Now a days everyone wants to get healthy body or physique instantly and in order to achieve that they rely on health supplements which exactly help them to do that. These days preworkouts are very famous among the fitness freak youths because they tends to increase the energy level, muscle power or endurance during your
workout.
Preworkout supplements
often contain a mystery blend of ingredients ranging from caffeine to guarana
to creatine. But do these supplements work, and are they safe to take?
It turns out that these
supplements may just change the way you feel while you're working out. Many of
the ingredients in preworkout supplements are intended to give athletes the
perception that their workout is supercharged, said Jordan Moonan exercise physiologist and sports nutritionist at the United States Sports Academy and Concordia University Chicago, and chief science officer at the fitness tracking.
"You've got
ingredients that are going to increase blood flow, increase heart rate,
increase focus, increase blood flow to the skin and give you a little tingle,"
But those physical
effects don't make people bigger, stronger or faster, Moon said.
And although some of
these supplements' ingredients — such as caffeine, creatine and beta-alanine —
have been shown to modestly enhance performance in extreme athletes and
bodybuilders, they only give people an edge if they are pushing themselves to
the limit, Moon said.
And some supplements
on the market may contain illegal and dangerous additives, such as
amphetaminelike stimulants. Even supplements that contain only legal
ingredients can include high levels of caffeine, which can have a negative
effect on the heart, recent testing by one independent lab found.
Creatine and amino
acids
Almost all preworkout
supplements contain creatine, which seems to boost energy production in muscle
cells and also seems to draw fluids from the blood plasma into the skeletal
muscle, which can improve muscle performance.
However, creatine must
be taken regularly in order to "build up" to sufficient levels, Moon
said. Taking it once or twice a week before a workout will not produce the
necessary level to have an effect, and it only works when people push
themselves hard during a workout.
Most "people who
go to the gym spend 90 percent of the time talking and resting over
lifting," Moon said. "They might not even be pushing themselves hard
enough to get any of the effectiveness of the ingredients."
Moon also said that
grading supplements based on testing the levels of their ingredients may be
misleading because there's no good research on what dose may be effective for
many of the supplement ingredients, some of which act synergistically.
"In the supplement industry, it's about
marketing; it's not about what's in the product," Moon said.
"Supplements don't really do that much unless you're already doing a lot
on your own."
