Jason Karp’s article, “The Fat-Burning Zone” [October 2009 IDEA Fitness Journal], was very informative as to the mechanisms by which fat is oxidized. I agree that high-intensity interval training is an excellent way to burn more calories and increase cardiovascular fitness. However, I take exception to his specific workout recommendations that we should have our clients doing 5–6 reps of 3-minute intervals at 95%–100% max HR or 4 reps of 4-minute intervals at 95%–100% max HR.
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!
When you’re a sports fan, it doesn’t matter if you prefer the NBA, figure skating or the Olympics—you’re sure to admire the performances of athletes who work inconceivably hard to achieve greatness. It’s practically impossible to watch without feeling compelled to hit the gym and try some new training method, hoping to achieve your own gold-medal performance. So what’s the latest buzz in the training room?
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?
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
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?
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.
