Introdução: Estima-se que 49% dos idosos de Portugal tenham 75 ou mais anos de idade.
Estes idosos são a classe mais sedentária e com maior declínio funcional e incapacidade. As
guidelines de Atividade Física (AF) recomendam que esta seja no mínimo de intensidade
moderada para que se obtenham benefícios em saúde. No entanto começa a ser sugerida a
associação da Atividade Física de Intensidade Ligeira (AFIL) com algumas variáveis em
saúde. Contudo, poucos estudos abordam a associação da AFIL com indicadores de saúde
nos idosos. Objetivo: Identificação dos níveis auto-reportados de AFIL e sua associação
com a dor, número de quedas e capacidade funcional. Metodologia: Realizou-se um estudo
analítico observacional transversal, com uma amostra constituída por 65 participantes entre
os 75 anos e os 96 anos de idade e uma média de idade de 79,48 ± 4,98. As variáveis em
estudo foram a AFIL, avaliada pelo Diário de AF, a dor e número de quedas, avaliadas no
questionário de caracterização da amostra e a capacidade funcional avaliada pelo “Short
Physical Perfomance Battery” (SPPB). Resultados: A média diária do tempo passado em
AFIL foi de 268±107,80 minutos. Existiu uma associação positiva estatisticamente
significativa (rs=0,45; p≤0,01) entre a AFIL e o SPPB. Não se obtiveram associações
estatisticamente significativas entre a AFIL e a dor ou o número de quedas. Conclusão: Os
resultados demonstram uma associação positiva significativa entre a AFIL e a capacidade
funcional. Sugere-se a realização de mais estudos da associação da AFIL com indicadores
relevantes para a população idosa, por esta poder ser uma alternativa viável e mais realista à
AF de intensidade moderada ou vigorosa nos idosos, essencialmente os inativos, pouco
ativos ou os com maior fragilidade, aparentando menos riscos de lesão e maior adesão à sua
execução e similarmente poder contribuir para a diminuição dos comportamentos
sedentários.
Background: It is estimated that 49% of the elderly in Portugal are 75 years old or older. These old adults are the most sedentary class of people and with more functional decline and incapacity. Current Physical Activity (PA) guidelines advise on PA of at least moderate intensity for health benefits. Accumulating evidence suggests that PA of light intensity might be beneficial in some health variables. However, studies explore the association of Lightintensity Physical Activity (LIPA) with health benefits in elderly. Aim: The purpose of this study is to identify the self-reported levels of LIPA of people aged 75 years and over and their association with pain, number of falls and physical performance. Methods: It’s a crosssectional observational study with a sample of 65 participants aged 75 to 96 with a mean age of 79,48 ± 4,98. The LIPA levels was assessed by a diary of PA. Pain and number of falls data were given by the sociodemographic and clinic survey. The Physical performance was assessed by the Short Physical Perfomance Battery (SPPB). Results: Participants accumulated 268 ±107,80 (mean ± SD) minutes of LIPA per day. A statistically significant positive correlation was found between LIPA and SPPB (rs=0,45; p=0,01). LIPA was not correlated significantly with pain or number of falls. Conclusion: In the present study, the LIPA was positively associated with physical performance. There should be more studies in the future about this intensity of PA, perhaps a feasible and more realistic alternative to the moderate-intensity PA or exercise on the elderly, especially the inactive, insufficiently active, or the frailty ones, presenting lower risk of injuries and better compliance and due the possible contribution to decrease the time spent on sedentary behaviours.
