Calf raise exercises for venous return
Czerniak explains that standing still for hours causes passive hyperemia (blood pooling) in the lower limbs, which is an occupational hazard for surgeons and anyone who stands without movement. The simple act of rising on the toes dynamically empties the deep veins. He insists this is the foundation for both prevention and management of existing varicose veins, because even if inflammation is already present, reducing stasis lowers further damage.
The contraction of the gastrocnemius and soleus muscles compresses the deep veins of the leg, forcing blood toward the heart and overcoming gravity. This reduces venous pressure and stasis, preventing the inflammatory distension that leads to varicose hernias. Czerniak refers to the calf muscles as ‘the muscle heart’ due to this central role in venous return.
