Here, we examined if such an age by task difficulty interaction in motor cortical excitability also occurs in easier standing tasks. METHODS: Fourteen young (23 +/- 2.7 years) and fourteen old (65 +/- 4.1 years) adults received transcranial magnetic brain stimulation and peripheral nerve stimulation, while they stood with or without support on a force platform. RESULTS: In the soleus, we found that SICI was lower in unsupported (35 % inhibition) vs. supported (50 %) standing (p = 0.007) but similar in young vs. old adults (p = 0.591). In the tibialis anterior, SICI was similar between conditions (p = 0.597) but lower in old (52 %) vs. young (72 %) adults (p = 0.030). Age and standing with or without support did not affect the Hoffmann reflex in the soleus. CONCLUSIONS: The current data suggest that the motor cortex is involved in standing control, and that its role becomes more prominent with an increase in task difficulty.}, year = {2016}, eissn = {1439-6327}, pages = {959-967}, orcid-numbers = {Négyesi, János/0000-0001-5055-3242; Hortobágyi, Tibor/0000-0001-5732-7942} } @article{MTMT:3054178, title = {Function of the flexor hallucis longus muscle - what do we know}, url = {https://m2.mtmt.hu/api/publication/3054178}, author = {Péter, Annamária and Hegyi, András and Tihanyi, József and Cronin, N J}, journal-iso = {M SPORTTUD SZLE}, journal = {MAGYAR SPORTTUDOMÁNYI SZEMLE}, volume = {17}, unique-id = {3054178}, issn = {1586-5428}, year = {2016}, pages = {46-50} } @article{MTMT:3054409, title = {Direct and crossed effects of somatosensory electrical stimulation on motor learning and neuronal plasticity in humans}, url = {https://m2.mtmt.hu/api/publication/3054409}, author = {Veldman, MP and Zijdewind, I and Solnik, S and Maffiuletti, NA and Berghuis, KMM and Javet, M and Négyesi, János and Hortobágyi, Tibor}, doi = {10.1007/s00421-015-3248-z}, journal-iso = {EUR J APPL PHYSIOL}, journal = {EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY}, volume = {115}, unique-id = {3054409}, issn = {1439-6319}, abstract = {Purpose Sensory input can modify voluntary motor function. We examined whether somatosensory electrical stimulation (SES) added to motor practice (MP) could augment motor learning, interlimb transfer, and whether physiological changes in neuronal excitability underlie these changes. Methods Participants (18-30 years, n = 31) received MP, SES, MP + SES, or a control intervention. Visuomotor practice included 300 trials for 25 min with the right-dominant wrist and SES consisted of weak electrical stimulation of the radial and median nerves above the elbow. Single-and double-pulse transcranial magnetic stimulation (TMS) metrics were measured in the intervention and nonintervention extensor carpi radialis. Results There was 27 % motor learning and 9 % (both p < 0.001) interlimb transfer in all groups but SES added to MP did not augment learning and transfer. Corticospinal excitability increased after MP and SES when measured at rest but it increased after MP and decreased after SES when measured during contraction. No changes occurred in intra-cortical inhibition and facilitation. MP did not affect the TMS metrics in the transfer hand. In contrast, corticospinal excitability strongly increased after SES with MP + SES showing sharply opposite of these effects. Conclusion Motor practice and SES each can produce motor learning and interlimb transfer and are likely to be mediated by different mechanisms. The results provide insight into the physiological mechanisms underlying the effects of MP and SES on motor learning and cortical plasticity and show that these mechanisms are likely to be different for the trained and stimulated motor cortex and the non-trained and non-stimulated motor cortex.}, keywords = {median nerve; primary motor cortex; transcranial magnetic stimulation; CORTEX EXCITABILITY; CHRONIC STROKE; paired associative stimulation; corticospinal excitability; INTERVAL INTRACORTICAL INHIBITION; INTERHEMISPHERIC INHIBITION; CORTICOMOTOR EXCITABILITY; USE-DEPENDENT PLASTICITY; PERIPHERAL-NERVE STIMULATION; Motor evoked potential; Interlimb transfer}, year = {2015}, eissn = {1439-6327}, pages = {2505-2519}, orcid-numbers = {Négyesi, János/0000-0001-5055-3242; Hortobágyi, Tibor/0000-0001-5732-7942} } @article{MTMT:2990192, title = {The EMG activity-acceleration relationship to quantify the optimal vibration load when applying synchronous whole-body vibration}, url = {https://m2.mtmt.hu/api/publication/2990192}, author = {Di Giminiani, R and Masedu, F and Padulo, J and Tihanyi, József and Valenti, M}, doi = {10.1016/j.jelekin.2015.09.004}, journal-iso = {J ELECTROMYOGR KINES}, journal = {JOURNAL OF ELECTROMYOGRAPHY AND KINESIOLOGY}, volume = {25}, unique-id = {2990192}, issn = {1050-6411}, abstract = {Purpose: To date are lacking methodological approaches to individualizing whole-body vibration (WBV) intensity. The aim of this study was: (1) to determine the surface-electromyography-root-mean-square (sEMGRMS)-acceleration load relationship in the vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), lateral gastrocnemius (LG) muscles during synchronous WBV, and (2) to assess the reliability of the acceleration corresponding to the maximal sEMGRMS. Methods: Twenty-five sportsman voluntarily took part in this study with a single-group, repeated-measures design. All subjects postured themselves in an isometric half-squat during nine trials in the following conditions: no vibrations and random vibrations of different acceleration loads (from 0.12 to 5.72g). Results: The sEMGRMS were dependent on the acceleration loads in the VL (p=0.0001), LG (p=0.0001) and VM (p=0.011) muscles; while RF was not affected by the acceleration loads (p=0.508). The comparisons among the sEMGRMS-accelerations relationships revealed a significant difference between the LG and the others muscles (p=0.001). No significant difference was found between the different thigh muscles (p>0.05). The intra-class correlation coefficient ranged from 0.87 to 0.99 for the measurements performed on the LG, VL and VM. Conclusions: The sEMGRMS-acceleration relationship in the VL, VM and LG is a reliable test to individualize the WBV intervention. © 2015 Elsevier Ltd.}, keywords = {Exercise Test; Aged; Adult; Male; ARTICLE; human; Measurement; priority journal; controlled study; normal human; human experiment; Experimental study; Methods; Electromyography; Reliability; Muscle Contraction; motor performance; volunteer; correlation coefficient; Acceleration; DOSE-RESPONSE; muscle isometric contraction; functional assessment; athlete; whole body vibration; vastus lateralis muscle; gastrocnemius muscle; individualization; rectus femoris muscle; muscle function; repeat procedure; muscle excitation; statistical concepts; vastus medialis muscle; Internal-external load}, year = {2015}, eissn = {1873-5711}, pages = {853-859} } @inproceedings{MTMT:2941253, title = {Az Ayres-féle terápián alapuló mozgásfejlesztés biológiai rizikófaktorral született óvodások körében}, url = {https://m2.mtmt.hu/api/publication/2941253}, author = {Csirkés, Zsolt and Ramocsa, Gábor and Földi, Rita and Bretz, Károly and Hamar, Pál}, booktitle = {Színes sporttudomány}, unique-id = {2941253}, year = {2015}, pages = {248-258} } @article{MTMT:2919751, title = {Egy passzív testedzési forma, a pulzáló elektromágneses terápia (EMF) hatásai idős patkányokban}, url = {https://m2.mtmt.hu/api/publication/2919751}, author = {Téglás, Tímea and Bretz, Károly and Nyakas, Csaba}, journal-iso = {M SPORTTUD SZLE}, journal = {MAGYAR SPORTTUDOMÁNYI SZEMLE}, volume = {16}, unique-id = {2919751}, issn = {1586-5428}, year = {2015}, pages = {68}, orcid-numbers = {Nyakas, Csaba/0000-0003-3756-0186} }
