Abstract	It is commonly assumed that performance is impaired by pressure and that different types of individual situational factors can produce equivalent pressure. Our aim was to explore the psychophysiological effects of pressure to test this assumption. Eighty-one novices completed a golf putting task under control and eight individual pressure conditions: time, difficulty, video, team, goal, fame, shame, and distraction. Performance was measured by the number of holed putts and ball-hole distance. Psychological, physiological and kinematic measures were collected. Performance was impaired by time and difficulty conditions but improved by team, goal and shame conditions compared to control. Perceived pressure and effort were higher than control in all conditions except distraction. Conscious processing was greater than control in all conditions except distraction and time constraint. Heart rate was faster with time, team, fame and shame. Heart rate variability and muscle activity were largely unaffected. Putter kinematics provided evidence of swing profiles slowing and/or becoming constrained in conditions where conscious processing increased, while the swing became faster in the time-pressure condition where conscious processing was decreased. Taken together, these results reveal heterogenous effects of pressure on performance, with performance impaired, unaffected, and improved by individual pressure situations. Similarly, heterogeneity characterized the effects of pressure on psychological, physiological and kinematic responses associated with task performance. In sum, the evidence challenges the standard tacit assumptions about the pressure-performance relationship in sport.

Abstract	The growing demand among dairy producers for suitable beef sires to mate to their females creates the possibility of separate breeding programs to generate beef sires for the dairy sector versus those for the beef sector. Informing such a decision is the extent of the genetic differences among beef sires used by dairy producers relative to those used by beef producers. The objective therefore of the present study was to use a large national database of artificial insemination (AI) records in dairy and beef cow herds to establish the difference in mean genetic merit of beef AI sires used by dairy producers versus those used by cow-calf beef producers. The traits explored were gestation length, calving difficulty, and perinatal mortality as well as the 3 carcass traits of carcass weight, conformation, and fat score. Carcass conformation and fat score are mechanically assessed on a scale of 1 (poor conformation and low fat cover) to 15 (excellent conformation and high fat cover). Sire genetic merit differences for feed intake and docility were also examined. Estimates of genetic merit for all 8 traits on individual AI sires available at the time of service were used. A total of 1,230,622 AI records comprised 909,719 services from dairy herds and 320,903 services from beef herds were used. Of the 1,802 beef AI sires represented in the entire dataset, over half were used by both dairy and beef herds representing ≥98% of the services in each production system. However, the usage rate of individual AI sires differed between dairy and beef herds with the Spearman rank correlation between the quantity of inseminations per sire in dairy and beef herds being just 0.38. This correlation means that beef AI sires used heavily in the beef herd were not always those heavily used in dairy herds. A clear difference in the mean genetic merit of beef AI sires selected by dairy producers relative to those selected by beef cow-calf producers was obvious with the extent of the difference being a function of whether the female served was a nulliparous heifer or a cow. Much of the differences in genetic merit of chosen beef AI sires between dairy and beef producers was actually attributable to differences in breed choice, albeit some within-breed selection was also evident. Irrespective, dairy producers, on average, chose shorter gestation length sires whose progeny were genetically less predisposed to require intervention during the birthing process; these sires had genetic merit estimates expected to result in lighter and less conformed progeny carcasses relative to the beef AI sires used by beef producers. Results point to large differences in genetic merit of the beef AI sires chosen by dairy versus beef producers, much of which actually reflected differences in breed choice among dairy and beef producers.

Abstract	The slowing of heart rate prior to movement onset has been presented as a marker of task-related cognitive processing and linked with performance accuracy. Here we examined this event-related bradycardia and task performance as a function of task difficulty. Forty experienced golfers completed a series of golf putting conditions that manipulated task difficulty by varying target distance, target size, and surface contour. Performance was measured by the number of holed putts and finishing distance from the hole. Physiological activity was recorded throughout. Analyses confirmed that performance varied as a function of task difficulty, worsening with longer distances to target, smaller targets, and sloping paths to target. Task difficulty also impacted the cardiac response, including the rate of heart rate deceleration, change in heart rate, and heart rate at impact. These heart rate metrics were found to correlate with performance strongly, moderately, and weakly, respectively. In conclusion, heart rate deceleration in the moments preceding movement onset was affected by task difficulty. Features of this cardiac deceleration pattern were characteristic of successful performance. Our findings are discussed in terms of the role of cognitive and motor processes during the execution of complex motor skills.

Abstract	The strength model of self-control purports to explain why brief cognitive response inhibition tasks impair subsequent isometric handgrip endurance. According to the model, ego depleting tasks requiring self-control resources impair performance on subsequent tasks that also require self-control resources. However, several lines of evidence challenge this model, including evidence of improved exercise performance following longer cognitive tasks. Our study investigated the effects of cognitive task duration on (1) subsequent physical endurance performance, (2) concurrent cognitive task performance, and (3) subsequent novel cognitive task performance. Adopting an experimental design, with Stroop task type (incongruent, congruent) and duration (5, 10, 20 min) as between-participant factors, participants (N = 180) completed a color word Stroop task, an isometric handgrip to exhaustion task, and a novel 5-min incongruent number word Stroop task. In the handgrip task, endurance performance was worse following incongruent word Stroop than congruent word Stroop for 10-min tasks but not 5-min and 20-min tasks. In the word Stroop task, accuracy was lower and speed was slower following incongruent word Stroop than congruent word Stroop. Importantly, reaction times improved with longer task durations. In the novel number Stroop task, accuracy was higher following incongruent word Stroop than congruent word Stroop. In conclusion, the finding that the ego depletion effect was moderated by cognitive task duration is better explained by the expected value of control model than the strength model.

Abstract	Background: During the COVID 19 pandemic, there were social restrictions with severe mental stress for a long time. Most studies on mental health consequences of the pandemic focused primarily on the beginning of the pandemic. The present study on families of patients or study participants of a child and adolescent psychiatry aimed to examine long-term profiles of emotions and worries in adults with and without mental health condition (mhc) during the first 1.5 years of the COVID-19 pandemic. Methods: We surveyed emotions and worries of 128 adults with (n = 32) and without (n = 96) pre-pandemic mhc over a 1.5-year study period from spring 2020 until summer/autumn 2021. Emotions and worries were captured at four time points: [i] pre-pandemic, [ii] spring 2020 (first lockdown was implemented), [iii] December 2020 (hard lockdown at Christmas time) and [iv] summer/autumn 2021 (considerable ease of regulations); [i] pre-pandemic and [iii] December 2020 were measured retrospectively). First, we run non-parametric tests to compare emotions and worries between adults with and without pre-pandemic mhc at the four time points. Next, we conducted latent profile analysis to identify subgroups from the total sample who share similar trajectories of emotions and worries. Finally, a logistic regression analysis was run to examine whether socio-demographic and psycho-social factors were related to identified trajectories of emotions and worries. Results: Adults without pre-pandemic mhc reported a strong worsening of emotions and worries at the beginning of the pandemic and a lower worsening during the course, while adults with pre-pandemic mhc reported a constant worsening of emotions and worries. The latent profile analysis revealed three profiles of adults who show either i) an adaption, ii) no adaption or iii) a continuous high condition. With increasing age, higher perceived stress and pre-pandemic mhc, the likelihood of an adaption was increased. Conclusion: The results of the present study suggested that adults (both with and without pre-pandemic mhc) coped the crisis with different strategies and that most of them returned to their initial, pre-pandemic levels of emotions and worries when social restrictions were considerably eased or stopped.

Abstract	Objective: A better understanding of the degree to which social health factors contribute uniquely to statistical clusters associated with variation in levels of capability might inform targeted whole person care strategies for more comprehensive management of musculoskeletal health. Therefore, we asked: (1) What are the statistical groupings of social and mental health measurements in patients seeking specialty care for musculoskeletal conditions? (2) Do identified psychosocial groupings correspond with different mean magnitudes of incapability accounting for demographic and clinical factors? Methods: We included 158 patients seeking musculoskeletal specialty care and collected measures of magnitude of incapability, unhelpful thoughts and distress regarding symptoms, symptoms of depression, symptoms of anxiety, and social health. A k-means clustering algorithm was fit to the data and a linear regression model compared mean PROMIS-PF CAT scores for grouping. Results: A quantitative social health measure contributed to 4 statistical clusters as follows: 1) relatively low levels of all mental health measures and high social health; 2) greater unhelpful thoughts and distress regarding symptoms, average symptoms of general anxiety and depression, and average social health; 3) higher levels of all mental health measures and severely compromised social health; and 4) severely compromised mental health and lower social health. Magnitude of incapability was significantly greater for groups with worse mental and social health. Conclusion: The finding of a relatively independent association of social and mental health factors with greater incapability supports the importance of introducing comprehensive health strategies in musculoskeletal specialty care. Strategies may include mindset training and case management of social unmet needs. Level of evidence: Level III; Cross-sectional study.

Abstract	Purpose: Given the stigma surrounding mental health, a discussion of how symptoms interfere with sleep might be a useful first step to identify unhelpful thoughts or feelings of distress. We asked: 1) Does sleep quality have an association with magnitude of incapability and pain intensity independent of mental health? and 2) Are mental health factors associated with sleep quality? Methods: We performed a cross-sectional study of one hundred and fifty-four patients seeking musculoskeletal care who completed measures of magnitude of capability, pain intensity, unhelpful thoughts regarding symptoms (catastrophic thinking, negative pain thoughts), distress (symptoms of anxiety and depression), and sleep disturbance. We tested factors associated with the magnitude of capability and pain intensity, accounting for sleep quality and mental health in multivariable models. Results: Accounting for potential confounding in multivariable analysis, lower magnitude of capability was independently associated with greater sleep disturbance, more unhelpful thoughts about symptoms (negative pain thoughts), and older age. Greater pain intensity was independently associated with greater unhelpful thoughts about symptoms (catastrophic thinking) and not using of an electronic device before bed. Greater sleep disturbance was independently associated with use of sleep medication, greater symptoms of anxiety, and greater unhelpful thoughts regarding symptoms (PCS). Conclusion: Given the observation that sleep disturbance is associated with feelings of anxiety, clinicians can consider starting mental health discussions by focusing on sleep quality. App and web-based cognitive behavioral therapy-based treatments for sleep are readily available and have the potential to improve mental health.
