Article Synopsis
  • - This study explores a new automated method for assessing sprint performance using machine learning and data from accelerometers worn by athletes during sprints, aiming to estimate key sprint metrics (maximal velocity and time to reach that velocity).
  • - Researchers recorded the sprint times of 28 subjects over three 40-meter sprints and trained a classifier to help identify the sprint start while also developing regression models to estimate performance parameters.
  • - The automated method showed a small error margin in estimating sprint times compared to traditional methods, indicating the potential benefits of combining both approaches for improved performance assessment.

Phospholipase D (PLD) has been implicated in mitotic regulation and has been shown to be defective in cells following replicative senescence. We examined the source of changes in PLD activity in senescent human umbilical vein endothelial cells and in human diploid fibroblasts. Using fractionated cell components we found that the cytosolic components were necessary for maximum PLD activation.

Background: Anecdotal and experimental evidence suggest that a sitting position with maximum knee extension, hip adduction, and forward lean (hamstring stretch position) may produce better reversal of the lumbar lordosis than a traditional sitting position.

Methods: In a randomized trial during initiation of epidural labor analgesia, we compared the traditional versus hamstring stretch positions. The primary outcome was the number of needle-bone contacts.
