Independent experimental manipulation of subjective intensity and hedonic tone is required if one wants to study their separate effects on brain activity and behavior. This is problematic because hedonic tone and subjective intensity are related, leading to a pleasantness change each time the stimulus intensity is altered. In the present study, a solution to this problem was explored by combining a pleasant-tasting substance (sucrose) and a bad-tasting substance (quinine sulfate) into a number of different isointense mixtures. Here we show that subjective intensity as well as pleasantness can be accurately predicted, particularly in midrange, only if one corrects for mixture suppression.

Objective: The aim of the study was to analyze the effects of 16 weeks of Jazz Dance training compared to a control group in postmenopausal women, postintervention, and at the 6- and 12-month follow-ups, on cardiorespiratory fitness, body composition, muscle strength, and sleep quality.
Methods: Two-arm randomized clinical trial with a total of 47 women (jazz dance intervention group [JDIG] [n = 23] and control group (CG) [n = 24]) with a mean age of 53.41 ± 2.

Background: Chronic pain is defined as any persistent or recurring pain lasting longer than 3 months that significantly affects a person's quality of life. Millions worldwide are impacted by chronic pain, but its subjective nature makes it difficult to quantify and compare between individuals.
Methods: This retrospective analysis aimed to examine the differences in pain perception and reporting between male and female patients, as well as how their pain was managed.

The sensory/discriminative domain of pain is often given more consideration than the cognitive and affective influences that ultimately make pain what it is: a highly subjective experience that is based on an individual's life history and experiences. While many investigations of the underlying mechanisms of pain have focused on solely noxious stimuli, few have compared somatosensory stimuli that cross the boundary from innocuous to noxious. Of those that have, there is little consensus on the similarities and differences in neural signaling across these sensory domains.

Purpose: To describe warning signs, monitoring tools, and training- and non-training-related actions taken by world-class endurance coaches in cases of underperformance.
Methods: Twelve highly acclaimed male Norwegian coaches known for coaching world-class endurance athletes with a remarkable collection of over 350 Olympic, World, and European Championship medals-primarily with Norwegian athletes-participated in the study. Data collection and analyses followed a 3-step pragmatic qualitative study design, including an initial questionnaire, in-depth interviews, and structured negotiation between researchers and coaches.

Background: Modern elite football places extremely high demands on the athlete's body, so it is of practical interest to study the effect of various dietary supplements on load tolerance and postexercise recovery. Furthermore, there is a lack of research on the effects of caffeine on key measures of load tolerance in football such as delayed-onset muscle soreness (DOMS), rate of perceived exertion (RPE) and heart rate (HR) at different time points after the exercise.
Methods: 54 young players aged 15-17 years from a leading Russian football academy took part in a randomised trial using the balanced placebo design.
