Upper-Extremity physical performance tests in older adults: Reference values, reliability and measurement error.
J Bodyw Mov Ther
October 2024
Background: Physical performance tests are reliable tools to assess aspects related to strength, power, and mobility. Unfortunately, few studies were performed with older adults. The main goal of this study was to describe reference values for the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and Upper Quarter Y Balance Test (UQYBT) in older adults and to determine differences based on sex.

- Researchers created smart films using starch, pectin, and purple carrot peel (PCP) that contain anthocyanins, enabling them to act as pH-responsive tags for monitoring plant-based chicken products.
- They tested different forms of PCP (powder and extracts) and found that films with higher PCP concentrations improved strength and water resistance while effectively responding to pH changes.
- The study demonstrated that these films changed color significantly over three days when used on chicken equivalents, highlighting PCP's potential as a natural colorant and indicator in food packaging.
The global food industry faces a critical challenge in ensuring sustainable practices to meet the demands of a growing population while minimizing environmental impact. At the same time, consumer awareness and the demand for quality products drive innovation and inspire positive changes in the food supply chain. Aiming to create a more sustainable and nutrient-rich alternative, this study is summarized by characterizing the physical and chemical characteristics of algae-enriched chickpea hummus: an innovative approach to popular food products.

January 2024
Background: Patellofemoral Pain (PFP) is one of the main injuries in runners. Consistent evidence support strengthening programs to modulate symptoms, however, few studies investigated the effects of gait retraining programs.
Objective: To investigate the effects of two different two-week partially supervised gait retraining programs on pain, function, and lower limb kinematics of runners with PFP.
Interaction of Biomechanical, Anthropometric, and Demographic Factors Associated with Patellofemoral Pain in Rearfoot Strike Runners: A Classification and Regression Tree Approach.
Sports Med Open
January 2024
Article Synopsis
- Patellofemoral pain (PFP) is a common injury in runners, and this study investigated how various factors interact to contribute to it using Classification and Regression Tree analysis.
- Runners with PFP showed distinct differences in biomechanics, such as higher braking ground reaction force and lower contact times compared to healthy controls, with the model successfully classifying 84.2% of PFP cases.
- The findings suggest that certain modifiable biomechanical factors could be key targets for future interventions to help prevent or manage PFP in runners.
