Research has highlighted flotation-REST as a promising method for relaxation and performance enhancement in sport; however, to further evaluate the use of flotation-REST in an athletic environment, additional research is warranted. Semi-structured interviews were conducted with six elite track and field athletes about their experiences and perceived effects of flotation-REST. Athletes were interviewed twice; once for their immediate response and again to explore their perceptions of flotation-REST over time. The data was analyzed using interpretative phenomenological analysis. Flotation-REST was perceived as pleasant and relaxing. Five athletes reported less stress and an overall increase in well-being for one or two days afterwards, although they felt physically tired during training sessions. Being in a better mood, placing fewer demands on themselves, and feeling more optimistic and present were also perceived effects. This study shows the potential of flotation-REST as a technique for health promotion, stress management, and a means to practise mindfulness. ABSTRACT FROM AUTHOR
