E-Sports, which attract great attention in the media and social networks, brings health problems and some risks, depending on the attractiveness of games and the time spent in the digital world. When the investigators examine the literature, although different studies are showing that E-Athletes experience pain and sleep problems, no study examines the factors related to pain and sleep quality together. Therefore, our study was planned to examine the factors associated with pain, fatigue, and sleep quality in E-Athletes.

Rhythmic Gymnastics is an Olympic discipline featuring individual or team competition. Regardless of the type of competition, athletes undergo rigorous training focused on enhancing their coordination, joint range of motion, and jump height. Each rhythmic gymnast voluntarily underwent testing at their own gym after reading and signing the informed consent document. During the first session, general information was collected on all participants (age, weight, and height), followed by an assessment of athletic performance and joint mobility parameters. For the jump performance parameters, the Counter Movement Jump test (CMJ) was used through an optical detecting system. An inertial sensor was used to measure joint mobility, while a pressure platform was used to measure ankle stability, using a single-leg jump protocol. Subsequently, participants were randomly divided into two groups: an experimental group (EG) and a control group (CG). The EG performed three sets, each lasting 60 seconds, with a 30-second break between sets for two times for week for 3 weeks. During each FR session, a complete sequential movement was always performed, starting from the gastrocnemius muscles and ending with the soleus muscle. At the end of the three weeks, all measurements were repeated.
NCT07092930

NCT07056231
Background: Sitting volleyball is a sport that relies primarily on upper body strength and anaerobic capacity. In critical in-game skills such as serve and spike, factors such as speed-endurance time and impact power play a decisive role in performance. There are limited studies in the literature examining the effects of low-dose caffeine consumption on these skills. The effects of ergogenic supplements in Paralympic sports have not been sufficiently investigated, and the potential benefits of caffeine on serve and spike performance in sitting volleyball players remain unclear. Purpose: The main purpose of this research was to determine the effects of low-dose caffeine (3 mg/kg) consumption on the serve speed, spike speed and Speed-Endurance performances of elite-level sitting volleyball players. Method: The study was designed using a randomized, double-blind, balanced, and crossover experimental design. 13 elite male athletes from the 2024 Paravolley European Champion Sitting Volleyball Men's National Team participated in the study. Participants were evaluated for serve speed, spike speed, and speed-endurance performances in both 3 mg/kg caffeine (CAF) and placebo (PLA) conditions.

Creatine supplementation (CS) offers numerous health benefits, with no proven side effects reported to date. CS positively impacts all organs and systems of the body. However, there is an ongoing effort among several creatine-producing companies to develop increasingly pure creatine formulations that generate fewer renal metabolites. Therefore, this study aims to evaluate the effects of a new creatine formulation, CreaSafe®, synthesized by the Chinese company Wenda®, on kidney function in athletes and patients with chronic obstructive pulmonary disease (COPD), as well as its effects on skeletal muscles and cardiopulmonary function. Regarding the athletes (Study 1), the sample will consist of 80 healthy athletes (40 strength-training athletes and 40 middle- and long-distance runners). Among each group of 40 athletes, 20 will receive CreaSafe® creatine (0.03 g/kg/day), while the other 20 will receive a placebo (microcrystalline cellulose; 0.03 g/kg/day), for 90 days, orally administered in water in the morning (between 7:00 a.m. and 9:00 a.m.). For the COPD patients (Study 2), 60 patients with severe and/or very severe COPD will be recruited. Of these, 30 will receive CreaSafe® creatine (0.03 g/kg/day), while the other 30 will receive placebo (microcrystalline cellulose; 0.03 g/kg/day), also administered orally in water for 90 days in the morning (between 7:00 a.m. and 9:00 a.m.). The supplementation period for both studies will last 90 days, with assessments performed at baseline and after 90 days. Kidney function will be evaluated through urinalysis (Urine Type I), the balance of pro- vs. anti-inflammatory cytokines, and levels of urea, creatine kinase (CK), and creatinine. Body composition will be assessed using octopolar and multifrequency bioimpedance, along with circumference measurements of body segments. Muscle strength of different muscle groups will be assessed using the E-lastic dynamometer. Biomarkers of skeletal muscle degradation and recovery will also be measured in plasma, including CK, lactate dehydrogenase (LDH), urea, myoglobin, and the levels of IL-1beta, IL-4, IL-6, IL-10, TNF-alpha, Atrogin-1, MuRF-1, and GDF-8 (myostatin). Whole blood analysis (erythrocytes, leukocytes, and platelets) will be performed using a fully automated blood analyzer (Sysmex XS 800i). Pulmonary function will be assessed through pre- and post-bronchodilator spirometry, as well as maximal inspiratory (PIMax) and expiratory (PEMax) pressures using a manovacuometer. Cardiovascular function will be evaluated using electrocardiography (ECG) and cardiovascular hemodynamics assessed by impedance cardiography (PhysioFlow). GraphPad Prism 5.0 software will be used for statistical analyses and graph generation. Paired Student's t-tests will be used to compare pre- and post-intervention values within each group, and unpaired Student's t-tests will be used to compare deltas between the CreaSafe® and placebo groups. Statistical significance will be considered at p ≤ 0.05.
NCT06937190
This study is a randomized, double-blind, placebo-controlled trial designed to examine the effects of pre-sleep creatine monohydrate supplementation on anaerobic performance and muscle damage markers in recreationally active females. Participants will be randomly assigned to receive either 5 grams of creatine monohydrate or a placebo 30 minutes before sleep for seven consecutive days. Anaerobic performance will be assessed using the Wingate Anaerobic Test, evaluating peak and average power output and fatigue index. Blood samples will be collected before and after the supplementation period to analyze markers of muscle damage, including creatine kinase and lactate dehydrogenase. This study aims to provide insight into the efficacy of short-term, time-specific creatine supplementation for enhancing performance and recovery.

Efficacy of an Innovative Kinesiotaping Bandage Compared to Traditional Tape in Stabilising Ankle Inversion and Plantar Flexion in Triathletes: A Triple-Blind Experimental Study. Background and Purpose: Lateral ankle sprains are a common injury among triathletes, impacting their performance and recovery time. Although traditional functional tape is effective in stabilising the ankle joint, it has limitations in aquatic sports due to its lack of water resistance. This study will evaluate the efficacy of an innovative kinesiotaping (KT) bandage, designed to combine water resistance with the restrictive properties of traditional tape. The primary objective will be to determine which type of bandage is more effective in stabilising ankle inversion and plantar flexion in triathletes. Study Design: This will be a triple-blind experimental study involving 20 federated triathletes. Each participant will have three different bandages (traditional tape, innovative KT, and placebo) applied in a randomised order. Goniometric and functional tests will be used to measure the outcomes. Interventions: Traditional Tape: Standard restrictive bandage. Innovative KT Bandage: Elastic, water-resistant bandage with additional restrictive properties. Placebo: Gauze bandage without stabilising properties. Methods of Evaluation: Goniometric measurements (flexion, inversion) and functional tests (Star Excursion Balance Test, Hopping Test, Vertical Jump Test) will be conducted. The bandages will be applied and evaluated in a controlled environment, with participants and investigators blinded to the type of bandage. Expected Outcomes: It is anticipated that the innovative KT bandage will provide stabilisation comparable to traditional tape for critical ankle movements while overcoming the limitations of tape in aquatic conditions. It is also expected to demonstrate significant advantages in functional tests. Clinical Relevance: This study aims to provide evidence for optimising the management of ankle injuries in triathletes, offering a practical and effective solution to maintain athletic performance under demanding conditions.
NCT06656858

NCT06544252
The objective of this research is to determine the influence of low and high glycemic index Malaysian pre-exercise mixed meals on endurance exercise performance in a hot-humid environment. Glycemic index (GI) is a method used to classify CHO-containing foods based on their influence on postprandial blood glucose when compared to the response on blood glucose after ingesting the same amount of CHO from a reference food (glucose or bread). Low GI (LGI) foods are digested and absorbed more slowly as compared to high GI (HGI) foods, resulting in a stable rise in blood glucose levels. The participants were trained male endurance long-distance runners. On the day of experimental trials, they consumed pre-exercise rice-based mixed meal, either LGI or HGI 3 hours before endurance running exercise. After that, they ran for 45 minutes at constant running speed equivalent to 70% VO2peak, followed by 10km time-trial. The respiratory gases, blood measures, rectal and skin temperature were measured throughout the running test.
NCT06200493

Sport specialization requires an understanding of morphological variability to optimize performance. However, the current literature lacks a detailed analysis of the anthropometric profile of track and field athletes, especially in Latin America. Additionally, the five-way fractionation method of body mass has been under-documented. These gaps highlight the need for more research to maximize the potential of athletes, particularly in emerging countries like Mexico. This study aims to determine the anthropometric characteristics of elite and Olympic Mexican track and field athletes. A descriptive cross-sectional study will be conducted. Forty-three anthropometric variables will be assessed to characterize the athlete´s physical composition using the standards of the International Society for the Advancement of Kinanthropometry (ISAK). Those variables will be used to describe the anthropometric profile (Heath and Carter somatotype, body composition through five-way fractionation method, muscle bone index, muscular adipose index, sum of skinfold thicknesses, and proportionality through Ross \& Wilson Phantom strategy. Correspondences of those variables will also be established among different tests and specialties: sprint, middle-distance, long-distance, endurance, combined events, jumps, and throws. This study aims to provide the opportunity to generate reliable references for high-performance Mexican athletes.
NCT06377306
Despite a rise in the number of women participating in competitive sports, there remains a gender gap within sport and exercise science literature. Studying females involves potential "noise" through the change in hormone concentrations during the different phases of the female menstrual cycle (MC) which can potentially affect physiological parameters, thereby making study design and interpretation of findings difficult. Longitudinal data on the acute and chronic combined effects of training load and MC phases on circulating female hormones in elite and non-elite female athletes is lacking. The investigators aim to characterize and track the potential effects of training load and MC phases on performance, anthropometric measures, sport emotions, intestinal microbiome, serum metabolites and injury prevalence in elite and non-elite female athletes. 200 competitive premenopausal female athletes will be recruited. In a longitudinal observational design, each participant will be followed for 1 year, and tested at three time points. At each point, data will be collected on two occasions reflecting distinct phases of the MC. Finding the possible relationship between the MC phases, training load and performance or specific bio-markers for training load are of utmost importance and can assist professionals to identify periods of high load and over-training, thus preventing injuries and training adjustment.

COVID-19 can cause myocarditis, which can cause myocardial fibrosis. This has been shown to increase mortality and morbidity among athletes. Several efforts have been made to guide sports participation after COVID-19, but not much scientific evidence is present to back-up those guidelines. The current initiative aims gain a heightened insight in this matter.To identify the presence of fibrosis athletes who recovered from COVID-19 will undergo CMR (Cardiac MRI). All athletes will also undergo echocardiography, 5-day Holtermonitoring among others. This will allow to determine whether differences between those with and those without fibrosis are present. If fibrosis is present, athletes will be offered an implantation of a very small monitoring device that will be able to detect arrhythmias with a much higher sensitivity. Also an exercise echocardiography will be performed, to determine the safety of continuation of athletic efforts. Amendment: Recently myocarditis and pericarditis have also been observed after the administration of mRNA-vaccines, specifically after the second dose. The effect of vaccination on exercise capacity is less clear. To investigate this we propose to amend the inclusion criteria for COVIDEX with "athletes undergoing or having undergone COVID vaccination"
NCT06134778
The goal of this clinical trial is to learn about in inspiratory muscle training on cardiorespiratory capacity, pulmonary function, respiratory muscle strength, sports skills, and quality of life of wheelchair rugby athletes. The main question\[s\] it aims to answer are: * Are the wheelchair rugby athletes show better results in cardiopulmonary assessment tests in safety and effort, in the post- inspiratory muscle training period, when compared to their results in the pre-inspiratory muscle training period? * Is inspiratory muscle training capable of increasing ventilatory capacity at rest and during exertion? Participants will be evaluated through questionnaires, laboratory and field tests, such as: * Pulmonary function (spirometry), * Inspiratory muscle strength (manovacuometry), * Cardiorespiratory capacity under exertion (cardiopulmonary exercise test), * Wheelchair rugby specific skills (Beck Battery) * Quality of life (WHOQOL-DIS) .
