The aim of this study was to examine the effects of high-intensity plyometric training (HIPT) on some parameters in elite soccer players in the U17. Volunteer soccer players were randomly divided into two groups according to their positions: the regular training (RT) group (age: 16.71 ± 0.47 years; stature: 163.46 ± 3.31 cm; body weight: 61.04 ± 1.59 kg) and the HIPT group (age: 16.64 ± 0.50 years; stature: 165.60 ± 3.03 cm; body weight: 59.76 ± 1.92 kg), and each group included five defenders, five midfielders, and four attackers. While the RT group did only routine soccer training, the HIPT group performed high-intensity plyometric training three days a week in addition to routine soccer training. In the study, body weight, stature, sprint (10 m, 30 m, and 40 m), jump (standing long jump, right and left-limb triple hop) and 5-0-5 change of direction speed test measurements of the soccer players were taken. Skewness and Kurtosis values obtained from the pre-test and post-test measurements were calculated to test whether the normality assumption of the study was met. A mixed measure two-way ANOVA test was used to determine the difference between the pre-test and post-test. The significance was set as p < 0.05. The results indicated that 8-week high- intensity plyometric training provided more improvement in measured performance parameters than routine soccer training. As a result, when the data obtained is examined, it can be said that HIPT had better values in sprint, jump, and change of direction parameters, so plyometric training was more beneficial for anaerobic parameters than routine soccer training in children. It is recommended that the trainers make their plans considering these results.

Background and Objectives: This study analyzes the effects of proprioceptive training on the physical fitness and soccer-specific technical skills of young professional soccer players. Materials and Methods: Twenty-eight male professional soccer players from the Türkiye Football Federation’s Third League, aged 20.46 ± 1.60 years (average), participated voluntarily. Body composition was assessed with the Inbody270 bioelectrical impedance analyzer, while agility and maximal VO₂ cardiorespiratory fitness were measured using the ChronoJump smartspeed mat. Soccer-specific technical skill assessments were also conducted. Data were analyzed using SPSS 22, with paired sample t-tests for comparisons, Cohen’s d test for effect size, and repeated measures two-way ANOVA for interaction effects (group × time). Eta squared (η²) values were reported for effect size. A 95% confidence level and p = 0.05 were used. Results: Proprioceptive training significantly improved body fat percentage (p < 0.05; η² = 0.006) and soccer-specific technical skills, including free juggling (p < 0.05; η² = 0.302), alternating foot juggling (p < 0.05; η² = 0.271), right foot juggling (p < 0.05; η² = 0.250), and shooting performance (p < 0.05; η² = 0.513). Conclusions: A 12-week proprioceptive training program, when incorporated into soccer practice, significantly enhances soccer-specific technical skills and reduces body fat percentage.

The aim of this study is to examine the impact of a 12-week gymnastics and ballet training on the balance and flexibility skills in pre-school children. The study was conducted with a total of 23 girls who had just started gymnastics (n = 11) and ballet (n = 12) in private sports clubs in Erzurum, Turkey. The verbal provocation method was used during the tests and exercises since the children aged 5-6 years may have low attention span. Also, some alternative methods (i.e. educational games) were used in cases where children were distracted. Flexibility of the children was measured on the sit-and-reach box, and their static balance was measured with the flamingo balance test. First, the pre-tests and then, after 12 weeks of training, the post-tests were administered, upon which the difference between the pre-test and post-test scores was estimated. Mann-Whitney U Test was used to examine the relationship between pre-test and post-test values. No statistical significance (p> 0.05) was found between the balance pre-test and post-test scores after 12 weeks of training, while a statistical significance (p<0.05) was found in terms of the flexibility scores. As a result, it turned out that the training did not affect the stabilization between the two branches, but it increased the flexibility development in gymnasts in comparison to ballerinas. This can be explained by the different development rates of balance and flexibility in children, and also by the fact that gymnastics and ballet develop children's bio-motor characteristics at different rates.

Background: Functional strength training (FST) has gained considerable attention due to its potential in enhancing muscle strength, endurance, and body composition, especially among athletes. The purpose of this study was to assess the effects of a 12-week FST program on performance outcomes such as muscle strength, muscular endurance, and body composition in elite male field hockey players.Methods: The study involved 28 male athletes from the Türkiye Hockey Federation Super League, with a mean age of 27.54 ± 1.34 years and an average athletic experience of 7.62 ± 0.48 years. The mean height of participants was 180.28 ± 4.54 cm, and their mean weight was 75.59 ± 3.08 kg. Participants were randomly divided into two groups: the experimental group (n = 14) and the control group (n = 14). Pre-intervention assessments were conducted to evaluate muscle strength (Leg Extension, Leg Curl, Bench Press, Pushdown), muscular endurance (30-s Sit-up and Push-up tests), and body composition [Body Mass Index (BMI) and Body Fat Percentage (BFP)]. The experimental group participated in the FST program three times per week for 12 weeks, while the control group maintained their usual training regimen. Post-test evaluations were performed using the same testing protocols. Statistical Analysis: Data were analyzed using two-way repeated measures ANOVA to assess the interaction effects of group and time (pre-test vs post-test). Partial eta squared (η²) values were used to report effect sizes, and statistical significance was set at p < 0.05. Data analysis was carried out using SPSS 22.0 software. Normality was assessed through the Shapiro-Wilk test, and data distribution was further examined through skewness-kurtosis values, histograms, box plots, and Q-Q plots. Paired sample t-tests were performed for pairwise comparisons, with Cohen’s d used to determine the effect sizes. The classification for effect sizes followed Hopkins’ (2002) guidelines: small (≥0.01), moderate (≥0.06), and large (≥0.14).Results: Significant group × time interaction effects were found for all measured variables (p < 0.05). The experimental group showed greater improvements in body composition, muscle strength, and muscular endurance compared to the control group. Specifically, the experimental group experienced a significant reduction in BMI (pre-test: 21.17 ± 0.64 kg/m², post-test: 19.84 ± 0.85 kg/m², p < 0.001) and BFP (pre-test: 15.36% ± 0.62%, post-test: 12.13% ± 0.47%, p < 0.001), while the control group showed minimal changes in these variables. Muscle strength improvements in the experimental group were significant for Leg Extension (pre-test: 83.93 ± 4.87 kg, post-test: 66.07 ± 4.01 kg, p = 0.003), Leg Curl (pre-test: 99.29 ± 7.81 kg, post-test: 118.21 ± 5.04 kg, p < 0.001), and Bench Press (pre-test: 66.43 ± 6.91 kg, post-test: 87.14 ± 4.69 kg, p < 0.001). In contrast, the control group did not show significant improvements in these tests. Muscular endurance was also superior in the experimental group for both the 30-s Sit-up (pre-test: 19.21 ± 0.97, post-test: 23.36 ± 1.28, p < 0.001) and Push-up (pre-test: 24.66 ± 2.53, post-test: 27.04 ± 0.81, p < 0.001) tests. Effect sizes (Cohen’s d) indicated moderate to large effects for all measured variables, with d values ranging from 0.46 to 1.14 for strength and endurance improvements.Conclusion: The findings of this study demonstrate that a 12-week FST program significantly improves muscle strength, endurance, and body composition in elite male field hockey players. These results suggest that incorporating FST into athletic training regimens may optimize performance and enhance overall physical fitness in athletes.

Background: Brain-derived neurotrophic factor (BDNF) is a key regulator of neuroplasticity, cognitive function, and mental health. Exercise is proposed as a non-pharmacological strategy to enhance BDNF; however, findings across neurological and non-neurological disorders remain inconsistent, and the influence of exercise type or dose-related parameters remains unclear. Objective: This meta-analysis evaluated the effects of exercise interventions on peripheral BDNF levels in individuals with neurological (e.g., multiple sclerosis, cognitive impairment, schizophrenia, depression) and non-neurological (e.g., obesity, type 2 diabetes, cancer) disorders, and examined whether outcomes varied by disease category, exercise modality, or dose. Methods: A systematic search of Web of Science, PubMed, ScienceDirect, Scopus, and Cochrane was conducted up to 1 October 2025. Eligible randomized controlled trials (RCTs) and the quality of evidence were assessed using the PEDro scale and the GRADE approach, respectively. Random-effects models were applied, with subgroup analyses (neurological vs. non-neurological; exercise type; duration and assay type), meta-regressions (duration, frequency, session length), and publication bias tests (funnel plot, Begg’s test, Egger’s regression, and trim-and-fill). Results: Nineteen RCTs, including 850 participants, were analyzed. According to low-quality evidence, exercise significantly increased peripheral BDNF (SMD = 1.03, 95% CI: [0.56–1.49, p < 0.0001). Effects did not differ significantly between neurological (SMD = 0.91, 95% CI: 0.31–1.50) and non-neurological (SMD = 1.23, 95% CI: 0.47–1.99) conditions (Q (1) = 0.44, p = 0.51). Subgroup analyses revealed significant improvements for resistance exercise (SMD = 1.57, 95% CI: 0.91–2.23), followed by aerobic (SMD = 1.44, 95% CI: 0.36–2.52) and combined exercise (SMD = 0.55, 95% CI: 0.21–0.89). Meta-regressions showed no moderating effects of duration (β = 0.0101, p = 0.834), weekly frequency (β = 0.1464, p = 0.648), minutes per session (β = −0.0124, p = 0.233) or total weekly minutes (β = 0.0005, p = 0.919) apart from age and baseline BDNF level factors (β = 0.0348, p = 0.020; β = −0.035, p = 0.0258). Publication bias tests indicated minimal publication bias, with adjusted effects remaining robust. Conclusions: Exercise interventions have been shown to increase peripheral BDNF significantly across diverse clinical populations. In particular, resistance and aerobic exercise protocols accounted for the exploratory component, whereas simple dose-related factors did not explain the variability. These findings are consistent with the biological plausibility of exercise-induced neuroplasticity and underscore the need for larger, pre-registered RCTs with harmonized biomarker protocols to strengthen clinical translation. However, the certainty of evidence is limited by small sample sizes and the frequent lack of blinding of participants and assessors across included trials.
