However, the frequently recommended flying start technique introduces a bias during parameter estimation. To correct this, two additional models (Estimated TC and Estimated FD) were proposed. To estimate model precision and sensitivity to detect the change, 31 basketball players executed multiple 30 m sprints. Athlete performance was simultaneously measured by a laser gun and timing gates positioned at 5, 10, 20, and 30 m. Short sprint parameters were estimated using a laser gun, representing the criterion measure, and five different timing gate models, representing the practical measures. Only the MSS parameter demonstrated a high agreement between the laser gun and timing gate models, using the percent mean absolute difference ((Formula presented.)) estimator ((Formula presented.) < 10%). The MSS parameter also showed the highest sensitivity, using the minimum detectable change estimator ((Formula presented.)), with an estimated (Formula presented.) < 17%. Interestingly, sensitivity was the highest for the No Correction model ((Formula presented.) < 7%). All other parameters and models demonstrated an unsatisfying level of sensitivity. Thus, sports practitioners should be cautious when using timing gates to estimate maximum acceleration indices and changes in their respective levels. © 2024 by the authors.}, keywords = {Adult; Adult; Male; Male; Humans; PERFORMANCE; PERFORMANCE; human; physiology; Young Adult; Young Adult; SPEED; parameter estimation; radar; POWER; POWER; Acceleration; Acceleration; Acceleration; Testing; SATELLITES; Basketball; Basketball; Basketball; Running; Running; Sports; Athletic Performance; Athletic Performance; sport; Athletes; athlete; athlete; athlete; Parameters estimation; Correction models; Exponential equations; Timing circuits; maximum acceleration; Gate models; Laser guns; Relative acceleration}, year = {2024}, eissn = {1424-8220} } @article{MTMT:34850857, title = {Association between dietary intake of creatine and female reproductive health: Evidence from NHANES 2017–2020}, url = {https://m2.mtmt.hu/api/publication/34850857}, author = {Ostojic, Sergej and Stea, T.H. and Ellery, S.J. and Smith-Ryan, A.E.}, doi = {10.1002/fsn3.4135}, journal-iso = {FOOD SCI NUTR}, journal = {FOOD SCIENCE AND NUTRITON}, unique-id = {34850857}, issn = {2048-7177}, abstract = {The hormonal changes in women influence creatine dynamics, emphasizing its potential importance during menstruation, pregnancy, postpartum, menopause, and postmenopause. Yet, limited research explores creatine's impact on female reproductive health at the population level. Our study investigated the relationship between dietary creatine intake and reproductive health indices in US women using data from the 2017–2020 National Health and Nutrition Examination Survey (NHANES). We extracted a dataset containing females aged 12 years and above who provided details about their reproductive health and dietary habits. Daily creatine intake was quantified as a relative amount (mg per kg body mass) and did not include creatine from dietary supplements and pharmacological agents. A daily requirement for dietary creatine for healthy women was employed to classify respondents into two separate subpopulations: (1) suboptimal intake of creatine (<13 mg per kg body mass per day) or (2) recommended intake (dietary creatine ≥ 13 mg per kg body mass per day). A total of 4522 female participants from the NHANES study (age 44.5 ± 20.5 years) provided data on their reproductive health and dietary intake. The average daily creatine intake for the group was 10.5 ± 10.8 mg per kg body mass. The odds ratio for having irregular periods in women consuming ≥13 mg of creatine per kg body mass daily (recommended intake) compared to those with suboptimal intake was 0.75 (95% CI, from 0.66 to 0.86), indicating a significant association between higher intake of dietary creatine and lower risk of oligomenorrhea (p <.001). Moreover, women consuming less than 13 mg of creatine per kg body mass faced an increased risk of fetal macrosomia (OR 1.26; p =.04), pelvic infection (OR 1.68; p =.01), hysterectomy (OR 1.42; p <.001), oophorectomy (OR 1.54; p <.001), and receiving hormone replacement therapy (OR 1.26; p =.02). Consuming a creatine-rich diet has been linked to lower risks of reproductive issues in US women aged 12 and above. Those consuming ≥13 mg of creatine per kg body mass daily showed notably lower risks of irregular menstrual periods, obstetric conditions, and pelvic pathology. Further studies are needed to confirm these potential benefits. © 2024 The Authors.

Creatine is often co-administered with glucose to improve its potency yet whether glucose boost the efficacy of creatine in long COVID remains currently unknown. In this report, we investigate the effects of 8-wk creatine intake with and without glucose on patient-reported outcomes, exercise tolerance, and tissue creatine levels in patients with long COVID. Fifteen male and female long COVID adult patients (age 39.7±16.0 y; 9 women) with moderate fatigue and at least one of additional long COVID-related symptoms volunteered to participate in this randomized controlled parallel-group interventional trial. All patients were allocated in a double-blind parallel-group design (1 : 1 : 1) to receive creatine (8 g of creatine monohydrate per day), a mixture of creatine and glucose (8 g of creatine monohydrate and 3 g of glucose per day), or placebo (3 g of glucose per day) t.i.d. during an 8-wk intervention interval. Two-way ANOVA with repeated measures (treatment vs. time interaction) revealed significant differences in changes in total creatine levels between the groups, showing an interaction effect at two brain locations (right precentral white matter F=34.740, p=0.008; partial η2=0.72; left paracentral grey matter F=19.243, p=0.019; partial η2=0.88), with creatine and creatine-glucose outcompeted placebo to elevate creatine levels at these two locations. Several long COVID symptoms (including body aches, breathing problems, difficulties concentrating, headache, and general malaise) were significantly reduced in creatine-glucose group at 8-wk follow-up (p≤0.05); the effect sizes for reducing body aches, difficulties concentrating, and headache were 1.33, 0.80, and 1.12, respectively, suggesting a large effect of creatine-glucose mixture for these outcomes. Our preliminary findings suggest that supplying exogenous creatine with glucose could be recommended as an effective procedure in replenishing brain creatine pool and alleviating long COVID features in this prevalent condition.}, keywords = {Brain; Brain; Brain; Adult; Adult; Female; Female; Middle Aged; Middle Aged; Male; Male; Humans; metabolism; MUSCLE; human; Double-Blind Method; Treatment Outcome; Treatment Outcome; controlled study; GLUCOSE; GLUCOSE; GLUCOSE; drug effect; randomized controlled trial; fatigue; fatigue; fatigue; Dietary Supplements; double blind procedure; creatine; creatine; creatine; Complication; Dietary supplement; COVID-19; coronavirus disease 2019; Severe acute respiratory syndrome coronavirus 2; SARS-CoV-2; post-acute COVID-19 syndrome; Long COVID; Long COVID}, year = {2024}, eissn = {1881-7742}, pages = {174-178}, orcid-numbers = {Betlehem, József/0000-0002-4526-4910; Ács, Pongrác/0000-0002-4999-7345; Ostojic, Sergej/0000-0002-7270-2541} } @misc{MTMT:34845904, title = {Investigating the relationships between endometriosis-related pelvic pain, pain self-efficacy, perceived stress, quality of life and physical activity}, url = {https://m2.mtmt.hu/api/publication/34845904}, author = {Kovács-Szabó, Zsófia and Hock, Márta}, unique-id = {34845904}, year = {2024} } @article{MTMT:34843304, title = {A szigetvári gyógyvíz hatásainak vizsgálata randomizált, kontrollált, kettős vak vizsgálattal}, url = {https://m2.mtmt.hu/api/publication/34843304}, author = {Hanzel, Adrienn and Horvát, K and Molics, Bálint and Berényi, Károly and Németh, Balázs and Szendi, Katalin and Varga, Cs}, journal-iso = {FIZIOTERÁPIA}, journal = {FIZIOTERÁPIA}, volume = {33}, unique-id = {34843304}, issn = {1789-4492}, year = {2024}, pages = {3-9}, orcid-numbers = {Berényi, Károly/0000-0001-5886-1311} } @article{MTMT:34840478, title = {Molecular hydrogen content of different dietary supplements}, url = {https://m2.mtmt.hu/api/publication/34840478}, author = {Ostojic, Sergej and Vranes, Milan}, doi = {10.17221/16/2024-CJFS}, journal-iso = {CZECH J FOOD SCI}, journal = {CZECH JOURNAL OF FOOD SCIENCES}, unique-id = {34840478}, issn = {1212-1800}, abstract = {The main goal of this study was to evaluate the concentration and release dynamics of molecular hydrogen (H-2 , dihydrogen) in dietary evaluate supplements and identify products that provide a biologically significant amount of dihydrogen suitable for human consumption. We examined ten commercial supplements marketed for their dihydrogen content, including slow-release capsules and tablets (4 products), effervescent powders and tablets (5 products), and canned ready-to-drink beverage (1 product). These products were acquired either through online purchases, from retail stores, or obtained free of charge directly from the manufacturers upon request. Dihydrogen concentration was measured using a highly sensitive Clark-type hydrogen microsensor with a detection limit 0.05 mu mol center dot L-1. Out of the ten products examined, only three (30.0%) exhibited dihydrogen levels surpassing the levels marketed as biologically relevant (500 mu mol center dot L-1), and one of these products (a canned ready-to-drink beverage) approached this level with a concentration of 439.2 mu mol center dot L-1. Interestingly, all slow-release capsules yielded negligible amounts of hydrogen (< 2 mu mol center dot L-1), while a slow-release tablet delivered 43.6 mu mol center dot L-1 of dihydrogen per single dose. The substantial variance in dihydrogen content among the assessed supplements holds significant implications for the general public, as high-potency products have the potential to provide up to 7 000 times more dihydrogen per single dosage compared to their low-potency counterparts.}, keywords = {Dihydrogen; Food supplements; Electrochemical}, year = {2024}, eissn = {1805-9317}, orcid-numbers = {Ostojic, Sergej/0000-0002-7270-2541} } @article{MTMT:34836452, title = {Comparative analysis of the quality of life regarding patients who underwent hip replacement in public versus private hospitals in Hungary}, url = {https://m2.mtmt.hu/api/publication/34836452}, author = {Kajos, Luca Fanni and Molics, Bálint and Than, Péter and Gőbel, Gyula and Elmer, Diána and Pónusz-Kovács, Dalma and Csákvári, Tímea and Kovács, Bettina and Horváth, Lilla Anita and Bódis, József and Boncz, Imre}, doi = {10.1038/s41598-024-60720-4}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {14}, unique-id = {34836452}, issn = {2045-2322}, abstract = {The study aimed to investigate the impact of hip replacement surgery on the quality of life and to compare the outcomes by sociodemographic and surgical data in Hungarian public and private hospitals.
