A Study of the Relationship Between Personality Type and Emotional Response to Athletic Injury
This investigation was designed to examine emotional response to athletic injury using personality constructs within reversal theory. Twenty-five (male = 19, female = 6) collegiate athletes, ranging in age from 18 to 22 years (mean = 19.95, SD = 1.11) who sustained a minimal criteria injury during a six-week data collection period participated in this study. Each athlete\u27s total mood disturbance (TMD) was measured pre-injury and post-injury using the Profile of Mood States (POMS). Athlete\u27s personality orientation was measured using the Paratelic Dominance Scale (PDS). A dependent t-test indicated a significant increase in TMD scores following injury (p \u3c 0.05), thus indicating overall mood disturbance in injured athletes. An independent t-test comparing paratelic and telic dominant athletes on TMD difference scores revealed non-significant results (p = 0.40). Methodological and theoretical reasons for this are examined and implications for further study of reversal theory and athletic injury are discussed
The influence of self-selected music on affect-regulated exercise intensity and remembered pleasure during treadmill running.
This study explored the influence of self-selected music on affect-regulated exercise intensity and Remembered Pleasure. Seventeen active male and female participants (28.1 ±9.9 years; BMI 23.8±3.2 kg/m2; VO2 peak 48.73±8.73 ml.min−1.kg−1) completed a maximal exercise test and each individual’s ventilatory threshold (VT) was identified. Following this, two treadmill exercise trials were performed at an intensity that was perceived to correspond to a Feeling Scale value of +3 (i.e. ‘good’). Sessions with either self-selected music or no music were completed 48 hr apart and in a randomized counterbalanced order. Affective responses (Feeling Scale) and heart rate were measured during exercise and Remembered Pleasure was measured 5-min post exercise. Results indicated that participants selected an exercise intensity that exceeded their VT during the two affect-regulated exercise sessions (p = .002, d = .99). Participants exercised with greater intensity during affect-regulated exercise with music than without (p = .045; d = 1.12) while maintaining a ‘good’ feeling. Furthermore, participants recalled the music session as more pleasurable than the no-music session (p = .001; d = .72). These results illustrate a positive ergogenic and psychological influence of music during affect-regulated exercise. Encouraging individuals to exercise at an intensity that feels ‘good’ elicits an exercise intensity sufficient to garner cardiorespiratory benefits and may lead to improved adherence. Moreover, the use of self-selected music appears to augment this effect.

Affective Responses to Increasing- and Decreasing-Intensity Resistance Training Protocols.
This study compared the effects of an increasing-intensity (UP) and a decreasing-intensity (DOWN) resistance training protocol on affective responses across six training sessions. Novice participants (Mage 43.5 ± 13.7 years) were randomly assigned to UP (n = 18) or DOWN (n = 17) resistance training groups. Linear mixed-effects models showed that the evolution of affective valence within each training session was significantly moderated by the group (b = -0.45, p ≤ .001), with participants in the UP group reporting a decline in pleasure during each session (b = -0.82) and the DOWN group reporting an improvement (b = 0.97; ps < .001). Remembered pleasure was significantly higher in the DOWN group compared to the UP group (b = 0.57, p = .004). These findings indicate that a pattern of decreasing intensity throughout a resistance exercise session can elicit more positive affective responses and retrospective affective evaluations of resistance training
See Hear: Psychological Effects of Music and Music-Video During Treadmill Running
© 2014, The Society of Behavioral Medicine.Background: There is a paucity of work addressing the distractive, affect-enhancing, and motivational influences of music and video in combination during exercise. Purpose: We examined the effects of music and music-and-video on a range of psychological and psychophysical variables during treadmill running at intensities above and below ventilatory threshold (VT). Methods: Participants (N = 24) exercised at 10 % of maximal capacity below VT and 10 % above under music-only, music-and-video, and control conditions. Results: There was a condition × intensity × time interaction for perceived activation and state motivation, and an intensity × time interaction for state attention, perceived exertion (RPE), and affective valence. The music-and-video condition elicited the highest levels of dissociation, lowest RPE, and most positive affective responses regardless of exercise intensity. Conclusions: Attentional manipulations influence psychological and psychophysical variables at exercise intensities above and below VT, and this effect is enhanced by the combined presentation of auditory and visual stimuli
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Motivational priming and positive affect during exercise: A replication study
This study aims to replicate findings of Pottratz et al. (in press) with a larger and more diverse sample of participants. Pottratz et al. (in press) showed that watching music videos with affective primes (positive valenced words) during a workout leads to significantly higher in-task affective valence, post-exercise enjoyment, remembered pleasure and forecasted pleasure compared to watching the same music videos without primes.
In contrast to the original study, data analysis in the replication study will be performed with hierarchical multi-level regression analysis, in order to account for the nested data structure
