Inspiratory Muscle Training (EMI) on Inspiratory Muscle Strength, Pulmonary Capacity and Performance in Soccer Players

"The inspiratory muscle training program will be of the strength and endurance type, using the POWERbreathe® device and composed of: daily sessions (3 sets of 15 repetitions -inspiration), 6 days a week for 8 weeks. Participants will begin training breathing with a resistance of 20% of their PImax during the first week. After the first week, the resistance will increase between 5% and 10% in each session until reaching 80% of the PImax, which will be maintained during the first month. Upon completion, the PImax value will be re-evaluated and the player will train 80% of this new value during the second month. At the end of the second month, the PImax is evaluated and the player will train the third month with a resistance of 80% of this new value."
