About this study
This research aims to explore the impact of two distinct methods of respiratory muscle training, voluntary isocapnic hyperpnoea (VIH) and inspiratory pressure threshold loading (IPTL), on athletic performance and pulmonary function in short-track speedkaters. The study will employ a parallel group-randomized trial design and will span a period of six weeks, during which participants will undergo regular, partially supervised training sessions.
The primary objective of the research is to assess the changes in athletic performance resulting from respiratory muscle training using VIH and IPTL techniques. Athletic performance will be measured through a range of standardized performance tests relevant to the participants' specific sporting activities (Wingate Test, CPET, on-ice time-trial performance). Pulmonary function will be measured by spirometry examination.
The group will consist of healthy, highly-trained professional short-track speedskaters.
Read the detailed description
This study aims to investigate the effects of two different respiratory muscle training methods, namely voluntary isocapnic hyperpnoea (VIH) and inspiratory pressure threshold loading (IPTL), on athletic performance and pulmonary function. The research will adopt a parallel group-randomized trial design, spanning a six-week period of regular, partially supervised training sessions.
The primary objective is to evaluate changes in athletic performance resulting from respiratory muscle training using VIH and IPTL techniques. Standardized performance tests relevant to the participants' specific sports will be utilized (Wingate Test, CPET, on-ice time-trial performance).
In addition, the impact of respiratory muscle training on pulmonary function will be assessed, focusing on parameters such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF). These measurements will provide insights into the potential enhancements of respiratory muscle strength and function through VIH and IPTL.
Participants will be randomly assigned to either the VIH or IPTL training group. Regular training sessions will be conducted under partial supervision to ensure proper technique and adherence. Close monitoring will be implemented to track progress and identify any potential adverse effects.
The findings of this research will hold implications for athletes and individuals seeking to optimize their athletic performance and respiratory muscle function. By comparing the effects of VIH and IPTL, the study aims to identify the most effective respiratory muscle training method.
Ultimately, this research will contribute to the existing knowledge on respiratory muscle training and its potential benefits for athletes and individuals engaged in physical activities. The results obtained will provide evidence-based guidance for the development of targeted training protocols that can enhance athletic performance and respiratory health.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Respiratory Muscle Training - VIHBehavioural
The VIH group will train every second day with gradual progression based on session length and breathing frequency. Participants will begin with 3 minutes of exercise with a frequency of 20 breaths·min-1 during the first session and add no more than 1 minute or 2 breaths·min-1 with each consecutive session.
Respiratory Muscle Training - ITPLBehavioural
The IPTL group will train 5 days a week, twice a day, with at least 6 hours break between sessions. The session will consist of 30 dynamic inspiratory maneuvers with progressive overload based on gradually increased resistance. The VIH group will train every second day with gradual progression based on session length and breathing frequency. Participants will begin with 3 minutes of exercise with a frequency of 20 breaths·min-1 during the first session and add no more than 1 minute or 2 breaths·min-1 with each consecutive session.
