Results revealed in a research paper published in the Journal of Strength and Conditioning has revealed that “the combination of IMT and cycling may provide an additive training effect.”
The POWERbreathe KH1 Inspiratory Muscle Training Device was used in this research that looked at acute activation of the diaphragm and sternocleidomastoid in combination with cycling.

Purpose of the Study:
To determine the effect of IMT (Inspiratory Muscle Training) on respiratory muscle EMG-activity during stationary cycling in the upright and drops postures as compared to IMT performed alone.
“We chose to use an IMT of 40% MIP so as to minimize inspiratory muscle fatigue. MIP was measured with an electronic IMT device (POWERbreathe KH1) that could then be set at a fixed training load of 40% MIP.”
… “The Mayo Institutional Review Board approved all methods and procedures, including the use of human subjects.”
“Previous studies have demonstrated that IMT at 50-80% intensity of MIP results in diaphragm strength and endurance gains (4, 6, 7). The present study explored whether combining a non-fatiguing IMT intensity (40% IMT) with cycling would significantly increase respiratory muscle recruitment and activity. In agreement with our hypothesis, we observed that IMT at 40% MIP plus cycling produces significantly greater EMG activity than IMT alone. This suggests that cycling plus IMT may provide an additive training effect as compared to traditional IMT training.”
“Cyclists can therefore use IMT while cycling as an additional method to train. This might be especially useful when a cyclist is limited in workload due to recovery from a lower extremity injury and desires to maintain respiratory fitness.”
