Given that side-dominance is associated with differences in motor control, the present study aimed to determine if patches obscuring half of the visual field affect left- and right-side dominant individuals’ gait kinematics and accompanying leg muscle activation differently. Healthy right- ( n = 15, age = 28.2 ± 5.5 years) and left-side ( n = 9, age = 27.9 ± 5.8 years) dominant participants performed 10 min of walking trials on a treadmill at a self-selected speed with 5 min of rest between three randomized trials, i.e., wearing clear glasses or glasses with left-or right half-field eye patching. In addition to a set of spatiotemporal and kinematic gait parameters, the average activity during the separated gait cycle phases, and the start and end of muscle activation in % of the gait cycle were calculated from five muscles in three muscle groups. Our results indicate that gait kinematics of left- and right-side dominant participants were similar both in their dominant and non-dominant legs, regardless of half-field eye patching condition. On the other hand, inter-group differences were found in selected kinematic variables. For instance, in addition to larger but less variable step width, our results suggest larger ankle and knee ROM in right- vs. left-sided participants. Furthermore, medial gastrocnemius and biceps femoris muscle activation showed selected differences at certain phases of the gait cycle between participants’ dominant and non-dominant legs. However, it was also unaffected by the half-field eye patching condition. Moreover, the endpoint of medial gastrocnemius activation was affected by side-dominance, i.e., its activation ended earlier in the non-dominant leg of right- as compared to left-side dominant participants. Our results suggest no major differences in walking gait kinematics and accompanying muscle activation between half-field eye patching conditions in healthy adults; nevertheless, side-dominance may affect biomechanical and neuromuscular control strategies during walking gait.}, year = {2025}, eissn = {2045-2322}, orcid-numbers = {Négyesi, János/0000-0001-5055-3242; Petró, Bálint/0000-0003-3920-5161; Khandoker, Ahsan/0000-0002-0636-1646; Moussa, Mostafa Mohamed/0000-0003-4977-355X; Rácz, Kristóf/0000-0001-5427-1787; Pálya, Zsófia/0000-0002-6295-3160; Grand, László/0000-0001-5391-3266; Kiss, Rita/0000-0003-3607-8435; Nagatomi, Ryoichi/0000-0003-3038-7202} } @article{MTMT:35743388, title = {Objective Measurement Method for Assessing Plank Test Among Female Basketball Players}, url = {https://m2.mtmt.hu/api/publication/35743388}, author = {Pálya, Zsófia and Gál-Pottyondy, Anna and Kiss, Rita}, doi = {10.3311/PPme.39502}, journal-iso = {PERIOD POLYTECH MECH ENG}, journal = {PERIODICA POLYTECHNICA-MECHANICAL ENGINEERING}, volume = {69}, unique-id = {35743388}, issn = {0324-6051}, abstract = {Trunk muscle strength plays a crucial role in the sport-specific movements of basketball players. While the plank test is widely used to assess trunk muscle endurance, its lack of standardization limits its effectiveness in high-performance environments. The study aimed to establish objective criteria for determining when the plank position was no longer maintained and introduced a new variable, postural error (PE). This study involved 23 (age = 15.22 years, weight = 66.3 kg, height = 174 cm) healthy female basketball players from the Hungarian U16 first league. Using optical motion capture, the thoracic kyphosis (TK) and lumbar lordosis (LL) were monitored during the test. The cutting point (CP) was determined based on four mathematical formulas and the estimation of two independent experts. PE was determined based on the area under the curves, which characterizes the magnitude of displacements until the endpoint. According to the difference between the expert-estimated and the calculated CP, the initial angles were calculated as the average of the first 15 seconds, and the CP was set at a ±25° deviation. Additionally, PE was introduced to assess the strategy of maintaining the plank posture, revealing differences in performance even among participants with similar CP times. The present study introduces a new method for determining the test's objective starting angle endpoint and introduces a new variable, PE, to characterize trunk stability, distinguishing between different execution strategies. The findings suggest that this approach provides a more reliable and objective way to assess trunk muscle endurance and core stability.}, year = {2025}, eissn = {1587-379X}, pages = {65-72}, orcid-numbers = {Gál-Pottyondy, Anna/0000-0002-7601-5415; Kiss, Rita/0000-0003-3607-8435} } @article{MTMT:34556996, title = {Comprehensive linear and nonlinear analysis of the effects of spinning on dynamic balancing ability in Hungarian Folk dancers}, url = {https://m2.mtmt.hu/api/publication/34556996}, author = {Pálya, Zsófia and Kiss, Rita}, doi = {10.1186/s13102-024-00850-4}, journal-iso = {BMC SPORTS SCI MED REHAB}, journal = {BMC SPORTS SCIENCE MEDICINE AND REHABILITATION}, volume = {16}, unique-id = {34556996}, issn = {2052-1847}, year = {2024}, eissn = {2052-1847}, orcid-numbers = {Kiss, Rita/0000-0003-3607-8435} } @{MTMT:34176199, title = {Nonlinear dynamic analysis of dynamic balancing ability of Hungarian Folk dancers}, url = {https://m2.mtmt.hu/api/publication/34176199}, author = {Pálya, Zsófia and Molnár, Cecília and Kiss, Rita}, booktitle = {Book of Abstracts. 39th Danubia-Adria Symposium on Advances in Experimental Mechanics. 2023 Hungary}, unique-id = {34176199}, year = {2023}, pages = {118-119}, orcid-numbers = {Kiss, Rita/0000-0003-3607-8435} } @CONFERENCE{MTMT:33304757, title = {Applying Principal Component Analysis to Characterize the Balancing Ability of Elite Synchronized Ice Skaters}, url = {https://m2.mtmt.hu/api/publication/33304757}, author = {Pálya, Zsófia and Petró, Bálint and Kiss, Rita}, booktitle = {ESB2022 27th Congress of the European Society of Biomechanics Abstract Book}, unique-id = {33304757}, year = {2022}, pages = {464-464}, orcid-numbers = {Petró, Bálint/0000-0003-3920-5161; Kiss, Rita/0000-0003-3607-8435} } @article{MTMT:33274589, title = {Assessment of Dynamic Balancing Performance of Synchronized Ice Skaters With Sudden Provocation Test via Principal Component Analysis}, url = {https://m2.mtmt.hu/api/publication/33274589}, author = {Pálya, Zsófia and Petró, Bálint and Kiss, Rita}, doi = {10.1123/jmld.2021-0059}, journal-iso = {J MOTOR LEARN DEV}, journal = {JOURNAL OF MOTOR LEARNING AND DEVELOPMENT}, volume = {10}, unique-id = {33274589}, issn = {2325-3193}, abstract = {Background : Balancing performance can be affected by regular and high-level athletic training, which has not been fully explored in synchronized ice skaters. This study aimed to analyze the dynamic balancing performance by assessing the principal and compensatory movements performed during the sudden provocation tests and evaluating the parameters that characterize the platform’s motion. Method : Twelve young female synchronized ice skaters and 12 female age-matched controls participated. Sudden provocation tests were completed three times in bipedal stance and in single-leg stances, and sport-specific fatigue session was inserted between the repetitions. Results : Significantly more time was necessary to recover balance for both groups after the fatiguing sessions ( p < .05). Interestingly, skaters performed less effectively in the simplest condition (bipedal stance) than the control group ( p < .05). The principal component analysis showed that the first principal movement was the same for both groups. The skater group used the upper body and arms more often to compensate, while the control group’s recovery strategy consisted mainly of abduction of the elevated leg. The damping ratio and the relative variance of the first principal movement showed a negative correlation ( p < .05), suggesting that those with superior balancing effectiveness recruited more compensatory movements.}, year = {2022}, eissn = {2325-3215}, pages = {504-519}, orcid-numbers = {Petró, Bálint/0000-0003-3920-5161; Kiss, Rita/0000-0003-3607-8435} } @article{MTMT:33099479, title = {Biosignal processing methods to explore the effects of side-dominance on patterns of bi- and unilateral standing stability in healthy young adults}, url = {https://m2.mtmt.hu/api/publication/33099479}, author = {Négyesi, János and Petró, Bálint and Salman, Diane Nabil and Khandoker, Ahsan and Katona, Péter and Wang, Ziheng and Almaazmi, Anfal Ibrahim Sanqour Qambar and Hortobágyi, Tibor and Váczi, Márk and Rácz, Kristóf and Pálya, Zsófia and Grand, László and Kiss, Rita and Nagatomi, Ryoichi}, doi = {10.3389/fphys.2022.965702}, journal-iso = {FRONT PHYSIOL}, journal = {FRONTIERS IN PHYSIOLOGY}, volume = {13}, unique-id = {33099479}, abstract = {We examined the effects of side-dominance on the laterality of standing stability using ground reaction force, motion capture ( MoCap ), and EMG data in healthy young adults. We recruited participants with strong right ( n = 15) and left ( n = 9) hand and leg dominance (side-dominance). They stood on one or two legs on a pair of synchronized force platforms for 50 s with 60 s rest between three randomized stance trials. In addition to 23 CoP -related variables, we also computed six MoCap variables representing each lower-limb joint motion time series. Moreover, 39 time- and frequency-domain features of EMG data from five muscles in three muscle groups were analyzed. Data from the multitude of biosignals converged and revealed concordant patterns: no differences occurred between left- and right-side dominant participants in kinetic, kinematic, or EMG outcomes during bipedal stance. Regarding single leg stance, larger knee but lower ankle joint kinematic values appeared in left vs right-sided participants during non-dominant stance. Left-vs right-sided participants also had lower medial gastrocnemius EMG activation during non-dominant stance. While right-side dominant participants always produced larger values for kinematic data of ankle joint and medial gastrocnemius EMG activation during non-dominant vs dominant unilateral stance, this pattern was the opposite for left-sided participants, showing larger values when standing on their dominant vs non-dominant leg, i.e., participants had a more stable balance when standing on their right leg.
