If your answer to the question in the headline was “salt,” you are wrong, say authors of a published study in the online journal Open Heart [doi: 10.1136/openhrt-2014-000167]. Added sugars, particularly fructose, in processed foods are likely to have a greater role in high blood pressure, heart disease and stroke than added salt.

Before we can compare HIIT and continuous endurance training, it’s important to review how the body’s cardiovascular system adapts to an aerobic workout. During aerobic exercise, heart performance is based on heart rate, stroke volume (the amount of blood pumped per beat) and heart contractility (the forcefulness of each heart contraction). These variables increase blood flow and oxygen supply to meet the demands of exercising muscles.
Depression is an independent risk factor for heart disease, but little research has been done to determine whether treatment
of depression impacts the likelihood of cardiovascular diseases. Researchers from Indiana University-Purdue University, in Indianapolis, decided to evaluate whether depression treatment delivered before the start of clinical cardiovascular disease could reduce the risk of an event like heart attack or stroke.
Many mind-body movement professionals have encountered clients who have experienced a strong emotional release after holding an extended stretch or after moving the spine through forward, backward and/ or side-bending movements. Some people think these responses are related to fascia, the layer of tissue surrounding muscles, muscle groups, blood vessels and nerves.
The causes and consequences of iron-deficiency anemia (IDA) generate a lot of interest and discussion in the fitness industry. After all, IDA can degrade exercise capacity and health status (Schumacher et al. 2002), and adult endurance runners may experience a reduction in iron stores (Kong, Gao & Chang 2014).
No doubt personal trainers were surprised and confused after learning about a recent Annals of Internal Medicine study challenging the long-held association between saturated-fat intake and heart disease. Some media reports pounced on the study results, essentially giving green-light messages to eat more red meats and butter.
Should your clients take them, or shouldn’t they? Supplements, that is.
One day the news media are report- ing that dietary supplements don’t pre- vent disease and may actually threaten our health; the next day another study says that supplements can help to thwart disease or can fill nutrient gaps in our diets. What should health and fitness professionals tell clients when asked about supplements?
