Normative Values and Reference Equations of a New Incremental Step Test for the Assessment of Exercise Capacity for Portuguese Adults

Overview

According to the official guidelines, a range of settings for cardiorespiratory rehabilitation, including the community- and home-based models, are considered to answer to the inadequate number of rehabilitation services, especially at hospitals, and, also, to respond to the patients' needs. For these settings outside the hospitals, new strategies for the assessment of exercise capacity and exercise training are essential. The modality of stepping can be a promising tool because it is inexpensive, portable, and reflects one of the main activities of daily living (stair climbing). The development of a new field test implies the establishment of normative values and reference equations generated from data of populations without disabilities to aim to characterize a defined population at a specific period of time, and evaluate and compare an individual's performance within a population.

The primary aim of this project is to establish normative values and reference equations generated from Portuguese adults without disabilities of a new step test for the assessment of exercise capacity. The investigators will perform a cross-sectional study in Portuguese adults (over 18 years) without disabilities. The study will be advertised at the university campus, surrounding areas, and interested participants can contact the research team for participation. The participants who agree will be seen by the principal investigator who will explain the nature of the study and assess eligibility for the study. The participants will sign informed consent. For each participant, the study will be performed in one day. The participants will perform the incremental step test twice (30 minutes apart). In addition, socio-demographic information (age and sex), anthropometric measures (weight, height, and body mass index), and clinical data (smoking status, comorbidities, and level of physical activity) will be collected.
