About

This prospective, single-center, interventional pilot (n=23) evaluates the 5-Line Principle of Balanced Intensity Training (BPIT) over 6 weeks at GFFI Fitness Academy. Participants (18 males aged 22-48, 5 females aged 20-33) will receive BPIT 5-Line Training (3 sessions/week, 6 weeks). No control group. Conducted July 1 - November 30, 2024.

Progressive intensity via anatomical lines: 1. Ground-Based (Low Intensity); 2. Knee-Level (Low-Moderate); 3. Standing (Moderate); 4. Head-Level (Moderate-High); 5. Plyometric/High-Impact (High). Aims to assess changes in strength, HRV, and injury risk.

Full description

STUDY DESIGN: Prospective, single-center, interventional pilot (n=23) with single-group assignment. All participants receive the BPIT 5-Line intervention. Assessments at baseline and Week 6.

INTERVENTION: BPIT 5-Line Training: 3 x 60-minute sessions/week for 6 weeks, progressing across five intensity lines: 1. Ground-Based (Low Intensity, e.g., prone planks); 2. Knee-Level (Low-Moderate, e.g., shoulder press); 3. Standing (Moderate, e.g., half-squat); 4. Head-Level (Moderate-High); 5. Plyometric/High-Impact (High Intensity). Specific exercises detailed in Training Protocol Manual.

OBJECTIVES: Primary - Evaluate BPIT's impact on 1RM strength (e.g., squat, bench press, deadlift) and training-related injury incidence. Secondary - Assess changes in HRV (RMSSD), HRR (bpm in 60s), EMG muscle activation, joint biomechanics (knee valgus, spinal curvature), adherence (% sessions completed), and participant feedback (questionnaires).
