Nitrate supplementation has become increasingly popular in recent years among athletes and fitness enthusiasts alike. Its popularity is not without merit as previous research (using beetroot) has shown that athletes can benefit from a reduction in the oxygen cost of submaximal exercise; thereby increasing overall endurance and tolerance to high-intensity work. A new study published in the March 2015 issue of the Federation of American Societies for Experimental Biology journal helps shed new light on how some nitrate supplements may work, and why they potentially increase performance. The team found that they essentially decrease the viscosity of circulating blood, aiding in blood flow, while simultaneously ensuring tissue oxygen requirements are not compromised. "Our research sheds new light on how oxygen delivery to bodily tissues is controlled to support mammalian life, and what role the kidneys and the liver play in achieving this," said Andrew Murray, Ph.D., a researcher from the Department of Physiology, Development and Neuroscience at the University of Cambridge, United Kingdom.
About 70 million American have hypertension – roughly 29% of the country’s population. Furthermore, nearly 1 in 3 adults are prehypertensive. In total, the annual cost of high blood pressure is $46 billion dollars. Excessive sodium intake correlates positively with high blood pressure, and a recent report by the Center for Disease Control (CDC) found that more than 70% of pizzas, pasta mixed dishes and meat mixed dishes, and 50% to 70% of cold cuts, soups and sandwiches exceeded recommended sodium levels per serving set forth by the FDA.
NCSF Board for Certification has received re-accreditation through 2020. The NCCA reviews certification programs annually to ensure compliance with the standards and collects specific metrics related to the certificants, examination instruments and the organization’s activities. Then every five-years, all NCCA accredited certification programs are required to go through a complete re-accreditation process to demonstrate compliance with the rigors of proper certification programs.
The Coalition for the Registration of Exercise Professionals® (CREP) has made significant progress in 2014. The organization has grown the United States Registry of Exercise Professionals® (USREPS) to over 160,000 including all NCSF certified personal trainers. Now qualified professionals from NCCA-accredited, member organizations have a new distinction to go along with the credential verification and acknowledgement of registration, as CREP releases the registered exercise professional badge. The new “Find Me” Badge is a digital mark which functions as an electronic visual representation verifying all current exercise professional credentials listed in the USREPS®.
For most exercisers, a bottle of sports drink is an essential sidekick during a working out. While most people may feel that a sipping a sports drink during physical activity will improve performance, it might come as a surprise that the research is not as clear cut. Any potential improvements in exercise performance are greatly dependent on the type, intensity and duration of exercise.
For most personal trainers, limited training volume is a significant constraint when it comes to helping clients achieve their goals, making time management a key factor for success. One option to aid in time limitations is the use of supersets. While most trainers are familiar with the training system, many are not as versed in contrast sets. Contrast sets are an intermediate to advanced training system using the superset concept for a specific adaptation purpose; improved strength and power.
How much is too much? That is not always a question that we ask ourselves when it comes to exercise. However, recent research made international headlines when it suggested that jogging too much is just as bad for your health as being inactive. This novel study supports prior research linking excessive exercise with health issues. However, what is substantial about the new report in the Journal of the American College of Cardiology is that the investigators were able to identify an “ideal time range” and an “ideal speed” for jogging to improve health.
Consuming certain foods may improve your body’s ability to oxidize fat. An investigative study in the Journal of Nutritional Biochemistry (January 2015) found that consuming dark-colored grapes - either as whole fruit, juice or wine – drastically hindered fat cell growth and formation, as well as increased fatty acid metabolism in the liver. The researchers were able to isolate a specific compound found in the grapes, ellagic acid, that proved to have the highest impact on fat cell metabolism.
