Abstract
[Purpose] This study investigated differences in respiratory function between exercise and non-exercise in a supine position maintained with a foam roller. [Subjects and Methods] The participants were 45 healthy students (22 males; mean age, 21 years; body mass index, 21.4 kg/m2). They were randomly divided into three groups: those who exercised in the supine position on a foam roller (EX group), those who maintained the supine position on a foam roller (non-EX group), and the controls. Forced vital capacity (FVC), transversus abdominis muscle thickness, and chest and abdominal wall mobilities were measured. The measurements were conducted before and after the intervention period. [Results] FVC in the non-EX group, and abdominal wall mobility in the EX group significantly increased after the intervention. [Conclusion] The results suggest the supine position on a foam roller increases the respiratory function.
