Equivalência transcultural de três escalas utilizadas para estimar a aptidão cardiorrespiratória: estudo em idosos

Abstract

O objetivo deste estudo foi realizar a equivalência transcultural de escalas empregadas para a avaliação do nível de atividade física e que são utilizadas como estimativas da aptidão cardiorrespiratória, para posterior utilização em indivíduos idosos. Três escalas foram determinadas após revisão sistemática: Veterans Physical Activity Questionnaire (VSAQ), Rating of Perceived Capacity (RPC) e Physical Activity Rating (PA-R). Para a análise da equivalência, utilizou-se o modelo proposto por Herdman et al. Como parte do processo, a confiabilidade teste-reteste foi avaliada em uma amostra composta por 12 idosos com idade de 74,5 ± 3,5 anos, pelo cálculo dos coeficientes de concordância de Lin (CCL) e de correlação intraclasse (CCI). Detectou-se uma boa reprodutibilidade das escalas com exceção do RPC. Apesar de a quantidade de indivíduos não permitir conclusões mais aprofundadas, os resultados podem indicar necessidade de mudanças na estrutura de algumas escalas originais. Por fim, acredita-se que os resultados obtidos no presente estudo sugerem a adequação das versões das escalas para a língua portuguesa, havendo, todavia, a necessidade de um estudo de validade de critério das escalas.

Transcultural adaptation of the filial responsibility interview schedule for Brazil*

“…Some studies emphasize the importance of this synthesis for a more appropriate version for the context of the study (Gjersing et al. 2010; Maranhão Neto et al. 2008; Yu et al.…”

“…2008). Similar to other studies of cultural adaptation (Maranhão Neto et al. 2008; Weissheimer 2007), an evaluation of the back‐translated version was conducted by another professional who was proficient in both languages and an expert in the area.…”

Determination of Best Criteria to Determine Final and Initial Speeds within Ramp Exercise Testing Protocols

“…Three nonexercise models were employed to estimate maximal cardiorespiratory capacity and therefore the final speed. The choice of VSAQ, RPC, and CRF to estimate the V O 2 max⁡ was due to the fact that these instruments have been frequently applied in previous studies and have been shown to have good potential to estimate the maximal cardiorespiratory capacity in different populations [23, 24]. Two relative intensities (% V O 2 max⁡ ) using different initial treadmill speeds were tested.…”

“…A large sample ( N = 799) of men and women aged 19 to 79 years was tested. The estimated V O 2 max⁡ was compared to directly measured data, and the questionnaire was cross-validated with another population, which is uncommon in studies assessing such instruments [23, 24]. …”

Assessment of Cardiorespiratory Fitness without Exercise in Elderly Men with Chronic Cardiovascular and Metabolic Diseases

“…The subjects were asked to choose one of five activity categories that best described their usual pattern of daily physical activities. Self-rated fitness was evaluated by means of the Rating of Perceived Capacity scale (RPC), a 1-20-scale previously adapted and translated to the Brazilian Portuguese language [12], in which the subject chooses the most strenuous activity that can be sustained for at least 30 min [13]. The RPC score is expressed in METs and the listed activities include walking, jogging, running, and cycling at different paces.…”
