Exercise can serve as recreational pastime, improve fitness, help to reduce weight, or represent the core activity of professional athletes. Independent of the goals of exercise, one fundamental rule of exercise states that muscles must be trained to improve performance. While this rule applies to all muscles of the body, the respiratory musculature is often overlooked. Strengthening your respiratory power by RMT can however greatly contribute to improving exercise capacity and peak performance – and may just provide that little, but crucial advantage in professional sport.
Here is why respiratory muscle performance is critical for exercise, what impact RMT has had on the performance of athletes, and how RMT can be included into training routines.
What can the Breather do for athletes?
- The limit of exercise tolerance – in athlete and patient alike – is determined by local muscle discomfort, dyspnea and fatigue, with dyspnea being the greatest contributor to exercise cessation. The reason for both muscle pain and dyspnea is a failure of the cardiorespiratory system to deliver adequate oxygen to support the current metabolic requirements of the muscles involved .
- Respiratory muscle training (RMT) improves exercise-limiting dyspnea and delays time to fatigue in healthy people and athletes [2–4].
- RMT enhances performance by improving respiratory muscle endurance, maximal sustainable ventilatory capacity (MSVC) and maximal voluntary ventilation (MVV) .
- Combining RMT with other training modules such as HIIT further enhances the effects of training, as measured by core strength and endurance, onset of blood lactate accumulation, endurance running performance and economy in recreational runners .
- Exercise underwater requires increased respiratory work due to hydrostatic pressure differences across the chest wall. RMT improves endurance of fin swimmers and significantly improves surface and underwater swim times .
- A systematic review and meta-analysis of the effect of RMT on endurance performance confirmed effectiveness of RMT, particularly of combining inspiratory and expiratory muscle training  – the Breather is the first device to offer both IMT and EMT.
- Studies have shown that respiratory muscle training (RMT) improves oxygen uptake, VO2max and ventilatory efficiency, improving aerobic fitness [8–12].
- RMT was also shown to improve the blood flow to resting and exercising limbs, delaying the metaboreflex, thereby improving exercise capacity and endurance .
- RMT strengthens the diaphragm and improves posture and proprioceptive use, for better balance and injury prevention .
How to use the Breather to boost performance
- The Breather is intended for moderate to high-intensity RMT in healthy adults and athletes. RMT is recommended at 70% to 80% of MIP for 2 to 3x 10 breaths, twice a day.
- In addition, using RMT to warm up respiratory muscles before high-intensity exercise can significantly improve time to exhaustion. The protocol has to be determined individually for this purpose 
Integrating RMT using the Breather into your training schedule will boost your performance, fuel your body with oxygen and decrease the time to fatigue.
