Anotācija At present efficient training requires a complex approach incorporating the control of the exercise intensity and observation of athlete physiological variables. The heart rate monitoring during training session has become a common procedure, while more extensive investigation requires expensive technology and experienced personnel. Photoplethysmography (PPG) may be one of the potentially promising, simple and inexpensive techniques for acquisition of physiological parameters related to cardiac and arterial-hemodynamic activity. The aim of the current study is development end evaluation of a digital, multi-sensing photo diode technology based PPG device for telemetric monitoring of pulse wave parameters. Six young and healthy volunteers (21-23 y.o.) participated in this study. PPG signal has been recorded from the skin over the temporal artery in rest conditions, during veloergometry test and recovery period. The data has been processed and statistically analyzed with custom developed PPG waveform analyses software, providing information on PPG waveform related parameters, such as systolic peak time, relative amplitude, pulse duration, time to maximal ejection velocity, 78 | Marcinkevics et al: WEARABLE PHOTOPLETHYSMOGRAPHY ... etc. A reliable, low noise PPG signal has been obtained from all the subjects. Computed PPG signal waveform parameter changes reflected different physiological conditions (rest period, exercise, post-exercise recovery period) and were consistent with the values reported in the literature. We concluded that digital multi-sensing photo diode PPG device demonstrated high accuracy and convenient use, which suggests potential application in exercise physiology and training.
