    This study found that carrying loads with one hand significantly reduces maximum acceptable load (MAL) compared to two-handed methods. Gait analysis revealed that most load carriage strategies alter walking speed, stride length, and cadence, highlighting the impact of carrying methods on locomotion.

    Area of Science:

    • Biomechanics
    • Ergonomics
    • Human Movement Science

    Background:

    • Load carriage significantly impacts human locomotion and physical exertion.
    • Understanding the relationship between load carriage strategies and gait parameters is crucial for preventing injuries and optimizing performance.
    • Existing literature presents conflicting findings on the effects of load carriage on gait.

    Purpose of the Study:

    • To assess the reliability of psychophysical methods for determining maximum acceptable loads (MAL).
    • To evaluate the reliability of selected gait parameters in describing locomotor patterns during load carriage.
    • To describe and compare locomotor patterns across various hand-and-arm load carriage strategies.

    Main Methods:

    • Employed a test-retest experimental design with ten male participants.

  • Determined MAL using modified Snook et al. (1970) procedures.
  • Measured gait parameters (walking speed, stride length, cadence, support periods) using footswitch technology (Wall et al., 1981).

    • Main Results:

    • Procedures for MAL and gait parameter assessment demonstrated high test-retest reliability.
    • One-hand carriage resulted in significantly lower MAL compared to two-handed methods.
    • Load carriage altered walking speed, stride length, and/or cadence, with varying effects across conditions.

    Conclusions:

    • The employed methods for assessing MAL and gait parameters are reliable.
    • Load carriage significantly affects locomotor patterns, with one-handed carrying being particularly limiting.
    • Discrepancies in literature may stem from variations in task and subject characteristics.
