RMT improves endurance and cuts breathlessness
Training your breathing muscles can improve endurance performance, boost breathing muscle strength/endurance, and make efforts feel easier (less breathlessness), including in tough settings like altitude. This comes up repeatedly in the applied review for coaches and is backed by controlled work it summarizes.
LINK TO THE RESEARCH
RMT builds stronger breathing muscles that predict higher VO₂ Max
Across competitive athletes, measures of respiratory muscle strength—especially maximal expiratory pressure (MEP)—were significant predictors in models explaining about 51% of the variance in VO₂max/kg. Translation: the stronger your breathing “engine,” the higher your ceiling for aerobic fitness tends to be.
RMT delays a “blood-stealing” reflex from tired breathing muscles (metaboreflex)
When the breathing muscles fatigue, the body can reflexively redirect blood toward them and away from your legs/arms, which hurts performance. RMT seems to toughen those muscles so they fatigue later, blunting this reflex and helping you keep more blood flow for working limbs.
RMT improves performance across many sports — from endurance to combat disciplines
Across multiple studies, respiratory muscle training (RMT) produced measurable improvements in both aerobic and anaerobic sports. Swimmers increased their underwater distance and stroke efficiency after inspiratory training, while cyclists and runners experienced faster recovery and reduced perceived effort during intense exercise. Even athletes in strength and endurance hybrid disciplines like judo and cross-country skiing showed that stronger breathing muscles correlated with higher VO₂ max and greater power output. In simple terms, whether it’s long races or short explosive bouts, stronger lungs consistently translate into better performance.
RMT strengthens the diaphragm and core, improving posture and movement
Slow, controlled breathing through trained muscles doesn’t just affect performance — it also improves recovery and mental calm.
RMT enhances parasympathetic activation (the “rest and recover” system), helping athletes relax faster, sleep better, and manage pre-race stress.
RMT strengthens the diaphragm and core, improving posture and movement
Respiratory Muscle Training (RMT) improves how efficiently you breathe when oxygen demand is high — like during intense workouts, sprints, or training at altitude. Research shows that athletes with stronger respiratory muscles use less oxygen for the same effort, meaning their bodies stay calmer and more efficient under stress. This training delays the point where you start gasping for air, maintains steadier oxygen delivery to your working muscles, and keeps fatigue at bay for longer. In short, RMT helps you stay in control of your breathing — and your performance — even when the pressure peaks.
