POWERbreathe - Improves Cycling Performance

• Improved cycling time trial performance by 4.6% - equivalent to slashing 3-minutes off a 40k time trial
• Enabled participants to cycle for 33% longer and with lower sense of effort
• Increased strength of inspiratory muscles by 30 – 50%

POWERbreathe Inspiratory Muscle Training & Cycling

The hunched position adopted during cycling can create breathing problems. The contents of your abdomen (mainly your liver and gut) become compressed and pushed up against your main breathing muscle, the diaphragm. This restricts its normal movement and can make breathing feel much harder.

Research has shown that cycling as little as 20km at race pace induces significant fatigue of the inspiratory muscles (breathing muscles).

POWERbreathe reduces breathing fatigue, improves cycling time trial performance and has a huge ergogenic effect after just six weeks of training.

Train smarter, not harder, to perform better.
