The science of RMT - Respiratory Muscle Training, or Athletic Lung Trainers is proven and accepted for medical purposes as well as for athletics. RMT devices started marketing to athletes over the past decade. The biggest obstacle in using RMT for athletes, is that most devices can't be comfortably or safely used during practices or daily training routines. Thus you cannot mimic normal sports specific physiologic ventilatory demands, let alone improve on these demands. Most RMT devices need to be used separate sessions apart from practicing, training, conditioning, etc.
Traditional RMT Devices are bulky to use as you typically have to hold device hand to mouth to utilize. Certainly not conducive for athletes to use while practicing, training, etc. Because you cannot use traditional RMT devices while practicing, you can't mimic sport specific ventilatory demands, nor improve upon those sports specific demands. There are two other devices designed for sports, however, neither device can be worn under helmet face-mask in hockey, football or lacrosse, nor do they fit comfortably in mouth like mouthguard. The Training mask product can make you feel claustrophobic and not very pragmatic in the design for most athletes.
Athletic Lung Trainer is designed to be worn while you practice your specific sport. It fits into your mouth like a mouthguard allowing you to exercise your lungs during practices, conditioning sessions, weight training, etc. Thus giving your lungs a sport specific physiologic lung training workout based upon your actual sport. Stealth was designed to be worn and used comfortably and safely under helmet face-masks, regardless of sport.
Athletic Lung Trainer employs an adjustable dual airflow resistance system which allows users to breath at full capacity, or dial up resistance incrementally over time. This allows athletes to start at low resistance levels, increasing resistance over time allowing the lungs to adjust, similar to weight training.
