SD = standard deviation; 6MWT = six-minute walk test; n = number; 6MWD = six-minute walk distance; m = metre; % pred = percentage of predicted value; SpO2 = oxygen saturation; PR = pulse rate; RPE = rate of perceived exertion; ICT = incremental cycle test; W = watts; VO2peak % pred = percent of predicted normal maximal oxygen uptake; VE = minute ventilation; MVV = maximal voluntary ventilation; HRQoL = health-related quality of life; SGRQ = St George’s Respiratory Questionnaire; METs = metabolic equivalent; EE = energy expenditure; cal = calorie.
* Predicted PR = 220 - age.
