Systematic review of the use of "magnitude-based inference" in sports science and medicine.

Magnitude-based inference (MBI) is a controversial statistical method that has been used in hundreds of papers in sports science despite criticism from statisticians. To better understand how this method has been applied in practice, we systematically reviewed 232 papers that used MBI. We extracted data on study design, sample size, and choice of MBI settings and parameters.

Light physical activity is positively associated with cognitive performance in older community dwelling adults.

Objectives: To evaluate the associations between an objective measure of different intensities of physical activity, upper- and lower-limb muscle strength and psychomotor performance and set-shifting domains of cognitive executive function in older adults.

Design: A cross-sectional study.

Methods: From the Tasmanian Older Adult Cohort Study, 188 community-dwelling older adults (53.

Fundamental Movement Skills Are More than Run, Throw and Catch: The Role of Stability Skills.

Introduction: In motor development literature fundamental movement skills are divided into three constructs: locomotive, object control and stability skills. Most fundamental movement skills research has focused on children's competency in locomotor and object control skills. The first aim of this study was to validate a test battery to assess the construct of stability skills, in children aged 6 to 10 (M age = 8.

Assessing motor imagery using the hand rotation task: does performance change across childhood?

This study examined at what age children can engage in the hand rotation task (as a measure of motor imagery); whether engagement changes across development and; the influence of age and motor skill on performance. Children were aged 5-12 years (N=101; 52 girls), with no IQ or motor skill impairment. Less than 40% of 5-6 year olds completed the hand rotation with sufficient accuracy for further analysis, compared with 80% of 7-8 year olds, and 90% aged 9 and above.

Examining the role of parental self-regulation in family physical activity: a mixed-methods approach.

Physical activity (PA) is essential for good health. However, parents risk becoming less active because of the demands of parenting. This has consequences for children as parents are role models.
