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.
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.
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 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.
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.
NCT06406764

NCT05936398
Two groups of healthy, highly trained triathletes trained respiratory muscles with one of the two methods: voluntary isocapnic hyperpnoea (VIH) or inspiratory pressure threshold loading (IPTL). The main purpose of this study was to accurately and thoroughly assess the potential extra load that RMT puts on athletes and determine if there are significant differences in RMT-induced load between the investigated training methods. Informed written consent was obtained from the all study participants. All procedures were carried out in accordance with the Declaration of Helsinki.
NCT05207332
The feeding strategies during recovery are essential to optimize a subsequent performance. Carbohydrate is a major fuel source during exercise as it has been shown to maintain high rates of carbohydrate oxidation. Protein intake in combination with carbohydrate have been shown to increase Amino acid bioavailability and may alter physiologic responses during exercise, which may be relevant to endurance performance. The goal of this study is to assess the effect of a new developed vegan product on athletes recovery and subsequent performance.

Athletes using inhaled β2-adrenoreceptor agonists (IBAs) win a disproportionate number of medals. However, most previous research has shown that β2 agonists do not improve exercise performance in either asthmatic or non-asthmatic athletes. Although the majority of these studies do not show an ergogenic effect, the small number of studies with extended exercise bouts (\~60 minutes) do show an advantage. The investigators believe that a controlled yet sport-specific exercise protocol will elucidate this ergogenic effect. Because IBAs may have different effects on these two groups of athletes, the investigators will measure exercise performance in both female and male elite cyclists. The investigators hypothesize that athletes will perform better during a combination steady-state/sprint exercise task following salbutamol administration.
