Effects of HIIT vs Strength Training on Health in Postmenopausal Women with Breast Cancer

Postmenopausal Oncological Women Exercising for Recover Their Health. Associations and Changes in Metabolic Flexibility and Autonomic Control After Two Training Programs (Muscle Power vs Metabolic Power): the POWER Health Study

Not applicable Interventional University of Valencia · NCT06336070

What this trial studies

The POWER Health study is a randomized clinical trial designed to evaluate metabolic flexibility and autonomic function in postmenopausal women with a history of breast cancer compared to untreated controls. Participants will undergo two different 8-week supervised exercise interventions: high-intensity interval training (HIIT) aimed at improving metabolic power and strength training focused on enhancing muscle power. The study aims to determine the impact of these interventions on cardiovascular health and overall well-being in this population. By comparing these two approaches, the trial seeks to identify the most effective exercise regimen for improving health outcomes in postmenopausal oncological women.

Who should consider this trial

Good fit: Ideal candidates include postmenopausal women aged 35 to 75 who are either relapse-free from breast cancer or have not been diagnosed with cancer in the last 15 years.

Not a fit: Patients with medical contraindications to exercise or those who have planned surgeries during the intervention period may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved cardiovascular health and quality of life for postmenopausal women with a history of breast cancer.

How similar studies have performed: Previous studies have shown positive outcomes with exercise interventions in cancer survivors, suggesting that this approach may be beneficial, although the specific comparison of HIIT and strength training in this context is novel.
