Brief Summary

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.

Study Arms (2)

Voluntary Isocapnic Hyperpnoea (VIH)

ACTIVE COMPARATOR

Group performing respiratory muscle training with Voluntary Isocapnic Hyperpnoea (VIH) method.

Behavioral: Respiratory Muscle Training - VIH

Inspiratory Pressure Threshold Loading (IPTL)

ACTIVE COMPARATOR

Group performing respiratory muscle training with Inspiratory Pressure Threshold Loading (IPTL) method.

Behavioral: Respiratory Muscle Training - ITPL

Interventions

Respiratory Muscle Training - VIH BEHAVIORAL

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.

Voluntary Isocapnic Hyperpnoea (VIH)

Respiratory Muscle Training - ITPL BEHAVIORAL

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.
