Popis: The relationship between the occurrence of stress fractures, training parameters and nutritional regimes was assessed using an anonymous retrospective questionnaire in elite international level figure skaters representing all 62 member federations of the International Skating Union. The response rate was 62% in female and 67% in male figure skaters. Results were obtained from both junior and senior figure skaters (245 females and 167 males) with a median age of 16 yrs. for females and 18 yrs. for males. With regard to the subjects, 41 females (16.7%) and 25 males (13.8%) reported stress fractures in the last years of training and competing in figure skating. In female junior skaters, 75% of the reported stress fractures occurred in singles, 20.8% in pairs, and 4.2% in ice dancers. Among male junior skaters, 80% of the reported stress fractures occurred in singles, 13.3% in pairs, and 6.7% in ice dancers. In senior females, 70.6% of the reported stress fractures occurred in singles, 23.5% in pairs, and 5.9% in ice dancers, while among male senior skaters, 80% of the reported stress fractures occurred in singles, with 10% in pairs and in ice dancers. Regardless of the discipline, the majority of all stress fractures were located in the tibial bone. There was no difference between the incidence of stress fractures during summer or winter training, and this incidence was in no way related to dietary habits. All figure skaters attributed the occurrence of stress fractures to changes in their training and competition programs. In women, there was no statistically significant increased incidence of stress fractures in those with menstrual irregularities. Important factors that appear to contribute to the occurrence of stress fractures in elite figure skaters are increased physiological demands, including increasing rotations and height of jumps, as well as more rigorous training and competitive schedules throughout the skating season.
Kod vrhunskih umjetničkih klizača promatrana je povezanost izmeðu pojave prijeloma zamora, parametara trenažnog procesa te prehrambenih navika. Anonimnim retrospektivnim upitnikom proveli smo istraživanje meðu svim članicama, njih 62, Meðunarodne klizačke federacije. Povratnu smo informaciju dobili od 62% ženskih te 67% muških umjetnièkih klizača. Rezultati su dobiveni od juniorskih i seniorskih vrhunskih umjetničkih klizača (245 ženskih i 167 muških), srednje životne dobi od 16 godina za žene i 18 godina za muške ispitanike. Prijelomi zamora pronaðeni su kod 41 umjetničke klizačice (16.7%) i 25 umjetnička klizača (13.8%) koji su dijagnosticirani u posljednjim godinama njihovog treniranja i nastupanja. Kod ženskih juniorki 75% prijeloma zamora bilo je kod klizačica koje nastupaju samostalno, 20.8% kod sportskih parova i 4.2% kod plesnih parova. Kod muških juniora 80% prijelomi zamora javilo se kod klizača koji samostalno nastupaju, 13.3% kod sportskih parova i 6.7% kod plesnih parova. Kod seniorki, 70.6% prijeloma zamora javilo se kod onih koje samostalno nastupaju, 23.5% kod sportskih parova i 5.9% kod plesnih parova, dok se kod seniora 80% prijeloma zamora javilo kod onih koji samostalno nastupaju, a 10% kod sportskih te plesnih parova. Bez obzira na disciplinu umjetnièkog klizanja, većina prijeloma zamora lokalizirana je na tibiji. Nije bilo razlike izmeðu pojave prijeloma zamora tijekom ljetnog i zimskog režima treniranja. Takoðer nije pronaðena korelacija izmeðu pojave prijeloma zamora i prehrambenih navika klizača. U žena nije pronaðena statistièčki značajna razlika izmeðu povećane učestalosti prijeloma zamora i menstrualnih neregularnosti. čimbenici koji najviše utječu na pojavu prijeloma zamora kod umjetnièkih klizača povezani su s povećanim fizièčkim naporima koji uključuju povećan broj rotacija i visinu kod pojedinog klizačkog skoka, povećanje količine napora tijekom pojedinog trenažnog procesa kao i povećan broj natjecanja tijekom jedne klizačke sezone.
