If you follow KAATSU protocols, there are very few risks to using KAATSU for the vast majority of people. There are risks for any kind of exercise, so we always recommend checking with your physician before starting any new fitness or exercise program.
KAATSU has been used for decades by people with a very wide range of physical abilities, disabilities, and medical conditions. There is no other BFR company in the market with as long a safety record as KAATSU. When you choose KAATSU as a BFR training system, you are choosing what is arguably the safest system available.
The contraindications to KAATSU use are largely the same as the contraindications to exercise as recommended by the American Heart Association. These are:
- Acute myocardial infarction (MI / “heart attack”), within 2 days
- Ongoing unstable angina
- Uncontrolled cardiac arrhythmia with hemodynamic compromise
- Active endocarditis
- Symptomatic severe aortic stenosis
- Decompensated heart failure
- Acute pulmonary embolism, pulmonary infarction, or deep vein thrombosis
- Acute myocarditis or pericarditis
- Acute aortic dissection
- Physical disability that precludes safe and adequate exercise
In addition, to be safe, people with an acute infection, unclear tumour status, acute vena cava dissociation, macular degeneration, chronic lymphedema, pregnancy, or severe hypertension (Systolic >180 or Diastolic >110) should also avoid using KAATSU. We also recommend that children under age 14 do not use KAATSU.
When you consider all that’s gone into the development of KAATSU, it’s clear that it was designed with safety in mind. KAATSU has a long history of being used with very few complications, and it has a clear set of guidelines outlining how to use it properly. It is quite likely the safest product in the blood flow restriction training market.
I hope this answers the question of what are the risks of using KAATSU. If you would like more clarification, please read through the other FAQs about KAATSU, or leave a question in the comment box below.
