Outline of Final Research Achievements

The purpose of the present study was to clarity the effect of respiratory muscle endurance training in hypoxia on respiratory muscle-induce metaboreflex. Collegiate male endurance runners assigned to a normoxic or hypoxic group. Before and after 6 weeks of respiratory muscle endurance training, cardiovascular response to an incremental respiratory endurance test was measured. Minute ventilation during the training increased progressively. Target SpO2 in the hypoxic group set at 80%. The change arterial blood pressure during the incremental respiratory endurance test reduced significantly after the training in both groups. No significant difference in arterial blood pressure during hyperpnoea was found after the training between the two groups. These results suggest respiratory muscle-induced metaboreflex is attenuate by respiratory muscle endurance training, but no additional effect appears when the training is performed under hypoxic conditions.
