These demands may be related not only to strength and conditioning, but also to the coordination between breathing and postural control. The diaphragm is the main muscle for breathing and also contributes to trunk stability through its role in pressure regulation and deep core control. However, dysfunctional breathing patterns, such as upper-chest dominant breathing, reduced lower rib expansion, or poor coordination between the chest and abdomen, may interfere with this function.\n\nThe purpose of this study is to examine dysfunctional breathing patterns in combat sport athletes and to investigate whether diaphragmatic breathing retraining can improve breathing patterns, diaphragm function, core stability, postural control, and sport-related performance. This study will first screen athletes from combat and non-combat sports to determine the prevalence of dysfunctional breathing. Combat sport athletes will then complete laboratory tests to examine the relationship between breathing pattern, posture, diaphragm function, core stability, and postural control. In the intervention part of the study, combat sport athletes with dysfunctional breathing will be randomly assigned to diaphragmatic breathing retraining plus usual training or usual training only. The study will compare the two groups to determine whether adding diaphragmatic breathing retraining provides additional benefits. The study will also examine whether the changes are maintained after training and whether baseline measures can help identify athletes who respond better to the program.",[27,28,29],"Respiratory Muscle Function","Athletic Performance","Postural Balance",[31,32,33,34,35,36],"Combat sport athletes","Dysfunctional breathing","Diaphragmatic function","Diaphragmatic breathing retraining","Core stability","Postural control","RECRUITING","2026-07-15",{"date":40,"type":41},"2026-07-21","ACTUAL",{"date":43,"type":41},"2026-05-01",{"date":45,"type":21},"2029-07",{"name":47,"class":48},"National Cheng Kung University","OTHER",1,{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":4,"eligibilityCriteria":56,"healthyVolunteers":57,"sex":16,"minAge":58,"maxAge":59,"enrollmentInfo":60,"targetDuration":4,"studyType":22,"phases":62,"briefSummary":63,"conditions":64,"keywords":67,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":70,"lastUpdatePostDateStruct":71,"startDateStruct":73,"completionDateStruct":75,"leadSponsor":77,"locationsCount":49},"100629995","inspiratory-muscle-warm-up-in-combat-athletes-100629995","NCT07481916","Inspiratory Muscle Warm-Up in Combat Athletes","The Effect of Respiratory Muscle Warm-Up on Technical and Physiological Responses in Combat Athletes","Inclusion Criteria:\n\n* Male and female combat athletes aged 15 to 22 years\n* Registered with the Turkish Kickboxing and Muay Thai Federation\n* Regularly engaged in training\n* At least 2 years of licensed sports experience\n* Having won medals at the national or international level\n\nExclusion Criteria:\n\n* Presence of respiratory disease\n* Presence of cardiopulmonary disease",true,"15 Years","22 Years",{"count":61,"type":21},20,[24],"The aim of this study is to investigate the effects of inspiratory muscle warm-up (IMW) on technical performance and physiological responses in combat athletes. A total of 20 volunteer athletes (10 males, 10 females), aged 15-22 years, registered with the Turkish Kickboxing and Muay Thai Federation, with at least two years of licensed sports experience and medal achievements at the national or international level, will be included in the study. The study will be conducted using a placebo-controlled, randomized, double-blind, crossover experimental design, in which participants will complete the control (general warm-up), placebo (15% MIP), and IMW (40% MIP) conditions in a random order.\n\nIn each session, before and after the warm-up, pulmonary function tests (FVC, FEV1, FEV1\u002FFVC, PEF), respiratory muscle strength (MIP, MEP), heart rate, perceived exertion, and dyspnea levels will be assessed. In addition, athletes will perform the Kickboxing Fitness Test (KFT), and the same measurements will be repeated during the rest intervals of the test and immediately after its completion. The IMW protocol will be performed using a POWERbreathe device at 40% of MIP, consisting of 2 sets of 30 breaths. Furthermore, maximal oxygen uptake (VO₂max) tests will be conducted to evaluate the athletes' general physiological capacity. This study is expected to provide original data for the field of sports sciences by demonstrating the potential contributions of inspiratory muscle warm-up to the improvement of technical skills and physiological capacity in combat athletes, and to generate practical scientific recommendations for coaches and athletes.",[65,27,66],"Sports Performance","Cardiorespiratory Responses",[68,69],"Inspiratory muscle warm-up","combat athletes","2026-03-18",{"date":72,"type":41},"2026-03-23",{"date":74,"type":41},"2026-01-01",{"date":76,"type":21},"2026-06-01",{"name":78,"class":48},"Ondokuz Mayıs University"]
