Контрольную группу составили юноши студенты, занимающиеся физкультурой не реже двух раз в неделю. Показано, что уровень лактата зависел от уровня физической работоспособности спортсменов единоборцев и накопления продуктов перекисного окисления липидов. Наиболее высокие значения молочной кислоты отмечены на восстановительном этапе.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studies of the lactate level, physical performance and lipid peroxidation in highly skilled athletes in the Far North. The control group consisted of young students engaged in physical exercises at least twice a week. It was shown that the level of lactate depended on the level of physical performance of athletes and the accumulation of lipid peroxidation products. The highest values of lactic acid were noted at the recovery stage.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лактат</kwd><kwd>перекисное окисление липидов</kwd><kwd>физическая работоспособность</kwd><kwd>спортсмены</kwd><kwd>Крайний Север</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lactate</kwd><kwd>lipid peroxidation</kwd><kwd>physical performance</kwd><kwd>athletes</kwd><kwd>Far North</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Артахинова С.Р.
