Pretende-se perceber se existe uma relação entre o nível regular de actividade física praticado pelas pessoas idosas e a sua autonomia instrumental. Desenvolveu-se um estudo descritivo, correlacional e transversal, no ano 2010, com amostra intencional constituída por 100 indivíduos com idade igual ou superior a 60 anos, de ambos sexos. A colheita de dados foi efectuada em dois ginásios e dois centros de dia localizados na cidade de Lisboa, e foram utilizados como instrumentos a Escala de Actividades Instrumentais de Vida Diária de Lawton e Brody e o International Physical Activity Questionnaire. Obteve-se uma média de idades de 76 anos, sendo 78% dos inquiridos do sexo feminino. Inseriram-se 30% na categoria de actividade física “ligeira”, 45% na “moderada” e 25% na “vigorosa”. Relativamente à autonomia instrumental, a maioria era moderadamente dependente. Verificou-se que o grau de autonomia instrumental dos idosos aumenta com o incremento da actividade física praticada (ρS=0.815; p-value<0.001); Abstract: This work seeks to realize if there is a relationship between the level of regular physical activity practiced by elderly persons and its instrumental autonomy. A descriptive, related and transversal study was developed in the year 2010, with an intentional sample consisting of 100 individuals, aged 60 years or above, of both genders. The data collection was carried out in two gymnasiums and two day care centers located in the city of Lisbon, and were used the Lawton and Brody’s Instrumental Activities of Daily Living Scale and the International Physical Activity Questionnaire. A mean age of 76 years was obtained and 78% of the respondents were female. 30% were classified as having a "low" physical activity level, 45% as "moderate" and 25% as "high". Regarding instrumental autonomy, most were moderately dependent. It was verified that the degree of instrumental autonomy of the elderly increases with increased physical activity (ρS=0.815; p-value<0.001).

Lavandula spp. belong to the family Lamiatae and some species are often used in popular medicine and have been used for centuries in a large number of medical applications and in aromatherapy. Although similar ethnobotanical properties of Lavandula spp., its essential oils, general chemical composition and therapeutic applications differ from different species. Lavandula stoechas L. subsps. luisieri (Rozeira) Rozeira and L. viridis L’Hér are endemic to the Iberian Peninsula, widespread in the South of Portugal, namely in Southern Alentejo and Algarve. The aim of our study was evaluate the chemical composition and toxicological and pharmacological activities of leaves essential oils of spontaneous plants of L. stoechas L. subsps. luisieri (Alentejo) and L. viridis (Algarve). The essential oils of these wild plants, collected in spring, were obtained by hydrodistillation in a Clevenger-type apparatus and its chemical composition was evaluated by GC/FID. The acute toxicity of essential oils was evaluated "in vitro" using brine shrimp (LC50) and "in vivo" using Swiss mice (DL50). The analgesic and anti-inflammatory pharmacological properties of L. stoechas subsp. luisieri essential oil were evaluated in mouse or rats by the Amour-Smith and carrageen-induced paw edema tests, respectively. Results showed important differences in chemical composition of essential oils from two species analyzed either to diversity and proportion of its constituents. The essentials oils showed citotoxicity against Artemia salina and a DL50 higher than 2000 mg/kg for mice. The analgesic and anti-inflammatory activities of essential oils were exhibit for the doses of 100 and 200 mg/kg.
