Understanding Muscle Fatigue and Injury Risk in Physically Demanding Jobs

In 2016 Seo, J., et al, looked at the impact of physically fatiguing work and the relationship to injury risk. Highlighting when the worker has fatigued, therefore reducing physical capacity, when exerting for to the physical capacity, musculoskeletal injury risk is high.

Fatigue isn’t just about feeling tired, it’s a physiological process that can significantly impact workplace safety and performance. The figure illustrates how repeated force exertions gradually reduce physical capacity, leading to fatigue failure and increased injury risk.

Key factors influencing this process include:
- Physical capacity and conditioning
- Health status and recovery behaviors
- Mental health and neurological patterns
- Previous injuries and job competency

Why does this matter?
In high-demand roles, understanding these dynamics helps organizations design better prevention strategies—reducing injuries, improving productivity, and supporting worker well-being.

How does your organization manage fatigue risk? Do you use proactive screening or recovery programs?

🤕 How to do a simplified Identification of Your Personal musculoskeletal MSK Injury Risk in 2 simple self tests

Simplified version based on my workplace MSK screening framework.

On a scale of 1–5, rate your:

1. Assess Your Movement Quality
Try these three movements:
• Bodyweight Squat
• Overhead Reach
• Single-Leg Balance (10 seconds each side)
👉 Ask yourself:
• Is the movement smooth and controlled?
• Do you feel any pain, restriction, or instability?
• Can you complete each movement without compensation (e.g., leaning, wobbling, or holding breath)?
Poor movement quality = increased MSK injury risk.

On a scale of 1–5, rate your:
3. Rate Your Readiness
• Mobility – Can you move freely without restriction?
• Strength – Can you control your body under load or during tasks?
• Recovery – Do you bounce back quickly after physical effort?

👉 Ask yourself:
• Do I feel physically prepared for the demands of my day?
• Am I noticing recurring soreness or fatigue?
• Would I benefit from targeted exercises or support?
Scores of 3 or below in any area = time to act.

Our full system:
We have developed a system to make a high value injury risk screening to the workplace through out online software.
1. The worker to answer a series of questions and identify any increased injury risks (see pic for sample report).
2. High or medium risk results yo complete a practioner assessment and early intervention program. Which will include a structured and guided program with an allied health profession (physio or Exercise Physiologist).

The benefit is, 1. only the workers at risk recieve the targeted intervention, meaning better ROI for the business and lower cost. 2. We are using evidence based systems to identify and prevent costly and harmful msk injuries.

🤯 “How to lift Manual handling training doesn’t work.”
It’s a common claim—but is it the full story?

In this blog we discuss why movement still matters and how outdated training models have led to confusion, poor outcomes, and no change in injury outcomes. Drawing from sport, rehab, and performance science, we show how movement quality, strength, and stability are still foundational to injury prevention.

Article explores:
• Why traditional lift training failed
• What the evidence *actually* supports
• How to evolve training from compliance to capability
• Why movement coaching, screening, and task-specific strategies are essential

If you're serious about reducing MSK injuries and building a culture of care—not just ticking boxe, have a read of the full article below:

Almost all workplace musculoskeletal injuries are preventable. Why has the data never changed?

Every year, to many workers suffer musculoskeletal injuries—from sprains and strains to chronic back pain. These injuries account for over 30% of all workplace compensation claims and cost businesses billions in lost productivity, treatment, and insurance premiums.

Yet, research shows that up to 80% of these injuries are preventable through proactive screening, task design, and education.

The problem:
• Most companies rely on outdated manual handling training.
• Few have systems to identify high-risk tasks or prevention initiative focused on injury prevention of the individual risk factors.
• Many interventions are reactive—only kicking in after someone gets hurt.

The solution = prevention:
• Evidence-based MSK injury risk screening tools
• Task-specific risk assessments and controls
• Personalised exercise programming
• Evidence based education/awareness provided in easy to consume formate
• Data-driven injury prevention strategies

We are aiming to shift from compliance to care for injury prevention, as it is the overall best approach for the employee and business. Compliance is important l, but a strategy to address the risks from an organisation, task and employee is key to reducing the impact of injuries on people and business.
