An expanded repertoire of intensity-dependent exercise-responsive plasma proteins tied to loci of human disease risk.

ABSTRACT: Routine endurance exercise confers numerous health benefits, and high intensity exercise may accelerate and magnify many of these benefits. To date, explanatory molecular mechanisms and the influence of exercise intensity remain poorly understood. Circulating factors are hypothesized to transduce some of the systemic effects of exercise. We sought to examine the role of exercise and exercise intensity on the human plasma proteome. We employed an aptamer-based method to examine 1,305 plasma proteins in 12 participants before and after exercise at two physiologically defined intensities (moderate and high) to determine the proteomic response. We demonstrate that the human plasma proteome is responsive to acute exercise in an intensity-dependent manner with enrichment analysis suggesting functional biological differences between the moderate and high intensity doses. Through integration of available genetic data, we estimate the effects of acute exercise on exercise-associated traits and find proteomic responses that may contribute to observed clinical effects on coronary artery disease and blood pressure regulation. In sum, we provide supportive evidence that moderate and high intensity exercise elicit different signaling responses, that exercise may act in part non-cell autonomously through circulating plasma proteins, and that plasma protein dynamics can simulate some the beneficial and adverse effects of acute exercise.

Project description:Numerous studies suggest beneficial effects of aerobic exercise at moderate intensity on cognition, while the effects of high-intensity exercise are less clear. This study investigated the acute effects of exercise at moderate and high intensities on executive functions in healthy adults, including functional MRI to examine the underlying neural mechanisms. Furthermore, the association between exercise effects and cardiorespiratory fitness was examined. 64 participants performed in two executive function tasks (flanker and Go/No-go tasks), while functional MR images were collected, following two conditions: in the exercise condition, they cycled on an ergometer at either moderate or high intensity (each n = 32); in the control condition, they watched a movie. Differences in behavioral performance and brain activation between the two conditions were compared between groups. Further, correlations between cardiorespiratory fitness and exercise effects on neural and behavioral correlates of executive performance were calculated. Moderate exercise compared to high-intensity exercise was associated with a tendency towards improved behavioral performance (sensitivity index d') in the Go/No-go task and increased brain activation during hit trials in areas related to executive function, attention, and motor processes (insula, superior frontal gyrus, precentral gyrus, and supplementary motor area). Exercise at high intensity was associated with decreased brain activation in those areas and no changes in behavioral performance. Exercise had no effect on brain activation in the flanker task, but an explorative analysis revealed that reaction times improved after high-intensity exercise. Higher cardiorespiratory fitness was correlated with increased brain activation after moderate exercise and decreased brain activation after high-intensity exercise. These data show that exercise at moderate vs. high intensity has different effects on executive task performance and related brain activation changes as measured by fMRI and that cardiorespiratory fitness might be a moderating factor of acute exercise effects. Thus, our results may contribute to further clarify the neurophysiological mechanisms underlying the beneficial effects of exercise on cognition.

Project description:<p>Thoroughbred (TB) racehorses are subjected to rigorous conditioning programs involving exercise sessions of various types, distances and intensities. These programs aim to optimize both their physical and mental capabilities, which are essential to achieve maximal performance. Conventional investigations of exercise-induced metabolic responses typically focus on a limited set of targeted hematological and biochemical parameters. This field study was conducted to comprehensively assess the metabolic responses triggered by exercise sessions routinely used in TB conditioning. To accomplish this, we employed an untargeted metabolomics approach. Blood samples were collected from 10 racehorses at rest and after completing a routine exercise session. The population was subsequently divided into two groups based on the intensity of the exercise performed: a high-intensity group (n = 6, gallop at ± 13.38 m/s, 1400 m) and a moderate-intensity group (n = 4, soft canter at ± 7.63 m/s, 2500 m). The exercise intensity was evaluated through monitoring of speed, heart rate, and targeted hematological and biochemical parameters (e.g., lactatemia, hematocrit, etc). Resting and 30 min post-exercise plasma samples were analyzed using an untargeted metabolomics approach based on ultra-performance liquid chromatography coupled with high-resolution mass spectrometry. Unsupervised principal component analysis revealed changes in the metabolome from pre- to post-exercise samples with greater alterations following high-intensity exercise. 54 metabolites, mainly related to amino acid, fatty acid, nucleic acid and vitamin metabolism, were altered following high-intensity exercise versus 23 metabolites, mainly related to fatty acid and amino acid metabolism, following moderate-intensity exercise. Untargeted metabolomics complemented the routine biochemical analyses, allowing a more comprehensive exploration of the exercise-induced response to exercises used in routine conditioning. As previously reported by traditional biochemistry, exercise-induced changes in energy metabolism in TB racehorses have been confirmed. Through metabolomics, the involvement of lipid and amino acid metabolism during routine exercise and recovery has been highlighted, aspects that had previously been largely overlooked in Thoroughbred racehorses.</p>
