Aerobic swimming performance correlated with parasympathetic modulation (NN50 r=0.937, p<0.001), whereas anaerobic performance correlated with psychological features like low stress (r=0.526, p=0.025).
Cross-Sectional (n=20)
Are psychological and physiological features associated with aerobic and anaerobic performance in trained swimmers?
Aerobic swimming performance is strongly associated with physiological parasympathetic modulation, whereas anaerobic performance is more closely linked to psychological factors like stress and fatigue perception.
Effect estimate: r 0.937
p-value: p=<0.001
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. (Sun,) conducted a cross-sectional in Trained swimmers (n=20). Psychological and physiological features was evaluated on Aerobic and anaerobic swimming performance (r 0.937, p=<0.001). Aerobic swimming performance correlated with parasympathetic modulation (NN50 r=0.937, p<0.001), whereas anaerobic performance correlated with psychological features like low stress (r=0.526, p=0.025).
