Key result
Aerobic swimming performance strongly correlates with parasympathetic HRV, while anaerobic performance tracks psychological traits.
Why the study?
The study was conducted to evaluate the psychological and physiological features associated with aerobic and anaerobic performance in trained swimmers.
Cross-Sectional (n=20)
Different psychological and physiological features are associated with aerobic versus anaerobic swimming performance, suggesting targeted monitoring based on the competition event.
Background: The aim of the present research was to study the psychological and physiological features associated with aerobic and anaerobic performance in trained swimmers. Methods: A correlation and stepwise regression analyses were conducted with the data obtained in a RESTQ-76 sport questionnaire, a heart rate variability test, and an anaerobic and aerobic swimming performance efforts of 20 swimmers. Results: Aerobic performance correlated, principally, with parameters related to parasympathetic modulation measured in the frequency and time domains of the heart rate variability (LF/HF r: −0.806, p < 0.001; NN50 r: 0.937, p < 0.001). Swimmers’ anaerobic performance correlated to psychological features (low stress r: 0.526, p: 0.025, and high fatigue r: −0.506, p: 0.032). Conclusion: Swimming performance presented different psychological and physiological features depending on the probe characteristic. Specifically, swimmers’ anaerobic performance was associated with psychological features (low stress and high fatigue perception) and aerobic performance with physiological features (high parasympathetic modulation). This information could help coaches to know the variables to control in their swimmers, depending on the probe in which they compete (anaerobic or aerobic).

Clemente‐Suárez et al. (2021) conducted a cross-sectional in Healthy trained swimmers (n=20). Psychological and physiological features was evaluated on Correlation between aerobic performance and parasympathetic modulation (NN50) of heart rate variability (r 0.937, p=<0.001). Aerobic swimming performance was strongly correlated with parasympathetic modulation of heart rate variability (NN50 r=0.937, p<0.001), whereas anaerobic performance correlated with psychological features.
