Reprodutibilidade do teste de 1-RM em indivíduos com doença arterial obstrutiva periférica / Reproducibility of the 1-RM test in individuals with peripheral obstructive arterial disease
A força máxima aumentou significantemente da primeira para a segunda sessão de teste nos dois membros (4,1 ± 14,3 por cento na perna com menor ITB e 5,9 ± 13,1 por cento na perna com maior ITB). A análise dos limites de concordância revelou que, nos dois membros, as maiores diferenças médias e os maiores limites de concordância foram observados quando comparadas as sessões 1 e 2.
CONCLUSÃO:
A medida acurada da força máxima usando o teste de 1-RM, no exercício extensão de joelhos, em indivíduos com DAOP e sintomas de claudicação intermitente, é obtida quando duas sessões de testes de 1-RM são realizadas.
INTRODUCTION:
Patients with peripheral obstructive arterial disease (PAD) present muscle atrophy and reduced strength in the legs which have been associated with impairment in physical function. Consequently, the assessment of leg strength can be useful for identifying muscle weakness and analyzing the efficacy of intervention programs for patients with PAD.
OBJECTIVE:
To assess the reliability of the 1-RM test in patients with PAD.
Methods:
The sample was composed of twenty-six patients with PAD and symptoms of mild intermittent claudication. Patients performed the 1-RM tests in the knee extension exercise in the leg with lower ankle brachial index (ABI) and in the leg with higher ABI. This protocol was repeated in four sessions to assess the reliability of the maximum strength measurements.
RESULTS:
Maximal strength increased significantly from session 1 to session 2 in both legs (4.1 ± 14.3 percent in the leg with lower ABI and 5.9 ± 13.1 percent in the leg with higher ABI). The analysis of agreement revealed that higher bias and higher limits of agreement were observed in both legs when sessions 1 and 2 were compared.
CONCLUSION:
Reliable assessment of strength using 1-RM test in knee extension exercise in patients with PAD and symptoms of intermittent claudication is obtained when 2 test sessions are performed.
