Acute Effects of Soleus Stretching on Ankle Flexibility, Dynamic Balance, and Speed Performance(prevent injuries)

A 2022 study published in the International Journal of Environmental Research and Public Health investigated how calf and soleus stretching affects lower-limb function and performance in soccer players.

The researchers examined the acute effects of soleus stretching combined with general calf stretching on ankle dorsiflexion range of motion (ROM), dynamic balance, and speed performance. Participants who performed the stretching protocol demonstrated significant improvements in ankle flexibility, plantar flexor strength, and movement speed compared to the control group (p < 0.05).

These findings indicate that stretching the soleus muscle—a deep calf muscle that supports ankle stability—can enhance both joint mobility and performance efficiency, which are key components of running mechanics. Improved dorsiflexion helps absorb impact and optimize push-off during running, potentially lowering the risk of calf strains, Achilles overuse injuries, and knee stress.

While the study involved soccer players rather than distance runners, the physiological benefits apply across sports requiring repetitive running movements. Thus, incorporating soleus and gastrocnemius stretching after training may contribute to injury prevention and better propulsion in runners.
