Abstract

To determine changes in lung function following an acute bout of high intensity interval exercise (HIIE), moderate intensity interval exercise (MIIE), and moderate intensity continuous exercise (MICE) in adults with airway hyper-responsiveness (AHR). A randomized cross-over design was used. Participants completed five laboratory sessions: (1) eucapnic voluntary hyperpnea challenge (2) maximal exercise test to determine peak power output (PPO) and, (3-5) HIIE (90% PPO for 1min followed by 10% PPO for 1min, repeated 10 times), MIIE (65% PPO for 1min followed by 10% PPO for 1min, repeated 10 times) and MICE (65% PPO for 20min). Lung function was assessed pre and post-exercise. Thirteen participants (age: 21.1±2.7years) with mild/moderate asthma completed all protocols. Lung function was significantly lower following the MICE (-14.8%±12.2) protocol compared to the HIIE (-7.1%±8.3) and MIIE (-4.5%±3.3). It appears that MICE is associated with the greatest decline in post-exercise FEV1 among those with AHR. Interval exercise may be better tolerated than continuous exercise among those with AHR.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
