Pre-Exercise Stretching Decreases Strength

Athletes ranging from gymnasts to sprinters usually stretch before exercise.The need to “stretch out” before practice or competition is drilled into athletes from the earliest exposure to sports. In spite of an almost universal belief that stretching is essential, we have very little evidence that it does any good. In fact, many recent studies show that pre-exercise stretching decreases muscle strength and power, impairs jumping performance, causes muscle fatigue and increases the perception of effort during weight training. University of Nebraskascientists found that stretching decreased muscle strength at fast and slow speeds of motion. Stretch your muscles after training or competition when they are warm and performance is not critical. Warm up by doing gentle range-of-motion exercise that is specific to the movements used in the sport.

HOW CANDAIRY HELP ME LOSE WEIGHT?

I am sure plenty of you are skeptical about eating more dairy to peel off pounds, as you well should be.Reserchers haven’t quite solved this mystery either,but they have some good theories on how dairy may work to speed up the fat-burning process.

High calcium levels in fat cells have been shown to actually prevent fat from being used and increase fat storage. This would seem to to contradict the theory that calcium is good for you,which is why calcium’s role in weight loss is often referred to as the “calcium paradox”.

It turns out that when calcium levels in the blood are low,signals are sent to the brain to increase the amount of the mineral that enters intofat,which then prevents fat breakdown. But when calcium levels are adequate,these signals to the brain are decreased,allowing fat stores to be used.As a result,eating plenty of foods that are rich calcium wil ensure that your calcium levels are kept high,decreasing signals that prevent fat breakdown and increase fat storage.
