A pilot study: session-RPE method for quantifying training load in judo athletes
This study aimed to verify the relationship between perceived exertion (session-RPE) and heart rate (HR) methods when quantifying internal training loads in different judo training sessions. Nine male judo athletes performed two training sessions lasting 60  min with a 48 h interval between them: (1)randori and (2) technical –tactical. The internal training load was quantified through the session-RPE (CR 0–10) and the HR methods, as suggested elsewhere (Banister’s and Edwards methods). The Pearson’s linear correlation was used to verify the relationship between session-RPE and HR methods (p

The effect of endurance exercise and methadone on μ-opioid receptor gene expression in morphine-dependent rats following withdrawal syndrome
AbstractBackgroundOpiate dependence (e.g., morphine) is one of the most important problems affecting human health. Morphine reduces the irritability of neurons in the pain pathway by attaching to some such opioid receptors such as μ receptor (MOR). Exercise can improve destructions due to opiate dependence in many of the body organs including nerve systems. Thus, the aim of this study was to investigate the effect of endurance exercise training (8 weeks of moderate exercise) and methadone on μ-opioid receptor gene (OPRM1) expression in morphine-dependent rats following withdrawal syndrome.Methods48 male Wistar r...

An fMRI study on runner ’s high and exercise-induced hypoalgesia after a 2-h-run in trained non-elite male athletes
AbstractWhile elite long-distance runners experience hypoalgesia and sometimes runner ’s high after running, these phenomena are rarely explored in non-elite runners. Therefore, we examined the effect of a 2-h-run on mood and pain processing in 15 non-elite male runners using repeated painful and nonpainful pinprick stimulation and functional magnetic resonance imaging (fMRI). Pain ratings, pressure pain stimulus responses, and euphoria ratings were assessed immediately after a 2-h-run and at a run-free control day (RFC). Analysis of a half-standardized-interview indicates an improvement of mood. However, there was n...

AbstractAlpha-actinin-3 (ACTN3) gene is one of the most extensively investigated genes associated with human physical performance. TheACTN3 gene viaACTN3 R/X gene polymorphism codes the ACTN3 protein proteins that are localized at the boundaries of sarcomeres in the contractile apparatus of muscle Z disk. TheACTN3 R allele codes for functioningACTN3 gene that results in the production of ACTN3 protein, while incomplete sequence in theACTN3 X allele, preventing the production of that protein.

High-intensity interval training prevents cognitive-motor impairment and serum BDNF level reduction in parkinson mice model
AbstractParkinson ’s disease (PD) is a neurodegenerative disease characterized by a progressive degeneration of dopaminergic neurons in the substantia nigra pars compact (SNpc). Previous studies have shown that cognitive deficits and motor impairment symptoms seen in PD and that physical exercise may exert benefici al effects on PD. In most cases, brain-derived neurotrophic factor (BDNF) is involved in such effects. However, little is known on the role of BDNF in exercise, especially high-intensity interval training (HIIT)-related effects on PD.
