NCT07659301
This study examines whether exposition to hyperbaric oxygen after a road-race simulation can help competitive cyclists recover and perform better the following day. Hyperbaric oxygen, which involves breathing oxygen inside a pressurized chamber, is used as a recovery method in elite and professional sport. Its effectiveness, however, remains controversial: despite this widespread use, there is a lack of solid scientific evidence that a single HBO session after strenuous endurance exercise actually improves recovery, or that clarifies how the amount of oxygen exposure influences any benefit. The study includes healthy male road cyclists between 18 and 40 years of age who compete at the national level in Belgium. After completing a fatiguing cycling session, each participant is randomly assigned to one of four groups receiving different levels of oxygen exposure during recovery. Two groups breathe oxygen under increased pressure inside a chamber at either 2.5 or 1.4 atmospheres absolute. A third group breathes oxygen at normal pressure. The fourth group receives a sham condition that reproduces the treatment setting without active oxygen exposure. The study is double-blind, meaning that neither the participants nor the researchers assessing the outcomes know which condition each participant receives. The main goal is to determine whether a single session of post-exercise HBO improves next-day endurance performance, and whether higher oxygen exposure produces greater effects. The researchers also collect blood samples and physiological measurements to better understand how the body recovers.

New Zealand blackcurrant (NZBC) is a supplement made from a berry naturally rich in plant compounds called anthocyanins. Researchers have studied these compounds for years and found that they may help the body by improving blood flow, reducing post-exercise stress on the body, and supporting energy production. Most of that research, however, has focused on endurance athletes like runners and cyclists. Almost nothing was known about whether NZBC could benefit people who do strength training. That is what this study was designed to find out. Twenty healthy, resistance-trained men and women between the ages of 18 and 40 were recruited. Each participant completed four different conditions over the course of the study: taking no supplement at all, taking a placebo (a dummy capsule with no active ingredient), taking a low dose of NZBC (250 mg per day for seven days), and taking a higher dose of NZBC (600 mg per day for seven days). Neither the participants nor the researchers evaluating them knew which capsule was being taken at any given time, a design that helps ensure the results are as reliable as possible. At the end of each seven-day period, participants came into the lab and completed a full battery of tests. Measurements included how much weight could be lifted for one maximum effort on the bench press and leg press, how much total volume could be completed across multiple sets, and how fast and powerfully the bar could be moved. Participants also completed a 30-second all-out cycling sprint to test anaerobic fitness, and a paper-and-pencil color-word test to measure focus and mental sharpness. Strength increased noticeably. After taking either dose of NZBC, participants were able to lift more weight on both the bench press and leg press than when taking the placebo or no supplement. The lower dose had a particularly striking effect on leg training: participants pushed through roughly 38% more total volume in their leg press sets. For bar speed and explosive power on the bench press, the higher dose had the edge. Cognitive performance followed a similar pattern. The lower dose sharpened mental performance across several parts of the color-word test, while the higher dose made a more modest but still meaningful difference on one section. The sprint cycling test showed no differences between conditions. Importantly, both doses were safe and well-tolerated, with no meaningful side effects reported throughout the study. One week of supplementation was sufficient to produce real differences in strength, power, and mental sharpness, and neither dose raised any safety concerns.

The goal of this randomized clinical trial is to learn whether an individualized rowing training program based on ventilatory thresholds can improve aerobic capacity and 2,000 m rowing performance in youth rowers from Valdivia, Chile. The study will include male and female rowers aged 14 to 18 years who train regularly at Club de Remeros Arturo Prat. The main questions it aims to answer are: Does ventilatory threshold-based individualized training improve maximal oxygen uptake compared with the usual club training program? Does ventilatory threshold-based individualized training improve 2,000 m rowing ergometer performance compared with the usual club training program? Researchers will compare an individualized training group with a usual training group to see if prescribing exercise intensity based on each rower's ventilatory thresholds produces greater improvements in aerobic capacity, rowing performance, and related physiological measures. Participants will: Complete baseline and post-intervention assessments, including a cardiopulmonary exercise test on a rowing ergometer, blood lactate measurements during an incremental rowing test, a 2,000 m rowing ergometer test, body composition assessment, and respiratory muscle strength testing. Be randomly assigned to either an individualized training group or a usual training group. Complete a 12-week rowing training program. Use heart rate monitors during study training sessions so that training intensity, adherence, and safety can be monitored. Report any discomfort, injuries, or adverse events during the study. The individualized training group will train according to heart rate zones derived from each participant's ventilatory thresholds measured at baseline. The usual training group will continue the club's regular training program. The study will also explore individual variability in training response and the proportion of participants who respond or do not respond to each training approach.

This randomized single-blind crossover trial investigated the acute effects of three different exercise modalities, namely self-myofascial release with a foam roller, dynamic stretching, and static stretching, on posture, flexibility, dynamic balance, and lower-extremity performance in adolescent karate athletes (12-18 years). Participants attended four weekly sessions at the same time of day and after a 48-hour rest period. In the first week a baseline (control) measurement was performed, and in the following three weeks each participant received the three interventions in a randomized order. Outcomes included a four-view smartphone-based posture analysis (PostureScreen Mobile), the Sit-and-Reach Test, the Y Balance Test, the 30-second Sit-to-Stand Test, and the Vertical Jump Test (My Jump Lab 2). The aim was to identify which warm-up modality offers the greatest acute benefit before karate-specific performance

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.
NCT07438522
This randomized clinical trial aims to determine the effects of targeted isometric and isotonic hand strengthening exercises on hand function, dexterity, grip strength and grip endurance in competitive female badminton athletes aged 18-30 years. Participants will be randomly allocated into two groups receiving either isometric or isotonic hand strengthening exercise programs performed three times per week for six weeks. Outcome measures will be assessed at baseline, 3rd week and 6th week using Michigan Hand Outcomes Questionnaire (MHQ), Purdue Pegboard Test or Nine-Hole Peg Test, Hand Dynamometer Test and Sustained Grip Test.

Effects of High-Intensity Interval Training on Physical and Physiological Parameters in Adolescent Female Field Hockey Players High-Intensity Interval Training (HIIT) is a training method that alternates short periods of intense exercise with recovery periods. It is commonly used to improve athletic performance. This study investigated the effects of an 8-week HIIT program on physical and physiological performance in adolescent female field hockey players. Participants were divided into two groups: one group continued their regular field hockey training, while the other group completed additional HIIT sessions three times per week. After the intervention, the HIIT group demonstrated improvements in aerobic capacity (VO₂max), reaction time, balance, and standing long jump performance. A decrease in flexibility was observed in this group. The control group showed reductions in aerobic capacity and flexibility. The findings suggest that adding HIIT to regular field hockey training may improve several key performance parameters in adolescent female athletes.

In this study, the investigators will examine the effect of cold-water immersion (CWI) on objective and subjective recovery metrics, as well as simple performance metrics, in National Collegiate Athletics Association (NCAA) Division I Men's and Women's Volleyball players, Men's Football players, and Men's and Women's Cross Country runners. This is a cohort cross-over study that will take place over the course of four weeks during an intensive training cycle. Participants will wear a WHOOP monitoring device on their wrists at all times during the study period. The two-week intervention will consist of ten minutes of CWI to take place within one hour of the completion of the last training session of the day. The target water temperature will be 55 degrees Fahrenheit, and each participant will complete five sessions of CWI per week (for a total of ten sessions over the two-week intervention phase). Objective recovery measures will include heart rate variability, resting heart rate, total sleep time, slow wave sleep time, sleep consistency, blood oxygenation, and nocturnal skin temperature, all of which will be collected continuously by the WHOOP monitoring device. Subjective recovery measures will include three surveys to be completed daily, including the Likert Scale of Muscle Soreness, the Total Quality Recovery Scale, and the Single-Item Sleep Questionnaire. Performance measures will include a counter-movement jump to be completed two times per week, an isometric mid-thigh pull to be completed once per week, and a drop jump to be completed once per week. These outcome measures will similarly be collected during the two-week control period, during which participants will not have access to CWI following training sessions.

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.

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.

Korfball is a mixed-gender team sport that requires high levels of coordination, balance, and physical fitness. Unlike basketball or netball, players cannot dribble or run with the ball, and shots must often be taken in a single-leg, step-back position. These unique demands create challenges for athletes' strength, balance, and injury prevention. Despite korfball's growing popularity, scientific research on the sport's physical, biomechanical, and training characteristics remains limited. Complex training (CT) is a training method that alternates heavy resistance exercises with plyometric movements. This approach is known to improve strength, power, sprinting, and jumping ability in other team sports. It is especially relevant for unilateral sports movements, which are common in korfball shooting and defensive actions. However, no studies to date have applied CT to korfball athletes, and the effects of such training on their performance, biomechanics, and interlimb asymmetries are unclear. This study is designed to address three research areas: To describe the internal and external load characteristics of korfball matches using heart rate monitoring and video-based analysis. To investigate limb asymmetry in korfball players through assessments of biomechanics, anthropometry, physical fitness, and shooting technique. To evaluate whether a 10-week unilateral complex training program can reduce limb asymmetry and improve physical fitness and shooting performance in elite players. The study includes both cross-sectional and interventional components. First, competition loads will be monitored to understand game-specific demands. Second, assessments will compare dominant and non-dominant limbs in terms of strength, biomechanics, and technical performance. Finally, athletes will undergo a 10-week unilateral complex training program, after which the same measures will be repeated to test for improvements. The expected outcomes are a clearer understanding of the physiological and biomechanical characteristics of korfball players, as well as evidence on the effectiveness of unilateral complex training. This knowledge may guide coaches and practitioners in designing targeted training strategies to enhance performance, reduce injury risk, and optimize athlete development in korfball.

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.
NCT07221305
The purpose of this study is to assess both the feasibility and efficacy of a 6-week mobile-application-based neuromuscular training program in high school athletes by measuring adherence rates and examining changes in agility and neuromuscular control. Outcomes were measured both during the intervention (adherence) as well as at pre- and post-intervention data collection sessions.
