RESULTS: Although there are low scores present in the instrument, there have been noticed good results in physical capacities. Muscular strength seems to be an influencing variable on physical and social functioning and mental health (p<0.05). Motor coordination influence on Vitality (p <0.05) was also remarked. As to equilibrium, it presents a negative interaction (p <0.03) with social functioning.
