Brief Summary

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.

Conditions

Healthy

Outcome Measures

Primary Outcomes (2)

• Change in 1RM Strength

  Change in one-repetition maximum (1RM) strength for key exercises (e.g., squat, bench press) from baseline to week 6. Measured in kilograms (kg) using standard 1RM testing protocol. Time Frame: Baseline to Week 6 Unit of Measure: kilograms (kg)

  6 weeks

• Injury Incidence

  Number of new musculoskeletal injuries reported during the study period, defined as any complaint requiring medical attention, training modification, or rest exceeding 1 day. Measured as incidence rate per 100 participant-weeks (normalized for exposure in this 23-participant pilot). Unit of Measure: injuries per 100 participant-weeks

  Baseline to Week 6

Secondary Outcomes (6)

• Change in Heart Rate Variability (HRV)

  Week 6

• Change in Muscle Activation (EMG Amplitude)

  Baseline to Week 6

• Change in Joint Biomechanics (Knee Valgus and Spinal Curvature)

  Baseline to Week 6

• Training Adherence

  Baseline to Week 6

• Participant Feedback

  6 weeks

BPIT 5-Line Training

EXPERIMENTAL

All 23 participants (18 males aged 22-48, 5 females aged 20-33) received BPIT 5-Line Training (3-5 sessions/week, 6 weeks). Intensity progressed via 5 Lines: 1. Ground-Based, Low Intensity 2. Knee-Level, Low-Moderate Intensity 3. Standing, Moderate Intensity 4. Head-Level, Moderate-High Intensity 5. Plyometric/High-Impact, High Intensity

Behavioral: BPIT 5-Line Training

Interventions

BPIT 5-Line Training BEHAVIORAL

All 23 participants received BPIT 5-Line Training (3-5 sessions/week, 6 weeks). Intensity progressed via 5 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 Intensity. Sessions 45-60 min, monitored via HRV, pain, fatigue.
