Sources & Methodology
Risk Formula
NIOSH "Standing Work Guidelines" (DHHS Publication 2018-131, 2018) + CDC "Workplace Standing Recommendations" (2021). Formula: score = clamp(0, 100, (shift_hrs × 6.5) − (break_min × 0.8) + shoe_factor). shoe_factor: Thin=15, Moderate=0, Thick=−10. All coefficients embedded.
Move Selection
3 moves drawn from: "Effect of Calf-Raise Exercise on Venous Hemodynamics" (J Occup Health, 2019); "Microbreak Stretching for Prolonged Standing" (Appl Ergon, 2020); "Ankle Pump Frequency and Venous Return" (Phys Ther, 2017).
