Never a big fan of supplements, Geezer cautiously passes along this news about research conducted at the University of California at Los Angeles and published in the Journal of the
International Society of Sports Nutrition and in WebMD: Cyclists who are 50 and older may be able to ride farther
and faster if they take a commercially available supplement, sold as Niteworks, containing
the
amino acid arginine and antioxidants. WebMD reports that 16 male cyclists aged 50 to 73 who were given
the
supplement showed a 16.7 percent increase in their anaerobic threshold at three
weeks, while their counterparts who received the placebo did not see any
increase in their anaerobic thresholds. Anaerobic threshold is the point
at
which lactic acid starts to accumulate in the muscles.
