We found that time-course changes in quadriceps isometric torque, creatine kinase activity, and muscle soreness in the two groups were similar. However, recovery in the acute torque deficit was mediated by more favourable electromyographic activity changes in the young group than in the older adults group. Muscle elastic energy storage and re-use assessed with dynamometry was selectively improved in the young group by the end of the protocol. Serum myoglobin concentration increased selectively in old group, and remained elevated with further bouts, suggesting higher sarcolemma vulnerability and less effective metabolic adaptation in the older adults, which, however, did not affect muscle contractility.}, year = {2019}, eissn = {1932-6203}, orcid-numbers = {Atlasz, Tamás/0000-0002-8112-8633; Tékus, Éva/0000-0002-3608-5312} } @article{MTMT:32013631, title = {Normal forces and myofibrillar disruption after repeated eccentric exercise}, url = {https://m2.mtmt.hu/api/publication/32013631}, author = {Hortobágyi, Tibor and Houmard, Joseph and Fraser, David and Dudek, Ronald and Lambert, Jean and Tracy, James}, doi = {10.1152/jappl.1998.84.2.492}, journal-iso = {J APPL PHYSIOL}, journal = {JOURNAL OF APPLIED PHYSIOLOGY}, volume = {84}, unique-id = {32013631}, issn = {8750-7587}, year = {1998}, eissn = {1522-1601}, pages = {492-498}, orcid-numbers = {Hortobágyi, Tibor/0000-0001-5732-7942} } @article{MTMT:31942070, title = {The penetrating power of cosmic-ray shower particles}, url = {https://m2.mtmt.hu/api/publication/31942070}, author = {Jánossy, Lajos}, doi = {10.1017/S0305004100020636}, journal-iso = {MATH PROC CAMBRIDGE}, journal = {MATHEMATICAL PROCEEDINGS OF THE CAMBRIDGE PHILOSOPHICAL SOCIETY}, volume = {34}, unique-id = {31942070}, issn = {0305-0041}, year = {1938}, eissn = {1469-8064}, pages = {614-619} }
