The first purpose of this study was to compare the effects of a cycling bout on running economy with the effects of a running bout on running economy. Four males and four females (M age 28.25 ± 2.2 years) took part in five testing sessions: (a) treadmill and cycling familiarization; (b) measurement of running economy at four speeds (228, 240, 252, and 266 m min'1) and running V02max (M = 65.7 + 2.7 ml kg'1 min'1); (c) remeasurement of running economy and cycling V02max (M - 58.0 ±3.1 ml kg'1 min'1) ; 0 (d) 40 minutes cycling at 80% cycling V02max immediately followed by remeasurement of running economy (cycle-run); and (e) 40 minutes running at 80% running V02max immediately followed by remeasurement of running economy (run-run). A 3 X 4 repeated measures (RM) analysis of variance (ANOVA) was used to compare running economy and lactate concentrations in the rested, cycle-run, and run-run conditions across speeds. When appropriate, Tukey post hoc comparisons were used. Running economy was significantly (p= 002) lower following both the cycling bout and running bout compared to the control condition [cycle-run difference = 1.43 ml kg'1 min'1; run-run difference = 1.76 ml kg'1 min'1] but these did not vary from each other. Lactate concentration did not vary across conditions. The second purpose of this study was to determine the effects of an eight- week training program that included transition training (one endurance and one interval sequential cycle-run session per week) on running economy. Three males and three females (M age 30.17 ± 2.45 years) took part in sessions (b), (c), and (d) from above at four speeds (231, 243, 256, and 270 m min'1) pre- and post-training. Results from a 2 X 2 RM ANOVA showed that V02max did not change significantly (p = .073) in either modality from pre- to post-training (running, pre 68.2 ± 2.8, post 69.4 ±1.8 mlkg'1 min'1; cycling pre 60.9 ± 3,3, post 66.6 ±3.9 mlkg'1 min'1). Results from a 2 X 4 RM ANOVA indicated that running economy did not change significantly (p = .758) from pre- to posttraining in the control condition. Gain score analysis showed that running economy improved at post-training (p - .007) and the greatest improvement occurred at the first speed when compared to all other speeds (p = .000). Lactate concentrations were significantly (p = .002) higher pre- to post-training in the control condition but showed no significant difference in gain scores. It was concluded that running economy declines from control conditions whether the preceding exercise bout is running or cycling and that a cycle-run transition training program of individually constant training volume but increased duration and intensity can improve running economy after cycling.
