Track and field athletes have a couple different options for warming up before training or competition. One popular protocol involves dynamic stretching, and a study published in the International Journal of Sports Medicine recently tested its potential on 12 healthy volunteers.
Subjects applied four 30-second sets of dynamic stretching to ankle joints. Measurements taken before and after the warm up showed increased range of motion immediately after stretching. The effect lasted for 15 minutes without changing the mechanical properties of muscle tendons.
How often do you read the facts panels on packages of food and beverages you consume? If they were easier to understand, would you use them more often? The French High Council for Public Health believes a 5-color nutrition label is the most effective, and a study published in the journal Nutrients explains why.
Each product is rated on a scale of green, yellow, orange, pink and red, based on levels of calories, sugar, saturated fat, sodium, fiber, protein and amounts of fruits and vegetables per 100 grams. Basically, this system helps factor all those things into one simple color representing good, bad or somewhere in between.
A web-based questionnaire tested consumer responses to frozen fish, pizza, dairy, breakfast products and appetizers and found that people who typically make bad food decisions had a much easier time figuring out what was their most nutritionally sound choice with this 5-color system.
