Third, base on the sex differential, the club members motive on participating in the leisure movement among five constructions, “the needs in health”, “the needs in social”, and “the needs in perceptual” have significant differences, and the female has higher score than male members; base on the age, “the needs in mental condition”, “the needs in health” are significant in the five constructions. For “the needs in mental condition”, the age over 51 gets higher score than the ages between 41 to 50, For “the needs in health”, the age between 21 to 30 gets higher score than the age over 51.
