Breathe better and get fitter

Breathlessness is a common feature of lung and heart disease, but as we know all too well, it’s also a feature of normal exercise. Research has shown that the strength of the inspiratory muscles has a direct influence on how hard we can breathe and how breathless we feel whilst doing it.

If the muscles are weakened or fatigued (inspiratory muscles can fatigue by as much as 20%) then we can’t breathe as hard and breathing requires greater effort; we experience the effort as breathlessness.

Think about how much heavier a dummbbell feels on the 12th repetition than it did on the first. In the same way, if the inspiratory muscles are weakened or fatigued, breathing feels harder.

All is not lost though. POWERbreathe Inspiratory Muscle Training will help as it exercises your breathing muscles to make them stronger and more resistant to fatigue! And because your breathing stamina increases, your sports performance will improve and you’ll be able to exercise for longer with less effort.

Influence of Gender and Inspiratory Muscle Training on the Perception of Dyspnea in Patients With Asthma

“Men and women respond differently to asthma. Maximal inspiratory mouth pressure (PImax), ?2-agonist consumption, and perception of dyspnea (POD) were measured in 22 women and 22 men with mild persistent-to- moderate asthma. Next, the women were randomized into two groups: those who received inspiratory muscle training and those who received sham training. The training ended when the PImax of the training group was equal to that of the male subjects. POD was then measured once again.”

Conclusion:

“Our study shows that the inspiratory muscles in women could be trained within 20 weeks to reach the same strength as in their male counterparts. This increase in inspiratory muscle strength completely concealed the gender differences in POD and ?2 -agonist consumption, suggesting that the gender differential in maximal inspiratory muscle strength is responsible for the fact that women are more symptomatic than men. However, other possibilities for the gender differences could not be negated in our study, and further investigations are needed to completely clarify the issue.”

Sex Differences In Intensity And Qualitative Dimensions Of Exertional Dyspnea In Physically Active Young Adults

“Understanding sex differences in the qualitative dimensions of exertional dyspnea may provide insight into why women are more affected by this symptom than men. This study explored the evolution of the qualitative dimensions of dyspnea in 70 healthy, young, physically active adults.”

Conclusion:

“Findings suggest that men and women do not differ in their perceived quality of dyspnea during submaximal exercise, but subjective differences appear at maximal exercise and may be related, at least in part, to underlying sex differences in breathing patterns and operating lung volumes during exercise.”
