Key finding
V̇O2 peak increased by 0.42 mL/kg/min per hour of endurance exercise/week (95% CI: 0.17–0.66, p = 0.001).
This study evaluated the impact of a telemedicine-supported home-based exercise intervention on V̇O2 peak in older patients with coronary heart disease and type 2 diabetes, finding that exercise duration significantly influenced improvements.

Study focus
This study evaluated the impact of a telemedicine-supported home-based exercise intervention on V̇O2 peak in older patients with coronary heart disease and type 2 diabetes, finding that exercise duration significantly influenced improvements.
This study underscores the importance of exercise duration for older adults with coronary heart disease and type 2 diabetes. By focusing on longer exercise sessions, healthcare providers can better tailor interventions that enhance cardiovascular fitness, potentially leading to improved health outcomes and quality of life for these patients.
Effectiveness of the intervention remains unclear due to limited sample size. Findings may not be generalizable to younger populations or those without comorbidities. Potential confounding factors were not fully controlled in the study design.

V̇O2 peak increased by 0.42 mL/kg/min per hour of endurance exercise/week (p = 0.001).
A 10% increase in exercise intensity was associated with a 0.26 mL/kg/min increase in V̇O2 peak (p = 0.05).
Longer training duration in the first 2 weeks was linked to higher adherence over 6 months (OR of 1.09, p = 0.001).
