Optimizing basal body temperature measurement for cycle diagnostics: a comparison of different methods in female recreational athletes.

ABSTRACT:

Introduction

Accurate detection of ovulation is essential for menstrual cycle-based training periodization for female athletes. Although body temperature tracking is a non-invasive method for this purpose, its reliability can vary depending on the measurement site and timing. This study aimed to compare the utility of different body temperature measurement methods and measurement times for ovulation detection.

Methods

Seventeen recreationally active women tracked one menstrual cycle (October 2023 to February 2024) using continuous intravaginal core body temperature measurement as the reference method. Additional temperature measurements (sublingual, rectal and external ear) were taken at two points in time: 6 a.m. and upon waking. Ovulation was additionally confirmed using l
