Runners, bikers and swimmers – surely you have noticed when you are running harder, or for an extended period of time, your leg muscles become fatigued. However, it’s not necessarily your leg muscles that are the first to become strained. When you run, bike and swim, it is more likely that your respiratory muscles are the first to become tired. It is important to remember that respiratory muscles are just as susceptible to overexertion as your body’s other muscles.
While you’re running and you feel your legs become fatigued, this is because the nervous system has redirected oxygen delivery to your respiratory muscles to keep them going and to not allow them to become fatigued to a dangerous extent. When your limb muscles do not have enough oxygen, they become tired and start to feel limp and heavy.
To increase your respiratory muscle endurance, you can train the muscles with deeper breathing to strengthen them. They can be trained separately from the rest of your body. Using a respiratory trainer like Breathslim, you’ll use your respiratory muscles at a higher capacity, sometimes even more than when you’re actually running, biking or swimming. Without the rest of your body needing excessive oxygen, the tool helps strengthen in the chest cavity.
With stronger respiratory muscles, your endurance and athletic performance will take off.
