Blood Flow Reserve: Effects After Training With Heavy Inspiratory Exercises

Participants will use the POWERbreathe KHP2 inspiratory muscle training device. All participants will be assigned to perform 30 inspiratory maneuvers (5 sets of 6, 1-minute rest between sets), 6 days per week, for 6 weeks. Participants will be trained at 55% PIMAX during week 1, 65% PIMAX during week 2, and 75% PIMAX during weeks 3 to 6.
