Effects of Blood Flow Restriction Training on Body Composition and Maximal Strength in Military Personnel

This study aims to compare the effects of low-intensity blood flow restriction training combined with resistance training versus traditional high-intensity resistance training on body composition (skeletal muscle mass, body fat mass) and maximal strength (isometric mid-thigh pull, vertical jump, isometric squat pull) in male military academy cadets. The study lasts for 6 weeks and adopts a randomized parallel-group design.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male cadets from military academy;
  • No contraindications to blood flow restriction training (no circulatory diseases, skin allergies);
  • Healthy and capable of high-intensity exercise;
  • Signed informed consent

Exclusion criteria

  • Major sports injury within 2 years (fracture, ligament tear, muscle/tendon rupture, habitual joint dislocation);
  • Cardiovascular or visceral organ diseases;
  • Other conditions unsuitable for training

Treatment and study plan

KAATSU Master Pneumatic Cuff

Device

Pneumatic pressure cuffs applied to the proximal thigh at 200 mmHg to achieve partial blood flow restriction during low-load resistance training (30% 1RM). Initial warm-up at 40 mmHg.

High-Load Resistance Training

Behavioral

Traditional resistance training at 70% of one-repetition maximum (1RM) without blood flow restriction.

Primary outcomes

  1. Peak Force in Isometric Mid-Thigh Pull (IMTP)

    Time frame: Baseline (T1), Week 3 (T2), Week 6 (T3)

    Maximal vertical ground reaction force during isometric mid-thigh pull measured on ELIGA portable force plate. Participants pull a fixed bar with knee angle 125°-135° for 3-5 seconds. Best of 2 trials recorded in Newtons (N).

Secondary outcomes

  1. Countermovement Jump Height (CMJ)

    Time frame: Baseline (T1), Week 6 (T3)

    Vertical jump height calculated from flight time measured on ELIGA portable force plate. Formula: height = g × t²/8, where g = 9.81 m/s². Hands on hips, self-selected countermovement depth. Best of 3 trials in centimeters (cm).

  2. Body Fat Mass

    Time frame: Baseline (T1), Week 6 (T3)

    Total body fat mass measured by bioelectrical impedance analysis (InBody). Expressed in kilograms (kg).
