简要总结
This study aims to investigate the relationships among pulmonary function, aerobic performance, anaerobic performance, and isokinetic trunk muscle performance in professional male wrestlers. Wrestling requires a combination of high muscular strength, repeated high-intensity efforts, aerobic capacity, anaerobic performance, and effective trunk muscle function. However, the relationships among these physiological and muscular performance characteristics have not been fully established in professional wrestlers.
This single-center, analytical, cross-sectional observational study will include approximately 28 professional male wrestlers aged 18-35 years who have been actively participating in licensed wrestling for at least 5 years and who meet the predefined eligibility criteria. Participants will undergo anthropometric assessment, pulmonary function testing by spirometry, cardiopulmonary exercise testing with respiratory gas analysis, Wingate anaerobic testing, and isokinetic assessment of trunk muscle performance.
Pulmonary function parameters will be obtained from spirometry. Aerobic capacity will be evaluated using maximal oxygen consumption (VO₂max) obtained during cardiopulmonary exercise testing. Anaerobic performance will be assessed using the Wingate test, while trunk flexor and extensor muscle performance will be evaluated using isokinetic dynamometry. The study will primarily examine the relationship between pulmonary function parameters and isokinetic trunk muscle performance. Secondary analyses will evaluate the relationships of pulmonary function and trunk muscle performance with VO₂max and Wingate-derived anaerobic performance parameters.
详细描述
Wrestling is a physically demanding combat sport that requires athletes to perform repeated high-intensity efforts while maintaining strength, power, postural control, and technical performance. The physiological demands of wrestling involve multiple interacting components, including pulmonary function, aerobic capacity, anaerobic performance, and trunk muscle strength and endurance. Trunk musculature plays an important role in maintaining body position, transferring force between the upper and lower extremities, and performing wrestling-specific movements. Pulmonary and cardiovascular capacity may also contribute to the ability to sustain repeated efforts and recover between high-intensity bouts. Despite the importance of these components, the relationships among pulmonary function, aerobic and anaerobic performance, and isokinetic trunk muscle performance in professional wrestlers have not been fully characterized.
The primary aim of this study is to investigate the relationship between pulmonary function parameters and isokinetic trunk muscle performance in professional male wrestlers. Specifically, the study will examine the associations between pulmonary function parameters obtained from spirometry and the performance of the trunk flexor and extensor muscles assessed using isokinetic dynamometry.
The secondary aim is to evaluate the relationships of pulmonary function parameters and isokinetic trunk muscle performance with aerobic and anaerobic performance. Aerobic capacity will be represented by maximal oxygen consumption (VO₂max) obtained during cardiopulmonary exercise testing with respiratory gas analysis. Anaerobic performance will be evaluated using the Wingate test and its relevant performance parameters. In this way, the study aims to provide a comprehensive assessment of the relationships among pulmonary function, aerobic capacity, anaerobic performance, and trunk muscle performance in professional wrestlers.
This is a single-center, analytical, cross-sectional observational study. The study population will consist of professional male wrestlers evaluated at the Department of Sports Medicine, Istanbul Faculty of Medicine, Istanbul University. Approximately 28 professional male wrestlers who meet the eligibility criteria will be included. Eligible participants will be between 18 and 35 years of age, will have been actively participating in licensed wrestling for at least 5 years, and will be actively competing at the professional level while maintaining a regular training program. Participants will be evaluated after providing written informed consent.
No therapeutic intervention or exercise training program will be administered as part of the study. Each participant will undergo anthropometric assessment and a series of physiological and muscular performance evaluations. Participant characteristics, including age, height, body weight, body mass index, wrestling style, weight category, years of licensed wrestling participation, duration of professional athletic participation, weekly training frequency and duration, smoking status, known medical conditions, regular medication use, previous surgical procedures, and recent musculoskeletal injuries will be recorded.

结局指标
主要结局
Forced Vital Capacity (FVC)
时间窗: Baseline
Forced vital capacity (FVC) is the maximum volume of air that can be forcibly exhaled after a maximal inspiration. It will be assessed by spirometry and reported in liters (L), with values approximately 80-120% of the predicted value considered within the normal range.
Forced Expiratory Volume in 1 Second (FEV₁)
时间窗: Baseline
Forced expiratory volume in 1 second (FEV₁) is the volume of air that can be forcibly exhaled during the first second following maximal inspiration. It will be assessed by spirometry and reported in liters (L), with values approximately 80-120% of the predicted value considered within the normal range.
FEV₁/FVC Ratio
时间窗: Baseline
The FEV₁/FVC ratio represents the proportion of the forced vital capacity exhaled during the first second of forced expiration. It will be assessed by spirometry and reported as a percentage (%), with values ≥70% generally considered within the normal range in adults.
Peak Expiratory Flow (PEF)
时间窗: Baseline
Peak expiratory flow (PEF) is the maximum flow rate achieved during a forced expiration following maximal inspiration. It will be assessed by spirometry and reported in liters per second (L/s), with values interpreted according to age, sex, height, and predicted reference values.
Maximum Voluntary Ventilation (MVV)
时间窗: Baseline
Maximum voluntary ventilation (MVV) is the maximum volume of air that can be inhaled and exhaled voluntarily over a specified period of time.
