Different Resistance Training Intensity Prescription and Monitoring Methodologies: Effects on Strength, Body Composition, and Well-being in Survivors of Breast Cancer

Effects of Different Methods of Prescription and Monitoring of Resistance Training Intensity on Muscle Strength, Body Composition, and Psychological Well-being in Survivors of Breast Cancer

The goal of this clinical trial is to compare the effects of three different methods of prescribing and monitoring resistance training intensity on muscle strength, body composition, quality of life, fatigue, anxiety, and depression in breast cancer survivors.

Breast cancer survival rates have significantly increased in recent years, highlighting the importance of effective interventions to address the long-term consequences of cancer and its treatments. Breast cancer survivors often experience muscle weakness, changes in body composition, fatigue, and psychological distress, which can negatively impact their quality of life. Resistance training has been widely recognized as a safe and effective strategy to counteract these effects, improving muscle strength, body composition, and psychological well-being.

Despite its benefits, the optimal method for prescribing and monitoring resistance training intensity in breast cancer survivors remains unclear. Traditional methods based on one-repetition maximum (1RM) testing may not fully account for individual variations in fatigue and performance. Alternative approaches, such as load-velocity relationships, allow for more precise and real-time adjustments to training intensity, potentially optimizing outcomes.

This randomized controlled trial aims to compare the effects of three different methods of resistance training intensity prescription and monitoring on muscle strength, body composition, quality of life, fatigue, anxiety, and depression in breast cancer survivors. The findings will contribute to developing evidence-based exercise guidelines, enhancing rehabilitation strategies and overall well-being in this population.
