Attenuated Pressor and Sympathetic Neural Responses to Exercise in Long-Term Breast Cancer Survivors: Role of the Muscle Metaboreflex

Key Points

• This study aims to explore how exercise affects blood pressure and the nervous system in long-term breast cancer survivors.
• Assessments focused on pressor responses and sympathetic neural activity during exercise.
• Comparison made between breast cancer survivors and control groups.
• Evaluated muscle metaboreflex as a potential explanatory mechanism.
• Found that pressor and sympathetic responses to exercise were significantly reduced in breast cancer survivors.
• Indicated that impaired muscle metaboreflex contributed to these reduced responses.
• No significant differences were observed in heart rate or total peripheral resistance.
