Why People Keep Getting Injured: Understanding Load and Capacity

One of the most common conversations I have with patients is about why injuries keep coming back.

Often, people assume the problem is weakness, poor technique, or simply bad luck. In reality, repeated injuries are usually linked to something much simpler: a mismatch between the load placed on the body and the capacity of the tissues to handle it.

The Mountain Analogy

One way I often explain this concept is by comparing training to climbing a mountain.

When climbers attempt a large mountain, they don’t simply head straight to the summit. Instead, they climb up, descend slightly, and allow their bodies time to adjust to the altitude before climbing higher again.

This gradual process allows the body to adapt safely to increasing stress.

Training and rehabilitation should work in much the same way.

As we increase the load placed on muscles, tendons, and joints, the body responds by becoming stronger and more resilient. However, this adaptation takes time.

What Often Goes Wrong

Many injuries occur when people attempt to “sprint to the summit.”

For example, this might look like:

• Suddenly increasing running mileage

• Returning to high-intensity gym training too quickly

• Skiing for long days without adequate preparation

• Jumping straight back into sport after a period of inactivity

When the increase in load is too large or too sudden, the body does not have sufficient time to adapt. This is when tissues can become overloaded, leading to pain or injury.

Building Capacity

In rehabilitation and performance training, the goal is not simply to remove pain or avoid movement. Instead, the focus is on gradually building the body’s capacity to tolerate load.

This involves progressively increasing stress through structured training so that muscles, tendons, and joints can adapt safely over time.

Elite athletes are not injury-resistant because they are lucky. They are injury-resistant because their training is carefully structured to build load tolerance progressively.

The Takeaway

Injury prevention is not about avoiding stress on the body.

It is about introducing stress gradually enough for the body to adapt.

In other words, successful training and rehabilitation should resemble climbing a mountain -gradual, structured progress rather than a rushed attempt to reach the summit.
