<![CDATA[General Background: Enhancing endurance and physiological efficiency is crucial for optimizing young football players' performance. Specific Background: Variable intensity training is widely recognized for improving endurance, while magnetized water has been explored for its potential physiological benefits. However, its combined effects on endurance and physiological indicators in young athletes remain underexplored. Knowledge Gap: Limited research has examined the integration of variable intensity training with magnetized water consumption in the context of football endurance. Aims: This study investigates the impact of variable intensity training and magnetized water consumption on special endurance and key physiological indicators in young footballers. Results: After a 16-week experimental intervention with 12 athletes from Al-Zawraa Sports Club, significant improvements were observed in strength endurance, speed endurance, hemoglobin levels, and blood viscosity. Magnetized water facilitated hydration, reduced fatigue, and enhanced oxygen transport, contributing to overall endurance development. Novelty: This study is among the first to demonstrate the synergistic effects of magnetized water and variable intensity training on young footballers’ endurance and physiological adaptation. Implications: These findings suggest that structured fluid intake strategies incorporating magnetized water can optimize endurance training outcomes, offering valuable insights for coaches and sports scientists in developing evidence-based hydration and training protocols. Highlights: Boosts Endurance: Enhances strength and speed endurance in young footballers. Improves Hydration: Magnetized water aids oxygen transport and reduces fatigue. Optimizes Training: Supports evidence-based hydration and endurance strategies. Keywords: Variable intensity training, magnetized water, endurance, physiological adaptation, young footballers]]>
