Experimental: Inspiratory Muscle Training
Inspiratory Muscle Training intervention (Sham-IMT) groups during a 3 months training season. A pressure threshold device (POWERbreathe - HaB International Ltd., UK) will be used to IMT. The IMT group will perform 30 inspiratory efforts, 5 times a week, twice daily, for 12 weeks, against a pressure threshold load equivalent to 50% of maximal inspiratory pressure (MIP).
Other: Inspiratory Muscle Training
The Inspiratory Muscle Training (IMT) group will perform 30 inspiratory efforts, 5 times a week, twice a day, for 12 weeks, against a pressure threshold load equivalent to 50% of maximal inspiratory pressure.
Sham Comparator: Sham Inspiratory Muscle Training
Sham-IMT group will follow a similar protocol, except the inspiratory effort that will be made against 15% MIP. The duration of each IMT session will be 30 inspirations. After the initial setting of training loads, the IMT group will be instructed to periodically increase load so that only 30 maneuvers could be completed. The Sham-IMT group will not receive these instructions. All the IMT sessions, in both groups will take place before swimming training and will be supervised throughout the intervention period to ensure that technique and load will be appropriate.
Other: Sham Inspiratory Muscle Training
The Sham Inspiratory Muscle Training (Sham-IMT) group will perform 30 inspiratory efforts, 5 times a week, twice a day, for 12 weeks, against a pressure threshold load equivalent to 15% of maximal inspiratory pressure.
