Only 35 per cent of Australian professional footballers were able to identify the benefits of a supplement they were taking, and 48 per cent admitted to never reading the labels.
University of Queensland researcher surveyed 570 athletes for his .
“The athletes surveyed consisted of 303 from the , 180 from the and 87 from ,” Mr Kelly said.
“It’s practically unheard of to gain participation by that many professional footballers in Australia.
“What we found was that only 11 per cent completed their own research on beta alanine and 48 per cent said they never read the labels prior to ingestion.
“The majority of respondents were not using beta alanine in accordance with recommendations,” Mr Kelly said.
The study, conducted in 2010 and 2011 pre-dated sports doping allegations levelled at specific AFL and NRL clubs.
Beta alanine is purported to improve high intensity and intermittent exercise by preventing acidic accumulation and fatigue.
Significant proportions of the athletes wrongly associated the supplement with gains in cardiovascular endurance (20 per cent) and increased strength and muscle mass (16 per cent).
Many grossly underestimated the time required for beta alanine to take effect, with almost half of the NRL players surveyed believing it worked in less than 30 minutes, rather than two months.
“The reason why supplement companies love beta alanine is because it gives the consumer an instant physical sensation, one of pins and needles,” Mr Kelly said.
“That reinforces the idea that it must work somehow.
“Often you’ll hear athletes say things like ‘Give me some. I need the tingles’ even though it takes a prolonged time to make changes at a cellular level.”
In contrast to past studies on consumption of another popular supplement, creatine, where 75 per cent of consumers ingested too much, the Â鶹´«Ã½Ó³» study showed less than 20 per cent of athletes were taking beta alanine frequently enough or in large enough quantities to comply with recommendations.
Mr Kelly said the study, published in the , provided insights into group mentality and areas of opportunity for safer and more effective supplementation.
