Cenforce Soft, which contains sildenafil citrate, is primarily used to treat erectile dysfunction by enhancing blood flow to the penis. Its impact on exercise capacity, however, is not its primary function, but sildenafil has been studied for its potential effects on physical performance.

Some research suggests that Cenforce Soft may improve exercise capacity by enhancing blood flow, oxygen delivery, and reducing pulmonary pressure, especially in individuals with conditions like pulmonary hypertension. However, in healthy individuals without such conditions, the effect may be minimal. It's important to note that using Cenforce Soft or any medication off-label should only be done under the guidance of a healthcare provider, as potential side effects and risks exist.
