Description

In this study we examined the potential benefits of incentive spirometry respiratory training on the ventilatory function of healthy women. Participants did 4 sets of breathing exercises a day, with half the participants doing 10 repetitions per set and the other half doing 30. Each group was further subdivided into training periods of 2, 4, 6, 8, or 10 days. The participants’ ventilatory function was measured at the beginning and end of the training period with an electronic spirometer. We found that when pre- and post-training breathing capacity and vital capacity as percent of predicted were compared, a significant increase was seen in both the 10 reps/set/10-day group and the 30 reps/set/10-day group, but that the increase was significantly larger in the 30 reps/set/10-day group. In addition, peak expiratory flow rate for the 30 reps/set/10-day group significantly increased. These results suggest that, for incentive spirometry breathing exercises, more than 10 reps per set are necessary to significantly improve ventilatory function, and that an improvement in breathing capacity does not necessarily require a high frequency of exercises.
