Henneman Size Principle
Recruit motor units
The Henneman size principle explains how motor units are recruited to control muscle movement. It states that motor units are recruited in a specific order, from low to high threshold, to conserve energy. Understanding this principle can help individuals optimize their workout routines to improve muscle strength and hypertrophy.
- Motor units are recruited in a specific order to conserve energy
- The recruitment of motor units is dependent on the intensity of the movement
- The Henneman size principle applies to all types of muscle movement, including voluntary and involuntary movements
- Understand the Henneman size principleLearn about the Henneman size principle and how it applies to muscle movement. Understand the concept of motor units and how they are recruited to control muscle movement.Pro tipFocus on understanding the underlying physiology of muscle movementWarningIgnoring the Henneman size principle can lead to ineffective workout routines
- Apply the Henneman size principle to workout routinesUse the Henneman size principle to optimize workout routines. Focus on recruiting motor units in the correct order to improve muscle strength and hypertrophy.Pro tipStart with low-intensity movements and progress to higher-intensity movementsWarningOverdoing it can lead to injury or burnout
- Monitor progress and adjust workout routinesMonitor progress and adjust workout routines as needed. Use the Henneman size principle to adjust the intensity and volume of workouts to continue making progress.Pro tipKeep a workout journal to track progressWarningPlateaus can occur if workout routines are not adjusted
An individual applies the Henneman size principle to their workout routine by starting with low-intensity movements and progressing to higher-intensity movements. They monitor their progress and adjust their workout routine as needed.
An individual ignores the Henneman size principle and starts with high-intensity movements. They do not monitor their progress and do not adjust their workout routine.
The Henneman size principle was first proposed by Elwood Henneman in the 1950s. Since then, it has been widely accepted and applied in the fields of muscle physiology and neuroscience.
