NCT07484425
This randomized controlled trial aims to determine the effects of different drop height plyometric training protocols on lower limb explosive strength, anaerobic power, and change of direction (COD) performance in soccer players. A total of 56 competitive soccer players aged 18-30 years will be randomly allocated into three intervention groups using sealed envelope randomization: low drop height (30 cm), moderate drop height (45 cm), and high drop height (60 cm) plyometric training groups. Participants will undergo supervised plyometric training three times per week for six weeks. Outcome measures including Vertical Jump Test, Running-Based Anaerobic Sprint Test (RAST), and T-Test Agility Test will be assessed at baseline and post-intervention. Statistical analysis will be performed using SPSS version 25 to determine within-group and between-group differences.
NCT07473440
This randomized controlled study investigates the effects of sport-specific training on aerobic adaptation and circulating biomarker responses in trained combat athletes. Exercise induces systemic physiological adaptations through signaling molecules known as exerkines, including myokines and adipokines, which mediate communication between skeletal muscle and other metabolic organs. Forty trained male kickboxers are randomly assigned to either an experimental training group or a control group. The experimental group performs an eight-week sport-specific conditioning program in addition to regular technical training, while the control group maintains their usual training routine. Aerobic capacity is assessed using maximal oxygen uptake (VO₂max). Blood samples are collected before and after the intervention to determine circulating levels of exercise-responsive biomarkers, including myostatin, irisin, apelin, brain-derived neurotrophic factor (BDNF), fibroblast growth factor-21 (FGF21), and adiponectin. The primary objective of the study is to evaluate whether changes in circulating biomarker responses are associated with improvements in aerobic performance. The findings may provide insight into the molecular mechanisms underlying exercise-induced physiological adaptation in combat athletes.
NCT07457398
This study investigates the acute and 24-hour recovery effects of localized muscle fatigue on the viscoelastic properties of the medial gastrocnemius (MG) muscle and vertical jump performance. The research aims to quantify the changes in muscle stiffness, tone, and elasticity immediately after a standardized fatigue protocol and to monitor the recovery of these parameters 24 hours later. Additionally, the study evaluates the impact of fatigue on explosive power, measured by countermovement jump (CMJ) height, across these time points.
NCT07407478
Brief Summary The purpose of this study is to investigate the effect of foot core exercises on jump performance in professional volleyball players. Participants will be randomly assigned to two groups. The first group will perform a strength training program only, while the second group will perform foot core exercises in addition to the same strength training program. Jump performance will be assessed using the Countermovement Jump (CMJ) test, and performance scores will be obtained through force-time analysis using the ForceDecks system. The findings of this study are expected to contribute to the development of training programs aimed at improving performance and reducing injury risk in professional volleyball players.
NCT06970964
This study aims to evaluate whether a fermented milk drink containing the probiotic strain Lacticaseibacillus paracasei strain Shirota (LCS), commonly found in Yakult®, can help reduce upper respiratory symptoms in triathletes before and after competition. Athletes often experience cold-like symptoms due to physical stress, intense training, and immune system challenges. The study investigates whether daily consumption of this probiotic drink can help improve immune response and reduce the incidence or severity of symptoms such as sore throat, nasal congestion, or coughing. This is a randomized, double-blind, placebo-controlled, parallel-group study involving healthy adult triathletes. Participants will be randomly assigned to receive either the probiotic drink or a placebo for a specific period before and after a triathlon event. Symptoms and health markers will be tracked through questionnaires and biological samples. The goal is to explore whether probiotic supplementation can provide practical, non-pharmacological support for athletes' immune health and well-being during intense physical activity.
NCT07314645
Background Daytime napping is increasingly incorporated into athletic recovery routines to manage sleepiness and support alertness. However, the effects of different nap durations on high-intensity anaerobic performance tasks remain insufficiently characterized, particularly in team-sport settings. Nap duration and circadian timing may influence psychomotor readiness, perceived exertion, and fatigue-related responses, yet existing evidence is limited and inconsistent in adolescent athlete populations. This study is designed to examine the acute effects of two daytime nap durations within a controlled experimental framework. Methods This study will employ a randomized, crossover design involving sixteen competitive male adolescent soccer players classified as intermediate chronotypes. Each participant will complete three experimental conditions in a randomized order: no nap (N0), a 25-minute nap (N25), and a 45-minute nap (N45), with standardized washout periods between sessions. Nap compliance will be objectively monitored using wrist-worn actigraphy. Following each condition, participants will observe a standardized 60-minute post-nap wakefulness period prior to performance testing. Agility performance will be assessed using the Pro Agility Test, and anaerobic endurance will be evaluated using a repeated-sprint ability (RSA) protocol. Psychophysiological measures will include ratings of perceived exertion (RPE), the Hooper Index, visual analogue scales (VAS) for subjective alertness, and mood states assessed via the Profile of Mood States (POMS). These outcomes will be collected to compare responses across nap conditions. Objectives The primary objective of this study is to compare the acute effects of two daytime nap durations (25 minutes vs 45 minutes) on agility performance in adolescent soccer players without a habitual napping routine. Secondary objectives include examining nap-related differences in repeated-sprint performance indices, perceived exertion, subjective alertness, and mood states.

NCT07279753
This study examined the effects of a tactical training program based on critical thinking (TPCT) on the tactical efficiency and decision-making performance of university futsal players. The intervention was designed to strengthen players' ability to interpret the dynamics of play, anticipate opponents' actions, and generate adaptive tactical responses under competitive conditions. The program followed a socio-constructivist framework, promoting learning through problem solving and interaction among teammates. Training sessions combined representative game situations, reflective questioning, and guided tactical discussions. A single-group pre-post design was implemented. Thirteen university players participated voluntarily after providing informed consent and receiving approval from the institutional ethics committee. Data were collected before and after the intervention to assess individual and collective tactical performance, goal effectiveness, and time of ball possession. The study aimed to provide evidence on the educational and performance impact of a critical thinking-based tactical approach in futsal, contributing to contemporary models of athlete development and pedagogical innovation in team sports.
NCT07274566
This study aims to examine the effects of an eight-week Exer-Genie®-assisted speed and agility-balance-coordination (ABC drill) training program on sprint performance, hamstring muscle strength, and vertical jump ability in young female football players. A total of 37 licensed female football players competing in the Turkish Women's Second League participated in the study. Participants were randomly assigned to an experimental group (n = 20) or a control group (n = 17). The study evaluates whether this integrated training approach enhances acceleration, force production, and neuromuscular control compared to regular team training alone.
NCT07249203
This study investigated the effects of resistance training applied with a velocity-based approach on selected motor skills in university-level athletes. Participants were randomly assigned to two groups: a velocity-based training (VBT) group and a percentage-based training (PBT) group. Both groups performed lower-body resistance exercises over an 8-week period, three times per week. Pre- and post-training assessments were conducted for countermovement jump (CMJ), sprint (20 m and 40 m), agility (505 test), and one-repetition maximum (1RM) squat performance. The aim of this study was to compare the effects of VBT and PBT on jump, sprint, agility, and strength performance. It was hypothesized that the VBT group would show greater improvements in motor skills compared to the PBT group.
NCT07170930
The goal of this study is to investigate the effects of varying friendly match-play exposure during the late pre-season on physiological, biochemical, and performance adaptations in soccer players. It is hypothesized that (i) significant changes will occur across the pre-season in both the extended- and limited-play groups when analysed independently; (ii) distinct group-specific adaptations will emerge by the end of the preparatory period; and (iii) match-play exposure, when analysed across all participants, will be significantly correlated with physiological and performance outcomes at pre-season completion. Players from a randomly selected team will be assessed at three time points: pre-season start, mid-pre-season (MPS), and pre-competition phase (PC). Assessments will include anthropometry, physical performance, and markers of muscle damage, inflammation, hormonal status, and haematology. Based on the total match-play time of 8 friendly games during the late pre-season, players will be retrospectively categorised into extended-play (EP) and limited-play (LP) cohorts.time of 8 friendly games during the late pre-season, players will be retrospectively categorised into extended-play (EP) and limited-play (LP) cohorts.

This randomized controlled trial aimed to investigate the effects of casein supplementation timing on post-exercise recovery and exercise performance in trained football players. Participants were allocated into three groups: pre-sleep casein ingestion, post-exercise casein ingestion, and control. The study compared the effects of pre-sleep and post-exercise casein intake on anaerobic performance, agility, and recovery markers following a standardized high-intensity resistance training session.
NCT07171398
This study investigated how chronic ankle instability (CAI) affects functional performance in athletes compared with healthy controls. CAI is a condition that develops after repeated ankle sprains, leading to ongoing "giving way" episodes, pain, and reduced stability. A total of 32 athletes participated: 16 with CAI and 16 healthy, age- and sport-matched controls. Participants performed a series of sport-specific functional performance tests, including single-leg hop tests, triple crossover hop, lateral hop, 6-meter timed hop, side jump, countermovement jump (CMJ), the 5-10-5 agility test, and the acceleration-deceleration-acceleration (ADA) test. The Deepsport AI program was used for precise measurement of jumping and agility parameters. Results showed that athletes with CAI had significantly lower jump height and power, reduced hop distances, and slower times in agility and hopping tests compared to controls. These findings suggest that CAI negatively impacts performance in explosive and multidirectional movements, which are essential in sports such as basketball, volleyball, and soccer. No strong correlation was found between CAIT (Cumberland Ankle Instability Tool) scores and objective performance outcomes, suggesting that subjective reports alone may not fully capture functional deficits. This study highlights the importance of using both subjective questionnaires and objective tests to evaluate ankle instability in athletes. It also supports the need for rehabilitation programs that include not only balance and proprioception training but also specific exercises to improve jumping, agility, and multidirectional performance.
NCT07109089
The goal of this randomized controlled trial is to compare adherence to training prescription-defined as the percentage of time spent within the prescribed intensity zone-using either a race pace-based method or a heart rate-based method in male and female recreational distance runners. The main research questions are: * Which training prescription method leads to greater adherence in recreational runners? * Which method results in more accurate execution of low- and high-intensity interval training sessions? Participants will undergo anthropometric and physiological assessments to determine training zones based on ventilatory thresholds. In addition, a 5-km time trial will be performed on a standard track to establish individual race pace zones.

Basketball is a popular team sport where athletes score points by successfully shooting the ball into the basket. Accuracy in shooting is crucial for players to score points effectively. Pre-workout supplements (PWS) have garnered interest from athletes and fitness enthusiasts due to the purported synergistic action of their ingredients which, when consumed before training, may help improve athletic performance. The acute effect of PWS or similar on the shooting accuracy of basketball athletes has not yet been investigated. Therefore, this study aimed to investigate the acute effect of a caffeine-based PWS (containing caffeine, creatine, β-alanine, citrulline malate, and BCAAs) on the stationary free throw, two-point, and three-point shooting accuracy in basketball players.

This request pertains to a series of related projects on a common theme. Specifically, this set of projects aims to analyze the impact of new alternatives in materials and structures of artificial turf on athlete performance and perception, within the context of the elimination of microplastics as per Commission Regulation (EU) 2023/2055 of September 25, 2023. Third-generation sports artificial turf is notable for including performance infill (granules) that provide the necessary functionality and safety for sports practice. The vast majority of fields worldwide use materials that do not comply with the new European regulation, which has granted an eight-year moratorium. Therefore, there is little time to find new alternatives. The challenge lies not only in developing new structural solutions but also in understanding their impact on athletes. This issue is of high severity, as these sports facilities are the largest in terms of space and host the highest number of Physical Activity and Sports practitioners in Europe (mainly Football, Rugby, Hockey, and Padel). For this reason, over the past year, the IGOID Group has requested various projects to cover all the necessary phases and nuances to address this issue. The activities included in these projects are divided into two phases: Phase 1: Evaluation of Sports Surfaces in the Laboratory (durability and surface-player and surface-ball interaction). Tests will be conducted on artificial turf samples constructed with SBR rubber (the main material to be replaced under the EU regulation), natural-origin infills, polymeric infills larger than 5 mm, and other infills. Initially, a market analysis and classification will be carried out, followed by laboratory tests. Across all projects, a minimum of 30 alternatives are expected to be analyzed. Phase 2: Field Study. Tests will be conducted on a sample of athletes on constructed surfaces representing the different alternatives evaluated in Phase 1. Performance tests and a battery of assessments will be carried out to understand athlete perception. A sample of 30 athletes will be randomly divided into groups to perform different repetitions of the test batteries, covering a minimum of six different sports facilities.
NCT06927778
The goal is to learn if a Functional Corrective Training (FCT) exercise program improves posture, core muscle endurance, jumping ability, and reaction time in adolescent fencers. The main questions it aims to answer are: Does the FCT program improve trunk muscle endurance? Does the FCT program enhance athletic performance, such as jump height and reaction time? Researchers will compare adolescent fencers who receive an 8-week FCT exercise program to those who continue regular training only. Participants will: Be assigned randomly to either an exercise group (FCT) or a control group Undergo Functional movement screen, endurance, jumping, and reaction time assessments before and after the 8-week period Continue their usual fencing training throughout the study The study will help determine whether adding corrective exercises to standard training can improve function and performance in young athletes.
NCT06551935
Sleep is essential for recovery and performance in athletes, yet they often struggle with inadequate sleep duration and quality. Theoretically, strategies such as sleep extension and sleep hygiene could improve sleep and subsequent recovery in athletes, but their effectiveness remains largely unstudied in the literature. This study aimed to analyze the effects of sleep extension and sleep hygiene on physical and cognitive performance in soccer players.
NCT06681311
The inclusion of dryland training and stabilization exercises is crucial for optimizing performance and reducing injury risk in master swimmers. Exercises targeting core stabilization play a significant role in enhancing overall body strength and endurance, thereby improving swimming performance. Shoulder stabilization exercises address common issues faced by swimmers, such as shoulder impingement and rotator cuff injuries, contributing to the prevention of such injuries. Incorporating these exercises into the training regimen enables master swimmers to improve their posture, balance, and strength, resulting in more efficient performance in the water and reduced injury risk. Thus, a comprehensive training approach that includes both aquatic and stabilization exercises is of great importance for sustaining performance and ensuring long-term health in master swimmers. The aim of this study is to examine the effects of core and shoulder stabilization exercise training on athletic performance and injury risk in master swimmers. Our study is designed to include healthy swimmer participants. A minimum of 34 master swimmers aged between 25 and 50 years will be recruited for the study. Prior to the stabilization training program, participants will undergo several assessments including the Isometric Plank Test (Prone Bridge Test), Closed Kinetic Chain Test, Medicine Ball Throw Test, 50m Freestyle Test, and Functional Movement Screening for injury risk assessment. After initial testing, the control group will perform a 5-minute traditional dryland warm-up focusing on the shoulders, core, and lower extremities before swimming workouts. The experimental group will receive core and shoulder stabilization exercises in addition to the traditional dryland warm-up and routine swimming training for 6 weeks (2 days per week). To assess the effects of the intervention, all tests will be repeated at the beginning, at the end of the 6-week exercise program, and in the 12th week. The literature does not provide information on the relationship between combined core and shoulder stabilization exercises and performance or injury risk in swimmers. This study aims to address this gap in the literature by investigating whether there are significant differences in the results obtained from the exercises and to contribute to future research aimed at enhancing performance and reducing injury risk in athletes.
