Heart rate variability in young swimmers was negatively correlated with anxiety in the high-frequency component (r = -0.55, p < 0.01) and with performance in parasympathetic indices.

Is heart rate variability associated with psychological variables and performance in young swimmers?
Heart rate variability may be a valid tool for predicting performance and interpreting psychometric tests in young swimmers.
Effect estimate: r = -0.55
p-value: p=<0.01
Correct interpretation of performance markers from a psychophysiological perspective is important in young developing athletes. This study had two objectives. The first was to analyze the relationship between heart rate variability (HRV) and the psychological variables sleep quality, self-esteem, and mood states in young swimmers from a professional swimming club. The second was to study the relationship between performance and HRV and psychological determinants. The sample was composed of nine swimmers (11.7±1.4 years) base on purposive sampling method. Data were collected once a week during training sessions for 3 weeks. The statistical analysis showed that anxiety was negatively correlated with the high frequency component of HRV (Ln HF) and positively correlated with the very low frequency component (Ln LVF). No significant correlations were observed for self-esteem or sleep quality. Performance in a 200-m freestyle event was negatively correlated with the parasympathetic HRV indices. Our results suggest that HRV could be a valid tool for predicting performance and improving interpretation of psychometric tests.
Ortigosa-Márquez et al. (Fri,) conducted a observational in Healthy young swimmers (n=9). Heart rate variability (HRV) monitoring was evaluated on Correlation between anxiety and high-frequency component of HRV (Ln HF) (r = -0.55, p=<0.01). Heart rate variability in young swimmers was negatively correlated with anxiety in the high-frequency component (r = -0.55, p < 0.01) and with performance in parasympathetic indices.
