Concerns Are Raised After Tests Of NFL Helmets

Study shows NFL players wore low-rated helmets

      WASHINGTON (AP) – A study of football helmets by Virginia Tech
researchers gives its second-lowest rating to a model worn by
nearly 40 percent of NFL players last season.
      Researchers analyzed how much helmets reduced concussion risks,
and Riddell's VSR-4 helmet received just one star in the study
being released Tuesday.
      According to Riddell, 38 percent of NFL players used the
low-rated VSR-4 in 2010.
      Another Riddell model – the Revolution Speed – is the only
helmet that earned five stars, the study's top rating.
      Five models – two made by Riddell, two by Schutt and one by
Xenith – were given four stars.
      Virginia Tech professor Stefan Duma says his study is the first
in which comparative test results on football helmets have been
made public.
