Go ahead, stretch before you run, but not for too long. A study published in the journal of the American College of Sports Medicine (ACSM) said short periods of stretching before exercise will not likely lead to a deficit in muscle strength Replica Vacheron Constantin watches and performance, and may actually increase range of motion in your joints.In the study, moderately active, nonathletes stretched their lower legs and ankles for periods of two, four and eight-minutes. The participants were tested before and after exercise, and 10, 20, and 30 minutes after stretching.

In moderately active individuals, short durations of stretching seem to temporarily improve flexibility without the detrimental strength losses that have been previously reported, said Eric Ryan, the studys lead author. Pre-competition stretching became controversial due to what has been reported as decreases in performance, however, future Replica A Lange&Sohne watch research still needs to determine how these stretching durations may impact athletes.So how long should you stretch? Joel T. Cramer, Ph.D., another of the studys authors, said stretching before exercise for less than 8 minutes would likely not decrease muscle strength during exercise. What stretches are best?

Mile High Music Festival drew in nearly 100,000 fans in its first-ever occurrence thanks to a solid, well-balanced line-up, a large enough venue to keep from constant shoulder-bumping, good traffic flow, weird art installations, and enough food, water, and beer (!) to keep the crowd happy and hydrated. On a small, you-cant-camp-here scale, this swiss replica watches festival rivals Bonnaroo thanks to names like Tom Petty and the Heartbreakers, Dave Matthews, Jason Mraz, OAR, and The Black Crowes. --Alicia CarrCheck out our re-cap here featuring Michael Franti Spearhead, John Mayor, and a few sneak appearances from the headliners:
