative study aimed to examine stakeholder perceptions of: a) the suitability of the before-school segment for physical activity, b) barriers and facilitators associated with before-school physical activity, and c) strategies for schools to support before-school physical activity.

Perspectives of health professionals on physical activity and sedentary behaviour in hospitalised adults: A systematic review and thematic synthesis.

Objective: To explore health professionals' perspectives on physical activity and sedentary behaviour of hospitalised adults to understand factors that contribute to these behaviours in this environment.

Data Sources: Five databases (PubMed, MEDLINE, Embase, PsycINFO and CINAHL) were searched in March 2023.

Review Methods: Thematic synthesis.

School physical activity policies and associations with physical activity practices and behaviours: A systematic review of the literature.

The development and implementation of school policies is considered a key strategy for the promotion of physical activity (PA) in children and adolescents. This study aimed to systematically review and synthesise existing literature focusing on the associations between formal written school-based PA policies and (a) school PA practices and (b) PA behaviours of school-aged children and adolescents. Fifty-one papers reporting on 52 studies met the eligibility criteria.

Effects of school-based before-school physical activity programmes on children's physical activity levels, health and learning-related outcomes: a systematic review.

Objective: To review and evaluate the impact of school-based, before-school physical activity (PA) programmes on children's PA levels, health and learning-related outcomes.

Design: Systematic review.

Data Sources: PubMed, PsycINFO, Scopus, Embase and ERIC were searched in January 2021.
