Shockingly in Shape

From reading my personal trainer review booklet, I have refreshed my memory about a piece of modern technology tool, Bioelectrical Impedance Analysis Machine, that measures an individual’s body composition. This tool sounds more sophisticated than its simple design. Bioelectrical Impedance Analysis Machine measures one’s body fat percentage by electrical current that passes through his or her body. The machine considers fat-free tissue as a good conductor of electricity; therefore, anybody with low body fat percentage would have a greater current passing through the body comparing to a deconditioned or unfit individual. ( Of course, fat tissue would be considered as a poor conductor of electricity.) A fitness fanatic like myself just can’t wait to get my hands on that toy someday. If you happen to be lucky enough and have the access to the machine, do me a favor, don’t cheat yourself and drink two gallons of water before going into the testing. Here’s the pre-test protocol to ensure accurate measurement:

  • Abstain from eating or drinking within 4 hours of the assessment
  • Avoid moderate or vigorous physical activity within 12 hours of the assessment
  • Void completely before the assessment
  • Abstain from alcohol consumption for 48 hours before the assessment
  • Avoid diuretic agent, including caffeine (going to be tough for me), prior to the assessment unless prescribed by a physician

Note: above pre-test protocol is given by ACE’s Personal Trainer Exam Review Workshop verbatim
