Article Synopsis
- Smartphone applications (SPA) can effectively monitor health markers like body mass and fat percentage in a home setting, showing promise for personal weight loss management.
- Previous studies confirmed these apps have good accuracy, and this research tested their effectiveness over time with 38 participants.
- Comparisons between SPA estimates and professional measurements showed small differences and moderate agreement, highlighting the app's accessibility and cost-effectiveness, although it's not a complete substitute for high-accuracy medical methods.
Objective: Indonesia's dramatic rise in chronic disease belies their relatively low obesity prevalence. This study provides normative iDXA and anthropometry measures in an Indonesian cohort. We also compare obesity prevalence determined by traditional measures.

- The study aims to establish reference values for visceral adipose tissue (VAT) mass measured by DXA in a cohort of 677 men and 738 women aged 18-65 from Western Australia.
- High correlations between VAT mass and waist circumference were found in men, while in women, only the waist-height ratio showed a strong correlation.
- The research provides the first reference data for DXA-derived VAT mass in Western Australians and identifies anthropometric measures that can effectively detect excessive VAT mass in both genders.
By failing to prepare, you are preparing your anterior cruciate ligament to fail.

There is strong evidence linking an athlete's movement technique during sidestepping with anterior cruciate ligament (ACL) injury risk. However, it is unclear how these injurious postures are influenced by prior movement. We aim to describe preparatory trunk and thigh kinematics at toe-off of the penultimate-step and flight-phase angular momenta, and explore their associations with frontal-plane risk factors during unplanned sidestepping maneuvers.

This study aimed to compare statistical output and injury risk interpretation differences from two statistical regression models built from a clinical movement sidestepping database. A "naïve" regression model, which does not account for within-participant effects, was compared with an appropriately applied mixed effects model.

Female community-level team sport athletes, split into intervention (n = 8) and comparison groups (n = 10), completed a sidestepping movement assessment prior to and following a 9-week training period, in which kinetic, kinematic and neuromuscular data were collected. The intervention group completed a biomechanically informed training protocol, consisting of plyometric, resistance and balance exercises, adjunct to normal training, for 15-20 min twice a week.
