Article Abstract
Objective: To develop the physical activity questionnaire for Chinese children aged 6-17 years old, in order to evaluate the children's physical activity.
Methods: After systematic review, expert review and preliminary investigation, the "6-to 17-year-old Chinese children physical activity questionnaire(CCPAQ)" was established to measure the weekly physical activity. Based on the sample size estimation and inclusion and exclusion criteria, 120 children aged 6-17 were selected from one survey site in the south and north of China. SAS 9.4 software and Mplus 8.0 software were used for factor analyses to validate the modes and types of physical activity measured by CCPAQ.
Results: This study included 119 subjects in total. Exploratory factor analyses were used to assess the 33 modes and 7 types of physical activity time and extract four and one common factor, respectively. Confirmatory factor analysis fitted a second-order 4 factors model and first-order 7 factors model. The evaluation index of the two models were χ~2/df=1.41 and χ~2/df=1.61, respectively, showing that the models fitting were acceptable.
Conclusion: CCPAQ established in this study can effectively measure the physical activity of Chinese children aged 6-17 years.

Unlabelled: Despite stimulating glucagon secretion, the mechanisms by which protein ingestion lowers glucose excursions remain unclear. We investigated this using the triple stable isotope glucose tracer technique to measure postprandial glucose fluxes. Eleven healthy adults completed three trials, ingesting 25 g glucose (25G; 100 kcal), 50 g glucose (50G; 200 kcal), or 25 g glucose plus 25 g whey protein (25WG; 200 kcal).

Importance: Cannabis is the most commonly used illicit drug, with 10% to 30% of regular users developing cannabis use disorder (CUD), a condition linked to altered hippocampal integrity. Evidence suggests high-intensity interval training (HIIT) enhances hippocampal structure and function, with this form of physical exercise potentially mitigating CUD-related cognitive and mental health impairments.
Objective: To determine the impact of a 12-week HIIT intervention on hippocampal integrity (ie, structure, connectivity, biochemistry) compared with 12 weeks of strength and resistance (SR) training in CUD.
Background: People with dementia who have a fall can experience both physical and psychological effects, often leading to diminished independence. Falls impose economic costs on the healthcare system. Despite elevated fall risks in dementia populations, evidence supporting effective home-based interventions remains limited.

Parkinson's disease (PD) is characterized by impairments in motor control following the degeneration of dopamine-producing neurons located in the substantia nigra pars compacta. Environmental pesticides such as Paraquat (PQ) and Maneb (MB) contribute to the onset of PD by inducing oxidative stress (OS). This study evaluated the therapeutic efficacy of moderate physical activity (PA) on both motor and non-motor symptoms in a Wistar rat model of Paraquat and Maneb (PQ/MB) induced PD.

Engaging residents with the support available at community-based residential mental health rehabilitation facilities is an ongoing challenge for health services. This study explored factors associated with residential rehabilitation engagement across Queensland, Australia through regression modelling of cross-sectional data from a statewide benchmarking activity completed in 2023 (n = 208). The Residential Rehabilitation Engagement Scale (RRES) assessed each resident's rehabilitation engagement.
