Research and Practice in Conditioning
1. Assessment: Establishment of a multidimensional fatigue assessment system utilizing salivary human herpesviruses and related biomarkers.
2. Intervention: Elucidation of recovery mechanisms underlying (A) acupuncture and physical therapy, and (B) thermal and cryotherapy.
3. Education: Development of a professional training program to empower acupuncture and physical therapists with visual impairment as sports trainers.
4. Implementation: Practical application of conditioning support, targeting primarily para-athletes.
