Bicycle engineering guidelines often used by state regulators to design bicycle facilities need to be overhauled to reflect current cyclists' preferences and safety data, according to a new study from Harvard School of Public Health (HSPH) researchers. They say that U.S. guidelines should be expanded to offer cyclists more riding options and call for endorsing cycle tracks – physically separated, bicycle-exclusive paths adjacent to sidewalks – to encourage more people of all ages to ride bicycles. http://medicalxpress.com/news/2013-05-track-policy-boost-ridership-health.html Health Thu, 16 May 2013 16:20:54 EST news287940047 The benefit of helmet legislation to reduce admissions to hospital for head injuries is "substantially uncertain," concludes a study published in BMJ today. http://medicalxpress.com/news/2013-05-benefit-helmet-laws-injuries-uncertain.html Health Tue, 14 May 2013 18:30:01 EST news287773633 Cyclists who don't wear a helmet are almost six times more likely to suffer a severe head injury than their helmeted counterparts, according University of Sydney research published in the latest issue of the Medical Journal of Australia today. http://medicalxpress.com/news/2013-05-cyclist-benefit-helmets-shown.html Health Mon, 06 May 2013 08:00:01 EST news287041882 Consumption of energy drinks containing caffeine may have beneficial effects on exercise but probably not for mental function.
