简要总结
The purpose of this randomized controlled trial is to investigate the effects of core training and inspiratory muscle training (IMT) on muscle oxygenation and athletic performance in youth male soccer players aged 15-18. A total of 54 healthy soccer players will be included and randomly assigned into three equal groups: the Control Group, the Core Training Group, and the Core Training + IMT Group.
All interventions will be implemented for 8 weeks in addition to routine soccer training sessions. Assessments will be performed at baseline (Week 0), mid-intervention (Week 4), and post-intervention (Week 8). The primary outcome measures of the study are aerobic capacity assessed by the Yo-Yo Intermittent Recovery Test Level 1 and muscle oxygenation parameters monitored via near-infrared spectroscopy (NIRS) using a MOXY monitor. Secondary outcome measures include sprint performance, agility, dynamic balance, core muscle strength and endurance, inspiratory muscle strength, lower extremity explosive power, and soccer-specific technical performance tests.
Overall, this study aims to reveal the combined effects of core training and inspiratory muscle training on muscle oxygenation, respiratory functions, aerobic capacity, and soccer performance, while explaining the underlying physiological mechanisms in youth athletes.
详细描述
Background:
Soccer performance is a multidimensional structure resulting from the interaction of technical, tactical, psychological, and physical components. In modern soccer, players frequently perform high-intensity running, sprinting, directional changes, and repeated efforts. Therefore, aerobic capacity, recovery ability, and the efficiency of muscle oxygen utilization are of critical importance.
Respiratory muscle fatigue during high-intensity exercise can limit performance by triggering the respiratory muscle metaboreflex, which reduces blood flow to peripheral muscles. Inspiratory muscle training (IMT) aims to attenuate these adverse effects by enhancing the strength and endurance of the diaphragm and auxiliary respiratory muscles. Similarly, core training improves trunk stability, enhances movement economy, optimizes force transfer along the kinetic chain, and contributes to athletic performance measures. Near-infrared spectroscopy (NIRS) is a non-invasive technology used to evaluate muscle oxygenation and hemodynamic responses during exercise. The MOXY monitor utilized in this study will allow real-time evaluation of muscle oxygen saturation (SmO2) and total hemoglobin (THb) levels.
Objectives:
The primary objective is to investigate the effects of core training and inspiratory muscle training on muscle oxygenation and aerobic performance in youth male soccer players. Secondary objectives are to examine changes in maximal inspiratory pressure, sprint performance, agility, dynamic balance, core strength/endurance, lower extremity explosive power, and soccer-specific technical skills.
