| Abstract: | Females competing in individual sports are the group that experience the highest levels of competitive anxiety, which is the physiological factor that has the biggest influence on sports performance. A link had been found between heart rate variability (HRV) and anxiety. HRV biofeedback has found to be a promising intervention for reducing anxiety. Therefore, this project looked into the development of an HRV biofeedback tool to signal anxiety levels to female, competitive track & field athletes. This project provides a detailed overview on the factors that are needed to develop an HRV biofeedback tool. These factors include heart rate data acquisition and filtering, HRV measure determination and feedback determination and realisation. The most important conclusion is that the heart rate data to be acquired must cover the entire heart rate spectrum from minimum to maximum. Besides that, the calculation of time intervals between consecutive heart rate peaks must be possible, from which HRV measures can be derived. Finally, since the tool is to be used during sports movements, the measuring device must be able to handle EMG noise from muscle artifacts and preferably be wireless to allow for ease of wearing. Root mean square standard deviation (RMSSD) proves to be most accurate HRV measure for short-term measurements of 30 seconds when compared to the standard measurement time of 5 minutes for HRV determination. |
