Several studies over the years have found that cross training is important for prevention of injury, as well as treatment of acute injuries. Cross training can be useful in the form of de-loaded activities such as cycling or pool running. Cycling is a fantastic means to improve your cardiovascular health, while giving the lower extremities a break from direct ground reaction forces. These ground reaction forces over time can cause tendinopathies, as well as in some cases, stress fractures. Allowing your body a chance to recover is so important for long term muscle health, and overall performance; however, many people have a hard time taking that “break” from running. This is why you’ll see many high performance runners are also avid cyclists: when you are feeling guilty for not running, you can mitigate that with a nice long bike ride. These rides can be useful to help clear swelling, or any unwanted byproducts, but they can also be used with heavier resistances and climbs to help build the quadriceps and hamstring muscle tone.
