alanine can increase agility, muscular endurance and power in the lower body.
The experts from the United States Sports Academy in Alabama, the University of
Oklahoma, and the University of South Alabama in Nutrition & Metabolism
have stated, "This investigation was the first to examine the effects of the
pre-workout supplement, Assault, on a multi-faceted exercise testing protocol."
The study was
financially aided by the supplement manufacturing company- the MusclePharma.
The supplements of MusclePharm make up most of the US market. It accounts for
about 5% of the entire market, as reported by the Leatherhead Food Research.
Brandon Spradley et al
conducted the study for which 12 recreationally- trained men, aged between 28
and 30 years voluntarily participated for a period of three weeks.
Twenty minutes before
their exercise regime, the men were given either a placebo or supplement. Their
exercise regime included one-rep maximum (1-RM) for bench and leg press,
intermittent velocity tests and choice reaction test.
a main ingredient of the supplement, Assault, is a mild stimulant that affects
the central nervous system and has the potential to influence human
neuromuscular performance. In an attempt to maximize the effectiveness of
caffeine, supplement manufacturers often combine several ingredients, possibly
enhancing caffeine's stimulatory potential.The researchers observed that such
ingredients contained amino acids
, both of which
were a part of Assault supplement.
The experts finally concluded that, "From a practical
perspective, college-age males who recreationally participate in sports where
auditory stimuli are abundant, such as team sports where verbal cues are
encouraged may experience increases in performance after ingesting the
pre-workout supplement used in the current study (Assault)."
the consumption of a pre-workout supplement containing caffeine, amino
acids, creatine, beta-alanine and B-vitamins could delay the fatigue while
increasing the muscular endurance and reaction time.
