摘要: Fifteen women (20- to 23-yr.-old), engaged in an intensive 6- 8-wk. endurance running program, progressively increased distance from 20 miles during the first week 50 fifth and thereafter. Before (T1), (T2), after training (T3), submaximal treadmill runs of 1-hr. duration subdivided into three successive 20-min. segments were completed at approximately 60, 70, 80% maximal oxygen uptake, respectively. Ratings perceived exertion (RPE) differentiated obtain local (L), central (C), over-all (O) responses these segments. Subjects rated effort final 30 sec. each 5-min. interval. Upon completion exercise segment, blood samples drawn for analysis lactate (Hla), epinephrine (E), norepinephrine (NE) determine relationship between RPEs stress markers. Endurance significantly lowered ratings T1 T3 but ...
