The Six-Minute Walk Test in Community-Dwelling Older Adult Women: The Influence of Physical Activity Levels and Age-Related Factors

Abstract

This study analysed cardiorespiratory variations during the 6MWT in older women according to their physical activity level and age-related variables such as pain, sarcopenia, frailty, and motivation to exercise. This study examined cardiorespiratory responses during the six-minute walk test (6MWT) in 163 older women with musculoskeletal pain, grouped by physical activity level. Heart rate, dyspnoea, and oxygen saturation were measured, along with pain, sarcopenia, frailty, and motivation to exercise. Results showed that lower physical activity was associated with higher heart rate, greater dyspnoea, and lower oxygen saturation. Sarcopenia, pain, and motivation also influenced these outcomes. These factors should be considered when interpreting 6MWT results and tailoring physical activity recommendations for healthy ageing.
