• Both magnetic field mitochondrial regulation and low-load blood flow restriction significantly enhance lower limb muscle strength, explosive power, and strength endurance after 4 weeks of intervention.
• Low-load blood flow restriction is more effective for maximal strength gains, including distal muscle groups, whereas magnetic stimulation improves maximal strength without fatigue accumulation.
• Magnetic stimulation excels in single-joint explosive power, while blood flow restriction is superior for multi-joint explosive power; both are equally effective overall.
• Combined application of magnetic stimulation and low-load blood flow restriction produces synergistic effects, offering a promising training approach for rehabilitation and sports injury patients.
