CrossFit is characterized by the combination of strength exercises, gymnastics, and cardiovascular conditioning, organized into sessions with different intensities and structures. This study aimed to analyze scientific evidence regarding acute heart rate and blood pressure responses during and after CrossFit sessions. An integrative literature review was conducted using the PubMed/MEDLINE, Virtual Health Library (VHL), and SciELO databases, employing descriptors related to CrossFit, heart rate, and blood pressure. A total of 61 records were identified, of which nine studies met the eligibility criteria. The findings demonstrated high cardiovascular demands during workouts of the day (WODs), with heart rate values frequently approaching or exceeding 90% of maximum heart rate. Exercise organization, duration, and workout structure influenced the magnitude of cardiac responses. However, only two studies directly investigated blood pressure, identifying specific changes according to the workout protocol performed. Evidence regarding cardiovascular recovery was also limited due to differences in assessment timing. The predominance of small samples and trained participants restricted the generalizability of the findings. It was concluded that acute cardiovascular responses to CrossFit vary according to WOD characteristics, highlighting the importance of individualized exercise intensity monitoring. Further investigations with greater methodological standardization are needed, particularly regarding blood pressure behavior and post-exercise cardiovascular recovery.
