EEG differences in competitive female gymnastics, soccer, and esports athletes between resting states with eyes closed and open.

Athletes heavily rely on visual perception for performance. This study delves into electroencephalographic (EEG) brain activity among gymnastics, soccer, and esports athletes during resting states with eyes closed (REC) and open (REO) and compares differences in EEG alpha power from REC to REO (∆ EC-EO ) across athlete groups. Forty-two female participants, including 14 from each athletic discipline, underwent two 5-minute EEG recordings, first during REC and then during REO conditions.

Recovery Effects of Foam Rolling on Psychophysiological Responses in Thai National Male Ice Hockey Players.

We examined the short-term effects of foam rolling (FR), dynamic stretching (DS), and passive rest (PR) following simulated ice hockey exercise (IHE) on heart rate (HR), blood lactate (BL), leg choice reaction time (CRT), rating of perceived exertion (RPE), and global rating of change (GRC) in elite ice hockey players. The study followed a randomized cross-over design. Fifteen national male ice hockey players were assigned to the FR, DS, or PR interventions for 10 mins following 35- min of simulated IHE.

A Home-Based Exercise Program With Active Video Games for Balance, Motor Proficiency, Foot and Ankle Ability, and Intrinsic Motivation in Children With Chronic Ankle Instability: Feasibility Randomized Controlled Trial.

Objective: The purpose of this study was to investigate the feasibility of a 4-week home-based exercise training program using active video games (AVGs) for balance, motor proficiency, foot and ankle ability, and intrinsic motivation in children with CAI.

A low- dose of caffeine suppresses EEG alpha power and improves working memory in healthy University males.

The effects of a low dose of caffeine, administered in the morning, on brain wave activity and cognitive function were investigated in 25 healthy university Southeast Asian men (mean age ±standard deviation: 21 ± 2 years). Participants received a placebo (PLA) or a 50 mg caffeinated drink (CAF) under randomized, double-blind crossover conditions, with 1 week between conditions. Brain wave activity was assessed using electroencephalography (EEG) from a 5 min eyes-closed resting state.

The Effects of Constraining Head Rotation on Eye and Whole-Body Coordination During Standing Turns at Different Speeds.

A limitation of the ability to rotate the head with respect to the upper body has been associated with turning problems; however, the extent of head constraints on whole-body coordination has not been fully determined. The aim of this study was to limit head on body rotation and observe the effects on whole-body coordination during standing turns at various speeds. Twelve participants completed standing turns at 180°.

Benefits of task-specific movement program on en bloc turning in Parkinson's disease: A randomized controlled trial.

Introduction: En bloc turning highlights a lack of rotational intersegmental coordination, which commonly impacts turning ability in people with Parkinson's disease (PD). Whilst this turning deficit responds fairly well to medical treatment, it may be further mitigated by performing specific exercise training. Thus, the present study aimed to examine the effects of a 4-week exercise program, which focused on task-specific movements (TSM program) on turning ability and clinical outcomes in people with PD.

Body composition and physical fitness improve after 8 weeks of high-intensity circuit training using body weight in obese women.

Background: We examined the effects of an 8-week modified high-intensity circuit training using body weight as resistance (HICT) on health-related physical fitness in sedentary obese women.

Methods: Twenty-four sedentary obese women were allocated into the HICT or a non-training control group (CG). The modified HICT was performed for eight weeks (three times per week).

Benefits of Thai Yoga on physical mobility and lower limb muscle strength in overweight/obese older women: A randomized controlled pilot trial.

Background And Purpose: Although Thai Yoga (TY) is reported to improve health-related fitness for the elderly, no study has yet carried out the effect of TY Program on physical mobility and lower-limb muscle strength in overweight/obese older women.

Materials And Methods: In a randomized controlled pilot design, twenty-two sedentary women with a BMI ≥ 23 kg/m, aged 62 ± 1 years were randomly assigned to either a TY group for 60 min, 3 times a week or to a "no exercise" control (CON) group. Sit and reach (SRT), functional reach (FRT) and 30-s chair stand (CST-30), 8-foot up and go (8UGT), 6-min walk (6MWT)) and lower-limb muscle strength were measured at the beginning, 4, and 8 weeks.

Effects of a 20-min Nap after Sleep Deprivation on Brain Activity and Soccer Performance.

We examined effects of a 20-min nap following 3 h of sleep deprivation on brain wave activity, auditory reaction time, the running-based anaerobic sprint test, leg muscle strength and the rating of perceived exertion in male college soccer players. Eleven players underwent three sleep conditions; normal sleep, sleep deprivation and 20-min nap after sleep deprivation. The sleep deprivation demonstrated an increase in the mean power of delta waves over the frontal area and a decrease in the mean power of alpha waves over the parietal area compared to the normal sleep.

Can We Accurately Measure Axial Segment Coordination during Turning Using Inertial Measurement Units (IMUs)?

Camera-based 3D motion analysis systems are considered to be the gold standard for movement analysis. However, using such equipment in a clinical setting is prohibitive due to the expense and time-consuming nature of data collection and analysis. Therefore, Inertial Measurement Units (IMUs) have been suggested as an alternative to measure movement in clinical settings.

ZIP8 expression in human proximal tubule cells, human urothelial cells transformed by Cd+2 and As+3 and in specimens of normal human urothelium and urothelial cancer.

Background: ZIP8 functions endogenously as a Zn+2/HCO3- symporter that can also bring cadmium (Cd+2) into the cell. It has also been proposed that ZIP8 participates in Cd-induced testicular necrosis and renal disease. In this study real-time PCR, western analysis, immunostaining and fluorescent localization were used to define the expression of ZIP8 in human kidney, cultured human proximal tubule (HPT) cells, normal and malignant human urothelium and Cd+2 and arsenite (As+3) transformed urothelial cells.

Differences in the epigenetic regulation of MT-3 gene expression between parental and Cd+2 or As+3 transformed human urothelial cells.

Background: Studies have shown that metallothionein 3 (MT-3) is not expressed in normal urothelium or in the UROtsa cell line, but is expressed in urothelial cancer and in tumors generated from the UROtsa cells that have been transformed by cadmium (Cd+2) or arsenite (As+3).The present study had two major goals. One, to determine if epigenetic modifications control urothelial MT-3 gene expression and if regulation is altered by malignant transformation by Cd+2 or As+3.

Zinc rescues dopaminergic SK-N-SH cell lines from methamphetamine-induced toxicity.

Methamphetamine (METH) is a potent inducer of dopamine (DA) release, and is toxic to DA neurons. It has been reported that the formation of free radicals is an early signaling event that mediates cell death caused by METH. Currently, studies suggest that the generation of free radicals by oxidative catabolism of DA and dysfunction of the mitochondrial respiration chain are important mediators of neuronal death in Parkinson's disease (PD) and one process may counter the effect of the other.

Zinc protects SK-N-SH cells from methamphetamine-induced alpha-synuclein expression.

Methamphetamine (METH) is a well-known drug of abuse and neurotoxin that may cause temporary or permanent disturbances in the dopaminergic systems of the brain, predisposing individuals to Parkinsonism. Previously, we have shown that METH causes dopaminergic cell death by increasing the production of reactive oxygen species (ROS) and by depleting cellular ATP levels. These effects were abolished by pretreatment with ZnCl(2) which enhanced expression of the zinc binding protein, metallothionein.

Metallothionein provides zinc-mediated protective effects against methamphetamine toxicity in SK-N-SH cells.

Methamphetamine (METH) is a drug of abuse and neurotoxin that induces Parkinson's-like pathology after chronic usage by targeting dopaminergic neurons. Elucidation of the intracellular mechanisms that underlie METH-induced dopaminergic neuron toxicity may help in understanding the mechanism by which neurons die in Parkinson's disease. In the present study, we examined the role of reactive oxygen species (ROS) in the METH-induced death of human dopaminergic SK-N-SH cells and further assessed the neuroprotective effects of zinc and metallothionein (MT) against METH-induced toxicity in culture.

Melatonin exerts its analgesic actions not by binding to opioid receptor subtypes but by increasing the release of beta-endorphin an endogenous opioid.

The occurrence of systematic diurnal variations in pain thresholds has been demonstrated in human. Salivary melatonin levels change following acute pain when other factors that could explain the change have been removed or controlled. Melatonin-induced analgesia is blocked by naloxone or pinealectomy.
