OBJECTIVES: To determine the power-duration relationship in upper limb exercises and to investigate the relationships between parameters derived from this function with physiological indicators of aerobic fitness. METHODS: Ten healthy men (26.2±2.3 years, 75.0±11.8 kg, 178.2±11.5 cm and 15.0±5.7% body fat) performed a ramped test on an arm cycle ergometer with increments of 20 W/min. Subsequently, five tests with constant load were performed until exhaustion, with 70, 80, 90, 95 and 100% difference between VT1 and VO2peak. The critical power (CP) was obtained by means of linearization of the power-duration function. RESULTS: The power-duration relationship was described using an adjusted function (r=0.98±0.02). The VO2 at CP (2.66±0.62 l/min) was higher than VT1 (1.62±0.38 l/min) and VT2 (2.36±0.59 l/min), but lower than VO2peak (3.06±0.62 l/min). The CP workload (103.0±26 W) was significantly different from VT1 (69.5±21 W) and VO2peak workloads (151.0±26.3), but was no different of VT2 (103.5±30.8 W). The association between critical power and aerobic condition indexes were always significant when expressed as VO2 (0.73 to 0.78, p<0.05) and in W (0.83 to 0.91, p<0.05). Determination of CP in upper-limb dynamic exercises is simple and inexpensive, and can be used by physical therapists for prescribing and evaluating upper-limb training programs. CONCLUSIONS: The power-duration relationship in upper-limb exercises can be described by a hyperbolic function and it is associated with physiological indicators of aerobic fitness.

OBJECTIVES: To determine whether there is an association between the Q-angle (Q) and the distribution of plantar pressure in football players, and to compare the characteristics of these athletes with non-practitioners of this sport. METHODS: 121 male participants were selected: 50 football practitioners (FP) and 71 non-practitioners (NP). We concurrently evaluated the Q-angle and the plantar pressure through the software of postural assessment (SPA) and the F-Mat System, respectively. To verify the correlation between the Q-angle and peak pressure values in four segments of the foot (medial and lateral forefoot, medium-foot and hind-foot), the Pearson coefficient (r) for parametric analysis was used. The independent t-test was used to compare these variables between the groups. Data normality was verified by the skewness values, adopting a significance level of 5%. RESULTS: A negative and weak correlation was found (r=-0.32) between the Q-angle and the plantar pressure in the right medium-foot. The groups differed with regards to the right Q-angle (11.36o in FP versus 13.80o in NP) and the left Q-angle (11.03o in FP versus 13.96o in NP). Plantar pressure was also different between the groups, with FP showing higher mean values for the right side and for the left side of the forefoot (0.77 kg/cm2 in FP versus 0.63 kg/cm2 in NP, and 0.65 kg/cm2 in FP versus 0.54 kg/cm2 in NP, respectively). However, mean peak pressure values for the left medium-foot were higher among NP (0.37 kg/cm2 in FP versus 0.46 kg/cm2 in NP). CONCLUSIONS: There was no evidence of an association between the Q-angle and the distribution of plantar pressure in FP. The athletes showed reduced Q-angle values and higher mean peak pressure values for the right and left aspects of the forefoot, suggesting a varus malalignment and a supine distribution of plantar bases.

CONTEXTUALIZACAO: A faixa etaria que mais cresce no Brasil e no mundo e a de idosos com 80 anos e mais. Entre esses individuos, a prevalencia de incapacidades e morbidades e maior que em outros grupos. OBJETIVOS: Investigar a influencia de fatores socioeconomicos, demograficos, biologicos e de saude, nutricionais, de relacoes sociais, alem da autoavaliacao da saude sobre a capacidade funcional de idosos longevos (80 anos e mais). METODOS: Trata-se de um estudo transversal, de base populacional, em que os dados foram obtidos por meio de questionarios e medidas antropometricas. A capacidade funcional foi avaliada utilizando-se o modelo desenvolvido por Andreotti e Okuma (1999). Foram realizadas analises univariada e multivariada. RESULTADOS: Os fatores independentes associados a pior capacidade funcional foram: ter 85 anos e mais (OR=2,91), ser do genero feminino (OR=6,09), fazer uso continuo de cinco ou mais medicamentos (OR=2,67), nao visitar parentes e/ou amigos pelo menos uma vez por semana (OR=11,91) e considerar a propria saude pior que a de seus pares (OR=4,40). CONCLUSOES: Os resultados sugerem que a capacidade funcional esta associada a uma complexa rede de fatores multidimensionais, sendo importante o desenvolvimento de acoes relacionadas aqueles fatores que sao passiveis de intervencao, visando propiciar melhores condicoes de saude e qualidade de vida a esses individuos.

OBJECTIVES: To evaluate the health-related quality of life (HRQOL) of elderly people with total hip arthroplasty (THA) and to investigate the relationships and influences of the sociodemographic, clinical and functional variables of these subjects. METHODS: The HRQOL was evaluated by means of the Brazilian versions of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), a general instrument, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a specific instrument. Eighty-eight elderly people of both genders with primary unilateral THA were recruited. The data were subjected to descriptive analysss, univariate analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) to investigate the influences of the variables studied in the dimensions of the SF-36 and WOMAC; and the Mann-Whitney and Kruskal-Wallis tests to compare instrument scores between the variables. RESULTS: There was a predominance of women in the study sample, and their mean age was 68.8 (± 7.4) years. Hip function, as assessed by the Harris Hip Score, had a significant influence on HRQOL from the perspective of both the general and the specific instruments. The use of accessories for locomotion, hip functions and satisfaction with the surgery were the main variables that demonstrated significant differences in the dimensions of the SF-36 and the WOMAC. CONCLUSIONS: Investments in functional and rehabilitation programs aimed towards the peculiarities of elderly people with THA can benefit this population.

CONTEXTUALIZACAO: O envelhecimento compromete a habilidade do sistema nervoso central (SNC) de realizar a manutencao do equilibrio corporal bem como diminui a capacidade das reacoes adaptativas. Para prevenir as quedas, e necessario aprimorar as condicoes de recepcao de informacoes sensoriais. OBJETIVOS: Comparar o impacto de um programa estruturado de exercicios de resistencia muscular dos membros inferiores dentro e fora d'agua no equilibrio estatico e dinâmico em idosos. METODOS: Trata-se de um estudo clinico, prospectivo, aleatorio, em que as variaveis utilizadas foram avaliadas antes e apos o programa de treinamento. Foram avaliados 36 idosos por meio de quatro testes: Escala de Equilibrio de Berg, Dynamic Gait Index, velocidade da marcha, Marcha Tandem. Posteriormente, houve a alocacao dos voluntarios em tres grupos: grupo de exercicio na piscina terapeutica, grupo de exercicio no solo e grupo controle. Os grupos de exercicios foram submetidos a um programa de resistencia muscular dos membros inferiores aplicado durante seis semanas, duas sessoes semanais com 40 minutos de duracao. Os voluntarios foram reavaliados apos seis semanas. Os dados foram analisados estatisticamente pelo teste ANOVA univariada para comparacao entre os tres grupos antes e apos a intervencao. RESULTADOS: O programa de resistencia muscular dos membros inferiores promoveu aumento significativo do equilibrio dos idosos (p<0,05) nos testes avaliados apos o programa de treinamento. CONCLUSAO: O programa de resistencia muscular proporcionou uma melhora significativa no equilibrio estatico e dinâmico de idosos comunitarios. Foi possivel inferir tambem que essa melhora ocorreu independentemente do meio em que o programa foi realizado, ou seja, se dentro ou fora d'agua.

OBJECTIVES: The aim of this study was to compare the performance of the sensory and motor systems and the contributions of possible differences to postural control. METHODS: Twenty older adults (68.9±3.7 years of age) and twenty young adults (21.9±2.1 years of age) underwent visual, somatosensory (tactile and kinesthetic sensitivity), motor tests (joint torque and muscle activation latency) and postural control assessments (upright semi-tandem posture). RESULTS: MANOVA and ANOVA indicated that older adults had a poorer performance in the sensory tests: visual acuity (p=0.001), visual contrast sensitivity (p=0.009), tactile sensitivity (p<0.001) and kinesthetic sensitivity of the knee (p<0.001) and ankle (<0.001); and in the motor tests: female (p=0.010) and male (p<0.001) knee flexion torque; female (p=0.002) and male (p<0.001) knee extension torque; female (p=0.029) and male (p=0.006) ankle dorsiflexion torque; female (p=0.004) and male (p=0.004) ankle plantar flexion torque; and muscle activation latency (p<0.001). The older adults also had greater body sway amplitude on the anterior-posterior direction (p=0.035). Multiple regression analysis revealed that perception of passive motion was the only variable that contributed to greater body sway on the anterior-posterior direction among older adults (R2=0.142; p<0.05). CONCLUSIONS: There are differences in sensory and motor performance between young adults and older adults, and attention should be directed toward the contribution of the proprioceptive system to postural control among older adults.

INTRODUCTION: There is a lack of data in the literature for determining the influences of the extensor portion of the gluteus maximus muscle on pelvic tilting and, thus, on lumbar stability. OBJECTIVES: To assess the influences of the extensor portion of the gluteus maximus muscle on pelvic tilt. METHODS: Ten healthy young subjects were recruited, with a body mass index (BMI) below 24.9 kg/m2 and leg length discrepancy below 1 cm. The BMI, pelvic perimeter and lower-limb lengths were assessed and, subsequently, the degrees of hemi-pelvic tilt and asymmetry between them were analyzed using lateral view photographs of the subjects in a standing position, using SAPO (Software for Postural Assessment). Next, fatigue was induced in the extensor portion of the gluteus maximus muscle on the dominant side, and after that the hemi-pelvic tilt and the asymmetry between the hemi-pelvises were reassessed. The Pearson r and Student t tests were conducted at the significance level of α=0.05. RESULTS: There were no significant correlations between the confounding variables and asymmetry of the hemi-pelvic angles. There were significant changes in the hemi-pelvic angle of the dominant side (t=3.760; p=0.004). CONCLUSIONS: Fatigue in the extensor portion of the gluteus maximus muscle can generate increases in the tilt angle of the ipsilateral pelvis.
