Summary

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.

  • Muscle Oxygenation
  • Respiratory Function

Interventions

BEHAVIORAL

Core Training Program

A structured, progressive core stability training program targeting trunk and abdominal musculature. The exercises will be conducted 3 days a week for 8 weeks, taking approximately 20-25 minutes before soccer practices.

DEVICE

Inspiratory Muscle Training (IMT)

Inspiratory muscle training performed using a threshold device. The protocol consists of 2 sets of 30 breaths per session, 3 days a week for 8 weeks. Training intensity starts at 50% of maximal inspiratory pressure (MIP) and progresses up to 70% MIP.
