Introduction: The floor exercise during Women's Artistic Gymnastics is the topic for this study. The physiological parameters of gymnastics reflect changes in heart rate (HR), which are directly related to the activity of the autonomic nervous system (ANS), as a consequence of parasympathetic withdrawal and sympathetic activation, among other factors. Aerobic performance represents a protective physiological adaptation against physical and psychological stress, contributing to greater performance during exercise. Objective: Describe and analyze the HR responses of female artistic gymnastics athletes during competition, on the floor exercise. Methods: The experiment was carried out at the Training Center (CT), CEFAT/FUNESP during the period of November 2021 and December 2022, with assessment of body composition and cardiorespiratory performance in the shuttle run test. Additionally, a competition was held in which the athletes' performance on the floor exercise and their HR responses were recorded with continuous monitoring throughout the competition. Results and Discussion: The descriptive values of the 9 athletes are shown as mean ± SD, age: 11.7±1.21 years, weekly training hours: 19.6±0.88 h/week, fat percentage: 14.1 ±6.58%, estimated maximum oxygen consumption: (VO2max): 47.2±2.99 ml·min-1·kg-1, final speed (FS): 10.5 ±0.63 km/h, average HR: 172.4±12.2 bpm, peak HR: 191.5±10.6 bpm, area under the curve (AUC): 0.1733±0.04 a.u. The physical demand was determined from the final speed of the running test and fat percentage, through the Z score. Conclusion: In general, the values presented for the HR responses were higher as the physical demands of the athletes were higher, thus not confirming the initial hypotheses.
