  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.

  Game-based and individualized movement training improves physiological and motor outcomes in young adults with autism spectrum disorder: an experimental study from Türkiye

  Aydın, Ahmet Serhat; Söyler, Mehmet; Zileli, Raif; Halmatov, Medera; Gürkan, Alper Cenk; Akcan, İbrahim Orkun; Yılmaz, Coşkun

  Background: This study aims to examine the effects of game-based and individualized movement training (GBIMT) program on physiological (body weight, body fat percentage, BMI) and motor outcomes (balance, reaction time, motor speed) in young adults diagnosed with autism spectrum disorder (ASD). Methods: An experimental design with pre-test–post-test control groups was used in the study. A total of 20 participants (10 in the experimental group, 10 in the control group) with a mean age of 22.2 ± 4.8 years were monitored for eight weeks. The experimental group participated in GBIMT sessions for 60 min per day, two days per week, while the control group continued their usual educational routines. Body composition (InBody 270 Body Composition Analyzer, model Plus 270, South Korea), balance (TechnoGym, Cesena, Italy), reaction time (BlazePod Ltd., Israel), and motor speed (Computerized Tapping Test, Neurosoft Inc., USA) parameters were used as measurements. Results: Repeated measures ANOVA results indicated a significant reduction in body weight in terms of the experimental group (p = 0.014, η² = 0.289). Large effect sizes were observed for body fat percentage and BMI; however, the group × time interactions were not found to be statistically significant. A significant improvement was observed in the motor speed parameter within the experimental group (p = 0.032, η² = 0.231). Reaction time decreased by 9.8%, although the group × time interaction stayed within the significance limit (p = 0.063). A trend toward improvement was observed in balance parameters; however, no statistically significant difference was found. Conclusion: The findings indicate that GBIMT produced significant improvements in body composition and motor speed after implementing for eight weeks, and also showed a strong tendency to affect reaction time. As a controlled experimental study conducted in Türkiye, this research offers a unique contribution to the literature by demonstrating the effects of game-based and individualized movement programs on both physiological and motor outcomes in individuals with ASD.

  Acute effects of inspiratory muscle warm-up on muscular performance and pulmonary function in natural male bodybuilders

  Ceylan, Tülay; Ceylan, Levent; Yılmaz, Coşkun; Badau, Adela; Küçük, Hamza

  Background: Inspiratory muscle warm-up (IWU) has been hypothesized to enhance athletic performance by pre-activating respiratory muscles; however, evidence in professional natural male bodybuilders is scarce. The present study investigated the acute effects of IWU on One-Repetition maximum (1RM) bench press performance and pulmonary function. Methods: The present randomized controlled experimental study comprised 20 male athletes with an average training experience of 3.21 ± 1.44 years, who trained for more than 5 h per week and had participated in national or international competitions. At the commencement of the study, all participants underwent a series of pulmonary function tests (PFTs), measurements of maximal inspiratory and expiratory pressures (MIP and MEP), and a 1RM test. Following the initial assessments, which were conducted seventy-two hours prior, participants were randomly assigned to either the IWU group (n = 10) or the control (CON) group (n = 10). While the IWU group performed both inspiratory muscle warm-up and standard exercise warm-up, the CON group performed only the standard warm-up. Subsequent to the execution of the warm-up protocols, both groups were subjected to re-evaluation through the means of the 1RM test and respiratory parameter measurements. Results: The IWU group demonstrated a 5.96% greater enhancement in 1RM performance in comparison to the control group (p < 0.001). Furthermore, significant increases were observed in FVC, FEV1, and FEV1/FVC following IWU, with improvements of 2.57%, 2.44%, and 2.65%, respectively (p < 0.001). Furthermore, an additional 2.39% enhancement in MEP was identified in favour of the IWU group (p = 0.008). The alterations in MIP and PEF exhibited by the two groups were analogous, with no statistically significant disparities observed (p > 0.05). Conclusions: The present study has demonstrated that IWU has the capacity to rapidly enhance maximal strength and respiratory function in professional bodybuilders. Consequently, IWU can be advocated as an efficacious warm-up technique to augment exercise performance in bodybuilding athletes. Trial registration: This trial was registered at ClinicalTrials.gov under the title “Acute effects of inspiratory muscle warmup on muscular performance and pulmonary function in natural bodybuilders’’. ClinicalTrials.gov NCT07390149, Date 18012026. (Retrospectively)

  Psychometric properties of the Turkish version of the VARK learning style inventory for athletes

  Türker, Üstün; Somoğlu, Mustafa Barış; Koç, Mustafa; Bostancı, Özgür

  Background: Understanding how athletes learn and recognizing their learning preferences are important cognitive and sensory components that may support effective instructional planning in sport settings. This study aimed to adapt the VARK Learning Style Inventory for Athletes (Visual, Aural, Read/Write, and Kinesthetic modalities) into Turkish and to evaluate its psychometric properties. Methods: A total of 854 licensed athletes from individual and team sports in Türkiye participated in the study. The Turkish version of the VARK Learning Style Inventory for Athletes was administered using a paper-based format. Data were analyzed using IBM SPSS Statistics (v26) and LISREL (v8.80). Construct validity was examined using a Multitrait–Multimethod Confirmatory Factor Analysis (MTMM-CFA) approach with a correlated trait–correlated uniqueness (CTCU) specification, while reliability was assessed using internal consistency and test–retest procedures. Results: The MTMM-CFA supported the four-factor structure of the inventory, indicating an acceptable model fit and strong associations among the learning style dimensions, consistent with a multimodal learning preference profile. Internal consistency analyses yielded Kuder–Richardson 20 (KR-20) coefficients ranging from 0.574 to 0.623 across subscales, reflecting moderate reliability. Conclusions: The findings suggest that the Turkish version of the VARK Learning Style Inventory for Athletes demonstrates acceptable psychometric properties, with evidence of construct validity and moderate internal consistency. While the results support its use for assessing learning preferences among Turkish athletes, further research across different sport disciplines and age groups is recommended to strengthen there liability evidence and practical applicability. Overall, the study contributes to measurement practices in sport and exercise sciences by providing a culturally adapted instrument for examining athletes’ learning preferences.

  Effects of inspiratory muscle training combined with circadian rhythm-based running programs in male children football players

  Konca, Erkan; Yilmaz, Coşkun; Saç, Ajlan; Dal, Suzan; Halmatov, Medera; Akıllıoğlu, Osman; Bayrakdaroğlu, Serdar

  Background: Inspiratory muscle training (IMT) has been suggested to improve respiratory function and physical performance; however, evidence in preadolescent athletes remains limited. This study examined whether adding IMT to circadian rhythm–based running programs would enhance functional and pulmonary outcomes in preadolescent male football players with at least two years of regular football training experience. Methods: Seventy-five boys aged 10–12 years were categorized into morning-, intermediate-, or evening-type groups based on Morningness–Eveningness Scale for Children (MESC) scores, and each chronotype group was assigned to its corresponding running protocol with or without IMT. Over six weeks, participants completed circadian rhythm–based running sessions, and IMT groups performed graded-load IMT. Pre- and post-intervention assessments included agility, six-minute walk test (6MWT), pulmonary function (FVC, FEV₁, FEV₁/FVC), and respiratory muscle strength (MIP, MEP). Results: Agility and 6MWT performance improved most in the morning running + IMT group compared with evening running + IMT and running-only groups (p < 0.001). FVC and FEV₁ increased in both IMT groups, though gains were modest and smaller in the running-only group. Improvements in MIP and MEP did not differ significantly between groups. Conclusion: Combining IMT with morning running produced the greatest improvements in agility and functional performance, while pulmonary gains were moderate and respiratory muscle strength changes were comparable across groups. IMT may provide additional benefit when integrated into chronotype-aligned morning training in preadolescent football players.

  Match success in football: insights from raw and possession-normalized key performance indicators in the Turkish professional league

  Sever, Ozan; Öncü, Çağdaş; Öztaşyonar, Yunus; Aksoy, Ömer; Bayrakdaroğlu, Serdar

  Background: Match-performance indicators are widely used to explain success in football; however, traditional analyses based solely on absolute key performance indicators (KPIs) may overlook contextual factors such as ball possession and phase of play. This study aimed to examine match-performance indicators associated with winning in Turkish professional football using two complementary approaches: a raw KPI model based on absolute match actions and a possession- and phase-of-play–normalized KPI model accounting for contextual opportunity. Methodology: Match data were obtained from a validated event-based database covering six consecutive seasons, yielding 2,728 team observations from 1,364 win–loss matches. Descriptive comparisons between winning and losing teams were conducted, followed by multivariate binary logistic regression analyses to identify performance indicators independently associated with match success under both modeling approaches. Results: At the descriptive level, winning teams demonstrated higher values for shots, shots on target, accurate passes, opponent-half accurate passes, accurate crosses (%), and opponent-half accurate passes (%), whereas total possession and total passes did not differ significantly between groups. In terms of disciplinary indicators, losing teams received significantly more yellow and red cards, whereas fouls committed were significantly higher in winning teams (p = 0.014). However, the normalized indicator (fouls committed per out-of-possession) did not differ significantly between groups. In the raw KPI model, positive predictors of match success included shots on target (OR = 1.58), accurate crosses (OR = 1.10), opponent-half accurate passes (OR = 1.01), and fouls committed (OR = 1.04). Negative predictors were total crosses (OR = 0.92), yellow cards (OR = 0.89), and red cards (OR = 0.49). In the possession-normalized model, significant positive predictors were shots on target per possession, accurate crosses per possession, and fouls committed per out-of-possession. Significant negative predictors included crosses per possession, accurate crosses (%), yellow cards per out-of-possession, and red cards per out-of-possession. Conclusions: The findings indicate that combining absolute performance indicators with context-sensitive normalized metrics may provide a more comprehensive perspective on match success in football. Offensive efficiency and disciplinary control emerged as key correlates of winning, particularly when evaluated relative to possession and phase-of-play contexts. These findings suggest the potential value of integrating contextualized performance analysis into match evaluation and performance analysis frameworks.

  Warm up with music and visual feedback can effect Wingate performance in futsal players

  Bayrakdaroglu, Serdar; Eken, Oezgur; Yagin, Fatma Hilal; Bayer, Ramazan; Gulu, Mehmet; Akyildiz, Zeki; Nobari, Hadi

  Purpose: Visual feedback and music while warm up may help elicit peak performance, but its effect during the Wingate anaerobic test (WAnT) in futsal players is unexplored. Therefore, the aim of this study was to examine the effects of music and visual stimulus on WAnT performance in futsal players. Methods: The study included 17 young male futsal players (age, 21.53 +/- 1.32 years; height, 177.59 +/- 5.75 cm; 73.71 +/- 9.31 kg; BMI 23.342 +/- .47). The WAnT was administered using three distinct protocols: with music (M), without music (NM), and with music and visual feedback (MV) following a 10-min warm-up at 72-h intervals. After WAnT, the following parameters were evaluated: (a) peak power output: PPO (W), (b) relative peak power output: RPPO (W/kg), (c) mean power output: MPO (W), (d) relative mean power output: RMPO (W/kg), (e) fatigue index: FI (%), and (f) minimum power output MIPO (W). Results: MV indicated that futsal players' WAnT values, including PPO, RPPO, MPO, RMPO, and MIPO improved more than with other protocols (p < 0.05). However, there was no significant difference between protocols for FI (%) WAnT values (p > 0.05). Conclusions: Listening to music and watching visual feedback while warm up before performing WAnT performance suggest to coaches and futsal players.
