Efeitos do treinamento aeróbio sobre a capacidade muscular e funcional em pacientes com diabetes mellitus tipo 2
Introduction: Diabetes Mellitus leads to reduced aerobic capacity as well as the reduction of respiratory muscle strength. Objective: To evaluate the impact of aerobic training (AT) on respiratory muscle strength (RMS) measured by maximal inspiratory (MIP) and expiratory (MEP) pressures, thoracic expansibility (TEx),  submaximal functional capacity (SFC) by 6-min walk test (6MWT) and muscular endurance (ME) of the lower limbs and flexibility in subjects with type 2 diabetes mellitus (T2DM). Materials and Methods: Prospective trial, non-randomized with 27 subjects with T2DM, which were allocated into AT group (G1) and control group (G2). Evaluations were performed before and after the RMS, TEx, 6MWT, lower limb ME and flexibility interventions. The AT lasted 8 weeks, three times a week, 60 minutes each. The prescription of AT was performed at 60-70% of maximum heart rate monitored by analog Borg scale. Results: The study shows that occurred an increase in the RMS (49% of the MIP and MEP), 6MWT, ME and flexibility in the G1 group. Conclusion: The TA was effective in improving respiratory muscle strength and functional capacity in patients with T2DM.
