Float First: An Index of Floating: Factors Affecting Floating in Different Populations

Brief Summary

The study involves measurements of body composition using a DEXA scanner, lung function, buoyancy and floating technique. An understanding of the effects of physiological and anthropometric measures on an individual's ability to float may lead to the creation of a 'Floatability Score' to aid current public information. With this floatability score a set of actions that people of certain body types should adopt in water will be created, to tailor the current public safety messaging in an attempt to ensure more people are aware of how they can float in water

Conditions

Floating Technique; Anthropometry; Lung Function

Keywords

Floating; Sculling; water safety

Outcome Measures

Primary Outcomes (1)

• Floating index

  Describes the actions required to stay afloat

  2 minutes

Secondary Outcomes (6)

• Standing Height

  with the two week study window

• Mass

  with the two week study window - performed at the same time of day as the floating and DEXA scan measurements

• Body composition

  with the two week study window - performed at the same time of day as the floating and DEXA scan measurements

• Lung function

  with the two week study window - performed at the same time of day as the floating and DEXA scan measurements

• Buoyancy

  with the two week study window - performed at the same time of day as the floating and DEXA scan measurements

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Accepting all adults able to give their own consent to participate, the investigators aim to recruit a mixture of participants of different body size, shape, sex and race

You may qualify if:

• All participants who feel confident in water which they can stand up in, aged 18 years and older (18-29 years for Phase 1).
• The participant is willing and able to give informed consent for participation in the study.
• Be able to climb up and down a set of steps to access the swimming flume

You may not qualify if:

• Have allergies to water or chlorinated water.
• The participant is pregnant or suspects they may be pregnant.
• Not able to climb up and down a set of steps to access the swimming flume
