Temporary Tattoos Detect Lactate During Workouts

To prevent overexertion during exercise, University of California, San Diego researchers have developed a temporary-transfer tattoo that can detect lactate, a form of lactic acid, in an athlete’s sweat. Researchers hope to prevent a painful build up of lactate that occurs when muscles need more oxygen than the body can provide. This buildup of lactate causes athletes to experience extreme fatigue and pain. Tests on volunteers show that the tattoo accurately measured lactate levels during exercise and has the ability to warn wearers when it is time to get some rest.
