  • The study aimed to assess the effectiveness of a UK-based prediction model for estimating fat-free mass in children and adolescents across 19 countries outside the UK.
  • Involving 5,693 participants aged 4 to 15, the model exhibited strong predictive performance, with R values over 75% in all countries and good calibration of predicted versus actual fat-free mass.
  • The researchers found minimal variation in model performance based on gender, age, ethnicity, or national income, and they adjusted the model for different countries to enhance accuracy for future use.

  • * A total of 56 studies were analyzed, revealing that the Medial Tibial Stress Syndrome Score (MTSSS), Lower Extremity Functional Scale (LEFS), and Exercise-Induced Leg Pain Questionnaire (EILP-Q) were the primary PROMs for EILP, with the Visual Analog Scale (VAS) being the most frequently used.
  • * Evaluation of the PROMs' psychometric properties revealed that while the overall quality was low, the LEFS outperformed the others in quality assessments, followed by the MTSSS and

Background: Pulse wave velocity (PWV) independently predicts cardiovascular risk. Easy to use single-cuff oscillometric methods are utilized in clinical practice to estimate PWV. We applied the approach in master athletes to assess possible beneficial effects of lifelong exercise on vascular health.
