Prolonged occupational use of high-powered motorcycles leads to substantial muscle discomfort, particularly in the lower back and hands, with cumulative riding hours being a primary driver. This human factors research insight is drawn from a 2020 study published in Malaysian Journal of Public Health Medicine. Using Cross-sectional study with 137 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must prioritize ergonomic solutions that address prolonged static postures and repetitive strain, particularly for occupational users, by incorporating adjustable features and supportive elements.

Key Findings

  • 01Lower back (left and right) reported the highest mean discomfort (56.6 mm and 55.9 mm respectively).
  • 02Right and left upper back, and right hand also showed high discomfort ratings (around 47-48.5 mm).
  • 03Overall discomfort ratings for all regions averaged over 20 mm.
  • 04Strong positive correlation between cumulative riding hours and overall discomfort (r=0.785).
  • 05Moderate positive correlation between years of riding experience and overall discomfort (r=0.410).

Application

Design takeaway

Designers must prioritize ergonomic solutions that address prolonged static postures and repetitive strain, particularly for occupational users, by incorporating adjustable features and supportive elements.

How to apply

When designing any vehicle or equipment intended for prolonged or occupational use, conduct user research to identify common discomfort points and integrate ergonomic features to mitigate them.

Project actions

  • 01Investigate the anthropometrics of your target user group.
  • 02Consider the duration and frequency of product use in your design.
  • 03Use surveys or interviews to gather qualitative data on user discomfort.
03

Method & Evidence

AimTo analyze the rating of muscle discomfort and its correlation with risk factors among Malaysian traffic police riders using high-powered motorcycles.
MethodCross-sectional study
Procedure137 male traffic police riders (aged 20-39) completed a 100-mm visual analogue scale questionnaire rating perceived discomfort in 20 specific body regions. Data on riding duration and experience were also collected.
Sample137 participants
ContextOccupational use of high-powered police motorcycles

Variables

IV["Cumulative riding hours","Years of riding experience"]
DV["Rating of perceived muscle discomfort (e.g., lower back, hands)"]
CV["Age range of riders","Gender (male)","Type of motorcycle (high-powered)"]
04

Strengths & Limitations

Strengths

  • +Identifies specific body regions with high discomfort.
  • +Quantifies the correlation between riding duration/experience and discomfort.
  • +Focuses on an occupational group with specific usage patterns.

Limitations

Your own study might be limited by a small sample size, specific user group, or limited range of product variations tested.

Reliability & validity

The use of a standardized VAS questionnaire enhances reliability. However, the cross-sectional nature limits causal inference, and self-reported data may introduce bias, affecting validity.

Think critically

How might individual differences in rider posture, body mass, and pre-existing musculoskeletal conditions influence the reported discomfort levels, and how could a design accommodate such variability?

05

Design Principles

"Design for sustained comfort and reduced physical strain in occupational contexts."

This research directly addresses the physical toll on users in specific occupational contexts, highlighting the need for ergonomic considerations in vehicle design. Understanding these factors is crucial for designing safer and more comfortable equipment that supports user well-being and performance.

06

What This Means for Your Design

Riding a motorcycle for a long time, especially for work, really hurts your back and hands. The more you ride, the worse it gets.

How to use in your project

  • 1.Use this study to justify the need for ergonomic improvements in your design proposal, especially if it involves seating or prolonged use.
  • 2.Cite the findings on back and hand discomfort to support your user research and design decisions.

Paragraph starter

Research indicates that prolonged occupational use of high-powered motorcycles leads to significant musculoskeletal discomfort, particularly in the lower back and hands, with cumulative riding hours being a primary contributing factor (Nur Athirah et al., 2020). This highlights the critical need for ergonomic design considerations in such vehicles to mitigate long-term health issues and improve user performance.
