AbstractIn the sport context, recovery has been characterized as a multifactor process (physiological, psychological, behavioral, social, etc.). This study takes a multidisciplinary approach to find psychophysiological markers of the stress-recovery process. It aims to determine how athletes’ specific recovery actions relate to their perceptions of recovery, and Heart Rate Variability (HRV). A total of 196 assessments were analyzed from 6 players on a men’s professional basketball team within the Liga LEB Oro basketball federation (2012/2013 season). Perceptions of recovery, recovery strategies, and HRV were recorded. The results show a pattern of individual differences in behavior related to athletes’ recovery actions and HRV profiles throughout the season (p < .05). Moreover, we observed that each player had different recovery needs. In light of these results, we suggest an individualistic approach to evaluating and monitoring recovery to attend more accurately to each player’s recovery needs.

Abstract Introduction There are substantial individual differences (resilience and vulnerability) in neurobehavioral performance from psychosocial stress and sleep loss. However, the time course of heart rate variability (HRV) across baseline, total sleep deprivation (TSD), the combination of TSD + psychological stress, and recovery has not been investigated; in addition, it remains unknown whether HRV and blood pressure (BP) differ in resilient vs. vulnerable individuals and predict individual differences in cognitive performance. Methods Thirty-one healthy adults (ages 27–53; mean±SD, 35.4±7.1y; 14 females) participated in a five-day experiment consisting of two 8h time-in-bed (TIB) baseline nights, 39h TSD, and two 8h-10h TIB recovery nights. A modified Trier Social Stress Test (TSST) induced psychological stress on the TSD day. Systolic and diastolic BP and HRV (derived from echocardiographic R-R interval) were obtained at six time points (pre-study, baseline, during TSD, during TSD after the TSST, after recovery, and post-study). Cognitively resilient (n=15) and vulnerable (n=16) groups were defined by a median split on 10-minute Psychomotor Vigilance Test (PVT) TSD performance [total lapses (&gt;500ms response time) and errors]. Repeated measures ANOVA and post-hoc comparisons corrected for multiple testing, examined BP and HRV across time points between groups. Results HRV showed a significant time*group interaction: while resilient individuals had significantly lower HRV at pre-study compared to vulnerable individuals, their HRV increased above that of vulnerable individuals with TSD and with TSD + psychological stress. By contrast, systolic and diastolic BP did not show significant time*group interactions and did not predict cognitive vulnerability during TSD. Conclusion HRV differed between resilient and vulnerable individuals across TSD, psychological stress and recovery sleep and predicted individual differences in cognitive performance, whereby lower HRV during full-rested conditions predicted resilience to TSD and TSD + psychological stress. HRV, but not BP, is a reliable biomarker of sleep deprivation, psychological stress, and neurobehavioral vulnerability. Support NASA NNX14AN49G.

Frontal midline (FM) theta (4–8 Hz) reactivity to unexpected social rejection seems to be an important correlate of a neural threat-detection system. Neurovisceral integration theory proposes that the functioning of such systems is indexed by heart rate variability (HRV). Here, we tested this by examining whether baseline HRV predicts FM-theta reactivity to unexpected rejection feedback. Additionally, we examined whether this alleged heart-brain connection differs based on individual differences in personality and behavioral constructs relevant to social threat sensitivity. Female undergraduates (n = 149; mean age = 19.7 years) performed the social-judgment paradigm, where they communicated their expectations about being liked/disliked by unfamiliar peers who had allegedly evaluated them, and received peer-feedback indicating social acceptance/rejection. We used community structure analysis to subtract subgroups, based on self-esteem, social feedback expectations, and response speed of providing expectations. Results provided evidence of two distinct subgroups: optimistic vs. pessimistic in light of social threat. Baseline HRV did not predict FM-theta reactivity to unexpected rejection, and this relationship was not modulated by the subgroups. Both subgroups showed a significant FM-theta power increase following unexpected rejection. Additionally, the optimistic subgroup was uniquely characterized by a FM-theta power increase following rejection (as against acceptance) feedback. Supporting prior studies, our results suggest that enhanced FM-theta signals the need for cognitive control when faced with unexpected outcomes, and extend this by suggesting that differences in social threat sensitivity may determine whether an outcome is deemed meaningful enough to signal the need for cognitive control.

Abstract. Emotional stimuli automatically capture attention in ways that are relevant to the survival value of the stimuli. We have previously shown that individual differences in resting heart rate variability (HRV) were related to attentional capture by negative (fearful) and neutral distractors. However, different negative emotions such as fear and disgust may differentially capture attention. In the present study we investigated the effect of automatic attention capture by disgust and fear stimuli on behavioral and phasic heart rate responses as well as its relationship with resting heart rate variability (HRV). Twenty-eight participants (14 men) were divided into two groups based on their resting HRV. Phasic cardiac responses as well as reaction times and errors on a digit categorization task were assessed with disgust, fear, and neutral pictures as distractors. In the high HRV group disgusting distractors produced the strongest interference on the ongoing cognitive task indicated by more errors and longer reaction times as well as a deeper cardiac deceleration compared to fearful or neutral distractors. In contrast, the low HRV group showed faster reaction times to fear evoking pictures, whereas their heart rate responses and number of errors did not distinguish between the three emotional categories. Our results suggest that high HRV participants showed the emotional context appropriate responses while low HRV participants seem to be hypervigilant to fear.
