Introdução: As condições músculo-esqueléticas crónicas e persistentes, têm um enorme impacto
global e no indivíduo, contribuindo de forma substancial para a incapacidade e morbilidade. Estas
têm um impacto persistente na aptidão física dos indivíduos. É de extrema importância, ter
instrumentos fiáveis para avaliar as várias componentes envolvidas na aptidão física destes
indivíduos de forma a orientar planos de treino e intervenção. A aptidão física é composta por
quatro componentes que podem ser avaliadas por testes de campo simples, capacidade
cardiorrespiratória: 6-Minute Walk Test; controlo neuromuscular: Aberrant Movement Pattern e
Prone Instability Test; força muscular: Trunk Flexor Test, Side Bridge, Biering Sörensen Test e 60s
Sit-to-Stand; e flexibilidade: Sit-and-Reach Test, Schober Test e Modified Thomas Test. Para a
correta interpretação destes instrumentos é necessário conhecer as suas propriedades
psicométricas tanto em populações clínicas, como na população saudável. No entanto, existe
carência de dados na literatura, acerca da fiabilidade destes testes em indivíduos saudáveis.
Estabelecer conclusões sobre a fiabilidade destes testes, ajudará a interpretação fiável na prática
em população clínicas. Objetivo: Avaliar a fiabilidade intra-avaliador de uma bateria de testes que
avalia as várias componentes da aptidão física na população portuguesa saudável. Metodologia:
21 participantes foram submetidos a dois momentos de avaliação separados por 4.45 ± 1.70 dias,
onde foi aplicada a bateria de testes em estudo. Para aferir à cerca da fiabilidade dos testes, para
os com variável numérica foram calculados os CCI, e respetivos 95% IC, EPM e EPM%, assim
como intervalos de LDC, DMD e DMD%; para os testes com variável categórica, foram calculados
o coeficiente de k de Cohen, e % de concordância. Forma descritas frequências para todos os
testes. Resultados: Para os testes 6MWT, Trunk Flexor Test, Side Bridge, Biering Sörensen Test,
60s Sit to Stand, Sit-and-Reach Test, Schober Test e Schober Test para a extensão, foram obtidos
resultados de fiabilidade excelentes (CCI>0.94) e valores de EPM% baixos (EPM%<10.82%).
Enquanto, para os testes Aberrant Movement Pattern, Prone Instability Test e Modified Thomas
Test à esquerda fiabilidade moderada (k>0.61); e fiabilidade fraca (k=0.54) para o Modified
Thomas Test à direita. Foram obtidos valores de concordância altos para todos os testes de
variável categórica (%concordância>80.9%). Conclusões: Nos testes que se traduzem em
variável numérica, o SRT, SB, STE e STF apresentam fiabilidade excelente e baixo erro de
medição associado, enquanto os testes 6MWT, BST e 60STS, apesar de excelente fiabilidade,
apresentam algum erro de medição. O TFT é o teste que apresenta maior erro associado, ainda
que fiabilidade excelente. Nos testes que se traduzem em variáveis categóricas, o AMP, PIT e
MTT do lado esquerdo apresentam fiabilidade moderada, mas IC amplos e apresentam baixo erro
associado. Por fim o MTT do lado direito apresenta fiabilidade fraca e com IC amplo, ainda que o
erro relativamente baixo.
ntroduction: Chronic and persistent musculoskeletal conditions have a significant global impact, contributing substantially to disability and morbidity. These conditions have a persistent effect on the physical fitness of individuals. It is of utmost importance to have reliable instruments to assess various components involved in the physical fitness of these individuals to guide training and intervention plans. Physical fitness consists of four components that can be assessed by simple field tests: cardiorespiratory capacity (6-Minute Walk Test); neuromuscular control (Aberrant Movement Pattern and Prone Instability Test); muscular strength (Trunk Flexor Test, Side Bridge, Biering Sörensen Test, and 60s Sit-to-Stand); and flexibility (Sit-and-Reach Test, Schober Test, and Modified Thomas Test). For the correct interpretation of these instruments, knowledge of their psychometric properties is necessary in both clinical and healthy populations. However, there is a lack of data in literature regarding the reliability of these tests in healthy individuals. Establishing conclusions about the reliability of these tests will aid reliable interpretation in clinical populations. Purpose: To assess the intra-rater reliability of a battery of tests evaluating various components of physical fitness in the healthy Portuguese population. Methods: 21 participants underwent two separate assessment sessions spaced 4.45 ± 1.70 days apart, where the study test battery was applied. To assess the reliability of the tests with numerical variables, ICC, and their 95% CI, SEM, and SEM% were calculated, as well as LDC, MDD, and MDD%; for tests with categorical variables, Cohen's k coefficient and the percentage of agreement were calculated. Frequencies were described for all tests. Results: For the 6MWT, Trunk Flexor Test, Side Bridge, Biering Sörensen Test, 60s Sit to Stand, Sit-and-Reach Test, Schober Test, and Schober Test for extension, excellent reliability results (CCI>0.94) and low EPM% values (EPM%<10.82%) were obtained. Meanwhile, for the Aberrant Movement Pattern, Prone Instability Test, and Modified Thomas Test on the left, moderate reliability (k>0.61) was observed, and weak reliability (k=0.54) was observed for the Modified Thomas Test on the right. High agreement values were obtained for all categorical variable tests (%agreement>80.9%). Conclusions: In tests resulting in numerical variables, SRT, SB, STE, and STF exhibit excellent reliability and low associated measurement error, while the 6MWT, BST, and 60STS, despite excellent reliability, show some measurement error. The TFT is the test with the highest associated error, despite excellent reliability. In tests resulting in categorical variables, the AMP, PIT, and MTT on the left show moderate reliability, but with broad CI and low associated error. Finally, the MTT on the right shows weak reliability with a broad CI, although relatively low error.
