简要总结
The aim of this randomized controlled trial study was to assess the effects of an 4-week exercise program on the recovery capacity after a voluntary maximal apnea. Participants will be randomly allocated to perform an experimental breathing protocol (NR-HB), or an usual training using their usual breathing (UB) protocol.
详细描述
It is a multi-center study. 2 different Spanish Freedivers Centres are included in the study (Madrid and Zaragoza).
Divers were randomly assigned to receive an experimental training (NR-HB) or to be included in the Control Group (UB).
The trial included two study visits. Each exercise training program will be applied sessions per week during 4 weeks. Participants received baseline assessments at the beginning of any intervention, and post-intervention assessments at the end of the fourth week.

结局指标
主要结局
Oxygen Saturation change
时间窗: Before and after training intervention (after 4 weeks)
Oxygen Saturation recovery will be record by the experimenters every 5 seconds by a handheld pulse-oximeter during the 1 min recovery time after a maximal dynamic apnea. The outcome was the length of the time to return to 95% SpO2 during the 1 min recovery time after maximal dynamic apnoea
次要结局
- Heart Rate recovery(before and after training intervention (after 4 weeks))
- Lung function (forced spirometry)(before and after training intervention (after 4 weeks))
