The safety of sportive chokes: a cross-sectional survey-based study
- View All
Objectives: Sportive choking or strangling, known as a 'choke' in the combat sports community, is the practice of compressing the jugular veins and carotid arteries to threaten unconsciousness by lowering cerebral perfusion pressure. This is commonly practiced within combat sports and police/military combatives. The safety profile of sportive choking is underrepresented in the literature. The authors sought to explore the safety of sportive chokes. Methods: A convenience sample of visitors to two combat sports internet forums completed an anonymous web-based survey on choking experience and related symptoms. Descriptive statistics were used to describe the obtained data. Bivariate analysis was performed to elaborate on relationships between grappling experience and the number of times choked, between the number of times choked with pre-syncope/syncope, and between the duration of symptoms and the number of times choked with pre-syncope/syncope. Results: Overall, 4421 individuals completed the survey. One hundred and fourteen were excluded, leaving 4307 analyzed respondents. Ninety-four percent were male, 89.2% were ages 18-44 years. Seventy-nine percent had >1 year of grappling experience and 30% had >5 years. Of the 4307, 1443 (33.5%) reported being choked >500 times, 3257 (75.7%) have been choked to near-syncope, and 1198 (27.8%) have been choked unconscious. Two of the 4307 (0.05%) reported ongoing symptoms from chokes. Of the respondents, 94.3% felt applying a choke would be a safe and effective way to control a street fight; 83.6% felt that vascular neck restraint, the police combative equivalent of sportive choking, would be appropriate as an alternative escalation of force option. Conclusion: Based on a convenience sample of 4307 respondents' self-reported data, sportive choking appears to be safe. Only 0.05% experienced ongoing symptoms, which were likely not related to brain ischemia.
