Abstract: Inspiratory muscle training (IMT) has been shown to possibly improve exercise performance, but reports on IMT and running performance are rare. The objective of the present study was to examine the effect of target-flow IMT on running performance in recreational runners. Sixteen healthy recreational runners (five females) were recruited for the present study. They were randomly allocated into either an experimental or control group. Participants in the experimental group underwent a 6-week target-flow IMT programme, while those in the control group underwent a 6-week shoulder circumduction exercise programme. Running performance during a 1,500-m time trial run was assessed before and after the intervention period. After the intervention period, only the experimental group demonstrated an increase in inspiratory muscle strength (by 16.15 ± 7.44 cmH2O; p < 0.05) and reduced completion time in the 1,500-m time trial (by 9.63 ± 5.42 seconds; p < 0.05). Exertion sensation was reduced by 1.63 ± 0.74 points (p < 0.05). No changes were observed in maximal aerobic capacity and pulmonary function in either group after the intervention period. A 6-week target-flow IMT programme enhanced running performance in recreational runners.
