    This study assessed cardiovascular stress from static and dynamic tasks. Manual lifting showed lower oxygen consumption and heart rate than stepping, indicating different physiological fatigue criteria are needed for lifting standards.

    Area of Science:

    • Occupational health
    • Cardiovascular physiology
    • Ergonomics

    Background:

    • Cardiovascular stress is a key factor in occupational health and safety.
    • Understanding the physiological responses to different physical tasks is crucial for setting appropriate work standards.
    • Existing fatigue criteria may not be universally applicable across diverse manual tasks.

    Purpose of the Study:

    • To determine the cardiovascular stress effects of tasks with varying static and dynamic components.
    • To compare physiological responses (heart rate, oxygen consumption, blood pressure) during weight holding, manual lifting, and stepping.
    • To evaluate the suitability of current physiological fatigue criteria (PFC) for manual lifting tasks.

    Main Methods:

    • Measured heart rate, oxygen consumption, and blood pressure as indicators of cardiovascular stress.

  • Assessed tasks including weight holding, manual lifting (differentiated by frequency), and stepping.
  • Analyzed physiological data to compare stress responses across different task types.

    • Main Results:

    • Oxygen consumption and heart rate were lower during manual lifting compared to stepping, but higher than during weight holding.
    • Low-frequency manual lifting resulted in significantly lower systolic blood pressure than high-frequency lifting.
    • Stepping tasks elicited higher cardiovascular stress than manual lifting tasks.

    Conclusions:

    • A physiological fatigue criterion (PFC) based solely on stepping is not directly applicable to manual lifting.
    • Manual lifting standards should incorporate systolic blood pressure, in addition to oxygen consumption and heart rate, for a comprehensive PFC.
    • Task-specific physiological monitoring is essential for accurate occupational safety standards.
