Influence of Respiratory Muscle Training on Objective & Subjective

Status Completed

Clinical Trial Summary

Two groups of healthy, highly trained triathletes trained respiratory muscles with one of the two methods: voluntary isocapnic hyperpnoea (VIH) or inspiratory pressure threshold loading (IPTL). The main purpose of this study was to accurately and thoroughly assess the potential extra load that RMT puts on athletes and determine if there are significant differences in RMT-induced load between the investigated training methods. Informed written consent was obtained from the all study participants. All procedures were carried out in accordance with the Declaration of Helsinki.

Clinical Trial Description

The study was conducted as a randomized controlled trial with two parallel groups. Whereas participants and data collectors were aware of the allocated training method, the data analysts and laboratory technicians performing biochemistry assays were kept blinded to the allocation. The participants were assigned at random to either VIH or IPTL training group to perform RMT with progressive overload for 6 weeks. Three training sessions (week 1, 4, 6) were monitor to assess the potential extra load that RMT puts on athletes and determine if there are significant differences in RMT-induced load between the investigated training methods. Blood samples used for acid-base balance (pH), partial pressure of oxygen (pO2), partial pressure for carbon dioxide (pCO2), partial pressure for bicarbonate ion (HCO3-), and blood lactate (bLa) were collected immediately after cessation of the exercise and MPQ was presented 1' after cessation of the exercise. Blood samples for cortisol (C) and testosterone (T) were collected 5' after cessation of the exercise. The second S-Index Test was performed between minute 5 and minute 7 after cessation of the exercise. RPE was assessed 10' after cessation of the exercise. The participants again answered MPQ after 24h and 48h after the monitored RMT sessions. Informed written consent was obtained from the all study participants. All procedures were carried out in accordance with the Declaration of Helsinki. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
