  "abstract": "Capturing functional exercise capacity is important in guiding treatment and assessing the efficacy of interventions for individuals with chronic respiratory conditions.1 Laboratory-based exercise testing, specifically cardiopulmonary exercise testing (CPET), is considered the gold standard.1 This test provides detailed physiological insights, but is time-consuming and requires specialised equipment, which limits its implementation in routine practice.2 Conversely, field tests like the 6-minute walk test (6MWT) or incremental shuttle walk test are simpler, better related to physical activity and have become standard practice for regular assessments.2 These tests provide more limited physiological information. Despite their simplicity, field walking tests still require substantial space and time, which may restrict their use in clinical and real-world settings.2 There has been growing interest in simpler tests suitable for routine screening and treatment follow-up to complement existing measurement tools. Among these, the sit-to-stand (STS) tests have emerged as promising.3 In this latest issue of Thorax, Farley and colleagues present a timely and comprehensive systematic review of the measurement properties of STS tests in community-dwelling individuals with chronic obstructive pulmonary disease (COPD).4 Notably, nearly half of the included studies were published within the last four years, underscoring an expansion of evidence since a review in 2017.3",
