Muscle tears are a common soft tissue injury. They occur when muscle fibres are subjected to excessive force or stretched beyond their capacity, causing microscopic or macroscopic tears. This can happen when you pull a muscle too hard or use it too much, weakening the fibres. The severity of a muscle strain can vary from minor to major, with mild strains breaking tiny fibres and severe strains tearing through the muscle.

What You'll Learn
Muscle fibres can tear when they are stretched beyond their capacity
The micro tears hypothesis posits that during intense resistance training, muscle fibres experience tiny tears or damage, triggering the body to repair and rebuild these fibres, leading to muscle growth. However, there is no evidence to suggest mechanical tension causes micro tears.

Straining a muscle can cause the fibres to pull apart
Muscles are made up of thousands of small fibres woven together. When you strain a muscle, the strands of fibre are stretched beyond their limit and can tear apart. This can happen when you pull a muscle too hard or use it too much, which weakens the fibres. The tears can be microscopic or macroscopic.
A mild strain might only break tiny fibres within the fabric of the muscle, while a severe one can tear through it. Strains are painful, but most can heal with time and rest.
The micro-tears hypothesis posits that during intense resistance training, muscle fibres experience tiny tears or damage, triggering the body to repair and rebuild these fibres, leading to muscle growth. However, there is no evidence to suggest mechanical tension causes micro-tears.

Muscles are made up of thousands of small fibres woven together. When these fibres are subjected to excessive force or stretched beyond their capacity, they can tear. This can happen when you pull a muscle too hard or use it too much, which weakens the fibres.
Micro tears are tiny tears in the muscle fibres that can be caused by intense resistance training. The micro tears hypothesis suggests that during this type of training, muscle fibres experience tiny tears or damage, triggering the body to repair and rebuild these fibres, leading to muscle growth. However, there is no evidence to suggest mechanical tension causes micro tears.
Muscle strains can be minor or major. A mild strain might only break tiny fibres within the fabric of the muscle, while a severe one can tear through it. Strains are painful, but most can heal with time and rest.
