May inform exercise capacity assessment in post-CR CHD patients; hypothesis-generating for self-efficacy interventions needing prospective validation.
Cross-Sectional (n=130)
Age, female sex, body mass index, and exercise self-efficacy are significant determinants of exercise capacity in postcardiac rehabilitation patients with coronary heart disease.
Chair et al. (2022) conducted a cross-sectional in Coronary heart disease (n=130). Age, sex, body mass index, and exercise self-efficacy was evaluated on Exercise capacity (10-metre incremental shuttle-walk test). Age (β=-.42), female sex (β=-.35), body mass index (β=-.25), and exercise self-efficacy (β=-.20) were significantly associated with exercise capacity, explaining 56.5% of its variance.
