Gerunds and infinitives can replace a noun in a sentence.
Gerund = the present participle (-ing) form of the verb, e.g., singing, dancing, running.
Infinitive = to + the base form of the verb, e.g., to sing, to dance, to run.
Whether you use a gerund or an infinitive depends on the main verb in the sentence.
I expect to have the results of the operation soon. (Infinitive)

Jumping off a cliff is dangerous, but a real thrill.
