05). LV longitudinal and radial PDSR were correlated with LA reservoir and conduit function (all P<0.01). Among all LV and LA impaired deformation parameters, the longitudinal PDSR (in LV) and εe (in LA) were the most sensitive parameter for the discrimination between non-LVH and healthy volunteers, with an area under the curve of 0.70 (specificity 79%, sensitivity 55%) and 0.76 (specificity 95%, sensitivity 49%), respectively. The area under the curve reached 0.81 (specificity 82%, sensitivity 75%) combined with the longitudinal PDSR and εe.
CMR-FT could detect early LV diastolic dysfunction in HTN patients, which might be associated with LA reservoir and conduit dysfunction.

Rago, V, Vigh-Larsen, JF, Deylami, K, Muschinsky, A, and Mohr, M. Use of rating of perceived exertion-based training load in elite ice hockey training and match-play. J Strength Cond Res XX(X) 000-000, 2020-Training load (TL) based on the subjective rating of perceived exertion (RPE) may be a useful athlete monitoring alternative when wearable technology is unavailable. The aim of this study was to examine the validity of RPE-based TL monitoring in elite ice hockey. A male ice hockey team (n = 18) was monitored using a 200-Hz accelerometer, heart rate (HR) and RPE (0-10 scale), throughout a 4-week competitive period (n = 309 individual observations). Session-RPE (RPE × duration) averaged 244.8 ± 135.2 and 728.6 ± 150.9 arbitrary units (AU) during practice sessions and during official games, respectively. The smallest worthwhile change was 19.8 AU. Within-individual correlations between session-RPE and total accelerations >0.5 m·s-2 (Acctot), accelerations >2 m·s-2 (Acc2), total decelerations >-0.5 .001). In addition, correlations between RPE and measures of exercise intensity (Acctot per min, Acc2 per min, Dectot per min, mean HR, and peak HR) were small (r = 0.02-0.29; p less then 0.05) except for Dec2 being unclear (p = 0.686). Differences in intensity parameters between RPE range (easy to very hard, 2-7 AU) were small (r = 0.22-0.31; p less then 0.05). The session-RPE method can be used as a global indicator of TL in ice hockey. Specific ranges of time-motion and HR intensity variables can be demarcated between RPE categories (easy to very hard; 2-7 AU). Accounting for training volume (session-RPE) more accurately reflects objective methods of TL based on accelerative efforts and HR, than the RPE score (based on the perception of the intensity).
Elhaj, HM, Imam, O, Page, BW, Vitale, JM, and Malek, MH. Perceived consumption of a high-dose caffeine drink delays neuromuscular fatigue. J Strength Cond Res XX(X) 000-000, 2020-The placebo effect is a concept in which a desired outcome arises, mainly from the belief that the treatment (i.e., supplement or drug) was beneficial although no active ingredient was given. The results of studies related to the placebo effect primarily examine functional performance. What remains unanswered, however, is whether these changes in performance are associated with neuromuscular alterations in the exercised muscles. The purpose of the study, therefore, was to determine the influence of the placebo effect on the physical working capacity fatigue threshold (PWCFT) for a continuous exercise paradigm. To achieve this aim, subjects were told that they were participating in a study to determine the dosage response (low or high) of caffeine on neuromuscular fatigue when in fact no caffeine was given during the experiment. We differences (all p-values less then 0.01), for PWCFT, between the other conditions (mean ± SEM placebo 23 ± 3 W, low-dose caffeine 26 ± 2 W, and high-dose caffeine 42 ± 3 W). This corresponded to a significant mean difference (all p-values less then 0.01) when the PWCFT was presented as a percentage of the maximal power output (mean ± SEM placebo 37 ± 5%, low-dose caffeine 42 ± 3%, and high-dose caffeine 64 ± 3%). The application of our results may indicate that the subject's expectancy, to caffeine consumption, plays a critical role in delaying the onset of neuromuscular fatigue despite not receiving any caffeine in their drinks.Anxiety disorders are highly prevalent and can cause serious functional impairment. Tertiapin-Q in vivo Cognitive-behavioral treatments are effective but they are not always readily available. One factor contributing to this problem is the large number of disorder-specific treatments that require a high level of clinician training and resources, despite the similarity in the mechanisms underlying the various anxiety disorders and their treatments. Group-based, transdiagnostic cognitive-behavioral therapy (TCBT) has been shown to reduce the burden on clinicians while maintaining strong positive treatment outcomes. Furthermore, long courses of treatment may limit some individuals' ability to participate because of issues related to transportation, work, or childcare. Research has supported the efficacy of brief, intensive treatment for anxiety. The goal of the study presented here was to combine these 2 innovative treatment modalities by examining the feasibility and acceptability of TCBT provided in an intensive weekend format. The results of this pilot study indicated that this format was acceptable to a sample of Veterans (N=13) based on their feedback. This pilot study also demonstrated that the format was feasible, as all Veterans who initiated treatment completed the entire program (N=8). Preliminary outcome data suggested that TCBT delivered in an intensive weekend format may have positive effects for individuals with anxiety, including reduction in symptoms of anxiety and depression as well as improved overall functioning. Clinical implications and directions for future research are discussed.Diego Velazquez painted several dwarfs employed at the Royal Court of Spain and one of the best known among them is the painting of Sebastian de Morra, a court jester. The clarity of the painting enables the reader to make a diagnosis of achondroplasia.
