The use of Heart rate variability (HRV) has become increasingly popular as a non-invasive methodology that provides an indirect insight into the autonomic nervous system. HRV can be utilized as a diagnostic tool in detection of autonomic nervous system impairment and sympatho-vagal imbalance. HRV technology is employed to monitor the internal response of athletes to workload and identify athletes’s psychophysical stress to predict and therefore prevent injuries. Objective: The objective of the investigation is to establish whether the use of Polar H10 sensor heart rate monitors worn by athletes in a sitting position (inclination 60 degrees) during periods characterized by stress can provide a valid and non-invasive method to assess the psychophysiological state during sports competition and school exams. Method and Statistics: In the study, the HRV of 12 basketball students athletes and 4 students non-athletes was analyzed as a control group. The autonomic nervous system activity was assessed based on heart variability parameters (HRV): SDNN, rMSSD, LF, HF, and LF/HF. The measurements were made after establishing the baseline at rest, during the training phase (CT), competition phase (CC) and during the acute phase of stressors due to school exams coinciding with the competitive season (CC + E). Results: Compared to the respective values prior to the stress of the competitions and exams, a significant decrease in HRV indices was found: SDNN (P Conclusions: The analysis and examination of the data on the sample of the student population also showed a statistically significant correlation between decreased cardiac variability and injuries or indisposition to physical exertion.展开更多

A secondary objective was to inform future measurement of identified factors. A sample of 20 intercollegiate athletes participated in an open-ended survey, followed by a corresponding focus groups (≈90-minute). Qualitative data were gathered relative to the factors impacting athletes’ excessive alcohol intake, fruit and vegetable consumption (FVC), and maintenance of physical activity after college. In general, participating athletes reported influences within their social and physical environments (friends, bar accessibility, etc.) as the leading enablers of their excessive alcohol intake, while individual level influences were the most salient reasons not to drink excessively (responsibilities, health, etc.). Individual characteristics (taste preference, health, and expense) and the physical environment (availability and accessibility) were reported as the most salient levels of influence on athletes’ FVC. And when anticipating future maintenance of physical activity, athletes mostly reported individual level influences (outcome expectation, intrinsic motivation, etc.), with mention of family and friend influences. An in-depth comparison of current outcomes to similar research among young adult and athlete populations is provided, including validated measurement scales and future research suggestions. Current results provide an essential foundation for progressive research examinations among similar populations.展开更多
