In the study, Dr Lomax used an inspiratory muscle training device which works in a similar way to other resistance training devices to build muscle strength.
For inspiratory muscle warm-up, because the power-boosting effect of warm-up exercises typically dissipates within half an hour, an athlete would use the device to do two sets of 30 breaths immediately before the sporting event for best results.
Dr. Mitch Lomax and her team at the Department of Sport and Exercise Science at the University of Portsmouth have determined that training of your inspiratory muscles the muscles responsible for breathing in can lead to significant improvements in athletic performance.
