Conditions

Athletes with chest breathing pattern.

Interventions

Intervention 1: Intervention group: Group A: for 6 weeks and 3 days a week (18 sessions), they will be subjected to the intervention of breathing exercises using the POWERbreathe device (POWERbreathe
International Ltd, England, United Kingdom). Each training session will include a 5-minute warm-up (15% maximal inspiratory pressure (MIP)) and two sets of 15 repetitions of breathing with an interval
