    BACKGROUND: Because the incremental shuttle walk test (ISWT) requires agility in its performance, we hypothesized that the test may be associated with balance and risk of falls in the elderly. Objective: To evaluate and compare the association between the performance on the ISWT, the timed up and go (TUG) and the occurrence of falls in the elderly. METHOD: Thirty-three elderly individuals (68±7 years) performed the TUG and the ISWT. Balance was assessed using the Berg Scale (BBS). Participants who fell at least twice in the last 12 months were placed in the falls group (FG) and all other participants comprised the control group (CG). RESULTS: There were seventeen elderly women in the FG and 16 in the CG. Participants from the FG had a significant worse performance (p<0.05) on the TUG (8.01±0.22 vs. 6.22±0.21 s), BBS (51±3 vs. 55±1 points) and ISWT [313±79 (92±15%pred.) vs. 395±75 m (113±19%pred.)] than participants from the CG. The ISWT significantly correlated with the TUG (r=-0.75, p<0.001), BBS (r=0.50, p=0.002) and number of falls (r=0.36, p=0.031). After logistic regression, the TUG was determinant (p=0.03) and the ISWT showed a tendency to determine the occurrence of falls (p=0.05). CONCLUSION: The ISWT was a valid measure to assess the risk of falls and balance and therefore, may be useful for the simultaneous assessment of cardiorespiratory fitness and balance in older women.

    Avaliação da capacidade de exercício de pacientes com escoliose idiopática do adolescente pelo incremental shuttle walk test
    (Universidade Federal de São Paulo (UNIFESP), 2013-02-27) Sperandio, Evandro Fornias [UNIFESP]; Dourado, Victor Zuniga [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Although the exercise limitation of patients with adolescent idiopathic scoliosis (AIS) has been described in cardiopulmonary exercise testing, there is scarce information about the todal distance traveled and physiological responses related to the incremental shuttle-walk test (ISWT) in these patients. Objective: To evaluate the total distance traveled (ISWD) and physiological responses to the ISWT in patients with AIS and in healthy adolescents. We also evaluated the respiratory muscle strength and pulmonary function of the participants. Methods: Twenty-nine adolescents with EIA (Cobb angle = 40 ± 13o) and 20 healthy adolescents aged between 10 and 18 years performed two ISWT. During the second test, oxygen uptake (VO2), CO2 production (VCO2), ventilation (VE) and heart rate (HR) were monitored using a telemetric gas analyzer. The submaximal relationshps ΔVO2/Δwalking velocity, ΔHR/ΔVO2, ΔVE/ΔVCO2, and linearized Δtidal volume (VT)/ΔVE (ΔVT/ΔlnVE) were evaluated by linear regressions, representing respectively aerobic, cardiovascular and respiratory eficiencies, and breathing pattern. Maximal inspiratory (MIP) and expiratory (MEP) pressures, forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and FEV1/FVC were also evaluated. Results: Patients with AIS showed ISWD (498 ± 144 m), peak VO2 [median (interquartile range), 25 (21-27) mL/min/kg] and VE (43 ± 16 L / min) significantly reduced at the end of the ISWT compared to control participants [respectively 604 ± 85 m, 28 (24-33) ml/min/kg and 52 ± 14L/min). Patients with AIS showed significantly worse respiratory pattern during ISWT (ΔVT/ΔlnVE: 0.32 ± 12 vs. 0.45 ± 16). In patients, peak VO2 correlated significantly with ISWD (r = 0.80), FVC (r = 0.78), FEV1 (r = 0.73) and ΔVT/ΔlnVE (r = 0.58). The MIP, MEP, FVC and FEV1 were also significantly lower in patients [(respectively, 54 ± 19 vs. 78 ± 25 cmH2O, 50 (37-62) vs. 80 (60-85) cmH2O; 2.77 (2.48 to 3.17) vs. 3.33 (3.16 to 3.81) L and 2.51 ± 0.68 vs. 2.94 ± 0.66 L)]. Conclusion: Patients with AIS showed a significant reduction of functional exercise capacity associated with reduced pulmonary function. The ISWT was able to quantify this impairment. There was no influence of severity of scoliosis on functional exercise limitation. Our results suggest that walking-based aerobic exercises should be encouraged in patients with AIS.

    Equações de referência para o teste de caminhada de seis minutos em indivíduos saudáveis
    (Sociedade Brasileira de Cardiologia - SBC, 2011-06-01) Dourado, Victor Zuniga [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    The six-minute walk test (6MWT) has been broadly used in clinical settings. Several reference equations for prediction of the total distance walked during the test (6MWD) are available in literature. The present review aimed to critically discuss studies, published in Portuguese and English (LILACS, SCIELO, MEDLINE, PUBMED), which evaluated normal values and created reference equations for predicting 6MWD in healthy subjects, comparing them with the results that were recently obtained in Brazilian individuals. Age, sex, weight, height and body mass index were the main demographic and anthropometric features more often correlated with 6MWD. The equations derived from these characteristics were able to explain between 25 and 66% of the total variability in the 6MWD. Unfortunately, the foreign equations were not applicable to the Brazilian population. Even when the 6MWT was performed following strict standardization, the difference in 6MWT performance between foreign and Brazilian individuals remains, indicating the necessity of providing specific reference equations for each population and/or ethnic group. Accordingly, these equations developed in Brazil are probably the most appropriate for interpreting 6MWT performance in Brazilian patients with chronic diseases affecting the exercise capacity. Future studies are necessary with larger sample sizes (e.g. multicentric ones) and randomized design for the reference values of the 6MWD to be considered reliable.
