Body Composition, Muscle Strength, Physical Fitness
Conditions
Brief summary
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.
Interventions
DEVICEKAATSU Master Pneumatic Cuff
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.
BEHAVIORALHigh-Load Resistance Training
Traditional resistance training at 70% of one-repetition maximum (1RM) without blood flow restriction.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peak Force in Isometric Mid-Thigh Pull (IMTP) | 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
| Measure | Time frame | Description |
|---|---|---|
| Countermovement Jump Height (CMJ) | 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). |
| Body Fat Mass | Baseline (T1), Week 6 (T3) | Total body fat mass measured by bioelectrical impedance analysis (InBody). Expressed in kilograms (kg). |
