Calf strains commonly occur due to tightness in the calf musculature, which may be precipitated by hip and ankle inflexibility. During walking or running gait the hip and ankle require a certain amount of flexibility for a proper stride. If the hips and/or ankles are tight due to too much sitting, repetitive athletic endeavors, or wearing high heels, the calf will be forced to work harder during gait. As calf muscles become tighter, they become shorter and subject to increased tension. Any muscle under these conditions may develop strains, micro tearing, and subsequent scar tissue, which further shortens and weakens the muscle. This cycle repeats itself until other tissues become involved, such as the Achilles tendon.  Deep tissue release, mobilization of the ankle & foot, and foam rolling is an excellent formula for resolving this condition.
