INTRODUCTION
Respiratory muscles strength and endurance influence athletic performance. Besides conventional spirometry, sniff test, inspiratory and expiratory maximal pressures can directly assess respiratory muscle strength. Respiratory muscles can be train through a device offering inspiratory and expiratory resistance.
METHODS
Nineteen subjects aged 18 to 30 years and practicing leisure sport trained inspiratory muscles on Powerbreathe(®) for eight weeks. Resistance was set at 85% of maximal inspiratory pressure determined during a preliminary session. Evaluation was made trough voluntary and non-invasive methods on Macro 5000(®) (PI max, PE max and sniff test).
RESULTS
An increase of 21.77% of the maximum inspiratory pressure, 17% of the maximum expiratory pressure and 18% of the sniff test are recorded after eight weeks of training.
CONCLUSIONS
A specific training of inspiratory muscles (Powerbreathe(®) Sports performance) increases the power of these muscles (voluntary and non-invasive tests).
引言
呼吸肌力量和耐力会影响运动表现。除了传统肺活量测定法外，嗅气试验、吸气和呼气最大压力可直接评估呼吸肌力量。呼吸肌可通过提供吸气和呼气阻力的设备进行训练。
方法
19名年龄在18至30岁之间且进行休闲运动的受试者在Powerbreathe（®）上进行吸气肌训练，为期八周。阻力设置为在初步测试期间确定的最大吸气压力的85%。通过Macro 5000（®）上的自主和非侵入性方法进行评估（最大吸气压力、最大呼气压力和嗅气试验）。
结果
经过八周训练后，最大吸气压力增加了21.77%，最大呼气压力增加了17%，嗅气试验增加了18%。
结论
吸气肌的特定训练（Powerbreathe（®）运动表现）可增强这些肌肉的力量（自主和非侵入性测试）。
