BPIT 5-Week Multi-Site Study: Movement Efficiency, Mobility & Neuromuscular Adaptation

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.
