Excerpt
The purpose of this study was to determine the relationships of laboratory and field measures to middle distance running performance in order to provide coaches and runners with valid and simple physiological monitoring methods. Twelve male and 5 female middle distance runners (mean±SD) age 28±8 yrs were time trialed over 100, 400, 800, 1500 and 5000 m. A treadmill test was used to determine VO2peak (63.1±6.6 ml/kg/min), lactate threshold (LT) (16.4±1.6 km/hr) and running economy at 70% VO2 peak (198± 14 ml/kg/km). Peak oxygen deficit(42.2±5.8 ml/kg) was determined in a separate treadmill test run at 108.6±3.2% of VO2 peak velocity. Performance over 800m was related to LT (r = -0.71), but a combination of 400 m and 5000 m time best predicted 800 m performance (R2 = 0.93). Performance over 1500 m was related to VO2peak (r = -0.80), LT (r = -0.89) and running economy(r=0.50) but a combination of 400 and 5000 m times best predicted 1500 m performance (R2 = 0.91). Performance over 5000 m was related to VO2peak (r = -0.89), LT (r = -0.91) and running economy (r = 0.48) and a combination of LT and VO2 peak best predicted 5000m performance(R2 = 0.89). 800 m (r = 0.67) and 1500 m times (r=0.90) were also related to 5000m performance. These data indicate that tests traditionally used with distance runners (VO2 peak, LT and running economy) may also be used with middle distance runners competing over 1500 and 5000 m. Further, time trial information appears at least as useful as laboratory tests for monitoring middle distance runners.
