The studies in the literature have not sufficiently investigated the effects of core stabilization training on anaerobic performance. Therefore, this study was planned to comparatively investigate effects of progressive core stabilization training applied to elite athletes on anaerobic capacity, anaerobic performance, and fatigue.
During an incremental cardiopulmonary exercise test (CPET) performed with a ramp protocol, it is very important to determine the anaerobic threshold, defined as the point at which the metabolism switches from being predominantly aerobic to also being anaerobic. The anaerobic threshold can be determined invasively, by identifying the increase in blood lactates with an arterial sampling, or, more commonly, non-invasively by three methods: the V-slope method, the ventilatory equivalents method and by using end-expiratory oxygen and carbon dioxide pressure (PETO2 and PETCO2 respectively). Normally, the anaerobic threshold is determined by the first method and the other two are used to confirm the value. The finding of different anaerobic threshold values using these three methods has been reported anecdotally in the past, while a prevalence of 11% in a healthy population has recently been described. Regular training, particularly that aimed at endurance sports, is able to shift the anaerobic threshold to higher exercise intensities. At present, the physiological reasons for the presence of a double threshold are unclear. The aim of the study is to identify the anaerobic threshold by means of the V-slope method and by means of the ventilatory equivalents method in athletes who have performed an incremental ramp CPET at the laboratories of the investigating centres, to assess in how many athletes a double threshold is present and to try to interpret the physiological/ pathophysiological significance of this finding. In this retrospective and prospective observational study, healthy male and female athletes who have had a cardiopulmonary test at our laboratories from 2007 to the present (retrospectively recruited) and prospectively recruited until the calculated sample size is reached will be enrolled.
A randomized, controlled trial to evaluate the effects of two versions of 10 high intensity interval trainings (HIIT) within a 7-day shock microcycle on endurance performance, well-being, health, stress and recovery in trained athletes.
The researcher aimed to investigate the effects of oculo-motor exercises on dynamic visual acuity, balance and performance of volleyball players whose performance can be improved with visual skills training. H0: Oculo-motor exercises applied to volleyball players are effective on dynamic visual acuity, balance and performance. H1: Oculo-motor exercises have no effect on dynamic visual acuity, balance and performance in volleyball players.
The main objective of this research was to carry out an experimental study, triple blind, on the possible immunophysiological effects of a nutritional supplement (Synbiotic, Gasteel Plus®, Heel España S.A.U.), containing a mixture of probiotic strains, such as Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, Bifidobacterium longum ES1, as well as prebi-otic fructooligosaccharides, in both professional athletes and sedentary people. The effects on some inflammatory/immune (IL-1β, IL-10, and immunoglobulin A) and stress (epinephrine, nore-pinephrine, dopamine, serotonin, CRH, ACTH, and cortisol) biomarkers were evaluated, determined by flow cytometer and ELISA. The effects on metabolic profile and physical activity, as well as on various parameters that could affect physical and mental health, were also evaluated via the use of accelerometry and validated questionnaires.
The gastrointestinal tract contains hundreds of millions of microorganisms, collectively called the intestinal flora, which plays an important role in the health of the host. Many studies have also confirmed that the composition and function of the intestinal flora can be changed through the training chain. Changes in the composition of intestinal microbes can affect exercise performance, energy metabolism, oxidative stress, immune function, inflammation, and tissue repair. Therefore, maintaining a healthy gut microbial balance is essential for athletes' health, training, nutritional status, and athletic performance. This project intends to use metagenomics, proteomics, and metabolomics and other technologies to systematically explore the effects of different training periods and dietary interventions on the intestinal flora of muscle strength and endurance athletes. , Protein expression and the influence of metabolites. In the plan, explore the differences in the intestinal flora between muscle strength and endurance sports athletes during the preparation period, competition period, and transition period, and collect blood and feces to perform protein and metabolite molecular changes. It is hoped that through the smooth implementation of this research project, the research results can be applied to personalized diet planning, improve intestinal adaptability and the effectiveness of sports nutrition intervention, and then adjust athletes' status and improve sports performance to win the highest honor for the country in the arena.
It is becoming increasingly evident that sleep plays an essential role for human health, and it represents an important biophysiological variable for athletes' well-being and recovery. The International Olympic Committee recently highlighted the importance of obtaining sufficient sleep volume and quality among athletes, but acute sleep deprivation is not unusual. Several factors, both endogenous and exogenous, are able to negatively influence sleep in athletes: body temperature, altitude, chronotype, training volume, anxiety, westward and eastward travels, and many others. Since December 2019, when a new coronavirus (SARS-CoV-2) was originally revealed by an ophthalmologist in Wuhan (Hubei province, China), a related severe acute respiratory syndrome - namely COVID-19 - has been spreading at a pandemic rate, putting global health systems under unprecedent pressure. Italy, as the first Western country tremendously hit by this disease outbreak, has become the iconic resilient outpost under international policymakers' attention. When initial clusters were identified, restrictive actions to curb isolated upsurges of infection were taken by the health region system of Lombardy, thereafter, were extended to all northern Italy and to the entire country. From February 21, when the first Italian COVID-19 case was diagnosed in southern Lombardy, to March 22, when Italian's government restrictions to contain the pandemic were extended, prohibiting all non-essential business activities and banning all movements of people nationwide, the country faced an unchartered scenario, from several standpoints, along with the psychosocial one. Inevitably, the Covid-19 outbreak has largely influenced the daily life of athletes too. Therefore, the primary aim of this study was to examine the differences in athletes' sleep quality, quantity and training volumes during the social confinement due to the virus outbreak. For this purpose, a survey will be used. This variables will be evaluated in 3 different time frames: 1) May 2020; 2) September 2020; 3) January 2021.
In this study, the investigator aims to measure stress, anxiety, mood, life satisfaction measures among elite athletes during COVID-19 and measure the relationship between these measures and the changes in training characteristics in elite athletes during the COVID-19 pandemic.
Monitoring individual responses to training is an important key factor to prescribe to most effective training programs. Heart-rate variability (HRV) could be used for monitoring the training status of endurance athletes in order to detect the fatigue status and to assess the adaptation to training. This direct fatigue measuring method has been little used to prescribe or regulate exercise prescription. Moreover, it allows new possibilities for the training load prescription according to an athlete's status, the response to the training load, and the adaptation to training. Regardless HRV-guided training, the athlete performance could also be influenced by precompetitive mood and anxiety, which can also be reflected in the precompetitive HRV scores and the subjective effort perception.
