"In any case, polyamory is about stable intimate, emotionally committed relationships rather than casual sex. Swinging is defined as recreational sexual activity, also called 'sport sex' where partner(s) or participant(s) agree to have casual sex with each other(s). There is usually no emotional involvement. Swingers generally practice recreational sex activities without the development of love, affection or personal intimacy. With polyamory, there is no such restriction, and the intent is to allow such emotional intimacy to exist, develop, and grow between the people involved."
