Avaliação dos grupos musculares adutores e abdutores do quadril por meio da dinamometria isocinética

Objective: To evaluate the activity of the adductor and abductor muscle groups of the hip in young adults by using an isokinetic dynamometer. Method: 20 male volunteers were selected, with ages varying between 21 and 30 years for evaluation on a Cybex 6000 isokinetic dynamometer, at angular speeds of 60°/s and 120°/s. Results: In relation to the dominance, it did not show any statistically significant differences at the two studied speeds. At these two speeds the maximum torque, the total work, and the average power presented statistically significant differences in all the comparisons. Comparing the muscle groups revealed statistically significant differences for the total work, with higher average values in the abductor muscle group studied at both speeds and the average power found higher mean values at 120°/s in the same muscle group. Conclusion: There was no statistically significant difference in relation to dominance. When comparing speeds, all variables showed a statistically significant difference in the prevalence of maximum torque and total work at 60°/s and average power at 120°/s. The statistical comparison between muscle groups showed significant differences for the total work at both speeds and the average power at a rate of 120°/s.Objective: To evaluate the activity of the adductor and abductor muscle groups of the hip in young adults by using an isokinetic dynamometer.

Concordância de diferentes critérios de sarcopenia em idosas comunitárias

The frequency and concordance between different sarcopenia criteria was assessed in community women of age. This is a cross-sectional study with 64 women of age, in which muscle mass was determined by bioelectrical impedance analysis (BIA) and skeletal muscle index calculation, muscle strength was determined with a handgrip strength dynamometer, functional capacity was determined with the tests Timed Up and Go (TUG) and Sit to Stand test (STS). This older population was classified in sarcopenic, pre-sarcopenic, moderate sarcopenic and severe sarcopenic by using different sarcopenia criteria. The data were analyzed with use of Chi-square test and Kappa statistics. The results obtained demonstrated that 37.5% of the women suffered of low muscle mass, 34.4% of muscle weakness, 3.1% of functional impairment to stand and walk and 25.9% to sit and raise from the chair. Considering only muscle mass, 37.5% of the sample was classified as sarcopenic (moderate or severe) and, considering the criteria of the European Working Groups on Sarcopenia in Older People, 15.6% obtained this classification when assessing functional capacity with TUG and 22.4% with STS. Concordance between sarcopenia definitions ranged from moderate to excellent (p<0.001). Among women with muscle mass integrity (n=40), 30% showed low handgrip strength, 2.5% showed impairment in TUG and 25.7% in STS. It was concluded that the women presented high frequency of sarcopenia, regardless of the criteria used. Moderate to excellent concordance was observed between the sarcopenia criteria investigated. Identification of older people with muscle mass integrity coexisting with muscle weakness and functional impairment reinforces the importance of the evaluation of the three parameters in the clinical scientific setting.Study performed in the Laboratory for Functional Human Performance at Universidade de Brasília – Brasília (DF), Brazil. 1Physical Therapist by Universidade de Brasília (UnB) – Brasília (DF), Brazil. 2Physical Therapy Committee of Universidade de Brasilia (UnB) – Brasília (DF), Brazil. 3Post-Graduate program in Gerontology of Universidade Católica de Brasília (UCB) – Brasília (DF), Brazil. 4Post-Graduate program in Rehabilitation Sciences of Universidade de Brasilia (UnB) – Brasília (DF), Brazil.
