Resumen
This work assessed the influence of treadmill gait training with neuromuscular electrical stimulation (NMES) on the metabolic and cardiorespiratory responses in quadriplegic subjects. The gait group (GG) (n = 11) performed 6 months of treadmill training with 30-50% body weight support and with the help of physiotherapists, twice a week, allotting 20 min for each session. The control group (CG) (n = 10), during the 6 months of training, did not perform any activity using NMES, performing instead conventional physiotherapy. Metabolic and cardiorespiratory responses (O-2 uptake [VO2], CO2 production [VCO2], pulmonary ventilation (V-E), heart rate [HR], and blood pressure [BP]) were measured on inclusion and after 6 months. For the GG, differences were found in all parameters after training (P < 0.05), except for HR and diastolic BP. During gait, VO2 (L/min) increased by 36%, VCO2 (L/min) increased by 42.97%, V-E (L/min) increased by 30.48%, and systolic BP (mm Hg) increased by 4.8%. For the CG, only VO2 and VCO2 (L/min) significantly increased at rest (30.82 and 16.39%, respectively) and during knee-extension exercise (26.29 and 17.37%, respectively). Treadmill gait with NMES was, therefore, more efficient toward increasing the aerobic capacity due to yielding higher metabolic and cardiovascular stresses. 30 1 56 63
