Cooper, JJ, Johnson, M, Radcliffe, J, and Fisher, J. Optimal emotional profiles for peak performance in strength and conditioning. J Strength Cond Res 35(3): 833-840, 2021-This study investigated athletes' performance-related emotions and emotional profiles for optimal performance in strength and conditioning (S&C). It is suggested that the identification and control of emotions associated with successful and unsuccessful performances are essential for achieving peak psychological states and optimal performance in sports-related tasks. The individual zone of optimal functioning (IZOF) model outlines an idiographic and comprehensive conceptual framework of interrelated dimensions that describe the structure and dynamics of subjective emotional experiences and performance-related psychobiological states. With institutional ethics approval, 13 competitive elite athletes (male, n = 7; female, n = 6: mean age = 21.7 ± 4.0 years) completed IZOF-based emotion profiling, in which subjects were asked to recall their perceived best and worst S&C session, outlining emotions and intensity within 4 global emotional categories. A significant difference was evidenced between best ever and worst ever performance within positive functional emotions (p < 0.001, d = 3.63) and negative dysfunctional emotions (p < 0.001, d = 4.92). Initial findings suggest that perceived peak performance states within S&C are associated with a high intensity of positive functional emotions (confident, motivated, and energetic) and a low intensity of negative dysfunctional emotions (worn out, sluggish, annoyed, and discouraged). Although future research is necessary to fully understand this area, the present data suggest that to assist athletes in achieving perceived peak performance states within S&C, psychological skills and strategies should be informed and developed in collaboration with sport psychologists, with the aim of achieving an optimal emotional profile.

High cardiac sympathetic drive and release of the sympathetic cotransmitter neuropeptide Y (NPY) are significant features of congestive heart failure (CHF), in which resting venous NPY levels are known to be associated with mortality. However, whether circulating NPY levels increase during exercise in CHF when they are already elevated is controversial. We sought to establish the dynamics of circulating NPY levels in CHF patients treated with contemporary medical therapy and devices in relationship to indices of performance linked to long-term prognosis.

Aims: To describe the sonographic features of active Charcot neuro-osteoarthropathy (CNO) and assess the potential role of ultrasound in identifying those with active CNO.
Methods: Using a prospective case-series study design we assessed the sonographic features of 14 patients with a diagnosis of diabetes presenting with clinical signs and symptoms suspicious for active CNO. Patients had standard weight-bearing plain X-Ray and, where possible, MRI to evaluate the presence of active CNO.

Background: Both listening to music during warm-up and consuming caffeine before exercise have been independently shown to enhance athletic performance. However, the potential synergistic effects of combining these strategies remain largely unexplored. To date, only two studies have reported additional benefits to combining music during warm-up with a caffeine dose of 3 mg/kg on taekwondo-specific performance tasks.

There is a pressing need to expand the production and consumption of alternative protein sources from plants, fungi, insects, and algae from both nutritional and sustainability perspectives. It is well known that the postprandial rise in plasma amino acid concentrations and subsequent muscle anabolic response is greater after the ingestion of animal-derived protein sources, such as dairy, meat, and eggs, than plant-based proteins. However, emerging evidence shows that a similar muscle anabolic response is observed-despite a lower and slower postprandial aminoacidemia-after the ingestion of alternative protein sources compared with animal-derived protein sources.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a well-known technique for polymer analysis, particularly for determining the molecular weight and structural details of dendrimers. In this study, we evaluated the performance of various matrices, such as 2',4',6'-trihydroxyacetophenone (THAP), α-cyano-4-hydroxycinnamic acid (HCCA), and sinapinic acid (SA), and their combinations, on the sensitivity and resolution of poly(amidoamine) (PAMAM) dendrimers of different generations (G3.0, G4.
