This experimental study aimed to analyse the effects of an aerobic activity intervention delivered by specially trained instructors to a sample of Italian older people living in a residential care facility. We assessed intervention effects on general health perception, perception that one's health represents a limitation for moderate and heavy physical activity, and positive and negative self-perception. The 36-item Short Form Health Survey Questionnaire (SF-36) was administered at pre-test and post-test to a sample of 22 older people (ten in the control group and 12 in the intervention group) of both genders with an average age of 80.6 years. The findings showed that: (a) the perception that one's health can limit moderate and heavy physical activity decreased significantly in the older people belonging to the intervention group between pre- and post-test, while it increased in the control group; (b) positive self-perception was found to be stable in the intervention group, while it decreased in the control group; and (c) there was no interaction between group and time with respect to both general health perception and negative self-perception. The exercise programme seemed to have a particularly positive effect on older people's beliefs about their ability to master successfully the activities of daily living such as walking and moving objects.
