Early Calf Rehab with Isometrics, Cross Training and Stairs

The strength profile from testing guides the plan: train the weakest quality, and if all are low, start with maximal strength. Early on, the runner should spend more time off their feet, since the soleus works during standing. Theraband isometrics and isotonics are useful only in the first days. Training around the injury helps. Seated work reduces gastrocnemius load, and foot position shifts emphasis, with toes turned in biasing the lateral calf and toes out the medial calf, based on work by Nunes. Training the uninjured leg maintains strength and gives a cross-education effect of up to 8 to 10%. The bike places the least load on the calf, with the cross trainer as a next step. Isometrics should be heavy: under a bar, in a Smith machine, under a heavy desk at home or on a leg press. The speaker uses 10 reps of 5-second holds, once or twice daily. Once a 30-degree single leg hold is possible, stair climbing begins: 10 flights with the heel kept high, up at around 90 beats per minute and slowly down.
