Precise load settings may vary due to: (1) the analogue nature of the calibrated spring tensioner and the precision with which the load is selected; (2) a small effect of inspiratory flow rate upon spring compression such that high inspiratory flow rates lead to greater spring compression, and a small increase in load.
This effect is common to all spring loaded devices, and its size is magnified by increasing spring range (it is larger in a spring with a maximum range of 90cmH2O compared with one with half this range), it is also greater at lower absolute load settings.
POWERbreathe is a scientifically proven Inspiratory Muscle Training (IMT) device, developed by leading scientists for improving the strength and endurance of the muscles used to breathe in, primarily the diaphragm and intercostals / rib cage muscles.
As with any other muscle, respiratory muscles can be trained so that they are more resistant to fatigue. This resistance to fatigue results in reduced breathlessness and enhanced exericse tolerance.
POWERbreathe Classic uses scientifically proven Pressure Threshold Training. This provides a specific and consistent pressure to train against. When breathing in through POWERbreathe the load calibrated spring provides the resistance.
POWERbreathe is drug free, suitable for almost anyone and should cause no harmful side effects when used properly. Please read the following precautions and contraindications to ensure that you use your POWERbreathe safely and appropriately.
If you have any doubts about POWERbreathe’s suitability, or you have a medical condition, please consult your doctor.
Inspiratory muscle training, such as training with POWERbreathe, is not recommended for patients with certain conditions, including the following:
