研究概览
简要总结
This study examines how different phases of the menstrual cycle are associated with selected performance and musculoskeletal parameters in physically active women aged 18-35 years.
Participants will track their menstrual cycle using a mobile app for approximately 2 months and attend 3 laboratory visits scheduled to specific cycle phases.
At each visit, participants will complete non-invasive assessments including lower-limb strength/performance testing, musculoskeletal measurements (muscle and tendon properties), body composition assessment, and symptom-related questionnaires.
The goal is to improve understanding of physiological variability across the menstrual cycle and support evidence-based planning of training, testing, and clinical practice in women.
详细描述
Background and rationale:
Female physiology changes across menstrual cycle phases, which may influence neuromuscular performance, perceived symptoms, and selected tissue/mechanical properties. Current evidence is heterogeneous, partly due to methodological differences in cycle-phase identification and measurement protocols. This study aims to provide standardized data from repeated within-subject assessments across the menstrual cycle.
Objectives:
Primary objective is to evaluate associations between menstrual cycle phase and selected performance-related outcomes in physically active women.
Secondary objectives are to explore phase-related differences in musculoskeletal parameters, body composition outputs, and self-reported symptoms.
