AIM: The aim of the study was to evaluate the effects of a 4-week specific Inspiratory Muscle Training (IMT) on young athletes, who practiced basketball at a competitive level.
METHODS: Twenty-nine male basketball players (age: 21±2 years; body mass: 75.31±11.84 kg; stature: 181.28±9.55 cm; BMI: 22.79±1.90 kg∙m-2) attending the University of Rome “Foro Italico” (Rome, Italy) volunteered to participate in the study and were randomly divided in two groups: the intervention group (N.=15) and the control group (N.=14). The intervention group underwent a four week protocol consisting of an IMT carried out through a resistive breathing device (POWERbreath Kinetic Health K3, HaB International©) while athletes randomized to the control group did not underwent any respiratory training. All the athlete underwent several measurements pre- and post-intervention in order to evaluate their exercise capacity, lung function at rest and after a physical effort, their maximal inspiratory pressure (MIP) and other parameters estimated through a medical resistive instrument.
RESULTS: After 4 weeks no statistical differences were observed in subjects’ pre- and post-exercise capacity neither in lung function parameters with the except of a significative increase in peak inspiratory flow (30%) and in maximum voluntary ventilation (7%) in the intervention group. The MIP values significantly increase (30%) only in the intervention group as well as the breath test parameters (flow: 27%; volume: 17%; S-Index: 26%). No significant improvements in the perception of muscular fatigue neither in the perception of difficulty performing spirometry after exercise were found, while a significant decrease of the perception of respiratory fatigue (-31%) was registered in the intervention group. These results are further highlighted by the significant increase in the training session respiratory parameters of the intervention group (load: 29%; T-Index: 32%; volume 39%, power: 93%).
CONCLUSION: The present study shows that a 4 weeks IMT protocol bring to improvements in strength and in endurance of respiratory muscles acting on a reduction in respiratory muscle fatigue, delaying restriction metabolic reflex and so giving to skeletal muscles a greater energy availability.
