This prospective, multi-site, single-arm interventional study evaluates the 5-Line Principle of Balanced Progressive Intensity Training (BPIT) over 5 weeks in healthy adults aged 18-65 years. All participants receive supervised BPIT sessions (3-5 per week) progressing through five intensity lines defined by anatomical landmarks and ground reaction force:
Ground-Based (Low) Knee-Level (Low-Moderate) Standing (Moderate) Head-Level (Moderate-High) Plyometric (High-Impact)
The study aims to quantify improvements in functional movement efficiency, joint mobility, postural control, strength adaptation, and heart-rate variability while monitoring safety and individual overload indicators.
Adults aged 18-65 years Generally healthy with regular physical activity history (at least 1-2 sessions per week for the past 3 months) Able to commit to 3-5 supervised training sessions per week for 5 weeks Willing and able to provide written informed consent Cleared by pre-screening (no acute injury, no contraindications)
Acute musculoskeletal injury within the past 3 months Known cardiovascular, metabolic, or orthopaedic conditions that contraindicate exercise Pregnancy or planning pregnancy Use of medications or supplements that significantly affect muscle recovery or performance (e.g., corticosteroids, anabolic agents) Inability to follow the BPIT protocol or attend required sessions
