Widely used recommendations for determining heart rate maximum (HRmax) in women have been called into question. According to researchers, the popular formula of 220 – Age = HRmax may produce numbers too high for optimal female physical health. After studying how HR response to exercise stress testing was associated with age and death rates among 5,437 asymptomatic women over about 16 years, scientists settled on a new calculation: 206 – (Age x 0.88) = HRmax.
The American Heart Association has recently released an updated guide to CPR. The 2010 American Heart Association Guidelines for CPR and ECC includes the following changes to previous CPR protocol:
Compression rate should be at least 100 compressions per minute, as opposed to “approximately” 100 per minute.
Compression depth should be at least 2 inches in adults, approximately 2 inches in children and 1.5 inches in infants.

The American Heart Association (AHA) recently issued its proactive agenda for the next decade by releasing a strategic plan for measuring, monitoring and improving the cardiovascular health of Americans.
Do you have a client who experiences difficulty executing the sit-and-reach test? If so, inadequate flexibility may not be the only issue plaguing him. A study published in the American Journal of Physiology—Heart and Circulatory Physiology (October 2009; , 1314–18) found that persons over 40 who experience limited trunk flexibility may also suffer from arterial stiffness. The study included 526 nonobese adults aged 20–83 years with no known chronic disease.
Mind-body movement professionals should consider the impact that music can have on their programs. According to a new study published in Circulation (2009; 119 , 3171–80), loud music increases heart rate and blood pressure, while soft music lowers both, independent of subjective musical preferences. This study adds to the growing body
of research documenting the effects of music on mood and physiology.
One day, while I was running on a treadmill at the gym, a personal trainer approached the person next to me to share some advice. “Muriel,” she said, “if you want to burn fat, you should keep your heart rate within a specific zone.” I was so shocked at what I’d heard that I nearly fell off the treadmill!
In 490 BC the ancient Greek hero Pheidippides ran from Marathon to Athens to announce the Greeks’ victory over Persia in the Battle of Marathon. When the modern Olympic Games began in Athens in 1896, a running race named after the Greek town of Marathon was introduced to commemorate Pheidippides’ legendary run. Now there are more than 300 marathons just in the United States each year, with hundreds of thousands of people running them. Chances are that one or two of your clients want to do one. So how do you train them for a marathon?
We’ve known for some time that psychological distress increases the risk of heart attack and other heart
issues. But how does this happen? Is it because people smoke more or don’t exercise enough when they are stressed-out? Or is it because stress can trigger unhealthy physical processes, such as inflammation and hypertension?
People with type 2 diabetes who have higher-than-average blood sugar levels for over 2–3 months also have lower brain function, according to the Memory in Diabetes (MIND) study published in Diabetes Care (2009; 32 ; 221–26). Researchers used data from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial,
a study of 10,251 people with type 2 diabetes and high risk for heart disease. Investigators found
If you have an iPhone, it might be time to give it a healthy upgrade. iTMP Technology Inc., a hardware and software developer for iPhone, has created new technology that allows the iPhone or iPod touch to act as a heart rate and fitness activity monitor. Dubbed SMHEART LINK™, the device acts as a “wireless bridge that collects data from distributed health and fitness sensors such as heart rate monitors and cycling sensors and sends it to the iPhone via Wi-Fi.” Users can then upload collected information onto various health and fitness tracking websites.
