Inspiratory Muscle Training (IMT) in Athletes
Inspiratory Muscle Training (IMT) in Athletes

The purpose of this study is to determine weather well trained athletes benefit from inspiratory (respiratory) muscle training.
  • Subject: The investigators intend to include 40 well trained runners, 18 years or older.
  • Design: Following lung function and exercise testing (incremental treadmill test to exhaustion, 5000m run time trial) participants will be randomly assigned to a verum or a control group. The verum group will train with a hand-held, commercially available pressure threshold loading device (POWERbreathe,UK). The control group will perform a sham-training with the same device. After six to eight weeks the the initial tests will be repeated.
  • Hypothesis: Inspiratory muscle training enhances performance on submaximal work loads and in the 5000m run time trial by changes in breathing pattern. Maximum oxygen uptake remains unchanged.

    Sham training with same handheld device. 50 breaths daily on the lowest level
  • Active Comparator: Training
    respiratory muscle training (pressure threshold loading)
    Intervention: Behavioral: Respiratory muscle training
  • Sham Comparator: sham training
