Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this randomized cross-over controlled 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 receive either a high intensity interval training (HIIT), or an inspiratory muscle training (IMT) using an inspiratory resistance device.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is a multi-center study. 3 different Spanish Freedivers Centres are included in the study (Madrid, Zaragoza, and Barcelona).

For each participant, exercise program started with one or the other program. Hence, both interventions were applied once with the participant randomly allocated to receive the same intervention. The trial included four study visits. Each exercise training program will be applied sessions per week during 4 weeks. Participants received baseline assessments at the beginning of nay intervention, and post-intervention assessments at the end of the fourth week. The wash-out period will be two weeks. After these two weeks participants switched intervention.

High intensity interval training

It will apply a HIIT program for 4 weeks, with 3 sessions per week of 30 min per session, including warm-up, recovery between intervals and return to calm.

Group Type ACTIVE_COMPARATOR

High intensity interval training

Intervention Type OTHER

Participants will perform 3 HIIT sessions per week, involving 10 min of intense exercise within a time commitment of 30 min per session, including warm-up, recovery between intervals and cool down.

Inspiratory muscle training

It will apply an inspiratory muscle training for 4 weeks, with 3 sessions per week of 30 min per session, including warm-up, recovery between intervals and return to calm.

Group Type ACTIVE_COMPARATOR

Inspiratory muscle training

Intervention Type OTHER

Participants will perform 3 inspiratory resistance training sessions per week, involving 30 min per session, including warm-up, recovery between intervals
