Analysis on the Amount of Physical Activities of Taekwondo Taegeuk Pumsae Using Accelerometers

This study measured and analyzed the amount of exercise in performing the basic pumsae of taekwondo, namely, taegeuk pumsae Chapter 1 through 8 using an accelerometer, calculated energy consumption from the amount of exercise, and proposed it as an indicator of exercise prescription for successful aging. We attached an accelerometer armband to 39 subjects of the experiment (28 males and 11 females) and had them perform taekwondo basic pumsae, namely, taegeuk pumsae Chapter 1 through 8. Sampled data were peak transverse acceleration (PAT), peak longitudinal acceleration (PAL), mean heat emission (HFA), mean skin temperature (STA), mean transverse acceleration (TAA), mean longitudinal acceleration (LAA), ambient temperature (CTA), the mean of the absolute value of variation in transverse acceleration (TMAD), the mean of the absolute value of variation in longitudinal acceleration (LMAD), steps per minute (SPM), skin conductivity (GSR), and energy consumption per minute (EE), and the sampling rate was one per second. In the results of analyzing acquired data with regard to the amount of physical activities and energy consumption of taegeuk pumsae, the mean TMAD was 7.83, the mean LMAD was 6.92, and the mean EE was 4.08. When taegeuk pumsae Chapter 1 through 8 was performed, energy consumption was around 120~210 cal.
