Active Voice: KAATSU Training An Emerging Research Area & New ACSM Interest Group
By Alan Mikesky, Ph.D., FACSM and Michael Bemben, Ph.D., FACSM Share
Alan Mikesky, Ph.D., FACSM is professor and director of the Human Performance & Biomechanics Laboratory in the Department of Physical Education at Indiana University-Purdue University Indianapolis. His research interests in applying resistance training to various clinical populations led him to Japan, where he was taught by the founder of KAATSU training. Michael Bemben, Ph.D., FACSM is C.B. Hudson Presidential Professor in the Department of Health & Exercise Science at the University of Oklahoma in Norman. His research area is neuromuscular function in aging, with particular emphasis on exercise training, adaptive mechanisms and outcomes relative to muscle mass, strength and balance. Drs. Mikesky and Bemben co-chair the ACSM KAATSU special interest group, and they have conducted funded research and published articles regarding the physiologic and performance effects of KAATSU training.
In the last decade, there has been a large increase in the number of conference presentations and peer-reviewed publications reporting the effects of combining resistance training with muscle blood flow restriction. Many of the studies have been conducted in Japan where this type of training is known as “KAATSU” (the Japanese word for pressure). KAATSU is the addition of pressure via pneumatic limb cuffs that restrict, not occlude, blood flow to the exercising muscles. Because of the growing interest and potential applications of KAATSU, we want to introduce it by addressing several commonly asked questions.
What’s different about KAATSU?
Besides wearing the pneumatic cuffs that restrict blood flow while exercising, KAATSU training is different than traditional resistance training, as more repetitions are performed with lighter resistances. Typical resistance training involves performing 1-3 sets of 8-10 repetitions with loads that exceed 60 percent of maximal muscle strength. KAATSU involves three sets of 15 or more repetitions using loads that range from 10-50 percent of maximal strength. It is the lighter loads that make KAATSU a potentially viable option for certain clinical applications. More
Policy Corner: Addressing Physical Activity and Health Disparities
This month, ACSM’s Sports Medicine Bulletin (SMB) is featuring a special series in observance of February as Black History Month. This series is covering a broad spectrum of diversity-related issues that pertain to our members, the world’s leading sports medicine and exercise science professionals. This week, ACSM focuses on the way recent policy initiatives are addressing health disparities among diverse populations.
Research—augmented by abundant empirical evidence—has shown that higher levels of physical activity are associated with better health. This is true for people of all ages, any level of ability, and every ethnicity. Factors that inhibit participation in physical activity, sports and exercise, therefore, contribute to less desirable health outcomes. The nexus of physical activity and health disparities provides a window on some alarming realities and suggests strategies for addressing them. More
CEPA Releases Salary Survey Results
The Clinical Exercise Physiology Association (CEPA), an affiliate society of ACSM, recently released results from their 2010 Clinical Exercise Physiology Practice Survey. More than 800 people participated in the online survey. The median age was 36-40 years, and 68 percent of respondents were women. Ninety-four percent worked in the U.S., and four percent worked in Canada. The majority of respondents (82 percent) worked primarily with patients with cardiovascular disease. In addition, 749 (92 percent) clinical exercise professionals reported having a bachelor’s degree or higher and did not report a concomitant degree or certification for another profession (dietitian, nurse, etc.).
Among the 749 clinical exercise professionals:
SHI Youth Committee Launches REACH Website
Yesterday, the ACSM Strategic Health Initiative on Youth Sports and Health committee launched a new website to provide adults with a robust, searchable database of reliable information on youth sports and health.
The ACSM REACH website will help parents, coaches, health care providers, educators and others find credible, expert-reviewed information on youth sports and health. Experts on the committee review and approve all material included in the database, ensuring that all content on the site is medically accurate and provides sound advice. Visitors can search the database either by sports-related keyword, such as “baseball” or “injury,” or by their relationship to the youth athlete, such as “parent” or “coach.”
The site is a product of ACSM’s Active NationTM initiative, which promotes youth health and fitness and combats childhood overweight and obesity through research, education and initiatives.

Ice Age: The Science Behind Cold Water Immersion
Swimming World Share
In the midst of record-setting winter storms and rapidly-falling temperatures, hot showers and warm fireplaces seem like a perfect remedy for just about any ailment. The last thing anyone wants to do is jump into a bucket of ice-cold water.
But across the country, swimmers lower themselves into freezing training room tubs and make trips to hotel ice machines so they can hopefully reverse some of the muscle damage they've amassed from the week's hard workouts or a couple of sessions at a championship meet. More
1-Minute Sideline Test Predicts Concussions
Should Green Bay Packers quarterback Aaron Rodgers have stayed in a crucial playoff game after taking a violent blow to the head?
A Super Bowl berth was the ultimate outcome. But had Rodgers taken a new one-minute concussion test on the sidelines, his coaches would have known whether he was at risk of a far worse outcome: serious brain damage. More
