About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

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

Disqualifiers

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

Trial design

Design model

Parallel

Treatments tested in this trial

  • 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.

Treatment groups

36 Participants
are divided into 2 treatment groups
Group A: Low-Load Blood Flow Restistance Training (LL-BFR)Experimental treatment 1 intervention
Group B: Traditional High-Load Resistance Training (HL-RT)Active comparator 1 intervention

Trial outcomes

Primary outcomes

1

Peak Force in Isometric Mid-Thigh Pull (IMTP)

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).

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

Secondary outcomes

1

Countermovement Jump Height (CMJ)

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).

Time frame
Baseline (T1), Week 6 (T3)
2

Body Fat Mass

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

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