Episode notes
Calf Complex Is More Than A Postural Muscle
- The calf complex (medial/lateral gastrocnemius + soleus) mainly produces plantarflexion moments and transmits huge forces through the Achilles tendon.
- These muscles are not just postural; they have complex internal architecture and specialized timing for gait and high-load tasks.
Soleus Versus Gastrocnemius Roles
- Soleus comprises ~70% of calf bulk and is ~80% type I, making it fatigue resistant and early-acting in stance to dissipate load.
- Gastrocnemius has a 50/50 fiber split and contributes more to forceful push-off later in stance.
Train Calves For Strength, Not Just Endurance
- Don't treat calves only as endurance muscles; include strength and peak-force work in rehab and training.
- Use heavy isometrics and slow resistance to raise the force ceiling, not just endurance heel-raise sets.
