Abstract
Objective: To compare the effects of intensity-matched acute exercise at different intensities on proinflammatory and anti-inflammatory cytokines between able-bodied (AB) and spinal cord injured (SCI) individuals.Design: Non-Randomized Controlled Trial.Setting: Community settings in São Paulo - Brazil.Participants: Eight AB and nine SCI paraplegic.Interventions: Participants underwent three exercise sessions at different relative intensities: at ventilatory threshold 1 intensity (VT1), 15% below VT1, and 15% above VT1. Similar energy expenditures were established from exercises with different intensities for each volunteer. The AB group was tested on a conventional treadmill, whereas the SCI group was tested on a treadmill adapted for wheelchair use. Blood samples were collected at baseline, immediately after, and 30 min after the exercise sessions.Outcome measures: Interleukin 1 receptor antagonist, interleukin 1 beta, interleukin 2, interleukin 4, interleukin 6, interleukin 10 and tumoral necrosis factor alpha were measured.Results: When groups were compared, interleukin - 2 was found higher, whereas interleukin - 4 and interleukin - 10 were found lower in the SCI group at all collection times in the three exercise intensities (all P < 0.05). Interleukin - 1 receptor antagonist was found higher immediately after exercise at VT1, 15% above VT1 and 30 min after 15% below VT1 in the AB group (all P < 0.05). In the AB group, an increase in interleukin - 6 immediately after the exercise at VT1 compared with baseline was found (P = 0.01).Conclusion: Individuals with SCI may have to perform physical exercise at a higher volume or energy expenditure than AB individuals to obtain similar anti-inflammatory benefits of acute exercise.Trial registration: Uniform Trial Number identifier: U1111-1232-8142.

Ramires Lima K, de Souza da Rosa AC, Severo Picua S, Souza E Silva S, Marks Soares N, Billig Mello-Carpes P. One single physical exercise session improves memory persistence by hippocampal activation of D1 dopamine receptors and PKA signaling in rats. Brain Res 2021; 1762:147439.

Abstract
Previously, we demonstrated that one single physical exercise session could positively modulate recognition memory persistence by D1/D5 activation. Here, we aim to investigate whether the effect of physical exercise on memory occurs due to the activation of both receptors, D1 and D5, or only one of them. Adult male Wistar rats were habituated on a treadmill one week before experiments. After learning session in the object recognition task, some animals received intrahippocampal infusions of the vehicle or a D1/D5 agonist (SKF 38393, 12.5 μg/μL/side), whereas others performed a single session of physical exercise on a treadmill (30 min at an intensity of 60-70% of indirect VO2 max.). Immediately after physical exercise, some animals received intrahippocampal infusions of vehicle or D1/D5 antagonist (SCH 23390, 1 μg/μL/side). Signaling pathways of D1 and D5 receptors in the hippocampus were evaluated by pharmacological activation or inactivation of protein kinases A (PKA) and C (PKC), respectively. According to previous findings, D1/D5 agonist and a single physical exercise session after learning promoted memory persistence, and D1/D5 block impaired physical exercise effect. Importantly, here we demonstrated for the first time that PKA inhibition, but not PKC, impairs the effect of acute physical exercise on memory persistence. Besides, PKA stimulation can promote its effects on memory. Therefore, we provide evidence that corroborates the idea that D1-like dopaminergic receptors, by activation of the PKA pathway, are involved in the effects of acute physical exercise on memory.

Abstract
Previously we demonstrated that a single physical exercise session promotes the persistence of object recognition (OR) memory and this effect involves the activation of the noradrenergic system. Here, using adult male Wistar rats (3 months old) we confirm that an aerobic single physical exercise session (30 min of treadmill running at an intensity of 60-70 % of indirect VO2 max.) after OR learning promotes memory persistence. We also demonstrate that this effect involves the dopaminergic system, since it is blocked when a D1-family receptor antagonist (SCH-23390, 1μg/μl) is infused into the hippocampus after the physical exercise session. Additionally, through HPLC experiments we demonstrate that a physical exercise session increases the hippocampal dopamine levels. Taken together, our results demonstrate that acute post-learning physical exercise is able to promote the persistence of OR memory, inducing the release of dopamine in hippocampus, which is necessary for the modulation of memory persistence. This work brings new evidences on the benefit of a single physical exercise session to memory, as well as suggests that catecholaminergic mechanisms are behind this effect.

Abstract
Background Many researchers have considered the impact of physical exercise on perceptual-cognitive performance. There have also been a substantial number of studies that have examined how perceptual-cognitive skills differ between elite athletes and non-athletes. However, the knowledge on how physical exercise interacts with perceptual-cognitive skill is limited. This systematic review aims to provide detailed information on how athletes’ perceptual-cognitive performance is influenced by acute physical exercise load and whether these effects differ between elite athletes and lesser skilled groups. Methods A systematic review was conducted using different combinations of the keywords physical load, acute, exercise, perception, cognition, perceptual, cognitive, sport, and athlete with the PubMed and SportDiscus databases. Additional articles were found through screening the references of these papers. Articles had to (a) be full journal articles written in English, (b) include an athlete sample, (c) examine acute effects of physical exercise, and (d) measure a perceptual-cognitive task as the dependent variable. Results Twenty-six articles matched the inclusion criteria. Results suggested the impact of acute physical exercise on perceptual-cognitive performances of athletes depends on the specificity of the induced exercise and perceptual-cognitive task. Additionally, speed and accuracy were influenced differently by physical exercise. Furthermore, skilled athletes seem to be more positively influenced by acute physical exercise than novices. Conclusion Since many factors influence perceptual-cognitive expertise, future research should be highly precise (e.g., regarding the definition of variables, the intensity of the physical exercise) and specific (e.g., regarding the tasks used, the type of the physical exercise).

Abstract
Background Oxidative stress and inflammation are common findings in chronic kidney disease (CKD) patients, and they are directly related to the increased risk of developing cardiovascular disease, which is the major cause of death in these patients, particularly for those undergoing hemodialysis (HD). Strength physical exercise is a new therapeutic approach to reduce these complications in CKD patients. Following this, the purpose of this study was to assess the effect of acute intradialytic strength physical exercise on oxidative stress and inflammatory responses in HD patients. Methods Sixteen HD patients were studied (11 women; 44.4±14.6 years; body mass index 23.3±4.9 kg/m2; 61.6±43.1 months of dialysis) and served as their own controls. Acute (single session) intradialytic physical exercise were performed at 60% of the one-repetition maximum test for three sets of 10 repetitions for four exercise categories in both lower limbs during 30 minutes. Blood samples were collected on two different days at exactly the same time (30 minutes and 60 minutes after initiating the dialysis—with and without exercise). Antioxidant enzymes activity [superoxide dismutase (SOD), catalase, and glutathione peroxidase], lipid peroxidation marker levels (malondialdehyde), and inflammatory marker levels (high-sensitivity C-reactive protein) were determined. Results SOD plasma levels were significantly reduced after acute physical exercise from 244.8±40.7 U/mL to 222.4±28.9 U/mL (P=0.03) and, by contrast, increased on the day without exercise (218.2±26.5 U/mL to 239.4±38.6 U/mL, P=0.02). There was no alteration in plasma catalase, glutathione peroxidase, malondialdehyde, or high-sensitivity C-reactive protein levels in on either day (with or without exercise). Additionally, there was no association between these markers and clinical, anthropometric, or biochemical parameters. Conclusion These data suggest that acute intradialytic strength physical exercise was unable to reduce oxidative stress and inflammation, and in addition, it seems to reduce plasma SOD levels, which could exacerbate the oxidative stress in HD patients.

Abstract
The dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) concentrations during acute and chronic exercise (training) have been investigated only fairly recently. DHEA is generally preferred to DHEA-S for exploring the acute exercise repercussions in laboratory or field tests because of its shorter elimination half-life. Conversely, DHEA-S is preferred to estimate chronic adaptations. Both can be measured noninvasively in saliva, and it is therefore possible to follow these hormone responses in elite athletes during competitive events and in healthy and pathological populations, without imposing additional stress. Indeed, the correlation between saliva and serum concentrations is high for steroid hormones, both at rest and during exercise. In this review, we will first summarize the current knowledge on the DHEA/DHEA-S responses to exercise and examine the potential modulating factors: exercise intensity, gender, age, and training. We will then discuss the ergogenic effects that athletes expect from the exogenous administration of DHEA and the antidoping methods of analysis currently used to detect this abuse.
