BACKGROUND: Physiological and psychological markers of @entity1 with @entity712 ( @entity712 ) who will respond to aerobic training are needed as a guide to appropriate therapy. METHODS: Seventeen of 21 @entity1 with stable @entity712 completed a 16-week supervised progressive walking program 5 times per week. Cycle ergometer determinations of peak @entity26 intake and peak power output at entry and 16 weeks were supplemented by a 6-minute walk, a disease-specific Quality of Life (QOL) questionnaire, and a standard gamble. RESULTS: Peak @entity26 intake increased by 2.6 +/- 1.5 mL/(kgmin) over an initial value of 15.6 mL/(kgmin), with parallel gains in peak power and the 6-minute walk. Marked improvements in QOL and standard gamble scores also developed. Initial @entity159 (heart volume, ejection fraction, @entity26 pulse, and peak @entity26 intake) was correlated more closely (P = 0.09 to 0.18) with delta peak @entity26 intake than with delta peak power or delta walking distance. Physiological gains bore little relationship to @entity1613 . Gains in @entity712 Questionnaire and Standard Gamble scores were strongly associated with initial scores for these variables ( @entity1353 , P = .02; mastery, P = .005; standard gamble, P = .001), but could not be predicted from either initial physiological status or gains in physiological condition. CONCLUSIONS: Initial @entity159 provides little indication of which @entity1 with @entity712 respond well to training. Gains in QOL score are influenced by initial scores, and seem to show a "ceiling" effect.
