A 1-day maximal lactate steady-state assessment protocol for trained runners.

摘要: A 1-day maximal lactate steady-state assessment protocol for trained runners. Med. Sci. Sports Exerc., Vol. 31, No. 9, pp. 1336-1341, 1999. Identification of the steady state (MLSS) involves multiple days testing. Heart rate (HR), rating perceived exertion (RPE), breathing frequency (bf), and race pace may be useful in estimating MLSS, thus allowing testing to occur a single day. The purpose this investigation was design single-session determining MLSS using HR, RPE, bf, as predictors. Twelve endurance athletes (mean ± SD, JOURNAL/mespex/beta/00005768-199909000-00018/ENTITY_OV0312/v/2016-09-20T214635Z/r/image-pngO2max 64.6 7.8 mL·kg−1·min−1) performed run two 27-min validation runs on treadmill. Running velocity at 87% HRmax, RPE 12, bf 32 breaths·min−1, were used starting point Blood collected every 3 min each 9-min stage analyzed (La) concentration. associated with determined average La accumulation. Validation 7.5 m·min−1 below above protocol-determined MLSS. If slower exhibited faster an accumulation La, then value considered valid. The successful predicting 9 out 12 subjects (P ≤ 0.05). The proposed employing can identify one session.
