Key result
Three different CrossFit sessions linked to similar reductions in HRV and post-exercise SBP.
Why the study?
To verify heart rate variability and blood pressure acute responses during and after three sessions of CrossFit.
What are the acute responses of heart rate variability and blood pressure during and after three different CrossFit sessions in experienced subjects?
Population
Nine subjects with more than one year of experience
Comparison
Three different sessions of CrossFit

Acute autonomic responses may be consistent across CrossFit sessions in experienced athletes; hypothesis-generating and leaves open effects in novices or long-term CV outcomes.
Observational (n=9)
What are the acute responses of heart rate variability and blood pressure during and after three different CrossFit sessions in experienced subjects?
p-value: p=<0.001
Different CrossFit sessions induce similar acute autonomic nervous system responses, characterized by reduced HRV and post-exercise hypotension.
Barreto et al. (2022) conducted an observational in CrossFit practitioners (n=9). CrossFit sessions was evaluated on Heart rate variability and blood pressure (p=<0.001). Three different CrossFit sessions induced similar reductions in heart rate variability (HF, p<0.001) and post-exercise systolic blood pressure (p<0.05) among experienced practitioners.
