Table 4: Quality of life (Minnesota Living with Heart Failure Questionnaire) in the circuit and interval training groups at baseline and after 6 weeks’ training (median and range). The median and range value for change from baseline to post-training is also shown. There were no significant differences between groups in changes from baseline to post-training.
