Is this trial a fit for you?
✓Likely a good fit
Competitive kickboxing or Muay Thai athletes aged 15–22 registered with the Turkish Kickboxing and Muay Thai Federation, with at least two years of licensed experience and national or international medals, without respiratory or cardiopulmonary disease.
✕Probably not a fit
Athletes outside the 15–22 age range, non-combat or recreational athletes, or anyone with existing respiratory or cardiopulmonary disease are unlikely to benefit from the results.

What this trial studies
This randomized, double-blind, placebo-controlled crossover trial will enroll 20 competitive kickboxing and Muay Thai athletes (10 male, 10 female) aged 15–22 to compare three conditions: general warm-up (control), a low-intensity placebo (15% MIP), and an inspiratory muscle warm-up (40% MIP). Participants complete each condition in random order and perform the Kickboxing Fitness Test (KFT) with pre- and post-measurements. Measurements include pulmonary function (FVC, FEV1, FEV1/FVC, PEF), respiratory muscle strength (MIP, MEP), heart rate, perceived exertion, and dyspnea. Sessions take place at Ondokuz Mayıs University using a POWERbreathe device.
Why it matters
Potential benefit: If successful, this warm-up could yield small but practical improvements in breathing comfort and technical performance during training and competition.
How similar studies have gone: Previous small trials in cycling, running, and team sports have reported modest breathing and performance gains from inspiratory muscle warm-ups, but evidence specifically in combat sports is limited.
