Are intense feelings of helplessness/hopelessness associated with decreased heart rate variability in championship chess players?
Are intense feelings of helplessness/hopelessness associated with decreased heart rate variability in championship chess players?
Intense feelings of helplessness and hopelessness are associated with reduced high-frequency heart rate variability, suggesting vagal withdrawal and providing a potential link between negative mood states and cardiac events.
May signal vagal withdrawal during acute stress; leaves open whether this predicts cardiac events in non-clinical groups.
OBJECTIVE: Clinical observations suggest that negative affects such as helplessness/hopelessness (HE/HO) may induce autonomic duration; affects were assessed for every move after reconstruction of the games. In all games compiled, 18 situation of intense confidence/optimism and 20 of intense helplessness/hopelessness were observed. RESULTS: Intense affects of HE/HO were associated with decreasing HF-HRV (Fisher exact test, p =.003), increasing "nervousness" (p =.0005), decreasing "optimism" (p =.0005), and decreasing "calmness" (p =.0005). CONCLUSIONS: Investigation of championship chess game players with an ELO strength > or = 2300 in a natural field setting revealed increasing HE/HO being associated with reduced HF-HRV suggestive of vagal withdrawal. Thus, our data may help link negative mood states, autonomic nervous system disturbances, and cardiac events.
