Recent studies show that endurance training of respiratory muscle (RMET) improves exercise performance and decreases ventilation (VE) during exercise. Purpose: To evaluate the effect of RMET with normocapnic hyperpnoea (Spirotiger®) on respiratory function, ventilatory efficiency, cycling and running performance in triathletes. Methods: 20M triathletes (age 21-45) were randomly allocated to two groups: RMT group (10) and control group (10). At baseline (T0) athletes underwent respiratory function tests and maximal incremental cardiopulmonary tests performed with both cycle ergometer and treadmill; the same protocol was repeated after five weeks (T1). The RMT group trained at home for five weeks for 20 min daily, seven days a week. Between T0-T1 the daily training program didn’t change. Results: In the RMT group maximal inspiratory pressure (MIP) significantly increased (T0: 8.9±2.4, T1: 9.4±2.1 kPa; P < 0.05) and an improvement of maximum workload (T0: 389±106 T1: 429±119W.

Abstract
Recent studies show that endurance training of respiratory muscle (RMET) improves exercise performance and decreases ventilation (VE) during exercise. Purpose: To evaluate the effect of RMET with normocapnic hyperpnoea (Spirotiger®) on respiratory function, ventilatory efficiency, cycling and running performance in triathletes. Methods: 20M triathletes (age 21-45) were randomly allocated to two groups: RMT group (10) and control group (10). At baseline (T0) athletes underwent respiratory function tests and maximal incremental cardiopulmonary tests performed with both cycle ergometer and treadmill; the same protocol was repeated after five weeks (T1). The RMT group trained at home for five weeks for 20 min daily, seven days a week. Between T0-T1 the daily training program didn’t change. Results: In the RMT group maximal inspiratory pressure (MIP) significantly increased (T0: 8.9±2.4, T1: 9.4±2.1 kPa; P < 0.05) and an improvement of maximum workload (T0: 389±106 T1: 429±119W.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
