Adaptation of The New Normal Sports Training Centering System

The COVID-19 pandemic has resulted in the temporary suspension of the training centering system which has resulted in complex decisions relating to the continuation of training activities in accordance with existing circumstances. This paper aims to provide education and guidance in the implementation of regular exercise programs that must be realized as a solution to minimize the occurrence of COVID-19 transmission in the regular training process as well as provide understanding to the main sports branch management, coaches and athletes in carrying out regular training programs. This study uses a literature review method where the researcher conducts a series of studies by reviewing and analyzing various content and data, which involves various kinds of information related to the implementation of the training centering system in the new normal era. There are 4 key principles in the re-implementation of the training process on a regular basis or training camps, including preparation for resumption of training, criteria for training commencement, assessments and guidelines that serve as a reference for the implementation of training camps, as well as management and strategies for mitigating COVID-19 risks at training camps.

Microcirculatory and Metabolic Responses during Voluntary Cycle Ergometer Exercise with a Whole-Body Neuromuscular Electrical Stimulation Device

Vigorous exercise increases blood viscosity and may pose a risk of cardiovascular events in patients with cardiovascular diseases. We recently reported that single-use of novel whole-body neuromuscular electrical stimulation (WB-NMES) can be safely applied in healthy subjects without adversely affecting blood fluidity. We performed a crossover study to explore the effectiveness and safety of a hybrid exercise with ergo-bicycle and WB-NMES; 15 healthy volunteers, aged 23–41 years, participated in this study. No arrhythmias were detected during the hybrid exercise and 20 min recovery, and although blood fluidity was transiently exacerbated immediately after both the exercise programs, in vivo parameters in the sublingual and nailfold microcirculation remained unchanged. There was a significant decrease in blood glucose and increase in lactic acid levels immediately after both exercise programs. Even with the same workload as the cycle ergometer exercise, the oxygen intake during the hybrid exercise remained higher than that during the cycle ergometer exercise alone (p < 0.05, r = 0.79, power = 0.81). Both the hybrid and voluntary cycle ergometer exercises transiently exacerbated blood fluidity ex vivo; however, microvascular flow was not adversely affected in vivo.

The Physical Condition of Deaf Primary School-Age Children and How to Correct it Using Physical Education Methods

The latest studies have shown that the parameters of physical development of children with hearing loss are attracting the attention of the scientific community. However, there are few studies that investigate changes in the physical condition of deaf children after improving physical education. The purpose of this work is to study the physical condition of deaf primary school-age children and develop a corrective program using methods of physical education. The study included 72 deaf children (to the experimental nEG=37 and the control group nCG=35) and 28 primary school-age children with normal hearing. The choice of research sample was random and the age of the children ranged from 6-10 years old. The physical condition of the schoolchildren was determined using a set of medical and biological methods: blood pressure measurement, heart rate calculation according to the electrocardiogram R-R interval, spirometry, electrocardiography, echocardiography, physical work capacity (PWC150) test, measurement of catecholamines using E. Matlina’s method, and anthropometry. The experimental physical education program consisted of a set of physical, breathing and posture exercises as well as physical games. Games were divided by complexity, level of perception, physical intensity, and impact on the body. It was determined that deafness negatively affects anthropometric indicators, the respiratory system, and the functional condition of the sympathoadrenal system, but does not affect the morpho-functional values of cardiac performance in primary school-age children. The study proves the effectiveness of adopting exercise programs based on physical games as a means of correcting the physical condition of deaf children. The study confirmed that the implementation of exercise programs for the correction of the physical condition of deaf primary school-age children by means of physical education based on physical games in the daily routine of special boarding schools has a positive effect on the children’s respiratory, cardiovascular and sympathoadrenal systems.

The Potential Role of Previous Physical Exercise Program to Reduce Seizure Susceptibility: A Systematic Review and Meta-Analysis of Animal Studies

Background: Clinical and pre-clinical studies indicate a reduction in seizure frequency as well as a decrease in susceptibility to subsequently evoked seizures after physical exercise programs. In contrast to the influence of exercise after epilepsy previously established, various studies have been conducted attempting to investigate whether physical activity reduces brain susceptibility to seizures or prevents epilepsy. We report a systematic review and meta-analysis of different animal models that addressed the impact of previous physical exercise programs to reduce seizure susceptibility.Methods: We included animal model (rats and mice) studies before brain insult that reported physical exercise programs compared with other interventions (sham, control, or naïve). We excluded studies that investigated animal models after brain insult, associated with supplement nutrition or drugs, that did not address epilepsy or seizure susceptibility, ex vivo studies, in vitro studies, studies in humans, or in silico studies. Electronic searches were performed in the MEDLINE (PubMed), Web of Science (WOS), Scopus, PsycINFO, Scientific Electronic Library Online (SciELO) databases, and gray literature, without restrictions to the year or language of publication. We used SYRCLE's risk of bias tool and CAMARADES checklist for study quality. We performed a synthesis of results for different types of exercise and susceptibility to seizures by random-effects meta-analysis.Results: Fifteen studies were included in the final analysis (543 animals), 13 of them used male animals, and Wistar rats were the most commonly studied species used in the studies (355 animals). The chemoconvulsants used in the selected studies were pentylenetetrazol, penicillin, kainic acid, pilocarpine, and homocysteine. We assessed the impact of study design characteristics and the reporting of mitigations to reduce the risk of bias. We calculated a standardized mean difference effect size for each comparison and performed a random-effects meta-analysis. The meta-analysis included behavioral analysis (latency to seizure onset, n = 6 and intensity of motor signals, n = 3) and electrophysiological analysis (spikes/min, n = 4, and amplitude, n = 6). The overall effect size observed in physical exercise compared to controls for latency to seizure onset was −130.98 [95% CI: −203.47, −58.49] (seconds) and the intensity of motor signals was −0.40 [95% CI: −1.19, 0.40] (on a scale from 0 to 5). The largest effects were observed in electrophysiological analysis for spikes/min with −26.96 [95% CI: −39.56, −14.36], and for spike amplitude (μV) with −282.64 [95% CI: −466.81, −98.47].Discussion:Limitations of evidence. A higher number of animal models should be employed for analyzing the influence of exerciseon seizure susceptibility. The high heterogeneity in our meta-analysis is attributable to various factors, including the number of animals used in each study and the limited number of similar studies. Interpretation. Studies selected in this systematic review and meta-analysis suggest that previous physical exercise programs can reduce some of the main features related to seizure susceptibility [latency seizure onset, spikes/min, and spike amplitude (μV)] induced by the administration of different chemoconvulsants.Systematic Review Registration: PROSPERO, identifier CRD42021251949; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=251949.
