Overview

Crossover analysis shows high-intensity interval exercise alters heart rate variability in women, suggesting cycle phase influences outcomes.

Key Points

  • This research aims to analyze heart rate variability and blood metabolism during specific menstrual cycle phases following exercise.
  • Crossover design study involving 10 healthy adult women with normal menstrual cycles.
  • Participants performed high-intensity interval aerobic exercise across menstrual cycle phases: menstrual, follicular, ovulation, and luteal.
  • Measurements included heart rate variability and metabolic indices before, immediately after, and 30 minutes post-exercise.
  • Heart rate variability metrics (SDNN, LF, HF) decreased immediately after exercise but recovered by 30 minutes.
  • LF/HF ratio increased immediately after exercise in all phases but decreased by 30 minutes in follicular, ovulation, and luteal phases.
  • Blood triglycerides increased immediately post-exercise in the menstrual phase but decreased after 30 minutes.
