Text: The training-induced changes were significantly greater in the SEMT group than in the control group for the following variables : expiratory muscle strength (from 86 + / - 4. 1 to 104 + / - 4. 9 cm H (2) O, p < 0. 005 ; mean difference from the control group, 24 % ; 95 % confidence interval, 18 to 32 %), expiratory muscle endurance (from 57 + / - 2. 9 % to 76 + / - 4. 0 %, p < 0. 001 ; mean difference from the control group, 29 % ; 95 % confidence interval, 21 to 39 %), and in the distance walked in 6 min (from 262 + / - 38 to 312 + / - 47 m, p < 0. 05 ; mean difference from the control group, 14 % ; 95 % confidence interval, 9 to 20 %).
