- MakaleAçık Erişim2026Scopus SJRQ3Chemical Profiling and Biological Activities of Methanol Extracts and Essential Oils From Ferulago Platycarpa Boiss. & Balansa (Endemic): Enzyme Inhibition, Antioxidant, and Antimicrobial Properties
Aygül, İmdat; Öz, Mehmet; Fidan, Muhammed Said; Baltacı, Cemalettin; Akmeşe, Osman; Sefalı, Abdurrahman
This study aimed to evaluate the phytochemical composition and biological activities of Ferulago platycarpa methanol extract (ME) and essential oil (EO). The EO was obtained via hydrodistillation and analyzed by GC-MS, revealing sesquiterpene hydrocarbons as the dominant class, with caryophyllene (65.8%) and α-pinene (9.65%) as the major constituents. The methanol extract was subjected to LC-MS/MS analysis, which identified eleven phenolic compounds, with chlorogenic acid as the most abundant. The extract showed significantly higher total phenolic (1196.22±11.64 mg GAE/100g) and antioxidant (1870.00±17.69 mg QEE/100g) contents compared to the ME. In vitro enzyme inhibition assays demonstrated that the methanol extract exhibited potent inhibitory activity against carbonic anhydrase II (CA-II, ICSO= 0.023 pg/mL), acetylcholinesterase (AChE, ICSO= 110 pg/mL), and butyrylcholinesterase (BChE, IC50= 390 pg/mL). In contrast, the EO showed higher inhibition against α-amylase (IC50= 5920±10.45 pg/mL) and BChE (IC50= 1.32±0.65 pg/mL), while its α-glucosidase showed no inhibition. Antioxidant assays indicated superior activity for the methanol extract compared to the EO. Furthermore, antimicrobial testing revealed that the EO demonstrated broader and more effective antimicrobial action, exhibiting lower MIC and MBC values against several bacterial and fungal strains. Collectively, these results highlight F. platycarpa as a valuable source of bioactive compounds with promising applications in antidiabetic, neuroprotective, antioxidant, and antimicrobial therapies.

Coşar, Mehmet; Şüküroğlu, Ebru Emine; Güngör, Kadir; Çolak, Murat
Ductile irons (spheroidal graphite cast irons, SGI) are widely used in automotive and energy systems due to their high strength, ductility, and excellent machinability. The casting quality of these alloys largely depends on the flow and filling behavior of the molten metal, namely its fluidity. In this study, the effects of pouring temperature, filling time, and metallurgical quality on the fluidity of GGG40 ductile iron were investigated through both experimental and numerical approaches. Experimental trials were conducted at pouring temperatures of 1350 °C, 1400 °C, and 1450 °C; metallurgical quality levels of 10%, 50%, and 90%; and filling times of 5 s and 10 s. The fluidity lengths were measured and statistically evaluated. The results revealed that increasing the pouring temperature and metallurgical quality significantly improved fluidity, while shorter filling times allowed the molten metal to travel longer distances before solidification. Modeling studies performed using a commercial casting simulation software showed strong correlation with the experimental data. Microstructural examinations indicated that higher pouring temperatures and improved metallurgical quality led to a more homogeneous distribution of graphite nodules and an increased ferrite fraction in the matrix. The findings provide valuable insights into the influence of process parameters on the fluidity behavior of ductile iron and offer critical design data for enhancing casting quality and productivity in industrial foundry applications.

Köse, Aslı
Aim: To evaluate the impact of nurses’ teamwork attitudes on their job performance. Method: A descriptive, correlational quantitative research design was employed. The sample consisted of 350 nurses who worked at a city hospital in Turkey and voluntarily participated. Data were analyzed using SPSS 25 to assess differences in teamwork attitudes and job performance according to nurses’ educational levels and years of professional experience. Results: The analysis revealed no statistically significant differences in teamwork attitudes or job performance based on educational level. The mean total score for teamwork attitudes was (3.27±0.80), while the mean total score for job performance was 3.25 (SD=0.82). A strong positive correlation was found between teamwork attitudes and job performance (r = 0.764; p < 0.001). A strong positive correlation was found between teamwork attitudes and job performance, with the former accounting for 58.4% of the variance in the latter. Conclusion: This study found that nurses working in a city hospital exhibited moderate attitudes toward teamwork and moderate job performance, and that these two measures were strongly positively correlated.

The post-activation performance enhancement (PAPE) effect has been widely studied; however, studies conducted under real-world conditions remain limited. Furthermore, investigations into how different conditioning activities (CAs) influence PAPE responses are also scarce. Therefore, this study investigates the acute effects of high-intensity barbell hip thrust (BHT) and back squat (BS) exercises, performed after a soccer-specific warm-up (Wup), on physical performance in soccer players. Seventeen male amateur soccer players participated in the study (mean age: 22.29 ± 3.60 years; height: 1.78 ± 0.06 m; body weight: 73.18 ± 8.44 kg). Participants attended 5 experimental sessions. In the first session, after anthropometric assessments, participants were familiarized with the exercises and tests. In the second session, one-repetition maximum (1RM) was tested for BS and HT exercises. In the following three sessions, two PAPE protocols and one traditional (TRAD) protocol were performed in a randomized order. In the TRAD protocol, players performed physical performance tests including countermovement jump (CMJ), 10-m and 30-m sprint, and zigzag agility 16 minutes after a soccer-specific Wup. In the PAPE protocols, players performed CAs (e.g., hip thrust or back squat) at 85% of 1RM for 2 sets of 3 repetitions following a soccer-specific Wup, and completed the tests 8 minutes later. Results from the linear mixed-effects models revealed no significant effect of protocol on any performance variable, including CMJ (F(2,32) = 1.554, p = 0.227), 10 m sprint (F(2,32) = 0.242, p = 0.786), 30 m sprint (F(2,32) = 0.453, p = 0.640), and change of direction (COD) performance (F(2,32) = 0.946, p = 0.399). Marginal R² values indicated that the protocol explained only a minimal proportion of variance in performance outcomes (0.005–0.030), whereas conditional R² and ICC values suggested that between-participant differences accounted for a substantial proportion of variance, particularly for CMJ and 30 m sprint performance. Bonferroni-adjusted pairwise comparisons further showed no significant differences between PAPEBHT, PAPEBS, and TRAD protocols for CMJ, 10 m sprint, 30 m sprint, or COD performance (all p > 0.05). In conclusion, neither PAPE protocol performed after a soccer-specific warm-up significantly enhanced or impaired subsequent CMJ, sprint, or COD performance compared with the traditional warm-up. These findings suggest that adding PAPEBHT or PAPEBS protocols after a soccer-specific warm-up may maintain subsequent performance without inducing measurable decrements; however, their ergogenic effectiveness may depend on individual factors such as players’ strength levels, recovery capacity, training status, and physical characteristics.

Objectives This study was conducted to evaluate the effect of ShotBlocker use on pain levels during needle-related procedures in adults. Design Systematic review and meta-analysis. Data sources Studies were searched in the PubMed, Web of Science, ScienceDirect, Google Scholar, and Higher Education Council (YÖK) Thesis Center databases without any year restrictions. Review/Analysis methods The search and study selection were conducted in accordance with the PRISMA 2020 guidelines, and 18 studies meeting the inclusion criteria were included in the analysis. Data extraction and methodological quality assessment were performed using the Joanna Briggs Institute (JBI) critical appraisal tools. Findings were evaluated using meta-analysis and narrative synthesis methods. Results In this systematic review and meta-analysis, ShotBlocker was found to be effective in reducing pain levels in adults (SMD = −1,011; 95% CI: −1.390 to −0.631; Z = −5,221; p < .001; I² = 91.4%). However, substantial heterogeneity was observed among the included studies (I² = 91.4%). Conclusions This study demonstrates that ShotBlocker may be an effective nonpharmacological method for reducing pain levels during needle-related procedures in adults. However, the results should be interpreted with caution because of the substantial heterogeneity among the included studies.

Hasozdemir, Kursat; Meral, Mert; Kahraman, Muhammet Mustafa
Accurate near-real-time granulometry is critical for optimizing energy efficiency in comminution circuits, yet standard optical monitoring systems fail under the harsh conditions of industrial mining. High conveyor velocities induce motion blur, while heavy dust loads occlude particle boundaries, leading to severe under-counting of fine fractions and an overestimation of product coarseness. This paper proposes a novel tracking framework to overcome these limitations. The method integrates a five-frame temporal rolling buffer with a multi-stream augmentation architecture that decouples motion and texture features. Experimental validation on the feed of a secondary conical crusher at an operational facility demonstrates that the proposed framework recovers significant particle data lost by baseline models, correcting the measured D80 and D50 values of the crushed material. This correction reveals a finer true load, enabling more precise closed-loop control of crusher settings and reducing unnecessary energy consumption.

Şahin, Nagehan; Şan, Murat; Kankal, Murat
The impact of climate change on extreme rainfall regimes requires a reassessment of the design processes of traditional hydrological structures. For this purpose, conducting an in-depth analysis of the nonstationary nature of extreme rainfall in regions with complex topography and climate is of great importance. This study examines the stationary and nonstationary states of standard duration (5 min–24 h) annual maximum rainfall data across Türkiye. For this purpose, the intensity-duration-frequency relationship was analyzed using data at 100 homogeneous stations during 1980–2020. The analyses were performed using the generalized extreme value (GEV) distribution with eight linear and non linear location and scale parameters, based on stationary and nonstationary models. Time was included as a covariate in nonstationary models. The corrected akaike information criterion and likelihood ratio test were used to select the appropriate GEV distribution. Findings indicate that stationarity is generally dominant, but nonstationarity is relatively higher in a nonlinear manner in cold climates and complex topography. The effect of location and scale parameters was found to be individual in the short duration and combined in the long duration. It was observed that nonstationarity was relatively higher in complex topography than in flatter regions up to 8 h. Still, the diversity of nonlinear models decreased over the long duration. In conclusion, this study emphasizes the need to consider nonstationary approaches in designing hydrological structures, especially in climate change.

Top, Yener
Wood is a renewable material, and advancements in machinery have made it possible to produce wood-based products in large quantities. This has led to environmental problems, which in turn have increased consumers’ environmental concern. This concern has caused consumers to prefer environmental-friendly products. Alongside green products and green marketing, greenwashing practices, which are not actually green but exploit consumer sensitivity, have also become widespread. These deceptive claims confuse consumers and provide an unfair competitive advantage against genuinely environmentally friendly products. Polyvinyl chloride (PVC) windows, which can be used as a substitute for wood windows, were chosen as a research focus, and the greenwashing practices of enterprises manufacturing PVC window were investigated. The research was conducted using deductive content analysis. The corporate websites of the enterprises were examined in terms of greenwashing. Artificial intelligence was used, but identified greenwashing types were checked by the researcher. The study found that PVC window manufacturers most frequently resorted to greenwashing involving no proof, vagueness, and hidden trade-off approaches. Greenwashing types were also examined by topics, revealing that “general environmental benefits” is the most common type.

Eker, Çiğdem Saydam; Yücel, Cem; Kaygusuz, Abdullah; Aydınçakır, Emre; Jeong, Youn-Joong; Yılmazer, Sinan; Sünnetçi, Kadir
Detrital zircons are crucial stand-ins for the history of continental crust growth and disintegration, as well as the dispersal and assembly of supercontinents. Detrital zircons are effectively used to assess crustal history because sediments transport zircons from source rocks that are no longer at the surface. This study presents detailed Lu-Hf isotopic, U-Pb geochronological analyses of zircon, Sr-Nd isotopic analyses and whole-rock geochemical results from sandstone, volcanically derived sandstone and tuff samples of the Campanian-aged Bozbent Member in the Eastern Pontide Orogen belt of the Sakarya Zone. Sedimentological analyses show that the Bozbent Member was transported and deposited by turbidite currents, while petrographic and geochemical analyses show that the sandstones range from greywacke to litharenite. In this study, U-Pb ages of detrital zircon obtained from Campanian sandstones are presented, along with in situ εHf data. A magmatic origin is indicated by the majority of zircons' oscillatory zoning and by Th/U ratios ranging from 0.2 to 1.5. The ages of detrital zircons range from 2819 to 78 Ma, with most of these zircons being Proterozoic (552–994 Ma). Proterozoic zircons are detrital zircons associated with the Gondwana and the African Craton. The whole-rock geochemical data and Sr-Nd isotope compositions of the sandstones are consistent with local Carboniferous felsic plutons, Jurassic mafic and felsic plutons, Jurassic volcanic rocks, Jurassic clastic rocks and clastic material from Precambrian recycled sediments. It was calculated that more than 90% of the detrital zircons had crystallisation ages older than their depositional ages (CA-DA > 150 Ma, indicative of an extensional basin model). These findings indicate that the Campanian-aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore-arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

In this study, the enzyme inhibitory, antibacterial, and anticancer activities of a phthalonitrile derivative and its metal phthalocyanines (Pcs; indium, zinc, copper, cobalt, and manganese; 1–6) were investigated. The cobalt and manganese Pcs were synthesized for the first time in this study. The inhibitory activities of the symmetric Pcs, which were expected to interact with acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) via their 4-(isopropylbenzyl)oxy substituents through host–guest interactions, were investigated. More selective inhibition of AChE than BChE was observed for these compounds. For AChE, CoPc was identified as the most potent inhibitor (IC50 = 14.81 nM), whereas for BChE, InPc was identified as the most potent inhibitor (IC50 = 56.35 nM). The Ki values indicated that most compounds exhibited competitive inhibition; copper phthalocyanine (CuPc) showed particularly strong inhibition against AChE (Ki = 3.08 nM ± 1.12), whereas the lowest Ki value against BChE was observed for MnPc (Ki = 25.98 ± 1.97 nM). Most compounds exhibited competitive inhibition; however, CuPc showed competitive inhibition toward AChE but a noncompetitive inhibition pattern toward BChE. Dual inhibition of AChE and BChE by these compounds may be promising for addressing cholinergic deficits associated with Alzheimer’s disease. In addition, the acceptability of compounds 1–6 with respect to pharmacological drug-likeness criteria was assessed based on predicted absorption, distribution, metabolism, excretion (ADME) outcomes. In antibacterial tests, varying levels of inhibition were observed against selected bacterial strains. In anticancer assays, all compounds exhibited high cytotoxicity against the MCF-7 breast cancer cell line. Higher antiproliferative activity was observed for CuPc than for the other compounds. Morphological changes were induced in cancer cells by CuPc and MnPc. Overall, these compounds may have potential as enzyme inhibitors and as antibacterial and anticancer agents.

İncele - MakaleYalnız künye2026Scopus SJRQ2Arctic governance through discourse: Arctic and Arctic council observer states
Limon, Onur; Gürdal Limon, Elif
This article examines how Arctic governance is discursively constituted through national Arctic policy and strategy documents and how these discursive constructions differentiate governance roles between Arctic states and Arctic Council observer states. Rather than treating national strategies as neutral policy instruments, the study conceptualizes them as political texts that articulate authority, responsibility, and legitimacy within an asymmetrical governance system. Methodologically, the article employs qualitative discourse analysis of the most recent official Arctic strategies of eight Arctic states and twelve observer states. Using MAXQDA (version 24), the analysis is organized around six thematic domains: security policy; climate change and environment; international cooperation; resource management; Indigenous peoples and rights; and economic development and sustainability. The findings reveal a high degree of discursive convergence across both actor groups, particularly around climate change, sustainability, environmental protection, and cooperation. However, this convergence does not indicate substantive policy alignment or egalitarian governance. Arctic states frame governance through narratives of sovereignty, stewardship, and regulatory responsibility, while observer states construct legitimacy through scientific contribution, multilateralism, and normative alignment. The article argues that discursive convergence can function as a kind of governance infrastructure that enables participation while tending to stabilize asymmetrical authority.

Yapıcı, İsmail; Gülçin, İlhami
Phenolic compounds are versatile bioactive molecules, particularly in food applications. In this study, the antioxidant capacity of Shogaol, a member of the phenolic class, was evaluated using several methods. Additionally, its inhibitory effects on human carbonic anhydrase I and II (hCA I and II), acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-glycosidase, and α-amylase enzymes, as well as its antiproliferative effects on A-549 lung cancer, HT-29 colon cancer, MCF-7 and MDA-MB-453 breast cancer cell lines, and the 3T3-L1 mouse fibroblast normal cell line, were investigated. To determine the antioxidant capacity of Shogaol, DPPH and ABTS radical scavenging assays, as well as Cu²⁺, Fe³⁺, and FRAP reduction methods, were employed. Its inhibitory effects on hCA I and II, AChE, BChE, α-glycosidase, and α-amylase enzymes were examined. Furthermore, cell counting was performed using the TBE method, and cell viability was measured with the XTT assay to assess the antiproliferative effects of Shogaol on A-549, HT-29, MCF-7, MDA-MB-453, and 3T3-L1 cell lines. Shogaol demonstrated higher antioxidant capacity than BHA, BHT, and Trolox in the FRAP assay (60 µg/mL), higher than BHT in the DPPH scavenging assay, and higher than Trolox in the ABTS, Cu²⁺, and Fe³⁺ reduction assays. Shogaol also exhibited significant inhibitory effects against hCA I, hCA II, AChE, BChE, and α-glycosidase, with IC₅₀ values of 75.91, 47.04, 37.44, 24.11, and 35.72 nM, respectively. Moreover, Shogaol showed a more potent antiproliferative effect than the standard chemotherapeutic drug Carboplatin in A-549 lung cancer and HT-29 colon cancer cell lines, and greater efficacy than Docetaxel in the MCF-7 breast cancer cell line.

Nonuterine leiomyosarcoma (NU-LMS) is a rare and biologically distinct subtype of soft tissue sarcoma (STS) with clinical behavior differing from that of uterine leiomyosarcoma. In advanced or metastatic STS, immunotherapy has demonstrated only modest activity, and chemotherapy remains the cornerstone of treatment. However, there is a persistent unmet need for more effective and better-tolerated options in this population. This multicenter, retrospective study included 150 patients with histologically confirmed metastatic NU-LMS who received first-line doxorubicin-ifosfamide (AI) or gemcitabine-docetaxel (GD) at 26 oncology centers in Turkey between 2010 and 2024. The primary endpoint was overall survival (OS). Survival was analyzed using Kaplan-Meier estimates and Cox proportional hazards models. Of 150 patients, 79 received AI and 71 received GD. Median OS for the entire cohort was 21.0 months. Median OS was 22.0 months with AI and 19.1 months with GD (p = .18), median progression-free survival was 7.3 versus 6.1 months (p = .66), and overall response rate was 25.3% versus 29.6% (p = .58), indicating no statistically significant differences in efficacy between the two regimens. Hematologic toxicities were less frequent with GD. AI and GD demonstrated comparable efficacy as first-line regimens for advanced or metastatic NU-LMS, with fewer hematologic toxicities observed for GD. Tumor location may have prognostic implications. These findings support individualized treatment selection and highlight the need for prospective studies in this rare and understudied sarcoma subtype, while the recent LMS-04 trial underscores the importance of future comparisons with doxorubicin-trabectedin to further refine first-line strategies in LMS.

Background/aim: Invasive mechanical ventilation (IMV) is a fundamental intervention for patients with respiratory failure in intensive care units (ICUs). This nationwide, multicenter point-prevalence study aimed to describe current mechanical ventilation mode preferences (conventional, adaptive, and biphasic) in Turkish ICUs and to report associated clinical outcomes descriptively, without assessing causal relationships. Materials and methods: A nationwide, multicenter point-prevalence study was conducted on 17 April 2024 and included adult patients (>= 18 years) who had been receiving IMV for more than 24 h. Data on patient demographics, ventilation mode distribution, ventilatory parameters, and descriptive clinical outcomes on day 28 (weaning status, tracheostomy, and mortality) were recorded without comparative outcome analysis. Results: A total of 426 patients were included. Conventional modes were used in 84.5% of patients, adaptive modes in 10.6%, and biphasic modes in 4.9%. Synchronized intermittent mandatory ventilation (SIMV) was the most commonly used conventional mode. The primary indication for IMV was acute respiratory failure (61%), with pneumonia being the leading cause. Among the 350 orotracheally intubated patients, 25.6% were in the weaning phase on the study day. A total of 59 (16.9%) patients were extubated, 150 (42.9%) underwent tracheostomy, and 64 (18.2%) remained intubated on day 28. Overall, 185 (43.4%) patients died during their ICU stay, 152 (35.7%) remained in the ICU, and 89 (20.9%) were successfully discharged from the ICU. Conclusion: Conventional ventilation modes, particularly SIMV, were more commonly used in Turkish intensive care units (ICUs), whereas adaptive modes were less frequently applied. These patterns may reflect factors such as clinician familiarity, institutional practices, and equipment availability rather than definitive preferences. Although the impact of ventilation modes on clinical outcomes was not comparatively evaluated in this study, the choice of ventilation mode may still influence patient outcomes. Therefore, further prospective and comparative studies are warranted to better elucidate this relationship.

Providing ethical care for people living with dementia is essential for safeguarding their rights, dignity, and well-being. However, ethical decision-making in dementia care is complex, often involving tensions between competing moral claims such as autonomy, beneficence, nonmaleficence, justice, and non-discrimination. This scoping review aimed to map and describe the ethical principles, related normative considerations, and ethical frameworks discussed in the scientific literature on dementia care, and to identify how these have been conceptualized. Following the methodological guidance of Arksey and O'Malley (2005), Levac et al. (2010), and Peters et al. (2021, 2022), a comprehensive search across five databases (Web of Science, Scopus, CINAHL, Medline/PubMed, and PsycInfo) identified peer-reviewed papers published in English. In total, 388 papers published between 1981 and 2024 were included. The results revealed a wide range of ethical principles and related normative considerations frequently cited in the literature, although they were typically discussed in an isolated way without reference to other principles or broader ethical frameworks. In contrast, ethical frameworks were mentioned far less often, and when they were, they mostly reflected traditional approaches such as principlism. Four gaps were identified: the plurality of ethical frameworks and limited conceptual integration underpinning dementia care research and practice; insufficient attention to ethnic and socioeconomic diversity among people living with dementia; limited consideration of diverse care settings and geographical regions; and the limited inclusion of people living with dementia themselves in the studies reviewed. These findings underscore the need for conceptually integrative, inclusive, and context-sensitive approaches to dementia care ethics that can better inform both ethical reflection and care practices.

The magnetic moments and electric quadrupole moments of the B-5 isotopes were calculated using different nuclear interactions and sets of effective charges. Instead of relying on core polarization, the effective charges were adopted through a microscopic theoretical approach. The one-body density matrix (OBDM) elements for these isotopes were calculated using the NuShellX@MSU code. The calculations were carried out within the shell model framework, using both the p- and psd-model spaces (MS). These model spaces were selected for nuclei with proton number Z = 5 and neutron number N > 3. The theoretical results for magnetic and quadrupole moments were compared with available experimental data. Theoretical magnetic moments of the B-8,B-10,B-11,B-12,B-13 isotopes showed good agreement with experiment when using the p-MS with the pwt interaction, and the psd-MS with the psdmwk interaction. Similarly, the theoretical electric quadrupole moments reasonably well with the experimental values when using the p-MS with the pkuo interaction, and the psd-MS with the psdmwk interaction.

Background Inspiratory muscle training (IMT) has been shown to enhance respiratory efficiency, postural stabilization, and neuromuscular coordination in athletic populations. However, its effects in precision sports such as air pistol shooting remain insufficiently explored. This study investigated the impact of a 4-week IMT program on respiratory muscle strength, explosive lower-limb performance, reaction time, and shooting accuracy in competitive air pistol athletes. Methods Twenty trained male air pistol athletes (age 18-35 years) were randomly assigned to an IMT group (n = 10) or a control group (n = 10). The IMT group performed supervised inspiratory muscle training twice daily (30 breaths/session), six days per week, for four weeks, using a threshold-loading device set initially at 40% of maximal inspiratory pressure (MIP), with progressive overload applied weekly. Both groups maintained their regular shooting training routines. Pre- and post-intervention assessments included countermovement jump (CMJ) and squat jump (SJ) performance (OptoJump), visual and auditory reaction time (Cognitech), and shooting performance evaluated via the SCATT system. A two-way repeated-measures ANOVA (group & times; time) was used for statistical analysis. Results Significant group & times; time interactions were observed for CMJ height (p < 0.001, eta & sup2;p = 0.618), CMJ power (p = 0.007, eta & sup2;p = 0.345), SJ height (p = 0.050, eta & sup2;p = 0.184), and SJ power (p = 0.050, eta & sup2;p = 0.181), indicating meaningful improvements in explosive performance in the IMT group. Shooting accuracy demonstrated a large and statistically significant interaction effect (p < 0.001, eta & sup2;p = 0.532), with substantial improvement observed only in the IMT group. Reaction time variables showed favourable but non-significant trends (p > 0.05). Conclusion A short-term IMT intervention significantly enhanced lower-limb explosive performance and shooting accuracy in competitive air pistol athletes without altering overall training load. These findings suggest that IMT may represent an effective, low-cost adjunct strategy to improve neuromuscular stability and fine-motor precision in precision-sport athletes.
