The Effect of the Menstrual Cycle on Immune Cell Activity and Recovery After Resistance Exercise (NCT06985420)
The Impact of the Menstrual Cycle on Innate Immune Cell Activation, Recruitment, and Adhesion Dynamics During Recovery From Damaging Resistance Exercise: Role of Neutrophils and Systemic Chemokines.
🩺 Plain-English Summary (8th-Grade Level)
The goal of this observational study is to learn how the menstrual cycle affects immune cell activation, recruitment, and recovery responses after resistance exercise in healthy, resistance-trained women aged 18-40. The main questions it aims to answer are: Does the menstrual cycle influence neutrophil recruitment and adhesion after resistance exercise? Does the menstrual cycle affect markers of muscle damage and functional recovery? Researchers will compare three menstrual phases (early follicular, late follicular, and mid-luteal) to see if immune responses and recovery outcomes differ across these phases. Participants will: Complete resistance exercise protocols across three different menstrual cycle phases. Provide blood samples to assess immune cell activation and muscle damage markers. Track sleep, mood, and recovery with questionnaires and wear an accelerometer.
