Short answer

Design roles and tasks that inherently involve moderate to high levels of physical activity can contribute to improved health outcomes for individuals, particularly older adults.

Field: Human Factors
Source: Journal of Physical Activity and Health (2023)
Method: Longitudinal observational study
Sample: 11 participants
Evidence: Strong effect

Engaging in high-volume physical activity, such as professional golf caddying, over a 24-week period can lead to significant improvements in balance, strength, body composition, and blood lipid profiles for middle-aged and older male adults. This human factors research insight is drawn from a 2023 study published in Journal of Physical Activity and Health. Using Longitudinal observational study with 11 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design roles and tasks that inherently involve moderate to high levels of physical activity can contribute to improved health outcomes for individuals, particularly older adults.

Sustained Physical Activity in Caddying Enhances Musculoskeletal Health and Body Composition in Older Adults

Journal of Physical Activity and Health · 2023

Key Findings

01Significant improvements in static and dynamic balance.
02Increased lower back strength and muscle quality.
03Positive changes in body composition (reduced body mass, fat mass, BMI).
04Improvements in blood lipid profiles (reduced total and LDL cholesterol).
05Increased light, moderate, and vigorous physical activity, with decreased sedentary time.

Application

Design takeaway

Design roles and tasks that inherently involve moderate to high levels of physical activity can contribute to improved health outcomes for individuals, particularly older adults.

How to apply

When designing for roles that require physical exertion, consider the potential for positive health impacts and ensure the design supports safe and effective movement patterns.

Project actions

01Consider how the physical demands of a product or system can be designed to encourage beneficial user activity.
02Investigate the physiological and psychological impacts of sustained physical engagement within a specific context.

Method & Evidence

AimTo investigate the effects of 24 weeks of professional golf caddying on the physical health markers of middle-older aged males.

MethodLongitudinal observational study

ProcedureEleven experienced male golf caddies underwent assessments for body composition, heart rate, blood pressure, blood lipids, and performance tests (balance, strength, fitness) at the beginning and end of a 24-week caddying season. Physical activity levels were also monitored.

Sample11 participants

ContextOccupational health and physical activity in sports support roles

Variables

IV24 weeks of high-volume physical activity (golf caddying)

DVBody composition, heart rate, blood pressure, blood lipids, static balance, dynamic balance, strength, submaximal fitness, physical activity levels, sedentary time

CVAge (middle-older aged males), experience level (full-time experienced caddies), duration of study (24 weeks)

Strengths & Limitations

Strengths

+Longitudinal study design allows for observation of changes over time.
+Inclusion of multiple health markers provides a comprehensive view of physical health.

Limitations

The findings are specific to male caddies and may not apply to other demographics or physically demanding jobs. The study did not measure potential negative impacts or injuries.

Reliability & validity

The study's reliability could be enhanced by a larger sample size and a control group. Validity is supported by the use of established health and performance measures.

Think critically

While caddying showed health benefits, it did not improve cardiorespiratory fitness. What does this suggest about the type of physical activity that is most beneficial, and how can design optimize for broader health improvements?

Design Principles

"Integrate sustained, functional physical activity into occupational design to promote long-term health and well-being."

This research highlights how occupation-based physical demands can positively impact the health of older adults. Designers and ergonomists can leverage this understanding to create work environments or design products that encourage sustained physical activity, potentially mitigating age-related health declines.

What This Means for Your Design

Working as a golf caddy for a long time made older men healthier by improving their balance, strength, body fat, and cholesterol, and they moved around more.

How to use in your project

1.Use this research to justify the inclusion of physical activity elements in a design, particularly if targeting older demographics or seeking to improve user health.
2.Reference findings on balance, strength, and body composition when discussing the user benefits of a physically engaging design.

Paragraph starter

Research indicates that sustained occupational physical activity, such as that undertaken by golf caddies, can lead to significant improvements in musculoskeletal health, balance, and body composition in middle-aged and older adults. This suggests that designing products or systems that encourage regular, functional movement can yield substantial health benefits, a critical consideration for user-centred design.
