The acceleration–velocity profile (AVP) provides a simple summary of short sprint performance using two parameters: MSS and MAC, which are useful for simplifying descriptions of sprint performance, comparison between athletes and groups of athletes, and estimating changes in performance over time or due to training intervention. However, discrete testing poses logistical challenges and defines an athlete’s AVP exclusively from the performance achieved in an isolated testing environment. Recently, an in situ AVP (velocity–acceleration method) was proposed to estimate kinematic parameters from velocity and acceleration data obtained via global or local positioning systems (GPS/LPS) over multiple training sessions, plausibly improving the time efficiency of sprint monitoring and increasing the sample size that defines the athlete’s AVP. However, the validity and sensitivity of estimates derived from the velocity–acceleration method in relation to changes in criterion scores remain elusive. To assess the concurrent validity and sensitivity of kinematic measures from the velocity–acceleration method, 31 elite youth basketball athletes (23 males and 8 females) completed two maximal effort 30 m sprint trials. Performance was simultaneously measured by a laser gun and an LPS (Kinexon), with kinematic parameters estimated using the time–velocity and velocity–acceleration methods. Agreement (%Bias) between laser gun and LPS-derived estimates was within the practically significant magnitude (±5%), while confidence intervals for the percentage mean absolute difference (%MAD) overlapped practical significance for TAU, MAC, and PMAX using the velocity–acceleration method. Only the MSS parameter showed a sensitivity (%MDC95) within practical significance (<5%), with all other parameters showing unsatisfactory sensitivity (>10%) for both the time–velocity and velocity–acceleration methods. Thus, sports practitioners may be confident in the concurrent validity and sensitivity of MSS estimates derived in situ using the velocity–acceleration method, while caution should be applied when using this method to infer an athlete’s maximal acceleration capabilities.}, year = {2024}, eissn = {1424-8220}, orcid-numbers = {Jovanović, Mladen/0000-0002-4013-6530; Cabarkapa, Dimitrije/0000-0001-9912-3251; Trunić, Nenad/0000-0001-5339-7695; Banković, Vladimir/0009-0000-5133-4383} } @article{MTMT:35263372, title = {PERFORMANCE DIAGNOSTIC EXAMINATION OF WOMEN'S HANDBALL PLAYERS}, url = {https://m2.mtmt.hu/api/publication/35263372}, author = {Derkács, Evelin Andrea and Melczer, Csaba and Nagy, Dóra and Tardi, Péter and Ihász, Ferenc and Molics, Bálint and Boncz, Imre and Kajos, Luca Fanni and Prémusz, Viktória}, doi = {10.1016/j.jval.2024.03.156}, journal-iso = {VALUE HEALTH}, journal = {VALUE IN HEALTH}, volume = {27}, unique-id = {35263372}, issn = {1098-3015}, year = {2024}, eissn = {1524-4733}, pages = {S29}, orcid-numbers = {Melczer, Csaba/0000-0002-8197-0572; Tardi, Péter/0000-0002-5091-7373; Ihász, Ferenc/0000-0003-0213-2237; Boncz, Imre/0000-0003-3699-6236; Kajos, Luca Fanni/0000-0002-0574-5787; Prémusz, Viktória/0000-0002-4059-104X} } @article{MTMT:35263306, title = {COMPARATIVE EXAMINATION OF PERFORMANCE METRICS IN FOOTBALL AND HANDBALL PLAYERS WITHIN CONTROLLED LABORATORY ENVIRONMENTS}, url = {https://m2.mtmt.hu/api/publication/35263306}, author = {Derkács, Evelin Andrea and Melczer, Csaba and Nagy, Dóra and Makai, Alexandra and Pótó, Zsuzsanna and Molics, Bálint and Boncz, Imre and Kajos, Luca Fanni and Ács, Pongrác}, journal-iso = {VALUE HEALTH}, journal = {VALUE IN HEALTH}, volume = {27}, unique-id = {35263306}, issn = {1098-3015}, year = {2024}, eissn = {1524-4733}, pages = {S45-S45}, orcid-numbers = {Melczer, Csaba/0000-0002-8197-0572; Makai, Alexandra/0000-0002-1907-120X; Pótó, Zsuzsanna/0000-0002-5460-3048; Boncz, Imre/0000-0003-3699-6236; Kajos, Luca Fanni/0000-0002-0574-5787; Ács, Pongrác/0000-0002-4999-7345} } @article{MTMT:35142728, title = {Differences in anthropometric and vertical jump force-time characteristics between U16 and U18 female basketball players}, url = {https://m2.mtmt.hu/api/publication/35142728}, author = {Cabarkapa, Dimitrije and Cabarkapa, Damjana V. and Nagy, Dóra and Szabo, Kenza and Balogh, László and Sáfár, Sándor and Rátgéber, László}, doi = {10.3389/fspor.2024.1425475}, journal-iso = {FRONT SPORTS ACT LIVING}, journal = {FRONTIERS IN SPORTS AND ACTIVE LIVING}, volume = {6}, unique-id = {35142728}, abstract = {Considering the importance of body composition and lower-body strength and power for basketball players' on-court performance, as well as a lack of sports science research focused on female athletes, the purpose of the present investigation was to record the anthropometric and countermovement vertical jump (CMJ) characteristics of top-tier U16 and U18 female basketball players and examine between-group differences in the aforementioned tests. Thirty-two athletes who were a part of the national basketball academy volunteered to participate in the present investigation. Following the body composition assessment conducted via a segmental multifrequency bioimpedance analyzer, athletes performed three CMJs while standing on a force plate system sampling at 1000 Hz. Independent t-test and Mann-Whitney U-test were used to examine between-group differences. The findings reveal significant differences in body composition and lower-body neuromuscular performance characteristics between female basketball players ages 16 and 18. Although no differences were observed in muscle and body fat percentages, the U18 group had significantly greater height, overall body mass (both muscle and fat mass), as well as greater segmental fat-free mass (trunk, both legs and arms), intracellular and extracellular water, and body mass index when compared to their U16 counterparts. On the other hand, the U18 group demonstrated longer eccentric, concentric, and braking phase duration, as well as overall contraction time when compared to the U16 players. In addition, the U18 athletes exhibited higher eccentric mean force and power, concentric impulse, peak power, and mean and peak force.}, keywords = {MUSCLE; PERFORMANCE; Development; METRICS; BODY-COMPOSITION; POWER; force; sport; BIOIMPEDANCE; ECCENTRIC}, year = {2024}, eissn = {2624-9367} } @article{MTMT:34867171, title = {Effects of the Flying Start on Estimated Short Sprint Profiles Using Timing Gates}, url = {https://m2.mtmt.hu/api/publication/34867171}, author = {Jovanović, M. and Cabarkapa, D. and Andersson, H. and Nagy, Dóra and Trunic, N. and Bankovic, V. and Zivkovic, A. and Repasi, R. and Safar, S. and Rátgéber, László}, doi = {10.3390/s24092894}, journal-iso = {SENSORS-BASEL}, journal = {SENSORS}, volume = {24}, unique-id = {34867171}, abstract = {Short sprints are predominantly assessed using timing gates and analyzed through parameters of the mono-exponential equation, including estimated maximal sprinting speed ((Formula presented.)) and relative acceleration ((Formula presented.)), derived maximum acceleration (MAC), and relative propulsive maximal power ((Formula presented.)), further referred to as the No Correction model. 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} } @CONFERENCE{MTMT:34656409, title = {Az edzés utáni szénhidrát visszatöltés hatása az állóképességi sportolók teljesítményére}, url = {https://m2.mtmt.hu/api/publication/34656409}, author = {Csanaky, Lilla and Melczer, Csaba and Nagy, Dóra and Sági, B and Figler, Mária}, booktitle = {Jubileumi Szakkollégiumi Konferencia: Absztrakt kötet}, unique-id = {34656409}, year = {2024}, pages = {12-12}, orcid-numbers = {Melczer, Csaba/0000-0002-8197-0572} } @CONFERENCE{MTMT:33749747, title = {How effective are functional movement chain exercises among athletes and non-athletes?}, url = {https://m2.mtmt.hu/api/publication/33749747}, author = {Krizalkovicová, Zuzana and Nagy, Dóra and Szentpéteri, József László (Joe Petersburger)}, booktitle = {OSCON 5th International Translational Medicine Congress of Students and Young Physicians}, unique-id = {33749747}, year = {2023}, pages = {159} } @article{MTMT:33408202, title = {Comparison of Metabolic Characteristics of Physically Active Individuals with Different Training Habits during Incremental Treadmill Test}, url = {https://m2.mtmt.hu/api/publication/33408202}, author = {Nagy, Dóra and Trunic, Nenad and Prémusz, Viktória and Krutek, László and Lipcsik, Zoltán and Ács, Pongrác}, doi = {10.3390/ijerph20010070}, journal-iso = {INT J ENV RES PUB HE}, journal = {INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH}, volume = {20}, unique-id = {33408202}, issn = {1661-7827}, abstract = {The number of people engaging in self-conducted regular physical activity is increasing, but the effects of home fitness and individually planned workouts on health and metabolism are unknown.
