PEMF is used by thousands of athletes to boost performance and endurance. It boosts cellular output of the energy molecule ATP (Adenosine Tri Phosphate). This cuts the time an athlete has to rely on energy from phosphocreatin stored in muscles, which produces performance-degrading lactic acid. PEMF also promotes higher levels of human growth hormone, and endorphins, our natural pain-killers. Regular energizing of stressed tissues is also thought to help prevent injuries.
