Body fat percentage is the primary factor influencing float outcome, and with appropriate instruction and practice, individuals of African, Caribbean and Asian heritage can 'find their float', suggesting floating is a learnable competence.
The majority of participants of African, Caribbean, Asian, or mixed heritage successfully completed a two-minute supine float after instruction and practice.
Body fat percentage strongly correlated with buoyancy and floating outcome.
Bone mineral density showed weak or no association with float outcome in participants of African, Caribbean, and Asian heritage.
Passive floaters demonstrated greater buoyancy and less exertion than active floaters.
Many unintended drownings are linked to the initial cardio-respiratory responses to cold-water immersion (cold shock) within the first two minutes of immersion.
The findings indicate that floating is a learnable competence and highlight the need for integrated drowning prevention strategies.
This research suggests that people of African, Caribbean, and Asian heritage can learn to float in water with proper instruction and practice, challenging some earlier assumptions about why people from these communities may struggle to stay afloat. The study tested 96 participants from these communities in a supervised two-minute back float, and found that about 93% were able to successfully complete it after receiving guidance. Importantly, the study found that body fat percentage — not bone mineral density (BMD), which had been previously suggested as a key factor — was the strongest predictor of whether someone floated easily and how buoyant they were. The research also found that some participants floated passively (without needing to move at all) while others needed to make purposeful movements to stay afloat, and passive floaters tended to be more buoyant and exerted less effort. The study situates these findings in the context of drowning prevention: in cold water, people experience an involuntary breathing response in the first two minutes that can cause them to inhale water, and floating calmly rather than struggling to swim can be a life-saving response during this critical period. This research suggests that floating should be viewed as a teachable skill rather than a fixed physical ability, and that tailored, community-based drowning prevention programs could help address the higher drowning risks faced by people of African, Caribbean, and Asian heritage. The authors call for co-produced, accessible interventions that engage these communities directly, combining practical floating instruction with broader public health drowning prevention campaigns to reduce inequities in water safety.
