Abstract

Respiratory muscle stretch gymnastics (RMSG) are designed to decrease chest wall stiffness, reduce dyspnea at rest and improve the quality of life. The focus of this study was to determine whether a RMSG program affects the psychological state of healthy subjects. A previous study showed that there is a positive correlation between anxiety level and respiratory rate (RR). We hypothesize that RMSG will decrease the RR related to alterations in anxiety or other factors that are associated with the quality of life in healthy children. Forty-four primary school children living in Tokyo participated in the study and were randomly assigned to either gymnastics or control groups. Baseline assessment of both groups included completion of the Questionnaire for Measuring Health-Related Quality of Life in Children (Kid-KINDL) and the State-Trait Anxiety Inventories for Children (STAI-C). RRs were recorded initially and the children in the gymnastics group were instructed on how to perform RMSG. The RR was measured again and the participants completed the state anxiety scale. The gymnastics group was told to perform the gymnastics once a day for one week, whereupon post-testing using the testing protocol used for the baseline measurement was performed again on both groups. RR and anxiety level significantly decreased while Kid-KINDL increased after one week of RMSG in high trait anxiety subjects of the gymnastics group. We suggest that the decrease in RR after RMSG reduces anxiety levels in children, and contributes to an improvement in their Kid-KINDL score.
