Purpose Previous research shows that endurance performance can be enhanced by placebo ergogenic aids. This study investigates the response, which we define as an increase in objective and physiological effort without subjective effort, competitive cyclists. The primary of this is to explore role supplement salience while secondary aim assess whether believing have taken inactive attenuates desired effect. Methods We employed a double-blind placebo-controlled design compared high (pudding)...
Previous studies have described the need for a tailored performance test to predict mountain bike performance. This should improve characterisation of intensive and intermittent physiological demands biking. Therefore, aim study was identify related parameters that can more accurately explain variance Ten competitive riders (age: 34 ± 8.7 years; VI‡O 2 peak: 69 11.1 ml·min −1 ·kg ) participated in following tests: (a) an incremental bicycle ergometer determine their individual anaerobic...
To improve performance in endurance sports, it is important to include both high-intensity and low-intensity training, but there neither a universally accepted practice nor clear scientific evidence that allows reliable statements about the predominance of specific training method. This randomized controlled trial compared effects polarized model (POL) (LIT) on physiological parameters mountain bike cross-country Olympic (XCO) race eighteen competitive XCO athletes (17.9 ± 3.6 years). The...
Although running is a common leisure activity and core training regiment for several athletes, between 29% 79% of runners sustain an overuse injury each year. These injuries are linked to excessive fatigue, which alters how someone runs. In this work, we explore the feasibility modelling Borg received perception exertion (RPE) scale (range: [6]–[19] [20]), well-validated subjective measure using audio data captured in realistic outdoor environments via smartphones attached runners' arms....
Objectives Traditional performance tests in mountain bike marathon (XCM) primarily quantify aerobic metabolism and may not describe the relevant capacities XCM. We aimed to validate a comprehensive test protocol quantifying its intermittent demands. Methods Forty-nine athletes (38.8±9.1 years; 38 male; 11 female) performed laboratory test, including an incremental determine individual anaerobic threshold (IAT), peak power output (PPO) three maximal efforts (10 s all-out sprint, 1 min effort...
Abstract Mountain bike Cross-Country Olympic (XCO) has an intermittent performance profile, underlining the importance of anaerobic metabolism. Traditional tests in cycling primarily quantify aerobic metabolism and inadequately meet demands XCO. The aim was therefore to validate a specific test that quantifies these requirements by means XCO race. Twenty-three competitive athletes (17.9±3.6 years) performed previously developed race within one week. Correlations between individual threshold...

Abstract Individuals with depression often engage in iterative “rumination” about challenging situations and potential outcomes. Although the state of rumination has been associated diverse univariate neurophysiological features, to use multivariate patterns decode it remains uncertain. In this study, we trained linear support vector machines differentiate from distraction using alpha, beta, theta bands, as well inter-channel connectivity. We used validated tasks induce or for eight minutes...
One key feature of depressive disorders is rumination, which associated with the onset, duration, and severity disorder. Moderate-intensity exercise (ME) has been established as treatment for depression. The “distraction hypothesis” assumes that ameliorates depression because it distracts individuals from ruminative thoughts. We investigated whether a single bout ME reduces self-reported shifts individuals’ mental state rumination to distraction, temporal dynamics these effects. Participants...
Despite the many positive effects of sports, it also carries risk overuse injuries if done excessively. Early detection a runner's exertion is therefore highly relevant for preventing and increasing well-being individuals. Recent machine learning methods have given little to no attention impact individual characteristics such as age or sex on recognition. We tackle this issue by proposing personalised system. To achieve this, we first train model using transfer approach with shared common...
