The Effects of the New KAATSU-Cycle Blood Flow Restriction Protocol on Metabolism, and Perceptual, Mood and Cognitive

SUMMARY: The study concludes that the KAATSU-Cycle protocol (intermittent blood flow restriction) evokes a metabolic stimulus similar to continuous KAATSU training but with significantly lower ratings of perceived exertion and physical pain, making it a more tolerable exercise modality.

Effects of Blood Flow Restriction Training on Physical Fitness Among Athletes

SUMMARY: The study concludes that blood flow restriction training (BFRT) is a safe and scientifically effective method that significantly improves an athlete's strength, power, speed, endurance, and muscle mass, especially when performed at least three times per week with cuff pressures of 160 mmHg or higher.

Effects of Blood Flow Restriction via KAATSU AQUA on Speed and Endurance in Young Water Polo Players

SUMMARY: This study concludes that incorporating KAATSU AQUA (blood flow restriction) into the training of young water polo players significantly improves swimming speed, high-intensity exercise endurance, and performance under lactic acid accumulation compared to traditional training alone.

Effects of KAATSU on Muscular Function During Isometric Exercise

SUMMARY: This study concludes that performing low-intensity (20% MVC) intermittent isometric exercise with or without KAATSU vascular restriction does not produce significant neuromuscular fatigue or changes in voluntary muscle activation, suggesting that higher intensities or pressures may be required to elicit these specific effects during isometric tasks.

Effects of Low-Intensity Bench Press Training with Restricted Arm Muscle Blood Flow on Chest Muscle Hypertrophy - A Pilot Study

SUMMARY: This study concludes that just two weeks of low-intensity bench press training combined with KAATSU (blood flow restriction) on the arms significantly increases the size of both the restricted upper-arm muscles and the non-restricted chest muscles, as well as overall bench press strength.

Effects of Piano Performance with KAATSU Twice Daily for 3 Weeks on Neuromuscular Mechanisms - A Case Study

SUMMARY: This case study concludes that three weeks of twice-daily piano performance combined with KAATSU training effectively induces upper-limb muscle hypertrophy and increases arm girth, suggesting its potential for enhancing the physical capabilities of musicians, though it did not result in immediate improvements in maximal strength or rate of force development.

Effects of Resistance Exercise Combined with Vascular Occlusion on Muscle Function in Athletes

SUMMARY: This study concludes that low-intensity resistance exercise combined with KAATSU (vascular occlusion) induces significant increases in muscle size, strength, and dynamic endurance even in elite, highly trained athletes, proving it to be a potent training stimulus for individuals who typically require high-intensity loads for adaptation.

Eight Days KAATSU-Resistance Training Improved Sprint but not Jump Performance in Collegiate Male Track and Field Athletes

SUMMARY: Eight days of twice-daily, low-intensity KAATSU resistance training significantly increased muscle size and leg strength in elite collegiate athletes, directly leading to improved 30-meter sprint acceleration while maintaining jump performance.

Fatigue Characteristics During Maximal Concentric Leg Extension Exercise with Blood Flow Restriction

SUMMARY: The study concludes that while very short rest intervals (less than 1.5 seconds) induce high muscle fatigue regardless of blood flow, KAATSU (blood flow restriction) is uniquely effective at significantly increasing fatigue during exercises with longer rest intervals (3.5 seconds), thereby potentially enhancing the anabolic training stimulus.

The Effects of Blood Flow Restriction Training on VO2 Max and 1.5 Mile Run Performance

SUMMARY: This study concluded that three weeks of low-intensity blood flow restriction walk training is an effective methodology for simultaneously improving aerobic capacity (VO2max), running endurance, and muscle size in well-trained males.

The Effects of Moderate Blood Flow Restriction Induced by KAATSU on Muscle Activation, Heart Rate, and Rate of Perceived Exertion During Low-Intensity Aerobic Exercise - A Pilot Study

SUMMARY: This pilot study concludes that utilizing KAATSU during low-intensity cycling allows a user to reach their anaerobic threshold with significantly reduced heart rate, mechanical load, and perceived exertion while maintaining muscle activation levels comparable to high-intensity exercise without restriction.

The Potential of Blood Flow Restriction Exercise to Overcome Jetlag - Important Implications for Tokyo 2020

SUMMARY: This editorial proposes that KAATSU (Blood Flow Restriction) exercise serves as a safe, effective countermeasure against jet lag by accelerating the resynchronization of circadian rhythms through specific physiological adaptations—such as mTOR pathway stimulation—thereby allowing athletes to maintain performance despite rapid time zone changes.
