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.

Enrollment
36
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.
Traditional resistance training at 70% of one-repetition maximum (1RM) without blood flow restriction.

RECRUITINGPeak 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)
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)
Body Fat Mass
Total body fat mass measured by bioelectrical impedance analysis (InBody). Expressed in kilograms (kg).
Time frame: Baseline (T1), Week 6 (T3)
